Question 106
Which Cisco ISE feature enables administrators to classify devices automatically and assign Security Group Tags (SGTs) to enforce network segmentation and access policies?
A) Profiling
B) Posture Assessment
C) Policy Sets
D) Guest Access
Answer: A
Explanation
Profiling in Cisco ISE is a powerful mechanism for automatically identifying and classifying devices on the network. It collects information from sources like DHCP requests, MAC addresses, CDP/LLDP messages, HTTP headers, and other network traffic characteristics. Profiling allows administrators to assign Security Group Tags (SGTs) dynamically based on device type, role, or risk profile. SGTs enable role-based access control and network segmentation, helping to enforce policies that limit access to sensitive resources and ensure proper network security.
Profiling is particularly important in environments with unmanaged devices, BYOD devices, or IoT endpoints. It provides visibility into all connected devices without requiring authentication, which allows administrators to identify rogue or unknown devices and segment them appropriately. Integration with Policy Sets and Change of Authorization allows the dynamic enforcement of network policies based on profiling results. For instance, an IP phone identified through profiling may be assigned an SGT for voice traffic, while a printer may be restricted to a separate VLAN with limited access to the network. This ensures that devices receive the appropriate level of access based on type, role, and context.
Posture Assessment evaluates device compliance but does not assign SGTs. Policy Sets define access rules but rely on profiling to provide device context. Guest Access provides temporary network access but does not classify devices or assign SGTs.
Profiling improves network security and operational efficiency by providing visibility, classification, and dynamic assignment of SGTs. By identifying device types and applying segmentation policies, profiling ensures adaptive, context-aware access control. Because it assigns SGTs based on device classification, Profiling is the correct answer.
Question 107
Which Cisco ISE feature allows administrators to ensure that corporate data on BYOD devices is secure while personal content remains untouched, supporting selective wipes and containerization?
A) App Protection Policies
B) Posture Assessment
C) Policy Sets
D) Guest Access
Answer: A
Explanation
App Protection Policies in Cisco ISE are designed to secure corporate applications and data on BYOD devices while maintaining user privacy by leaving personal apps and content intact. The primary mechanism is selective wiping, which allows administrators to remove corporate apps, accounts, and sensitive data without affecting personal files, photos, or applications. Containerization further isolates corporate apps from personal content, ensuring data separation and protection while complying with security and regulatory standards.
These policies enforce security controls such as preventing corporate data from being copied to unmanaged apps, restricting data sharing outside approved locations, enforcing encryption, and managing secure storage for corporate applications. When a user leaves the organization, a device is lost, or a security incident occurs, selective wipes can be triggered manually or automatically to remove corporate data while leaving personal content untouched. Integration with Posture Assessment ensures that only compliant endpoints are granted full access, while Policy Sets allow these policies to be applied dynamically based on user role, device type, or network context. Change of Authorization can also enforce these policies in real time for active sessions.
Posture Assessment checks device compliance but does not secure corporate applications or perform selective wiping. Policy Sets define access rules but do not handle application-level security. Guest Access provides temporary network connectivity but does not protect corporate apps or enforce selective wipes.
App Protection Policies are essential for securing corporate resources in BYOD environments while respecting user privacy. By enforcing containerization and selective wiping, these policies prevent data leakage and ensure regulatory compliance. Because they secure corporate applications and selectively remove corporate data without affecting personal content, App Protection Policies is the correct answer.

A) Posture Assessment
B) Policy Sets
C) Profiling
D) Guest Access
Answer: A
Explanation
Posture Assessment in Cisco ISE is a fundamental security feature that evaluates the compliance of endpoints attempting to access the network. The assessment checks whether endpoints meet corporate security policies, including antivirus installation and status, firewall configuration, operating system patch levels, disk encryption, and other security measures. By enforcing compliance, Posture Assessment ensures that endpoints do not pose a risk to the network and prevents malware propagation or unauthorized access.
The process involves interrogating the endpoint using a series of checks or probes. The collected information is evaluated against predefined compliance policies. If the endpoint passes, it is granted full access to the network. If it fails, it can be assigned limited access or redirected to a remediation network where security gaps can be addressed. This ensures that noncompliant devices cannot compromise the network. Posture Assessment integrates with Policy Sets to enforce context-aware access policies based on compliance state, user identity, device type, and other environmental factors. Change of Authorization (CoA) allows real-time adjustments to access when an endpoint’s compliance state changes during an active session.
Policy Sets define access policies based on multiple contextual attributes but rely on Posture Assessment for compliance input. Profiling identifies the device type but does not enforce compliance-based restrictions. Guest Access provides temporary network connectivity for external users but does not evaluate security compliance.
Posture Assessment is essential for maintaining a secure environment by verifying that all endpoints adhere to security standards before they are granted access. By evaluating antivirus, firewall, OS patch, and encryption status, it ensures that only secure, compliant devices connect to critical resources. Because it enforces network access based on endpoint compliance, Posture Assessment is the correct answer.

Question 116
Which Cisco ISE feature allows administrators to enforce network access restrictions for endpoints based on compliance with security policies, including antivirus, firewall, and patch levels?
A) Posture Assessment
B) Policy Sets
C) Profiling
D) Guest Access
Answer: A
Explanation
Posture Assessment in Cisco ISE is a core security mechanism that evaluates the compliance state of endpoints attempting to access the network. It examines multiple security attributes, including antivirus installation and status, firewall configuration, operating system patch levels, disk encryption, and other critical endpoint protections. By verifying these criteria before granting network access, Posture Assessment ensures that only secure and compliant devices are allowed into sensitive network segments.
The process involves interrogating the endpoint with a series of probes that collect detailed security information. The results are evaluated against predefined compliance policies, and decisions are applied dynamically through Policy Sets and Change of Authorization (CoA). If an endpoint passes all checks, full network access is granted. If it fails, the endpoint may be limited to a remediation VLAN, restricted access, or redirected to a network where corrective measures can be applied. This integration ensures adaptive and context-aware enforcement of security policies.
Policy Sets allow administrators to define network access rules but rely on Posture Assessment to evaluate compliance. Profiling classifies device types but does not assess security compliance. Guest Access provides temporary connectivity for visitors but does not enforce security checks.
Posture Assessment is essential for protecting critical resources by ensuring that endpoints meet security standards before access is granted. By continuously evaluating compliance and enforcing corrective measures, organizations reduce security risks and maintain operational integrity. Because it enforces network access restrictions based on endpoint compliance, Posture Assessment is the correct answer.
Question 117
Which Cisco ISE feature allows administrators to classify devices automatically using DHCP, MAC addresses, HTTP headers, CDP/LLDP, and other network characteristics to enforce context-aware access policies?
A) Profiling
B) Posture Assessment
C) Policy Sets
D) Guest Access
Answer: A
Explanation
Profiling in Cisco ISE provides automated device identification and classification, enabling administrators to enforce adaptive, context-aware access policies. Profiling collects information from DHCP requests, MAC addresses, HTTP headers, CDP/LLDP messages, and other traffic characteristics to determine device types such as laptops, smartphones, printers, IP cameras, and IoT devices. This information is used to assign Security Group Tags (SGTs), VLANs, or policy enforcement rules that are tailored to device type, role, or security posture.
Profiling is especially valuable in environments with unmanaged, BYOD, or IoT endpoints, where traditional authentication may not provide sufficient visibility. It allows administrators to identify rogue or unknown devices and apply segmentation policies proactively. The data collected by profiling feeds into Policy Sets, Posture Assessment, and Change of Authorization, allowing real-time, context-aware access decisions. For example, a device identified as a printer may be placed in a restricted VLAN, while a corporate laptop passing posture checks receives full network privileges.
Posture Assessment evaluates compliance but does not classify devices. Policy Sets define access rules but rely on profiling to provide device context. Guest Access provides temporary network connectivity but does not classify or profile endpoints.
Profiling enhances network security and operational efficiency by offering detailed visibility into endpoint types and automatically applying segmentation and access policies. Because it allows automatic device classification using network characteristics, Profiling is the correct answer.
Question 118
Which Cisco ISE feature enables administrators to secure corporate applications on BYOD devices while maintaining personal privacy through selective wiping and containerization?
A) App Protection Policies
B) Posture Assessment
C) Policy Sets
D) Guest Access
Answer: A
Explanation
App Protection Policies in Cisco ISE are designed to secure corporate applications and data on App Protection Policies in Cisco Identity Services Engine (ISE) are designed to provide robust security for corporate applications and data on employee-owned devices within Bring Your Own Device (BYOD) programs, while ensuring that personal content remains unaffected. As organizations increasingly adopt mobile-first strategies and allow employees to use their own devices for work purposes, securing sensitive corporate information becomes a critical priority. At the same time, employees expect that their personal data, applications, and files will not be impacted by corporate security measures. App Protection Policies address this dual need by implementing controls specifically targeted at corporate applications and data, enabling organizations to enforce security standards without interfering with personal user content.
A central feature of App Protection Policies is selective wiping. Selective wiping allows administrators to remove only corporate-managed applications, email accounts, and work-related data from a device, without deleting or impacting any personal apps, documents, photos, or other user-generated content. This feature is essential in scenarios such as employee offboarding, when a device is reported lost or stolen, or during a security incident where corporate data could be at risk. The ability to selectively remove only corporate data ensures that sensitive information is protected while respecting the privacy of the employee’s personal content. This capability reduces resistance to BYOD adoption because employees are reassured that their personal content is safe, while the organization maintains control over corporate assets.
Containerization is another important component of App Protection Policies. Through containerization, corporate applications and data are logically isolated from personal applications and content on the device. This separation ensures that corporate data remains within a secure, controlled environment, reducing the risk of accidental or intentional leakage of sensitive information. Containerization also supports encryption and secure storage of corporate data, so even if a device is compromised or lost, unauthorized parties cannot access confidential information. This layered security approach allows organizations to enforce compliance and regulatory requirements while enabling employees to use the same device for personal purposes.
App Protection Policies also provide additional security measures within managed corporate applications. These policies can enforce rules such as preventing copy-and-paste operations from corporate apps to personal apps, restricting data sharing to approved applications and platforms, and requiring encryption for corporate applications and stored data. These controls ensure that sensitive corporate information is not transferred or exposed outside of the secured environment. By managing how corporate data is handled, these policies protect intellectual property, customer information, and other confidential data from accidental or malicious exposure, while allowing personal applications to function normally without interference.
Integration with Policy Sets further enhances the effectiveness of App Protection Policies. Policy Sets allow administrators to define conditions under which specific policies are applied, such as user identity, device type, operating system, network location, or compliance posture. This integration ensures that App Protection Policies are applied dynamically based on context, providing a tailored security approach that adjusts to varying risk levels. Additionally, Change of Authorization functionality allows these policies to be applied in real time for devices that are actively connected to the network. If a device falls out of compliance or its status changes, policies can be enforced immediately, including initiating selective wipes or updating security configurations, without requiring manual intervention or user disruption.
In contrast, other Cisco ISE features do not provide the same level of application-level protection. Posture Assessment is designed to evaluate device compliance with organizational security standards, such as checking for antivirus updates, encryption, patch levels, or firewall status. While posture checks are important for assessing the security status of devices, they do not provide controls for securing corporate applications or removing corporate data. Similarly, Policy Sets define access rules that determine which devices or users can access certain network resources, but they do not manage application-level security or enforce selective wiping of corporate content. Guest Access enables temporary connectivity for visitors or non-employees but does not protect corporate applications or data in any way, and it does not differentiate between corporate and personal content.
App Protection Policies are therefore critical for organizations that implement BYOD programs. They enable organizations to protect sensitive corporate data and applications without compromising the personal content of employees. By isolating corporate applications through containerization, enforcing secure data handling rules, and allowing selective wipes, these policies ensure that corporate security requirements are met while maintaining user privacy. They also help organizations comply with regulatory and industry standards for data protection, reducing risk exposure and potential liability. Because App Protection Policies focus specifically on application-level security and selective corporate data removal, they provide the necessary capabilities to manage BYOD environments safely and effectively, making them the correct solution for securing corporate applications and sensitive data while leaving personal content untouched.
Question 119
Which Cisco ISE feature allows administrators to dynamically adjust network access privileges for active sessions based on changes in user compliance, device posture, or security events?
A) Change of Authorization (CoA)
B) Posture Assessment
C) Profiling
D) Guest Access
Answer: A
Explanation
Change of Authorization in Cisco Identity Services Engine is a powerful and essential capability designed to provide real-time, adaptive enforcement of network access policies for endpoints that are already connected to the network. Unlike traditional network access control mechanisms, where policies are typically applied only at the time of authentication, CoA allows administrators to dynamically adjust the permissions and privileges of active sessions without requiring users or devices to disconnect and reconnect. This real-time flexibility is critical in modern enterprise networks, where security posture, compliance requirements, and contextual conditions can change rapidly, and organizations must respond immediately to maintain both security and operational continuity.
CoA works by sending RADIUS Change of Authorization messages from Cisco ISE to enforcement points on the network, including switches, wireless controllers, VPN gateways, and other TrustSec-enabled devices. These messages instruct the enforcement point to modify session attributes for the connected endpoint. Common attributes that can be updated include VLAN assignments, which control network segmentation; access control lists (ACLs), which regulate traffic to and from the endpoint; and Security Group Tags, which allow TrustSec-enabled devices to enforce identity-based access policies. By applying these changes in real time, CoA ensures that endpoints remain compliant with organizational security policies and that risk is mitigated promptly whenever a security event or posture change occurs.
One of the primary use cases for CoA is when an endpoint becomes noncompliant after the initial authentication process. For example, a corporate laptop may initially meet all security requirements and be granted full access to production resources. During the session, if the device fails an antivirus or malware check, is missing a critical patch, or has a disabled firewall, CoA can trigger an immediate remediation response. This response may include moving the endpoint to a restricted or remediation VLAN, applying more restrictive ACLs, or adjusting its Security Group Tags to limit access to sensitive systems. This ensures that noncompliant devices are promptly contained, reducing the risk of compromise or lateral movement within the network, while still allowing users to maintain basic connectivity for remediation purposes.
CoA also plays a crucial role in integrating threat intelligence and external security alerts into network access decisions. When endpoints are monitored by SIEM platforms, endpoint detection and response tools, or other external security systems, pxGrid can feed real-time alerts to Cisco ISE. For example, if an endpoint exhibits suspicious behavior, such as unusual traffic patterns or malware detection, ISE can issue a CoA event to immediately enforce mitigation actions. These actions may include restricting access to sensitive resources, placing the device in a quarantined network segment, or forcing additional authentication checks. By dynamically responding to threats in real time, CoA enables organizations to implement a proactive and adaptive security posture that limits exposure while maintaining operational efficiency.
Integration with other Cisco ISE components amplifies the effectiveness of CoA. Policy Sets define the access policies and rules based on factors such as user identity, device type, location, and compliance results, but they operate primarily at the point of authentication. CoA extends the capabilities of Policy Sets by applying these rules to active sessions dynamically. Posture Assessment evaluates endpoint compliance, but it cannot enforce session changes by itself; it only provides the data required to trigger CoA events. Profiling identifies devices and their characteristics, providing contextual awareness for access decisions, but it does not modify network access once a session is active. CoA brings all these components together, allowing administrators to enforce policy changes dynamically based on real-time data from posture assessment, profiling, and security monitoring.
Another important benefit of CoA is its ability to minimize user disruption while maintaining network security. Traditional approaches that require disconnection and reauthentication can interrupt workflows, reduce productivity, and frustrate users. With CoA, changes in compliance or threat status are enforced without disconnecting the endpoint, allowing users to continue essential operations while security measures are applied in the background. This is especially valuable in large enterprise networks where multiple endpoints may require dynamic adjustments simultaneously, ensuring consistent and scalable enforcement.
Guest Access, while valuable for providing temporary connectivity to visitors and contractors, does not provide the capability to modify active session attributes based on changing conditions. It is limited to provisioning temporary accounts and assigning access permissions for a defined period. Similarly, Posture Assessment, Policy Sets, and Profiling provide critical information and decision-making context but do not actively enforce adaptive access changes for connected endpoints. CoA is the unique feature that translates real-time contextual and compliance data into immediate enforcement actions.
Change of Authorization is a critical tool in Cisco ISE that allows administrators to maintain adaptive, context-aware network security in real time. It enables the dynamic modification of session attributes, including VLAN assignments, ACLs, and Security Group Tags, for endpoints that are already connected. CoA ensures that access privileges reflect the current security posture, compliance state, and threat environment, and it works seamlessly with Policy Sets, Posture Assessment, Profiling, and pxGrid to provide comprehensive enforcement. By enforcing immediate adjustments without requiring disconnection, CoA protects the network, reduces administrative overhead, and minimizes operational disruption. Because it provides real-time enforcement of dynamic, adaptive access policies for active sessions, Change of Authorization is the correct answer.
Question 120
Which Cisco ISE feature enables organizations to provide temporary network access to visitors, contractors, or external users while isolating them from production resources?
A) Guest Access
B) Posture Assessment
C) Policy Sets
D) Profiling
Answer: A
Explanation
Guest Access in Cisco Identity Services Engine is a specialized feature that enables organizations to provide secure, temporary network connectivity for visitors, contractors, partners, or other external users who require access to corporate networks. In many modern enterprises, external users need to access the internet, email, or limited network resources during their visit or engagement. Providing this access without compromising the security of internal systems and sensitive data can be challenging. Guest Access addresses this challenge by offering a controlled, isolated environment in which temporary users can connect to the network with appropriate restrictions while ensuring internal resources remain protected. It balances the need for connectivity with the imperative of network security, allowing organizations to enforce policies that limit access according to predefined roles and requirements.
One of the central capabilities of Guest Access is the ability to create self-registration portals. These portals allow guests to enter their own information, create temporary accounts, and generate credentials for network access. The process can be fully automated or include sponsor-based approvals, where an internal employee validates the guest and authorizes access. Sponsor-based workflows ensure accountability and help organizations comply with regulatory or operational policies. These mechanisms also enhance the user experience, enabling guests to quickly and easily gain network access without requiring intervention from IT administrators for every login. Self-registration portals can include branding, terms of use, and customized instructions, which help organizations communicate network usage policies and security expectations to visitors effectively.
In addition to providing access, Guest Access ensures that temporary users are restricted to the resources necessary for their activities. Administrators can define session durations, limiting access to the time the guest is expected to be on-site. They can also enforce VLAN assignments that segment guest devices away from production networks and sensitive data stores. ACLs and Security Group Tags can be applied to restrict the scope of accessible services, ensuring that guests cannot access internal servers, administrative systems, or confidential data. For instance, visitors might have access only to the internet, internal presentation systems, or conference room resources, while the corporate LAN and production systems remain fully isolated. This level of granularity in access control is essential for maintaining operational security and preventing accidental or intentional misuse.
Guest Access integrates with other Cisco ISE components to ensure a comprehensive security posture. While Posture Assessment focuses on evaluating compliance and health of corporate-managed endpoints, it does not provide temporary visitor access or control over guest sessions. Similarly, Policy Sets define hierarchical authentication and authorization rules for users and devices, but they are primarily concerned with internal users, endpoint types, and compliance results; they do not manage guest workflows or temporary access provisioning. Profiling identifies devices and categorizes them based on attributes such as MAC address, DHCP requests, or traffic patterns, but profiling alone does not grant or control network access for external users. Guest Access fills this gap by providing a secure, structured method for granting connectivity to non-corporate endpoints in a controlled and auditable manner.
Another key feature of Guest Access is session management. Administrators can monitor active guest sessions, track bandwidth usage, and apply restrictions dynamically as needed. For example, if a guest session exceeds the allocated duration or attempts to access restricted resources, ISE can automatically terminate or limit the session. This real-time control is crucial for maintaining network integrity while still providing necessary access to temporary users. Logging and reporting capabilities are also integral to Guest Access, enabling organizations to maintain records of who accessed the network, the resources they used, and the duration of their sessions. These audit trails support compliance with corporate policies, legal requirements, and industry regulations.
Guest Access also supports scalability and customization to match the requirements of different organizational environments. In a university or educational setting, temporary credentials can be issued to visiting researchers or lecturers, while in a corporate office, contractors or auditors may be granted limited network connectivity. The customizable portals, role-based controls, and time-bound sessions allow organizations to enforce a consistent access framework across different guest types, locations, and facilities. Additionally, integration with directory services allows sponsors to authenticate and approve guests efficiently, linking external access to internal accountability.
By providing a combination of isolation, controlled privileges, temporary credentials, and workflow-based access, Guest Access ensures that temporary network users can perform their necessary tasks without introducing security risks. Guests are prevented from accessing critical production resources, and administrators retain full control over session attributes and activity monitoring. This ensures operational efficiency while minimizing potential security threats that could arise from unmanaged or unauthorized external devices.
Guest Access in Cisco ISE is designed to enable secure, temporary, and controlled connectivity for visitors, contractors, or other external users. It provides features such as self-registration portals, sponsor-based approvals, session duration management, VLAN segmentation, ACL enforcement, and audit logging. Unlike Posture Assessment, Policy Sets, or Profiling, Guest Access is specifically built for managing external users and temporary sessions. By allowing organizations to isolate and restrict guest network activity while providing necessary access, Guest Access protects internal resources and ensures compliance with corporate policies. Because it enables temporary, secure, and controlled network connectivity for external users, Guest Access is the correct answer.
