Question 81

An organization wants to enforce device health checks before granting full access to the corporate network. Users must be redirected to a remediation page when their endpoints fail security requirements. Which Cisco ISE feature performs this function?

A) Posture Assessment
B) Device Profiling
C) Security Group Tags
D) Guest Access

Answer: A) Posture Assessment

Explanation:

The correct answer is A) because posture assessment is the Cisco ISE feature explicitly designed to check endpoint compliance before the device is granted network access. Posture assessment examines key security attributes such as antivirus status, running services, disk encryption, firewall settings, and OS patch levels. When an endpoint fails any of these checks, ISE can dynamically redirect that user to a remediation portal, where instructions and update procedures are provided. The ability to validate device health before granting full network access is central to zero-trust network security, and posture is the mechanism used to accomplish this.

B) device profiling is a powerful ISE capability, but its purpose is to identify the device type based on DHCP, HTTP user-agent strings, SNMP data, and various network signatures. Profiling does not evaluate device health or security state—therefore it cannot ensure that a device is running antivirus software or that patches are updated. Profiling helps determine what the device “is,” while posture determines whether the device is “secure.”

C) Security Group Tags (SGTs) are part of Cisco TrustSec and are used for access segmentation. SGTs attach security context to a user or device so that access control lists can dynamically control resource access. Although SGTs are useful for network segmentation and enforcing policy based on identity, they do not check device health, cannot remediate endpoints, and do not provide user redirection to update security components.

D) Guest Access is designed for temporary users such as visitors, contractors, or third-party partners. It handles workflows such as web authentication, sponsor approval, and guest credentials. Guest access does not evaluate endpoint health, so although guests may be isolated into a dedicated VLAN or network segment, guest services alone cannot perform posture validation.

Posture works by using the Cisco AnyConnect Agent (or the ISE posture module within AnyConnect). The agent communicates with Cisco ISE over the posture protocol and reports device health attributes. If the device complies with the policy, ISE authorizes the endpoint into the appropriate access level. If the device fails, a CoA (Change of Authorization) occurs, instructing the switch or wireless controller to place the user in a remediation VLAN or redirect them to a remediation web portal. Administrators can define mandatory requirements (like antivirus must be running) and optional requirements (like password complexity). Posture also supports periodic reevaluation to ensure devices remain compliant as long as they stay connected.

This capability is essential in environments with strict security standards, remote workforces, or regulatory compliance needs (such as PCI or HIPAA). Without posture, infected or unpatched devices could obtain unrestricted access, potentially spreading malware or compromising sensitive corporate data. By enforcing posture before granting access, Cisco ISE ensures that devices are secure, compliant, and properly maintained—making A) the only correct choice in this scenario.

Question 82

A company wants to provide network access for personal devices, but users must complete a self-service onboarding process with certificate provisioning. Which Cisco ISE feature supports this capability?

A) BYOD
B) TACACS+
C) Guest Flow
D) pxGrid

Answer: A) BYOD

Explanation:

The correct answer is A) because Cisco ISE BYOD (Bring Your Own Device) is the only feature designed to onboard personal devices through a self-service workflow that includes certificate provisioning. BYOD allows employees to register their personal laptops, tablets, and smartphones, ensuring secure authentication while reducing help-desk involvement. During onboarding, ISE can automatically install certificates, configure Wi-Fi profiles, and apply device-specific network access policies.

B) TACACS+ is a protocol used for administrative device access control. It allows centralized authentication of administrators who log into routers, switches, and firewalls—but TACACS+ is not used for endpoint onboarding, certificate delivery, or user-managed device registration. It has no capability for onboarding iPhones, Android devices, laptops, or tablets.

C) Guest Flow enables temporary access for visitors using web authentication and credentials that may be created through a sponsor portal. However, while guest access can assign limited network access to unmanaged devices, it does not provide certificate provisioning or persistent user-based onboarding processes. Guest networks are intentionally open and temporary, whereas BYOD involves permanent enrollment into the corporate identity structure.

D) pxGrid is an ISE integration framework used to share context information with external systems such as firewalls, SIEM platforms, and threat intelligence tools. pxGrid provides rich visibility but does not onboard devices.

BYOD is specifically developed for the scenario described. It provides workflows such as device registration, certificate installation, profile deployment, and policy-based authorization. ISE identifies devices through profiling, validates user identity, generates a certificate via the Certificate Authority (CA), and pushes network settings. This allows personal devices to authenticate using 802.1X—greatly improving security when compared to shared passwords or open networks.

The onboarding process typically starts when a user connects to a secure SSID or wired port that triggers redirection to the BYOD portal. Users authenticate using corporate credentials. ISE then provides downloadable configuration helpers or directs the user to a device management service (such as Apple MDM or Android configuration tools). Once certificates and profiles are installed, the device reconnects to the secure network using EAP-TLS, ensuring strong mutual authentication.

BYOD also tightly integrates with posture, profiling, and authorization mapping so that personal devices receive the right level of access without compromising corporate security. This makes A) the answer that matches the scenario perfectly.

Question 83

Administrators need to reduce the number of authorization policy entries by grouping users and devices into logical segments, making access control easier to manage across the network. Which feature should be used?

A) Security Group Tags
B) RADIUS VLAN Assignment
C) Web Authentication
D) Local ISE Users

Answer: A) Security Group Tags

Explanation:

The correct answer is A) because Security Group Tags (SGTs), part of Cisco TrustSec, provide scalable segmentation by assigning a security context to users or devices. This allows administrators to reduce the number of authorization rules by grouping identities into security groups instead of building long lists of VLANs, ACLs, or user identities. SGTs enable policy enforcement through Security Group Access Control Lists (SGACLs), which dramatically simplify access management in large environments.

B) RADIUS VLAN assignment. VLANs are a traditional method of segmentation but quickly become unmanageable in large networks. VLAN sprawl happens when administrators create separate VLANs for every user group, device type, or location. This does not scale well, and it does not reduce complexity. VLANs also do not inherently express user identity, so they cannot provide the dynamic segmentation required by modern zero-trust architectures.

C) Web Authentication is used mainly for guest access or certain BYOD pre-onboarding scenarios. WebAuth does not create logical segments or simplify authorization policies. Its main purpose is authenticating users through a captive portal—not creating scalable identity-based segmentation.

D) Local ISE Users refers to storing user accounts directly on ISE for authentication. While useful for small environments or guest sponsors, local users do not help reduce policy entries. They also provide no dynamic grouping or segmentation capabilities.

SGTs solve the problem by allowing administrators to tag endpoints based on user identity, device type, or posture compliance. These tags travel with network traffic (or are enforced at hop boundaries), allowing switches, firewalls, and routers to apply SGACLs. Instead of building hundreds of rules, administrators create one rule per security group—massively reducing complexity.

SGTs also support scalable group-based policy enforcement across multiple network devices, including switches, wireless controllers, and firewalls. They are essential in software-defined access (SD-Access) environments, where group-based policies define how traffic flows between segments.

SGTs also support dynamic assignment through ISE authorization policies. Once a user authenticates, ISE instructs the switch to apply a specific SGT. This identity-based segmentation is stronger, more flexible, and more scalable compared to VLAN-based segmentation. All of these advantages make A) the only valid answer.

Question 84

A security engineer wants to integrate Cisco ISE with a firewall so that user and device context can dynamically inform firewall policies. Which feature must be used?

A) pxGrid
B) CoA
C) MACsec
D) EAP-TLS

Answer: A) pxGrid

Explanation:

The correct answer is A) because pxGrid is the Cisco ISE framework that enables context exchange between ISE and third-party platforms including firewalls, SIEMs, and threat intelligence systems. pxGrid shares attributes such as user identity, device type, posture status, profiling information, and security group assignments. Firewalls can then dynamically adjust security rules based on this real-time context.

B) CoA (Change of Authorization) allows ISE to modify a user’s session authorization level dynamically—for example, moving a non-compliant device into a quarantine VLAN. However, CoA does not exchange context with firewalls. It is strictly an enforcement mechanism between ISE and the network access device, not a context-sharing mechanism with security appliances.

C) MACsec provides Layer 2 encryption for securing traffic between endpoints and network devices. While critical for data confidentiality, MACsec does not exchange identity or device context with firewalls. Its purpose is traffic encryption, not integration.

D) EAP-TLS is a certificate-based authentication method used in 802.1X wireless and wired authentication. It provides strong mutual authentication but does not send identity information directly to firewalls.

pxGrid solves the integration challenge by enabling security platforms to subscribe to identity and posture events generated by Cisco ISE. For example, a firewall can receive notifications that a device has become non-compliant. The firewall can then block traffic, isolate the device, or apply more restrictive rules automatically.

Additionally, pxGrid supports Trustsec SGT propagation into firewalls, enabling group-based policy enforcement. Firewalls can enforce SGACLs based on SGTs, ensuring consistent segmentation across the network.

For these reasons, A) is the only correct choice.

Question 85

A network team wants to authenticate administrators who log into switches and firewalls. They also need command-level authorization and detailed accounting logs of all admin actions. Which Cisco ISE protocol should be used?

A) RADIUS
B) TACACS+
C) EAP-FAST
D) SAML

Answer: B) TACACS+

Explanation:

Examining the incorrect options clarifies why TACACS+ is the only valid answer. A) RADIUS is typically used for network access authentication (such as 802.1X wireless or VPN authentication). While it supports authentication and accounting, RADIUS cannot provide granular command authorization for device administration. It also mixes authentication and authorization in the same packet and does not encrypt the entire payload, making it less suitable for administrative security.

The correct answer is B) because TACACS+ is the protocol designed specifically for device administration, providing authentication, authorization, and accounting (AAA) for engineers and administrators accessing network devices. TACACS+ allows command-by-command authorization, meaning administrators can be restricted to specific commands based on their assigned privilege levels. It also logs every command performed, providing a detailed audit trail which is essential for compliance, troubleshooting, and security investigations.

C) EAP-FAST is an 802.1X authentication method used for user and device authentication. It is not applicable for managing administrator logins to routers or switches. EAP methods run at the user access layer—not administrative access to infrastructure devices.

D) SAML is an identity federation protocol used mainly for web-based applications and SSO. It cannot authenticate administrators logging into CLI sessions of switches or firewalls.

TACACS+ centralizes administrator control, enforcing policies such as: who can log in, what commands they can execute, what privilege levels they have, and what devices they can access. When integrated with Cisco ISE, TACACS+ offers real-time monitoring and full AAA capabilities.

Because the requirement specifically mentions command-level authorization and accounting, only B) TACACS+ fully satisfies the scenario.

Question 86

Which ISE feature allows administrators to define network access policies based on device posture, user identity, and location?

A) Authorization Policy
B) Profiling
C) BYOD
D) Guest Access

Answer: A) Authorization Policy

Explanation:

The correct answer is A) Authorization Policy. Authorization policies in Cisco ISE are the mechanism through which access decisions are made after a device or user has been authenticated. These policies evaluate multiple contextual parameters such as user identity, device posture, profiling information, and even location to determine the appropriate level of network access. By leveraging these policies, administrators can enforce granular control and dynamically adjust network access in real time.

A) Authorization Policy is correct because it provides centralized control to enforce network security policies that incorporate inputs from authentication, posture assessment, and device profiling. For example, a corporate laptop with full compliance might be granted full access to internal resources, whereas a guest device might be redirected to a restricted VLAN or a remediation portal. Authorization policies also support Time-of-Day or Location-based rules, which can enforce access limitations based on the user’s physical or logical location, adding another layer of security.

B) Profiling is incorrect because profiling is used primarily to identify device types and gather information such as operating system, manufacturer, and MAC address. Profiling does not enforce access control but feeds device information into authorization policies for decision-making.

C) BYOD is incorrect because BYOD focuses on onboarding employee-owned devices and deploying certificates for secure access, but it does not make contextual access decisions on its own. BYOD relies on authorization policies to determine the level of access granted to a registered device.

D) Guest Access is incorrect because it provides temporary network access to visitors or contractors. While guest access workflows rely on authorization policies for enforcement, the guest feature itself does not provide multi-criteria decision-making based on posture, user identity, and location.

Authorization policies are critical in enterprise deployments because they allow administrators to implement dynamic and adaptive security. By combining information from authentication, posture assessment, device profiling, and location, these policies help ensure that only authorized users and compliant devices gain appropriate access. This not only reduces the risk of security breaches but also allows organizations to maintain operational efficiency while enforcing regulatory compliance and minimizing administrative overhead.

Question 87

Which Cisco ISE protocol is used to enforce administrator access to network devices with detailed command-level authorization?

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

Answer: B) TACACS+

Explanation:

The correct answer is B) TACACS+. TACACS+ (Terminal Access Controller Access-Control System Plus) is a protocol that provides AAA (Authentication, Authorization, and Accounting) for administrative access to network devices. Unlike RADIUS, which is used primarily for endpoint authentication, TACACS+ separates authentication, authorization, and accounting functions, allowing administrators to enforce granular, command-level permissions for users accessing routers, switches, or firewalls.

A) RADIUS is incorrect because RADIUS is used for authenticating network endpoints and granting access based on user identity and device compliance. While RADIUS can be used for some administrative authentication, it does not support detailed command-level authorization.

B) TACACS+ is correct because it allows administrators to define role-based access controls that restrict users to specific commands or sets of operations on network devices. For example, junior engineers can be limited to monitoring commands, whereas senior engineers can make configuration changes. TACACS+ also logs all administrative commands, providing a full audit trail, which is essential for compliance and troubleshooting.

C) HTTP is incorrect because HTTP is used for web-based portals such as BYOD or guest self-service registration, and does not provide real-time network device authentication or authorization.

D) SNMP is incorrect because SNMP is primarily a monitoring protocol used to collect network device statistics. SNMP does not provide authentication or enforce access policies.

TACACS+ integration with Cisco ISE is critical for operational security and accountability. By combining centralized authentication with command-level authorization and comprehensive logging, TACACS+ ensures that only authorized administrators can perform specific actions on network devices. This separation of privileges enhances security by minimizing the risk of accidental or malicious configuration changes. It also provides detailed auditing capabilities, allowing organizations to track changes, meet regulatory requirements, and troubleshoot issues efficiently. In large enterprise deployments, TACACS+ simplifies the management of administrative roles across multiple devices while maintaining strict security standards.

Question 88

Which ISE node collects logs, generates reports, and provides monitoring for authentication, authorization, posture, and BYOD workflows?

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 operational activities, including authentication, authorization, posture, BYOD onboarding, and guest access. MnT nodes provide administrators with centralized visibility into network operations through dashboards, reports, and troubleshooting tools. This visibility is crucial for auditing, compliance, and incident response.

A) PSN is incorrect because Policy Service Nodes process authentication and authorization requests in real time but do not provide comprehensive monitoring or centralized reporting. PSNs send logs to MnT nodes for analysis.

B) PAN is incorrect because Policy Administration Nodes manage configuration and policy distribution, but they do not perform logging or generate reports.

C) MnT is correct because it provides full operational visibility. Administrators can track authentication failures, monitor posture compliance, analyze BYOD enrollment statistics, and audit guest access activities. MnT nodes also generate historical and real-time reports to support troubleshooting and regulatory compliance. By centralizing log collection, MnT nodes allow organizations to detect trends, identify misconfigurations, and investigate security incidents efficiently.

D) Guest Node is incorrect because Guest Nodes provide temporary access portals and sponsor approval workflows but do not aggregate network-wide logs or provide monitoring for enterprise-wide operations.

MnT nodes are essential in enterprise environments to maintain situational awareness. They ensure that administrators can quickly identify network issues, verify that policies are applied correctly, and generate reports for regulatory compliance. By integrating with PSNs, PANs, and Guest Nodes, MnT nodes enable a complete operational view, making them a cornerstone of Cisco ISE deployments for security, monitoring, and troubleshooting.

Question 89

Which ISE feature evaluates the security compliance of endpoints and redirects non-compliant devices to remediation portals?

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

Answer: A) Posture

Explanation:

The correct answer is A) Posture. Posture in Cisco ISE assesses endpoint security compliance before granting network access. This includes verifying antivirus presence, firewall status, operating system updates, and other security requirements. If an endpoint fails the posture assessment, ISE can restrict access, place the device in a remediation VLAN, or redirect the user to a remediation portal where they can update their software or configuration to achieve compliance.

A) Posture is correct because it evaluates compliance dynamically and enforces access restrictions based on endpoint health. The assessment can be agent-based, where software installed on the device communicates with ISE, or agentless, using network-based methods. Posture results feed directly into authorization policies, determining what level of network access is granted to the endpoint.

B) BYOD is incorrect because BYOD focuses on onboarding personal devices, deploying certificates, and configuring Wi-Fi. While BYOD may integrate posture to check compliance during onboarding, it is not responsible for evaluating ongoing endpoint health.

C) TrustSec is incorrect because TrustSec enforces identity-based segmentation using Security Group Tags (SGTs), but it does not assess device compliance or provide remediation workflows.

D) Guest Access is incorrect because it provides temporary access for visitors or contractors and does not perform security compliance evaluations for endpoints.

Posture is a critical component of Cisco ISE because it helps prevent compromised or non-compliant devices from accessing corporate resources. By integrating posture assessment with authorization policies, organizations can enforce dynamic, context-aware access controls that protect sensitive data. Posture also supports regulatory compliance by ensuring that endpoints meet minimum security standards before accessing the network. The combination of posture assessment and remediation workflows ensures that devices are continuously evaluated and brought into compliance, reducing the risk of security breaches while maintaining network availability and operational efficiency.

Question 90

Which ISE component manages centralized configuration, policy creation, and distribution across the deployment?

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 serves as the centralized management point for configuration and policy creation. Administrators define authentication, authorization, posture, BYOD, guest, and TrustSec policies on the PAN. These policies are then distributed to Policy Service Nodes (PSNs) for real-time enforcement. The PAN ensures consistency across all nodes in the deployment, which is critical for large, multi-site networks.

A) PSN is incorrect because PSNs enforce policies in real time but do not manage policy creation or distribution. They rely on PANs to receive configuration updates.

B) PAN is correct because it centralizes all administrative functions. By managing policies centrally, the PAN reduces administrative complexity, ensures consistency across the deployment, and minimizes the risk of misconfigurations. PAN also manages node groups, system certificates, and integration with external identity stores like Active Directory. Centralized configuration through the PAN allows administrators to replicate policies across sites, scale the deployment, and maintain high availability.

C) MnT is incorrect because Monitoring and Troubleshooting nodes aggregate logs and provide visibility but do not manage configuration or policies.

D) Guest Node is incorrect because Guest Nodes handle temporary user access and self-service registration but are not responsible for managing enterprise-wide policies.

The PAN is critical for enterprise deployments as it separates administrative functions from enforcement, allowing scalable, consistent, and secure network access management. Without a PAN, administrators would need to manually configure each PSN, increasing operational overhead and the risk of errors. PAN centralization ensures that updates are consistently applied, authorization policies are accurately enforced, and the entire ISE deployment remains synchronized and compliant.

Question 91

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

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

Answer: A) BYOD

Explanation:

The correct answer is A) BYOD. Cisco ISE BYOD (Bring Your Own Device) is designed to enable secure onboarding of personal devices such as laptops, tablets, and smartphones. BYOD automates several critical tasks during the onboarding process. It can deploy digital certificates for secure 802.1X authentication, configure Wi-Fi profiles, and enforce security policies tailored to each device. This process ensures that employee-owned devices can safely connect to the corporate network without introducing vulnerabilities or requiring extensive manual IT intervention.

A) BYOD is correct because it integrates onboarding, authentication, and configuration workflows. The BYOD portal guides employees through self-registration steps where they provide credentials, and ISE validates identity using external identity stores like Active Directory. Once authenticated, ISE automatically deploys certificates and network configuration, such as SSIDs and security settings. In addition, BYOD can enforce posture assessments to ensure that the device meets organizational security requirements, such as running updated antivirus software or firewall protection. This combination of onboarding and compliance ensures that personal devices do not compromise network security while providing seamless user experience.

B) Guest Access is incorrect because guest access focuses on temporary network connectivity for visitors or contractors. While it provides self-service portals, it does not handle employee-owned device onboarding, certificate deployment, or Wi-Fi configuration.

C) TrustSec is incorrect because TrustSec enforces role-based access using Security Group Tags (SGTs), but it does not facilitate device onboarding or configuration. It is primarily a network segmentation technology, not an onboarding workflow.

D) Posture is incorrect because posture evaluates the security compliance of endpoints but does not handle onboarding, certificate deployment, or network configuration. Posture works in conjunction with BYOD to determine access eligibility after onboarding.

BYOD is crucial in modern enterprises where employees bring multiple devices to work. It allows organizations to maintain a balance between security and productivity, ensuring that personal devices comply with security standards while avoiding cumbersome manual configuration. By combining BYOD with posture and authorization policies, ISE enables dynamic access control based on device type, security posture, and user role. BYOD reduces administrative overhead, enhances compliance, and provides a streamlined user experience, making it a foundational feature for enterprise mobility and secure network access.

Question 92

Which ISE protocol is primarily used to authenticate wired and wireless endpoints and enforce network access policies?

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

Answer: A) RADIUS

Explanation:

The correct answer is A) RADIUS. Remote Authentication Dial-In User Service (RADIUS) is the primary protocol used by Cisco ISE for endpoint authentication and authorization on wired, wireless, and VPN networks. When a device or user attempts to connect, network access devices such as switches or wireless controllers forward a RADIUS request to ISE. ISE evaluates the credentials, applies authorization policies, and grants or denies access based on user role, device type, posture compliance, and other contextual attributes. RADIUS also provides accounting capabilities to log session information for auditing and compliance purposes.

A) RADIUS is correct because it is widely supported by network access devices and integrates with ISE to enforce access dynamically. Authorization policies determine VLAN assignment, ACLs, and TrustSec Security Group Tag (SGT) assignments based on the endpoint’s profile, user identity, and posture. For instance, a corporate laptop may be granted full internal access, whereas a non-compliant device may be redirected to a remediation VLAN. RADIUS allows for consistent enforcement across wired and wireless networks, making it a cornerstone of secure network access control.

B) TACACS+ is incorrect because TACACS+ is intended for administrative access to network devices. While it provides detailed command-level authorization for network administrators, it is not designed for endpoint authentication or enforcing general network access.

C) HTTP is incorrect because HTTP is used for web-based portals, such as BYOD onboarding or guest self-registration. It does not enforce network access in real time.

D) SNMP is incorrect because SNMP is a monitoring protocol used to collect device statistics and health metrics. It does not provide authentication or authorization for endpoints.

RADIUS is essential for implementing secure, scalable network access. By integrating with ISE, RADIUS enables dynamic access control that adapts to the context of the user and device, including identity, compliance status, and device type. It ensures that only authorized endpoints can access appropriate resources while providing detailed accounting logs for auditing, reporting, and compliance. RADIUS remains the standard protocol for enterprise-grade authentication and access control in Cisco ISE deployments.

Question 93

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

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

Answer: B) PSN

Explanation:

The correct answer is B) PSN. Policy Service Nodes (PSNs) in Cisco ISE are responsible for processing authentication, authorization, and posture requests in real time. When a device or user connects to the network, the network access device sends an authentication request to a PSN. The PSN evaluates the request against configured authorization policies, checks device compliance via posture assessment, incorporates profiling information, and enforces access accordingly. PSNs ensure that access decisions are applied consistently across the network, providing real-time control and enforcement.

A) PAN is incorrect because the Policy Administration Node manages policy creation and configuration distribution but does not enforce policies in real time. PSNs rely on the PAN to receive updated policies.

B) PSN is correct because it handles operational enforcement, including RADIUS and TACACS+ requests, posture evaluation, and dynamic policy application. PSNs can dynamically assign VLANs, ACLs, and TrustSec Security Group Tags (SGTs) based on the authorization outcome. PSNs are horizontally scalable, allowing high-volume deployments and redundancy, ensuring consistent network access enforcement even in large environments.

C) MnT is incorrect because Monitoring and Troubleshooting nodes provide logging, reporting, and visibility into network events but do not perform policy enforcement.

D) Guest Node is incorrect because Guest Nodes provide self-service registration portals and sponsor approval workflows, but they do not process enterprise-wide authentication requests for real-time network access.

PSNs are critical for maintaining secure and compliant network access. By enforcing policies in real time, PSNs ensure that only authorized users and compliant devices receive appropriate access, reducing the risk of security breaches. The separation of administrative and enforcement functions allows PSNs to scale independently of PANs and MnT nodes, providing high availability and fault tolerance. PSNs work in tandem with PANs, MnTs, and Guest Nodes to form a comprehensive Cisco ISE deployment that supports dynamic, context-aware, and role-based network access control.

Question 94

Which ISE feature enforces identity-based network segmentation using Security Group Tags (SGTs)?

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

Answer: A) TrustSec

Explanation:

The correct answer is A) TrustSec. Cisco TrustSec is a network segmentation technology that enforces access policies based on Security Group Tags (SGTs). Instead of relying on IP addresses or VLANs, TrustSec uses identity-based policies to dynamically assign SGTs to users, devices, and endpoints. Network devices such as switches, routers, and firewalls enforce policies based on SGTs, allowing granular and context-aware access control.

A) TrustSec is correct because it provides identity-based segmentation that simplifies network security management. For example, finance department devices may receive an SGT allowing access to accounting servers, while guest devices receive a different SGT restricting them to internet-only access. TrustSec integrates with authorization policies in ISE to dynamically assign SGTs based on user role, device type, and posture compliance. This approach reduces the complexity of traditional ACLs and VLANs, increases security, and allows for scalable, centralized policy enforcement.

B) Posture is incorrect because posture evaluates endpoint compliance but does not enforce network segmentation. It can feed posture information into TrustSec policies but does not assign SGTs by itself.

C) BYOD is incorrect because BYOD focuses on onboarding employee-owned devices, certificate deployment, and Wi-Fi configuration, not identity-based segmentation.

D) Guest Access is incorrect because guest access manages temporary users and self-service portals, but does not assign SGTs or enforce identity-based segmentation.

TrustSec is critical in modern enterprise networks where dynamic access control is required for diverse endpoints, including BYOD, IoT, and guest devices. By combining SGTs with authorization policies, TrustSec provides scalable, centralized, and context-aware segmentation that enhances security while reducing administrative complexity. This approach allows organizations to enforce least-privilege access consistently and prevent unauthorized communication across network segments.

Question 95

Which ISE protocol allows administrators to audit command execution and enforce role-based access on network devices?

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

Answer: B) TACACS+

Explanation:

The correct answer is B) TACACS+. TACACS+ provides centralized authentication, authorization, and accounting (AAA) for administrative access to network devices. It separates authentication, authorization, and accounting functions, allowing administrators to control which commands users can execute. TACACS+ also logs all executed commands, providing a detailed audit trail critical for compliance and operational security.

A) RADIUS is incorrect because RADIUS authenticates endpoints for network access but does not provide command-level authorization for administrators.

B) TACACS+ is correct because it allows administrators to define roles that limit commands based on user responsibilities. For example, junior engineers may have read-only access, while senior engineers may execute configuration commands. TACACS+ logs all activity for auditing purposes, enabling accountability and compliance with regulatory standards.

C) HTTP is incorrect because HTTP is used for web-based portals, such as BYOD and guest registration, and does not enforce command-level access.

D) SNMP is incorrect because SNMP is a monitoring protocol and cannot provide authentication, authorization, or auditing of command execution.

TACACS+ ensures that administrative access is secure, auditable, and compliant. By integrating with ISE, organizations can enforce consistent policies across all devices, maintain role-based access controls, and log activities for operational monitoring. This is essential for maintaining network integrity and preventing unauthorized configuration changes in large-scale enterprise environments.

Question 96

Which ISE component provides centralized policy creation and distributes policies to enforcement nodes?

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

Answer: B) PAN

Explanation:

The correct answer is B) PAN. The Policy Administration Node (PAN) is the centralized management component of Cisco ISE responsible for creating, modifying, and distributing policies. Administrators define authentication, authorization, posture, BYOD, and guest policies on the PAN. Once created, these policies are replicated to Policy Service Nodes (PSNs) for real-time enforcement across the network.

A) PSN is incorrect because PSNs enforce policies but rely on the PAN to receive updated configurations.

B) PAN is correct because it centralizes all administrative functions and ensures consistency across the deployment. This eliminates the need to configure policies individually on each node and helps maintain uniform security policies.

C) MnT is incorrect because Monitoring and Troubleshooting nodes collect logs and provide reporting but do not manage policies.

D) Guest Node is incorrect because Guest Nodes provide self-service portals for temporary users but are not responsible for global policy management.

By using the PAN, organizations can manage large-scale ISE deployments efficiently, maintain policy consistency, and reduce administrative errors, ensuring a secure and well-governed network.

Question 97

Which ISE feature ensures endpoints meet security requirements before accessing the network and can redirect non-compliant devices to remediation?

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

Answer: A) Posture

Explanation:

The correct answer is A) Posture. Cisco ISE Posture evaluates the security status of devices attempting to connect to the network. It checks endpoints for antivirus, firewall, OS patch levels, and other compliance metrics. If the device fails the posture assessment, ISE can restrict network access or redirect the user to a remediation portal for corrective actions.

A) Posture is correct because it directly enforces compliance-based access control. Posture results are integrated with authorization policies, allowing dynamic decisions based on the health of the device.

B) BYOD is incorrect because BYOD focuses on onboarding personal devices but does not evaluate compliance.

C) TrustSec is incorrect because it enforces segmentation using Security Group Tags (SGTs) rather than assessing device compliance.

D) Guest Access is incorrect because it manages temporary user access, not device security compliance.

Posture ensures that only compliant devices can access sensitive resources, reducing the risk of breaches while maintaining network security.

Question 98

Which ISE protocol allows network devices to authenticate endpoints and enforce access policies in real-time?

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

Answer: A) RADIUS

Explanation:

The correct answer is A) RADIUS. RADIUS is the protocol used by Cisco ISE for authenticating and authorizing wired, wireless, and VPN endpoints. When a device connects, network access devices send a RADIUS request to ISE, which evaluates the credentials, applies authorization policies, and grants or denies access.

A) RADIUS is correct because it supports real-time access enforcement, VLAN assignment, ACL application, and integration with posture and profiling data.

B) TACACS+ is incorrect because it is used for administrative access to network devices, not general endpoint authentication.

C) SNMP is incorrect because it is a monitoring protocol, not an authentication or authorization protocol.

D) HTTP is incorrect because it provides web-based portals like BYOD or guest registration but does not enforce real-time network access.

RADIUS is essential for secure, scalable access control and is a core protocol in ISE deployments to ensure proper enforcement of policies.

Question 99

Which ISE feature provides temporary network access for visitors with self-registration and sponsor approval workflows?

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

Answer: A) Guest Access

Explanation:

The correct answer is A) Guest Access. Cisco ISE Guest Access allows visitors, contractors, or temporary employees to gain network access securely. Guests can register themselves via a self-service portal, or a sponsor can approve their access. Once approved, credentials are issued, and access is restricted according to policies, including VLAN assignment and ACLs.

A) Guest Access is correct because it manages the entire lifecycle of temporary users, ensuring secure, auditable, and controlled access.

B) BYOD is incorrect because BYOD focuses on employee-owned devices rather than temporary visitors.

C) TrustSec is incorrect because TrustSec enforces role-based segmentation using SGTs but does not manage guest workflows.

D) Posture is incorrect because posture evaluates endpoint compliance rather than managing temporary access.

Guest Access ensures secure, temporary connectivity while maintaining network segmentation, security, and audit compliance, reducing administrative effort for temporary users.

Question 100

Which ISE feature enforces identity-based network segmentation using Security Group Tags (SGTs)?

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

Answer: A) TrustSec

Explanation:
The correct answer is A) TrustSec. Cisco TrustSec enforces network segmentation by assigning Security Group Tags (SGTs) to users, devices, or endpoints. These tags are used by network devices to enforce access policies dynamically, replacing traditional VLANs or ACLs with identity-based enforcement.

A) TrustSec is correct because it allows administrators to implement fine-grained access controls based on user role, device type, and other contextual attributes. TrustSec ensures that sensitive resources are accessible only by authorized users and devices, even in complex networks.

B) Posture is incorrect because posture evaluates device compliance but does not perform segmentation.

C) BYOD is incorrect because BYOD focuses on onboarding employee devices, not identity-based segmentation.

D) Guest Access is incorrect because guest access manages temporary user access, not SGT enforcement.

TrustSec provides scalable, centralized network segmentation, enhancing security by allowing context-aware access decisions, reducing complexity compared to traditional VLAN and ACL implementations.
