Question 41

Which ISE feature allows the network to enforce different access policies for different types of endpoints such as laptops, printers, and IP phones?

A) Profiling
B) Posture
C) BYOD
D) TrustSec

Answer: A) Profiling

Explanation:

The correct answer is A) Profiling. Cisco ISE Profiling is the feature that allows the identification of endpoints based on attributes such as device type, operating system, MAC address, and manufacturer. Profiling helps the network enforce differentiated access policies for diverse endpoint types. By understanding whether a device is a laptop, printer, or IP phone, ISE can dynamically assign VLANs, ACLs, or downloadable access policies appropriate for the device’s role and security requirements. Profiling collects information from multiple sources including RADIUS, DHCP, SNMP, HTTP, and NetFlow to accurately classify devices.

A) Profiling is correct because it provides granular visibility into the network and allows administrators to create access rules tailored to each device type. For example, printers may be restricted to a specific VLAN with minimal access, while laptops belonging to employees may receive broader network access. Profiling data is critical for authorization policies to make informed decisions based on endpoint attributes. Profiling also supports BYOD and guest scenarios by identifying unknown devices and applying appropriate access restrictions.

B) Posture is incorrect because posture evaluates the security compliance of endpoints rather than their type. Posture ensures that devices have required security software, firewalls, and patches, but it does not inherently identify device type. Posture complements profiling by determining if an endpoint meets security policies, but device identification is performed through profiling.

C) BYOD is incorrect because BYOD handles onboarding and provisioning of personal employee devices. BYOD may leverage profiling to determine device type, but its primary function is registration, certificate deployment, and access provisioning for personal endpoints. It does not itself classify endpoints for access decisions.

D) TrustSec is incorrect because TrustSec is used for network segmentation through Security Group Tags (SGTs). TrustSec enforces access control based on identity or role but does not directly identify endpoint types. TrustSec policies rely on data such as profiling results, posture checks, or authentication decisions to assign SGTs appropriately.

Profiling is essential in complex enterprise networks where multiple device types coexist. By providing detailed device identification, profiling allows administrators to implement tailored access policies, improve security, and optimize network resource utilization. For example, IoT devices such as IP cameras may be restricted to specific network segments, preventing lateral movement if compromised. Employee laptops may be granted access based on both role and posture compliance, ensuring security without impacting usability. Profiling integrates with posture, BYOD, and authorization policies to deliver dynamic, context-aware access control. Profiling is the mechanism responsible for identifying endpoints and enabling differentiated network access policies, while posture, BYOD, and TrustSec serve complementary but distinct functions in network security.

Question 42

Which ISE policy component is responsible for evaluating endpoint health and determining access restrictions if non-compliant?

A) Authorization Policy
B) Posture Policy
C) Profiling Policy
D) Authentication Policy

Answer: B) Posture Policy

Explanation:

The correct answer is B) Posture Policy. Posture Policy in Cisco ISE evaluates the security compliance of endpoints before granting network access. Posture assessment checks include antivirus presence, firewall status, operating system patches, and other security-related attributes. Based on the evaluation, ISE can enforce access restrictions such as VLAN assignment, ACL application, or redirecting non-compliant devices to remediation portals where users can resolve compliance issues.

A) Authorization Policy is incorrect because authorization policies enforce access decisions but rely on input from posture, profiling, and authentication. While authorization may determine access based on compliance, the assessment itself is conducted by the posture policy. Authorization is the decision-making component, not the compliance evaluator.

B) Posture Policy is correct because it specifically defines which security requirements must be met by endpoints. Posture policies can be agent-based, requiring a software agent on the endpoint to report compliance, or agentless, using network protocols to assess compliance without software installation. Agent-based posture provides detailed insights into endpoint health, while agentless posture is ideal for BYOD and guest devices. Posture policies are highly configurable, allowing administrators to define actions for compliant and non-compliant devices. Non-compliant devices may be quarantined, redirected to remediation portals, or given limited access to ensure the network remains secure.

C) Profiling Policy is incorrect because profiling identifies the type of device, operating system, and manufacturer, but does not evaluate compliance. Profiling data is used by authorization and posture policies but is not itself responsible for determining health-based access restrictions.

D) Authentication Policy is incorrect because authentication validates the identity of the endpoint or user. While authentication ensures that only known or authorized users and devices can request network access, it does not assess security posture or apply restrictions based on compliance.

Posture Policy is critical for enforcing security compliance across diverse network devices. It enables organizations to maintain a secure network by ensuring that endpoints meet security standards before receiving full access. By integrating posture with authorization policies, ISE can dynamically grant, restrict, or redirect endpoints based on real-time compliance status. For example, a laptop without updated antivirus signatures could be placed in a restricted VLAN and given access only to remediation servers until compliance is restored. Posture policies enhance security, reduce the risk of malware propagation, and maintain network integrity. Posture Policy is the mechanism responsible for evaluating endpoint health and enforcing access restrictions, whereas authorization, profiling, and authentication perform complementary but distinct roles.

Question 43

Which protocol is primarily used by Cisco ISE to enforce network access on switches and wireless controllers?

A) TACACS+
B) RADIUS
C) SNMP
D) HTTP

Answer: B) RADIUS

Explanation:

The correct answer is B) RADIUS. RADIUS (Remote Authentication Dial-In User Service) is the primary protocol Cisco ISE uses to enforce network access for endpoints connecting to switches, routers, and wireless controllers. RADIUS enables authentication, authorization, and accounting (AAA) for network users and devices. When an endpoint attempts to connect, RADIUS communicates with ISE to validate credentials, evaluate policies, and return access decisions such as VLAN assignments, ACLs, or downloadable policies. This protocol is critical for dynamic network access control and integration with posture, BYOD, and TrustSec policies.

A) TACACS+ is incorrect because TACACS+ is primarily used for administrative access to network devices. It allows granular command-level authorization for network administrators but is not used for general endpoint access or policy enforcement for end-users.

B) RADIUS is correct because it is designed to handle AAA for network access. RADIUS messages carry attributes such as VLAN assignments, downloadable ACLs, and session timeout information. It integrates with ISE to provide real-time, context-aware access decisions based on identity, role, and posture compliance.

C) SNMP is incorrect because SNMP is a network monitoring protocol. While it can provide information for device profiling or health monitoring, it does not enforce access control or evaluate AAA policies.

D) HTTP is incorrect because HTTP is used for web-based portals, such as BYOD registration or guest self-service portals. While HTTP facilitates portal-based onboarding, it is not the primary protocol for enforcing network access on switches or wireless controllers.

RADIUS is essential for dynamic access control in Cisco ISE deployments. It enables the application of policies based on user identity, device type, and posture, allowing secure segmentation and access restrictions. RADIUS ensures endpoints are correctly authenticated and authorized before granting network privileges, which is crucial in enterprise environments with diverse devices and user types. It integrates seamlessly with posture assessment and authorization policies to enforce compliance-driven access decisions.

Question 44

Which ISE node is responsible for policy enforcement and real-time processing of authentication requests?

A) Policy Administration Node (PAN)
B) Policy Service Node (PSN)
C) Monitoring and Troubleshooting Node (MnT)
D) Guest Node

Answer: B) Policy Service Node (PSN)

Explanation:

The correct answer is B) Policy Service Node (PSN). In Cisco ISE architecture, PSNs are the enforcement nodes responsible for processing authentication and authorization requests in real-time. When an endpoint attempts to connect to the network, the PSN evaluates credentials, applies authorization rules, and enforces posture compliance. It then communicates with the network device, such as a switch or wireless controller, to grant access, assign VLANs, or apply ACLs. PSNs handle high volumes of RADIUS and TACACS+ requests, making them essential for scalable deployments.

A) PAN is incorrect because the PAN is responsible for configuration and policy creation. PAN nodes do not enforce policies or process real-time authentication requests. The PAN stores and distributes policy configurations to PSNs.

B) PSN is correct because it directly enforces authentication, authorization, and posture policies. It acts as the operational interface between ISE and the network infrastructure. PSNs can scale horizontally to handle large enterprise deployments and ensure continuous access enforcement.

C) MnT is incorrect because Monitoring and Troubleshooting nodes are used for logging, reporting, and auditing. MnTs collect AAA data, posture results, and guest activity, but they do not participate in real-time policy enforcement.

D) Guest Node is incorrect because Guest Nodes provide self-service portals for temporary user onboarding. While Guest Nodes integrate with authorization policies for guest access, they do not enforce real-time network access for corporate endpoints.

PSNs are critical for the operational functionality of ISE. They ensure that authentication and authorization decisions are applied dynamically, that posture evaluations are enforced, and that access is granted based on real-time policy evaluation. By separating configuration management (PAN) from policy enforcement (PSN), Cisco ISE achieves scalability, high availability, and centralized management.

Question 45

Which ISE feature allows devices to automatically receive network policies based on device type, location, and user role?

A) Profiling
B) Authorization Policy
C) Posture
D) TrustSec

Answer: B) Authorization Policy

Explanation:

The correct answer is B) Authorization Policy. Authorization policies in Cisco ISE determine the type of network access a device receives based on a variety of attributes. These attributes can include device type, user role, location, posture compliance, and group membership. By evaluating these attributes, the authorization policy dynamically applies network access decisions such as VLAN assignment, downloadable ACLs, and role-based access. Authorization policies are critical for enforcing security, controlling access based on identity and device context, and integrating other ISE features such as Posture, Profiling, and TrustSec.

A) Profiling is incorrect because profiling identifies and classifies devices based on type, operating system, manufacturer, and other attributes, but it does not enforce network access policies. Profiling data is used as input for authorization policies, which then determine the specific access rules for the device. While profiling provides visibility, it does not itself assign VLANs or enforce access.

B) Authorization Policy is correct because it is the component responsible for making decisions on what network access should be granted. For example, a laptop belonging to the finance department could receive full network access, while a printer may be restricted to a separate VLAN with minimal privileges. Authorization policies integrate input from profiling, posture, and authentication to make granular, context-aware access decisions. These policies are evaluated in real-time by Policy Service Nodes (PSNs) when a device connects to the network. Authorization policies can also redirect non-compliant devices to remediation portals and apply time-based or location-based restrictions, providing fine-grained control over network access.

C) Posture is incorrect because posture evaluates whether a device meets corporate security requirements, such as antivirus installation, firewall configuration, and OS patch levels. While posture results influence the authorization policy decision, posture itself does not assign network access directly. It is a compliance assessment mechanism, not an access enforcement mechanism.

D) TrustSec is incorrect because TrustSec focuses on network segmentation and identity-based access using Security Group Tags (SGTs). TrustSec enforces access across network devices but relies on authorization policies to determine which SGTs should be assigned to which devices or users. TrustSec is an enforcement mechanism that complements authorization policies rather than replacing them.

In practical deployments, authorization policies allow administrators to define flexible, role-based access for various device types, users, and contexts. For example, employees accessing the network from corporate laptops may receive full access to internal resources, while BYOD devices are assigned limited access with VLAN restrictions. By integrating posture, profiling, and identity information, authorization policies dynamically enforce security, ensure compliance, and minimize risk. Authorization policies are central to Cisco ISE’s access control framework, enabling consistent enforcement across wired and wireless networks, making B) Authorization Policy the correct answer while profiling, posture, and TrustSec provide supporting but distinct functionality.

Question 46

Which ISE protocol provides centralized authentication, authorization, and accounting for guest and BYOD endpoints?

A) TACACS+
B) RADIUS
C) SNMP
D) HTTP

Answer: B) RADIUS

Explanation:

The correct answer is B) RADIUS. Cisco ISE uses RADIUS (Remote Authentication Dial-In User Service) to provide AAA services for guest, BYOD, and corporate endpoints connecting to network devices such as switches and wireless controllers. RADIUS messages carry information about authentication credentials, authorization rules, and accounting data, allowing ISE to enforce network access dynamically. RADIUS supports integration with posture assessment, BYOD workflows, and TrustSec policies, ensuring secure and context-aware access decisions.

A) TACACS+ is incorrect because TACACS+ is primarily used for administrative access to network devices. It provides detailed command-level authorization for network administrators but is not the primary protocol for guest or endpoint network access.

B) RADIUS is correct because it is the standard protocol for network access control, supporting authentication, authorization, and accounting for both wired and wireless endpoints. RADIUS allows ISE to assign VLANs, apply downloadable ACLs, enforce posture-based restrictions, and maintain accounting logs for auditing purposes. RADIUS ensures that devices are authenticated and granted appropriate access based on identity, role, and compliance.

C) SNMP is incorrect because SNMP is a monitoring protocol used to collect network and device information. While SNMP data can support profiling, it does not authenticate endpoints or enforce access policies.

D) HTTP is incorrect because HTTP is used for web portals such as BYOD registration or guest onboarding. While HTTP allows users to interact with ISE portals, it does not provide AAA enforcement for network access.

RADIUS is fundamental for Cisco ISE because it bridges the gap between policy decisions and enforcement on network devices. By leveraging RADIUS, ISE can evaluate real-time authentication requests, apply authorization rules, and log accounting data, ensuring consistent, secure access for both corporate and guest users. RADIUS enables dynamic access control, making it the backbone protocol for endpoint and guest access enforcement in ISE deployments.

Question 47

Which ISE node is responsible for logging, reporting, and troubleshooting network access and endpoint compliance?

A) Policy Administration Node (PAN)
B) Policy Service Node (PSN)
C) Monitoring and Troubleshooting Node (MnT)
D) Guest Node

Answer: C) Monitoring and Troubleshooting Node (MnT)

Explanation:

The correct answer is C) Monitoring and Troubleshooting Node (MnT). MnT nodes in Cisco ISE are designed to collect, store, and analyze logs from all authentication, authorization, and posture events across the network. MnT nodes provide administrators with dashboards, reports, and troubleshooting tools to monitor endpoint compliance, guest access, and BYOD activity. They centralize log collection from multiple PSNs and provide visibility for auditing and regulatory compliance.

A) PAN is incorrect because the Policy Administration Node handles configuration and policy deployment, not logging or reporting. PAN nodes distribute policies to PSNs but do not provide centralized visibility into network activity.

B) PSN is incorrect because PSNs enforce real-time policies. While PSNs generate event logs for RADIUS and TACACS+ requests, MnT nodes aggregate, analyze, and present this data for monitoring, reporting, and troubleshooting.

C) MnT is correct because it collects logs from PSNs, guest portals, and BYOD devices, providing a single view of network activity. MnT nodes support report generation for audits, compliance, and operational analysis. Administrators can detect authentication failures, posture non-compliance, and suspicious access attempts. MnT nodes also provide historical data for forensic analysis and capacity planning.

D) Guest Node is incorrect because Guest Nodes provide self-service onboarding portals for temporary users. While Guest Nodes generate logs specific to guest activity, they do not provide comprehensive network-wide monitoring or reporting.

MnT nodes are essential for organizations needing visibility into their network access environment. They enable administrators to track authentication and authorization events, posture compliance, guest activity, and BYOD registration. By centralizing reporting and troubleshooting, MnT nodes support operational efficiency, security audits, and regulatory compliance. MnTs complement PSNs and PANs by providing insights and analytics, ensuring administrators have a complete understanding of network activity.

Question 48

Which Cisco ISE feature enforces network segmentation using Security Group Tags (SGTs)?

A) BYOD
B) TrustSec
C) Posture
D) Guest Access

Answer: B) TrustSec

Explanation:

The correct answer is B) TrustSec. Cisco TrustSec is an identity-based network segmentation solution that uses Security Group Tags (SGTs) to enforce access control. SGTs are applied to users, devices, or endpoints and determine which resources they can access. Network devices such as switches and routers enforce policies based on SGTs rather than IP addresses, enabling scalable and dynamic access control. TrustSec can work with authorization policies to assign SGTs based on user role, device type, or compliance status.

A) BYOD is incorrect because BYOD focuses on onboarding personal devices and provisioning access credentials. BYOD may leverage TrustSec for dynamic policy assignment, but BYOD itself does not implement SGT-based segmentation.

B) TrustSec is correct because it provides role-based access control through SGTs. TrustSec allows administrators to define security groups, map users or devices to those groups, and enforce policies consistently across wired and wireless networks. For example, finance devices may have one SGT allowing access to accounting servers, while guest devices have another SGT restricted to internet access. TrustSec reduces reliance on VLANs and IP-based ACLs, simplifies segmentation, and enhances security by tying access to identity and compliance rather than static network parameters.

C) Posture is incorrect because posture evaluates endpoint health for compliance. While posture results can influence TrustSec assignments, posture itself does not enforce network segmentation or assign SGTs.

D) Guest Access is incorrect because it handles temporary access for visitors or contractors, not identity-based network segmentation. Guest access may be combined with TrustSec for isolation, but TrustSec is the feature providing scalable SGT-based enforcement.

TrustSec enables dynamic and flexible access control in modern enterprise networks. By integrating with authorization policies and posture, TrustSec ensures that access decisions are identity-aware and context-sensitive. It simplifies policy management and enhances security, particularly in large and complex environments.

Question 49

Which ISE node handles self-service registration and approval for temporary network users?

A) Policy Administration Node (PAN)
B) Guest Node
C) Policy Service Node (PSN)
D) Monitoring Node (MnT)

Answer: B) Guest Node

Explanation:

The correct answer is B) Guest Node. Guest Nodes in Cisco ISE provide portals for self-service registration, sponsor approval workflows, and voucher-based access for temporary users such as contractors or visitors. Guest Nodes can assign VLANs, apply ACLs, and enforce time-based restrictions to isolate guest traffic from corporate resources.

A) PAN is incorrect because it handles policy configuration and deployment. PANs do not manage guest registration or approval workflows.

B) Guest Node is correct because it provides self-service portals where temporary users can request access, employees can sponsor guests, and network access can be assigned in a controlled manner. Guest Nodes integrate with authorization policies to enforce restricted network access while maintaining usability for visitors.

C) PSN is incorrect because PSNs enforce authentication and authorization policies but do not provide self-service portals for guest users.

D) MnT is incorrect because MnT nodes collect logs and provide reporting, but do not handle guest onboarding or registration workflows.

Guest Nodes ensure secure, controlled, and auditable access for temporary users. They complement other ISE components such as PSNs, PANs, and MnTs, providing a complete guest access solution while maintaining network security.

Question 50

Which Cisco ISE feature evaluates endpoint compliance and can redirect non-compliant devices to remediation portals?

A) Profiling
B) Posture
C) BYOD
D) TrustSec

Answer: B) Posture

Explanation:

 

The correct answer is B) Posture. Cisco ISE Posture is the feature that evaluates whether an endpoint meets security compliance policies before granting network access. Compliance checks can include antivirus presence, firewall configuration, operating system updates, patch levels, and other security controls. If an endpoint fails these checks, ISE can dynamically restrict network access or redirect the device to a remediation portal, where the user can update software, install missing patches, or enable required security features. This ensures that non-compliant devices cannot compromise corporate networks while providing a path to regain full access once compliance is achieved.

A) Profiling is incorrect because profiling identifies the type of device, its operating system, and manufacturer, but it does not evaluate security compliance or redirect devices for remediation. Profiling is a supporting input for authorization and posture policies but does not enforce health-based access restrictions.

B) Posture is correct because it is specifically designed to assess compliance and enforce conditional network access. Posture can be agent-based, where a small client software is installed on endpoints, or agentless, which evaluates endpoint compliance without requiring software. Agent-based posture provides detailed checks for Windows, macOS, or mobile devices, while agentless posture uses network protocols like DHCP, SNMP, or RADIUS for assessments. Once the endpoint is evaluated, the results are communicated to the Policy Service Node (PSN), which enforces authorization policies based on compliance. Non-compliant endpoints may be placed in restricted VLANs, denied full access, or redirected to remediation portals, allowing users to resolve issues before receiving standard network access.

C) BYOD is incorrect because BYOD handles onboarding and provisioning of personal devices, including certificate deployment and Wi-Fi configuration. BYOD may leverage posture checks to enforce compliance on employee devices, but its main function is device registration and provisioning, not compliance evaluation.

D) TrustSec is incorrect because TrustSec enforces network segmentation and access control using Security Group Tags (SGTs). TrustSec does not assess endpoint compliance or redirect non-compliant devices to remediation portals; it focuses on identity-based network enforcement.

Posture is critical for enterprises with diverse endpoints and security requirements. By integrating posture with authorization policies, administrators can implement dynamic access controls that respond to real-time compliance status. For example, a laptop without an updated antivirus may be restricted to a remediation VLAN while users download the necessary updates. Posture ensures that endpoints do not introduce vulnerabilities into the network, reduces the risk of malware propagation, and maintains compliance with organizational security policies. Posture is the mechanism responsible for assessing compliance and enforcing remediation workflows, while profiling, BYOD, and TrustSec serve complementary but distinct purposes.

Question 51

 

Which ISE component manages configuration, policy creation, and deployment across other nodes?

A) Policy Service Node (PSN)
B) Policy Administration Node (PAN)
C) Monitoring and Troubleshooting Node (MnT)
D) Guest Node

Answer: B) Policy Administration Node (PAN)

Explanation:

The correct answer is B) Policy Administration Node (PAN). In Cisco ISE architecture, the PAN centralizes administration tasks, including configuration, policy creation, and distribution to enforcement nodes (PSNs). All authentication, authorization, BYOD, guest access, posture, and TrustSec policies are defined on the PAN. Once configured, the PAN replicates the policies to PSNs to enforce them in real-time. Centralized management ensures consistency across distributed deployments and simplifies policy updates, providing a single point for administrative control.

A) PSN is incorrect because PSNs enforce policies in real-time. PSNs process RADIUS and TACACS+ requests, evaluate authorization, and apply posture results, but they do not create or deploy configurations. PSNs depend on the PAN to receive updated policies and configuration changes.

B) PAN is correct because it is the authoritative administrative node. Administrators use the PAN to create authentication rules, authorization policies, posture checks, BYOD workflows, and guest access configurations. The PAN stores system certificates, manages node groups, and handles integration with external identity sources such as Active Directory or LDAP. Centralizing configuration on the PAN reduces administrative errors, simplifies large-scale deployments, and ensures consistent policy enforcement.

C) MnT is incorrect because Monitoring and Troubleshooting nodes focus on logging, reporting, and operational visibility. MnTs collect AAA logs, posture assessments, and guest activity for auditing, troubleshooting, and compliance, but they do not manage configuration or policy deployment.

D) Guest Node is incorrect because Guest Nodes provide portals for temporary user onboarding, self-service registration, and sponsor approval workflows. Guest Nodes do not manage or distribute system-wide policies or configuration.

The PAN plays a crucial role in large-scale Cisco ISE deployments by separating administrative tasks from enforcement. This ensures scalability, high availability, and consistent policy application across multiple PSNs. It also allows integration with external systems, such as Active Directory, for identity-based access control. By centralizing policy creation and deployment, the PAN provides administrators with efficient management while enabling PSNs to focus solely on real-time enforcement. Therefore, PAN is essential for configuration management, while PSNs enforce, MnTs monitor, and Guest Nodes facilitate temporary user access.

Question 52

Which ISE feature provides secure onboarding for employee-owned devices, including certificate deployment and Wi-Fi configuration?

A) Guest Access
B) BYOD
C) Posture
D) TrustSec

Answer: B) BYOD

Explanation:

The correct answer is B) BYOD. BYOD (Bring Your Own Device) allows employees to securely onboard personal devices into the corporate network. BYOD workflows automate registration, certificate deployment, Wi-Fi profile configuration, and policy assignment, enabling employee devices to access the network without compromising security. ISE integrates BYOD with posture assessment to ensure devices meet corporate security requirements before granting full access.

A) Guest Access is incorrect because Guest Access provides temporary network access for visitors or contractors. Guest Access handles self-registration, sponsor approval, and voucher-based access but does not manage employee-owned devices or deploy certificates.

B) BYOD is correct because it provides a complete onboarding solution for personal devices. BYOD workflows allow devices to register via a self-service portal, receive certificates for secure authentication, and automatically configure Wi-Fi profiles. Additionally, BYOD can leverage posture policies to assess device compliance with antivirus, firewall, and patching requirements before granting full access. BYOD integration ensures seamless access for employees while maintaining network security.

C) Posture is incorrect because posture evaluates endpoint health and compliance but does not handle onboarding or certificate deployment. Posture results feed into authorization policies but do not manage device registration or configuration.

D) TrustSec is incorrect because TrustSec enforces identity-based access control using Security Group Tags (SGTs) and does not onboard or configure devices. TrustSec may be applied after BYOD registration to assign proper SGTs, but it is not responsible for the onboarding process.

BYOD enables organizations to support personal devices without sacrificing security. By integrating onboarding, certificate deployment, Wi-Fi provisioning, and posture assessment, BYOD ensures employee devices are compliant and securely connected. It simplifies IT operations, improves user experience, and reduces administrative overhead. BYOD handles the secure onboarding of employee-owned devices, while Guest Access, Posture, and TrustSec perform complementary functions in temporary access, compliance, and segmentation.

Question 53

Which protocol does Cisco ISE primarily use to authenticate and authorize administrators on network devices?

A) RADIUS
B) TACACS+
C) SNMP
D) HTTP

Answer: B) TACACS+

Explanation:

The correct answer is B) TACACS+. TACACS+ is used to authenticate, authorize, and account for administrative access to network devices. It provides centralized control over who can access switches, routers, and firewalls, and which commands administrators can execute. TACACS+ separates authentication, authorization, and accounting, enabling fine-grained command-level access control and detailed auditing of administrative actions. ISE integrates TACACS+ to enforce role-based access and maintain accountability for configuration changes.

A) RADIUS is incorrect because RADIUS is primarily used for endpoint network access. While it supports AAA, it does not provide granular command-level control for administrators on network devices.

B) TACACS+ is correct because it secures administrative access, allowing role-based permissions and command authorization. It ensures that administrators are accountable, with all actions logged for auditing and compliance.

C) SNMP is incorrect because SNMP is used for monitoring and device management, not for authenticating or authorizing administrative access.

D) HTTP is incorrect because HTTP is a transport protocol used for web-based portals, such as BYOD or guest self-service. It does not enforce administrator AAA.

TACACS+ is essential for secure management of network infrastructure. By integrating with ISE, administrators can define roles, restrict commands, and log actions, ensuring accountability and compliance across enterprise devices.

Question 54

Which ISE node type enforces authentication, authorization, and posture policies in real-time?

A) PAN
B) PSN
C) MnT
D) Guest Node

Answer: B) PSN

Explanation:

The correct answer is B) Policy Service Node (PSN). PSNs are responsible for real-time policy enforcement in Cisco ISE. They process RADIUS and TACACS+ requests, evaluate authorization rules, apply posture results, and communicate decisions to network devices. PSNs scale horizontally to handle large volumes of authentication requests, ensuring consistent access control across distributed deployments.

A) PAN is incorrect because it manages configuration and policy deployment. PAN does not enforce policies in real-time.

B) PSN is correct because it applies access policies dynamically, integrating input from profiling, posture, and authorization. PSNs ensure endpoints are authenticated, compliant, and assigned appropriate network privileges.

C) MnT is incorrect because MnT nodes collect logs, provide reporting, and support troubleshooting but do not enforce real-time policies.

D) Guest Node is incorrect because Guest Nodes provide self-service portals for temporary users but do not enforce network policies on corporate endpoints.

PSNs are essential for operational functionality, ensuring real-time decision-making, compliance enforcement, and dynamic access control.

Question 55

Which feature in ISE assigns Security Group Tags (SGTs) for identity-based network segmentation?

A) Posture
B) BYOD
C) TrustSec
D) Guest Access

Answer: C) TrustSec

Explanation:

The correct answer is C) TrustSec. TrustSec provides identity-based access control using Security Group Tags (SGTs) to segment the network. SGTs are assigned to users, devices, or endpoints based on role, posture, or authorization policy. Network devices enforce policies using SGTs instead of IP addresses, simplifying segmentation and improving scalability.

A) Posture is incorrect because posture evaluates endpoint compliance but does not assign SGTs. Posture results may influence TrustSec assignments but are not responsible for tagging.

B) BYOD is incorrect because BYOD handles onboarding and provisioning, not SGT assignment. BYOD devices may receive SGTs based on policies, but TrustSec performs the segmentation.

C) TrustSec is correct because it enables role-based access using SGTs and integrates with authorization policies, posture, and profiling. It ensures consistent, scalable network segmentation.

D) Guest Access is incorrect because guest access provides temporary user onboarding but does not implement identity-based segmentation.

TrustSec simplifies policy enforcement, enhances security, and reduces reliance on VLANs or IP-based ACLs.

Question 56

Which ISE feature allows the automatic identification of device types and operating systems connecting to the network?

A) Posture
B) Profiling
C) BYOD
D) Guest Access

Answer: B) Profiling

Explanation:

The correct answer is B) Profiling. Profiling in Cisco ISE is a feature that provides automatic identification and classification of devices as they connect to the network. Profiling collects information such as device type, manufacturer, operating system, and other endpoint attributes. It can gather this data from multiple sources including RADIUS requests, DHCP logs, SNMP traps, HTTP headers, and NetFlow. The information collected allows ISE to categorize devices into types such as laptops, IP phones, printers, or IoT devices. This classification is essential because it enables administrators to implement differentiated access policies, assign VLANs, or apply ACLs based on the type of device connecting to the network.

A) Posture is incorrect because posture assesses security compliance, like whether antivirus, firewall, or patches are installed, but it does not identify what type of device is connecting.

B) Profiling is correct because its primary function is identification and classification, which feeds into authorization policies for context-aware access control. For instance, unknown IoT devices can be automatically assigned limited access until they are registered.

C) BYOD is incorrect because BYOD handles onboarding employee-owned devices, not general automatic classification of all network endpoints.

D) Guest Access is incorrect because it focuses on temporary users and their access workflows, not device identification.

Profiling is essential in complex enterprise networks where multiple types of devices coexist, as it enhances visibility, supports compliance, and allows dynamic access decisions based on endpoint type and role.

Question 57

Which Cisco ISE node collects logs, provides reporting, and supports troubleshooting activities?

A) PSN
B) PAN
C) MnT
D) Guest Node

Answer: C) MnT

Explanation:

The correct answer is C) MnT. Monitoring and Troubleshooting (MnT) nodes in Cisco ISE are responsible for aggregating logs from all authentication, authorization, posture, BYOD, and guest activities across the deployment. MnT nodes provide administrators with dashboards, reports, and tools to analyze network activity and troubleshoot issues effectively. For example, if a device fails authentication or posture assessment, the MnT logs can provide detailed insight into the reason for failure, the policies applied, and the network segments affected.

A) PSN is incorrect because PSNs enforce policies in real-time but do not centralize logging or reporting across the network.

B) PAN is incorrect because PAN manages policy creation and configuration but is not responsible for collecting or analyzing operational data.

C) MnT is correct because it collects and stores logs for auditing, troubleshooting, and compliance reporting. Administrators can generate historical and real-time reports to understand trends, detect anomalies, and verify that posture, BYOD, guest access, and authorization policies are being applied correctly. MnTs also enable alerts for suspicious activity and provide visibility into device compliance, guest onboarding status, and network access patterns.

D) Guest Node is incorrect because Guest Nodes handle temporary user registration and access but do not offer centralized monitoring or reporting functionality.

MnT nodes are crucial in enterprise deployments where operational visibility, auditing, and troubleshooting are required for both security and compliance purposes, ensuring administrators have the information needed to maintain a secure and well-managed network.

Question 58

Which protocol is used by ISE to enforce endpoint network access on wired and wireless devices?

A) RADIUS
B) TACACS+
C) SNMP
D) HTTP

Answer: A) RADIUS

Explanation:

The correct answer is A) RADIUS. RADIUS (Remote Authentication Dial-In User Service) is the primary protocol used by Cisco ISE to authenticate, authorize, and account for endpoints connecting to wired and wireless networks. When a device attempts to connect, the network access device (switch, wireless controller, or VPN concentrator) communicates with the ISE PSN using RADIUS to verify the credentials and check policies. RADIUS allows ISE to apply authorization rules, assign VLANs, apply downloadable ACLs, and enforce posture results dynamically.

A) RADIUS is correct because it supports the full AAA framework and integrates seamlessly with Cisco ISE policies for real-time access enforcement. For example, a compliant laptop might receive full network access, while a guest device might be redirected to a captive portal, all via RADIUS.

B) TACACS+ is incorrect because it is primarily used for administrative access to network devices rather than endpoint authentication.

C) SNMP is incorrect because SNMP is a monitoring protocol, used to collect network device statistics, not to enforce network access.

D) HTTP is incorrect because HTTP is used for web-based portals such as BYOD or guest self-service registration, but it is not used for real-time network access enforcement.

RADIUS is critical to the dynamic enforcement of ISE policies. It ensures secure access by validating credentials, evaluating authorization policies, and applying network restrictions as necessary. Its ability to provide accounting logs also supports auditing and compliance requirements across enterprise networks.

Question 59

Which ISE node type is responsible for creating and distributing configuration and policies?

A) PSN
B) PAN
C) MnT
D) Guest Node

Answer: B) PAN

Explanation:

The correct answer is B) PAN. The Policy Administration Node (PAN) in Cisco ISE is responsible for central configuration management. Administrators define authentication rules, authorization policies, posture assessments, BYOD workflows, guest access policies, and TrustSec configurations on the PAN. Once policies are defined, the PAN distributes them to Policy Service Nodes (PSNs) for real-time enforcement. This centralized administration ensures consistency across the deployment, simplifies management, and reduces the risk of misconfigurations.

A) PSN is incorrect because PSNs enforce policies in real-time but do not handle policy creation or distribution.

B) PAN is correct because it centralizes configuration and administration. PAN nodes are the authoritative source for all policy decisions, ensuring that the enforcement nodes receive up-to-date configurations and that network access is applied consistently.

C) MnT is incorrect because MnTs focus on collecting logs, monitoring events, and providing troubleshooting and reporting capabilities.

D) Guest Node is incorrect because Guest Nodes provide self-service portals for temporary users but do not create or distribute enterprise-wide policies.

By centralizing configuration on the PAN, organizations can maintain uniform policy enforcement, simplify administrative tasks, and integrate with external identity stores, ensuring the deployment scales efficiently without introducing inconsistencies.

Question 60

Which Cisco ISE feature allows temporary users to access the network through self-registration or sponsor approval?

A) BYOD
B) Posture
C) Guest Access
D) TrustSec

Answer: C) Guest Access

Explanation:

The correct answer is C) Guest Access. Guest Access in Cisco ISE provides a secure method for temporary users, such as contractors or visitors, to access the network. It offers self-registration portals where users can request temporary credentials or sponsor approval workflows where an employee approves guest access. Administrators can apply time-based access restrictions, VLAN assignments, and ACLs to isolate guest traffic from corporate resources. Guest Access also integrates with reporting and monitoring to maintain security and compliance visibility.

A) BYOD is incorrect because BYOD handles onboarding of employee-owned devices, not temporary users.

B) Posture is incorrect because posture evaluates endpoint compliance but does not manage temporary user registration or access workflows.

C) Guest Access is correct because it manages the full lifecycle of temporary network access, from registration to expiration. It allows administrators to define customizable portals, sponsor workflows, and policy-based access enforcement for guests.

D) TrustSec is incorrect because TrustSec is used for network segmentation via Security Group Tags (SGTs), not for guest registration or temporary access.

Guest Access ensures secure, controlled, and auditable connectivity for temporary users while maintaining corporate network security. It allows enterprises to enforce policy-based isolation, time-limited access, and seamless integration with other ISE components, ensuring guest access does not compromise the security of production networks.
