Question 141

Which ISE feature enables administrators to create temporary network access accounts for contractors or visitors with predefined expiration policies?

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

Answer: A) Guest Access

Explanation:

The correct answer is A) Guest Access. Cisco ISE Guest Access is designed to provide controlled, temporary network access for external users such as contractors, vendors, or visitors. It enables administrators to create accounts with predefined expiration dates, ensuring that temporary users do not retain access beyond their required period. Guest Access provides self-registration portals where visitors can register themselves or sponsor-based workflows where internal users approve guest accounts.

A) Guest Access is correct because it manages the lifecycle of temporary users, from account creation to expiration. Administrators can define policies specifying how long accounts are valid, which network resources are accessible, and whether users require sponsor approval. For example, a contractor may receive access to specific VLANs with internet-only connectivity for a period of 7 days, after which the account automatically expires. Guest Access integrates with authorization policies in ISE, allowing dynamic assignment of VLANs, ACLs, and Security Group Tags (SGTs) to control access. Reporting and auditing are also integral to Guest Access, providing visibility into guest activity, registration patterns, and compliance.

B) BYOD is incorrect because BYOD focuses on onboarding employee-owned devices, certificate deployment, and secure access, rather than temporary accounts for external users.

C) Posture is incorrect because posture evaluates the security compliance of devices, ensuring endpoints meet organizational standards before granting access. It does not manage temporary user accounts.

D) TrustSec is incorrect because TrustSec is concerned with identity-based segmentation and assigning SGTs for network access, not managing temporary accounts.

Guest Access is critical in enterprise networks where temporary or external users frequently connect. It reduces administrative overhead by automating account creation and expiration, ensures secure and controlled access to network resources, and supports regulatory compliance through logging and reporting. By integrating with ISE policies, Guest Access provides secure, role-based access while maintaining visibility and auditability. It also helps prevent unauthorized access by automatically disabling expired accounts and enforcing sponsor approval workflows for accountability.

Question 142

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

Answer: A) TACACS+

Explanation:

The correct answer is A) TACACS+. TACACS+ is a protocol used for centralized authentication, authorization, and accounting (AAA) specifically for administrative users on network devices. Unlike RADIUS, which is designed for endpoint network access, TACACS+ enables command-level authorization, allowing fine-grained control over which commands an administrator can execute. TACACS+ also logs all administrative activity, providing comprehensive auditing capabilities for security and compliance.

A) TACACS+ is correct because it separates authentication, authorization, and accounting functions, enabling granular control over administrative access. Administrators can be assigned roles that limit their command permissions, ensuring that only authorized personnel can make configuration changes. Each command issued is logged centrally in ISE or an integrated logging system, creating an auditable trail of administrative actions. This is critical in large enterprise networks where multiple administrators may access devices simultaneously. TACACS+ integrates with enterprise identity stores such as Active Directory, providing centralized authentication and ensuring consistent policy enforcement.

B) RADIUS is incorrect because RADIUS is primarily used for authenticating endpoints connecting to the network and does not provide command-level authorization for administrators.

C) HTTP is incorrect because HTTP portals are used for user-facing functions such as BYOD onboarding or guest registration, not for administrative command control.

D) SNMP is incorrect because SNMP is used for monitoring devices and collecting operational statistics, not for authenticating administrators or logging commands.

TACACS+ is essential for maintaining secure administrative access and accountability. By integrating with Cisco ISE, it ensures that administrative privileges are enforced consistently across devices, logs all activity for auditing, and provides detailed reports to meet compliance and security requirements. TACACS+ reduces the risk of unauthorized changes, enhances visibility into administrative actions, and supports role-based access management in complex network environments. It also allows network operators to implement policy changes centrally, which is critical for operational efficiency and security in large-scale deployments.

Explanation:

The correct answer is A) Profiling. Cisco ISE Profiling is used to automatically identify and classify endpoints based on device attributes. Profiling collects data such as MAC addresses, operating system types, device manufacturers, DHCP, HTTP headers, SNMP, and NetFlow information. Based on this data, ISE categorizes devices into profiles such as corporate laptops, mobile phones, IoT devices, or unknown endpoints. These profiles are then used in authorization policies to enforce dynamic network access controls.

A) Profiling is correct because it enables administrators to create context-aware access policies. For example, corporate laptops may be granted full network access, mobile devices may be restricted to specific VLANs, and unknown devices may be placed in quarantine for further inspection. Profiling integrates with posture and BYOD services, allowing dynamic adjustment of access policies based on endpoint type and compliance. This reduces administrative overhead and improves security by ensuring that all devices are identified and assigned appropriate access levels. Profiling also provides valuable reporting for operational monitoring, capacity planning, and auditing.

B) Posture is incorrect because posture evaluates the compliance of devices against security policies, such as antivirus or firewall status, rather than classifying devices.

C) BYOD is incorrect because BYOD focuses on onboarding employee-owned devices, certificate deployment, and secure access rather than automatic classification.

D) Guest Access is incorrect because guest access manages temporary users and sponsor approvals, not endpoint profiling.

Profiling is critical for maintaining visibility and control over all devices connecting to the network. Automated endpoint classification improves security by enabling dynamic policy enforcement, reduces the risk of unauthorized access, and ensures that endpoints are placed in appropriate network segments. Profiling also allows IT administrators to generate reports on device types, usage trends, and security posture, providing actionable insights for network planning, threat detection, and regulatory compliance. By combining profiling with posture, BYOD, and TrustSec, Cisco ISE creates a dynamic and secure network environment.

Answer: A) PSN

Explanation:

The correct answer is A) PSN. Policy Service Nodes (PSNs) are responsible for enforcing network access policies in real time. When endpoints attempt to connect to the network, PSNs process authentication requests sent via RADIUS or other protocols, evaluate the endpoint against authorization policies, and enforce decisions such as VLAN assignments, ACLs, or Security Group Tags (SGTs). PSNs integrate contextual information from profiling, posture, and BYOD workflows to make dynamic, context-aware access decisions.

A) PSN is correct because it handles high volumes of authentication and authorization requests, ensuring that network access policies are applied consistently and reliably. For instance, a corporate laptop may be granted full access, whereas a non-compliant BYOD device may be quarantined or redirected to a remediation portal. PSNs also log all access events for reporting, auditing, and troubleshooting purposes. By separating enforcement from policy management (handled by PAN) and monitoring (handled by MnT), PSNs enable scalable, high-availability deployments that can handle large enterprise networks.

B) PAN is incorrect because the Policy Administration Node defines and distributes policies but does not enforce them in real time.

C) MnT is incorrect because Monitoring and Troubleshooting nodes provide operational visibility and reporting but do not enforce access policies.

D) Guest Node is incorrect because Guest Nodes manage temporary user registration and sponsor approvals rather than real-time enforcement of network access policies.

PSNs are crucial for ensuring that all endpoints are evaluated against current access policies and receive appropriate network permissions. Their integration with posture, BYOD, and profiling allows dynamic, adaptive security enforcement. PSNs also provide logging for operational monitoring and compliance reporting. By offloading enforcement to PSNs, ISE ensures consistent, scalable, and secure access control across the enterprise network, providing high availability and reliability in dynamic environments.

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

Answer: A) Posture

Explanation:

The correct answer is A) Posture. Cisco ISE Posture evaluates endpoint compliance against predefined security policies before granting access to the network. Posture checks typically include antivirus or antimalware presence, firewall configuration, operating system patch levels, and other security settings. Endpoints that fail posture assessments may be restricted to a remediation VLAN or redirected to a remediation portal where corrective actions can be performed.

A) Posture is correct because it allows organizations to enforce compliance-based access control dynamically. Posture can operate in agent-based or agentless modes. Agent-based posture uses a lightweight client installed on the endpoint to assess compliance, while agentless posture uses network-sourced information such as DHCP, HTTP headers, or SNMP data. Compliance results are integrated with authorization policies to assign VLANs, ACLs, or SGTs appropriately. For example, a laptop without updated antivirus software might be restricted to a remediation network until it meets compliance standards.

B) BYOD is incorrect because BYOD focuses on securely onboarding employee-owned devices and deploying certificates rather than enforcing compliance checks.

C) Guest Access is incorrect because guest access manages temporary user accounts and sponsor approvals, not endpoint compliance.

D) TrustSec is incorrect because TrustSec enforces identity-based segmentation using Security Group Tags, but it does not perform compliance evaluations.

Posture is a critical component of Cisco ISE’s security framework. By verifying that endpoints meet security standards, posture reduces the risk of malware or unpatched vulnerabilities propagating across the network. Integrating posture with profiling, BYOD, TrustSec, and authorization policies ensures adaptive, context-aware network access control. Posture also provides detailed logs for auditing and compliance reporting, helping administrators monitor endpoint compliance trends, enforce organizational policies, and maintain a secure network environment. It is a cornerstone of enterprise security, ensuring that only trusted and compliant devices gain access to critical resources.

Question 150

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

Answer: A) TrustSec

Explanation:

The correct answer is A) TrustSec. Cisco TrustSec provides identity-based segmentation for enterprise networks using Security Group Tags (SGTs) to represent user roles, device types, or security groups. Unlike traditional segmentation that relies on IP addresses or VLANs, TrustSec assigns SGTs to endpoints, enabling network devices to enforce access policies based on identity and context. TrustSec integrates tightly with Cisco ISE to dynamically assign SGTs based on user role, device compliance, location, and network attributes, allowing administrators to create granular access control policies that are scalable and easier to manage.

A) TrustSec is correct because it allows network policies to be abstracted from physical network topology. Administrators can define policies such as “finance devices can access accounting servers but not engineering resources,” without relying on static VLAN assignments. When a device authenticates via ISE, it is dynamically assigned an SGT, which is propagated to switches, routers, and firewalls. This ensures consistent policy enforcement across the network, regardless of where the device connects. TrustSec also integrates with posture and BYOD, enabling access policies to factor in endpoint compliance, device type, and role. For example, a corporate laptop may receive a full-access SGT, whereas a personal mobile device may receive a limited-access SGT and be placed in a restricted VLAN or ACL.

B) BYOD is incorrect because BYOD is focused on onboarding employee-owned devices, certificate distribution, and secure access, rather than network segmentation.

C) Posture is incorrect because posture evaluates endpoint security compliance before granting access but does not assign SGTs or enforce segmentation.

D) Guest Access is incorrect because guest access manages temporary users and sponsor workflows, not identity-based segmentation.

TrustSec provides enterprises with scalable, policy-driven segmentation that improves security and reduces administrative overhead. By decoupling policy enforcement from network topology, it enables more flexible designs, minimizes configuration errors, and allows consistent enforcement across wired, wireless, and VPN environments. Integration with Cisco ISE ensures that identity, device compliance, and contextual information are considered in policy enforcement, supporting zero-trust principles, dynamic access control, and regulatory compliance. TrustSec is particularly valuable in complex enterprise environments with mixed device types, mobile workforces, and distributed locations, providing secure, adaptive, and context-aware network access.

When a device attempts to connect, the PSN evaluates the request against configured policies, including identity, device type, posture compliance, and location. The PSN then enforces the decision by assigning VLANs, ACLs, or Security Group Tags (SGTs) based on the policy.

A) PSN is correct because it ensures that policies are applied dynamically and immediately, providing secure, adaptive access control. PSNs also integrate with profiling, BYOD, posture, and TrustSec to evaluate contextual information about the endpoint. For example, a compliant corporate laptop may receive full access, whereas a non-compliant device may be redirected to a remediation portal or placed in a restricted network segment. PSNs log authentication and authorization events, which can be forwarded to Monitoring and Troubleshooting (MnT) nodes for auditing and reporting purposes.

B) PAN is incorrect because the Policy Administration Node is responsible for creating and distributing policies, not real-time enforcement.

C) MnT is incorrect because Monitoring and Troubleshooting nodes aggregate logs and provide dashboards, rather than enforcing access policies.

D) Guest Node is incorrect because Guest Nodes handle temporary user registration and sponsor approvals, not policy enforcement.

PSNs are essential for scalable and reliable deployments, ensuring consistent enforcement of dynamic access policies across wired, wireless, and VPN networks. By integrating with other ISE services, PSNs provide adaptive, context-aware access while maintaining detailed logs for auditing and compliance.

Question 159

Which ISE feature evaluates endpoint compliance with antivirus, firewall, and patch policies before granting access?

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

Answer: A) Posture

Explanation:

The correct answer is A) Posture. Cisco ISE Posture evaluates endpoints to ensure they meet organizational security requirements before granting network access. Posture assessments typically include checking antivirus updates, firewall configuration, operating system patches, and other security-related attributes. Devices failing the posture evaluation may be assigned to a restricted VLAN or redirected to a remediation portal where corrective actions can be taken.

A) Posture is correct because it enforces compliance-based access control dynamically and integrates with ISE authorization policies. For example, an endpoint without up-to-date antivirus software might be placed in a remediation VLAN until it meets security standards. Posture can operate in agent-based or agentless modes, where agent-based posture uses a lightweight client on the endpoint, and agentless posture collects compliance information from network-derived sources such as DHCP or HTTP headers.

B) BYOD is incorrect because BYOD handles onboarding employee devices, not evaluating compliance.

C) Guest Access is incorrect because guest access is for temporary users, not endpoint compliance evaluation.

D) TrustSec is incorrect because TrustSec provides identity-based segmentation, not compliance evaluation.

Posture ensures that only secure and compliant devices gain network access, reducing the risk of malware or vulnerabilities spreading. It also provides detailed logging for auditing and integrates with BYOD, profiling, and TrustSec to enforce dynamic, context-aware security policies.

Question 160

Which ISE component centralizes policy creation, management, and distribution to enforcement nodes?

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

Answer: A) PAN

Explanation:

The correct answer is A) PAN. The Policy Administration Node (PAN) centralizes all policy creation, configuration, and distribution within Cisco ISE. Administrators define authentication, authorization, BYOD, posture, TrustSec, and guest access policies on the PAN. These policies are then replicated to Policy Service Nodes (PSNs), which enforce them in real time. Centralizing policy management ensures consistency across all enforcement nodes, reduces configuration errors, and simplifies administration in large-scale deployments.

A) PAN is correct because it provides a single point of management for all policies. PAN also manages system certificates, node groups, and integration with identity sources such as Active Directory. Centralized policy administration allows updates to be propagated automatically to PSNs, maintaining uniform enforcement across wired, wireless, and VPN networks. Auditing and logging within PAN track policy changes and administrative actions, supporting compliance requirements.

B) PSN is incorrect because PSNs enforce policies but do not create or distribute them.

C) MnT is incorrect because MnT aggregates logs and provides dashboards, not policy management.

D) Guest Node is incorrect because Guest Nodes manage temporary user workflows, not global policy administration.

PAN ensures scalable, secure, and consistent network access control by centralizing administrative tasks. It reduces the risk of misconfiguration, supports compliance, and integrates with posture, BYOD, TrustSec, and profiling for adaptive, context-aware enforcement.
