Question 31
Which Cisco ISE feature allows administrators to dynamically assign VLANs to endpoints based on authentication and authorization policies?
A) Change of Authorization
B) Policy Sets
C) Posture Assessment
D) Profiling
Answer: A
Explanation:
Change of Authorization (CoA) in Cisco ISE enables dynamic modification of active sessions on network devices. When an endpoint authenticates and is assigned an initial authorization policy, CoA allows network administrators to update the session attributes without requiring the endpoint to disconnect and reconnect. This includes dynamically assigning VLANs based on authentication results, user identity, device type, posture, or other contextual factors. For example, a device may initially be placed in a remediation VLAN for compliance checks and, once it passes posture assessment, CoA can reassign it to the production VLAN. CoA leverages RADIUS Change of Authorization messages sent to switches, wireless controllers, or VPN devices to implement these modifications in real time. This ensures that endpoints receive the appropriate level of access based on current policy evaluation, enhancing security and operational efficiency.
Policy sets provide a hierarchical framework for defining authentication and authorization rules. While policy sets determine which VLAN or access profile should apply, they do not implement dynamic updates on an existing session. CoA is the mechanism that enforces real-time changes.
Posture assessment evaluates the security compliance of endpoints but does not directly reassign VLANs. It determines whether a device meets security requirements and can trigger policy evaluation, but the dynamic application of VLAN changes requires CoA.
Profiling identifies devices based on network attributes such as MAC addresses, DHCP options, and traffic behavior. Profiling supports policy decisions by providing contextual information, but it cannot enforce real-time session changes or VLAN reassignment.
CoA works in conjunction with policy sets and posture results to apply dynamic access changes. It allows administrators to implement adaptive security policies, respond to compliance failures, and grant or restrict access without requiring session interruption. Because CoA directly executes VLAN assignments and session modifications, it is the correct answer.
Question 32
Which Cisco ISE feature enables integration with endpoint security solutions to receive real-time threat intelligence for adaptive access control?
A) pxGrid
B) Posture Assessment
C) Policy Sets
D) Profiling
Answer: A
Explanation:
PxGrid is Cisco ISE’s platform for exchanging contextual information with external security solutions, such as SIEMs, firewalls, or endpoint protection systems. It allows real-time sharing of events, alerts, and endpoint data to inform adaptive access control decisions. For example, if an endpoint is flagged by an integrated threat detection system for malware activity, pxGrid communicates this information to ISE, which can then trigger policy changes such as quarantining the device, restricting access, or enforcing additional authentication measures. PxGrid provides a standardized, bi-directional communication framework, ensuring that multiple security platforms can respond to security events consistently. It supports automated policy enforcement, threat containment, and improved operational visibility, allowing organizations to implement proactive, adaptive security.
Posture assessment evaluates endpoint compliance with predefined security requirements such as antivirus, patching, and encryption. While posture can inform access policies, it does not directly integrate with external threat detection systems or receive real-time threat intelligence. Its scope is internal compliance evaluation rather than cross-platform adaptive control.
Policy sets define rules for authentication and authorization based on identity, device type, location, and posture. While policy sets enforce decisions, they rely on information from external systems or internal assessments. They do not provide the mechanism for receiving real-time threat intelligence.
Profiling identifies device types based on MAC addresses, DHCP attributes, or traffic patterns. Profiling provides important contextual data for policy decisions but does not integrate with threat detection platforms or adjust policies based on real-time security events.
PxGrid enables adaptive network security by providing the mechanism for real-time integration with external security platforms. It ensures that endpoints flagged as risky or compromised are automatically restricted according to policy. Because it facilitates dynamic responses to external threat intelligence, pxGrid is the correct answer.
Question 33
Which Cisco ISE feature allows administrators to classify endpoints without requiring user credentials?
A) Profiling
B) Posture Assessment
C) Guest Access
D) Policy Sets
Answer: A
Explanation:
Profiling in Cisco ISE enables the identification and classification of endpoints without requiring user authentication. It works by passively observing network traffic and analyzing attributes such as MAC addresses, DHCP options, CDP/LLDP data, HTTP headers, and other protocol-level characteristics. Using this information, ISE can categorize endpoints into predefined or custom classes such as laptops, mobile devices, IP phones, printers, or IoT devices. Profiling operates independently of user credentials, making it particularly useful for devices that cannot authenticate traditionally, such as network printers, cameras, or other IoT devices. Once devices are profiled, administrators can apply tailored policies for authentication and authorization, ensuring that access is appropriate for the device type and operational context.
Posture assessment evaluates the compliance of endpoints with security policies, including antivirus, patch levels, and firewall settings. While it influences access decisions, it cannot classify devices without authentication. Posture assessment focuses on health rather than identity.
Guest access provides temporary network access for visitors or external users. It requires some form of authentication or approval process and does not passively classify devices based on network attributes. Its focus is on onboarding and controlling temporary sessions, not endpoint classification.
Policy sets define access rules based on context such as identity, device type, location, and posture. While they use profiling information to make decisions, policy sets themselves do not passively identify endpoints. Profiling feeds data into policy sets to enable appropriate policy enforcement.
Profiling allows ISE to apply policies to devices without requiring credentials, improving security for unmanaged endpoints and supporting differentiated access for diverse device types. Because it identifies devices without user input and supports adaptive policy application, profiling is the correct answer.
Question 34
Which Cisco ISE feature allows temporary network access for visitors using a self-registration or sponsor approval process?
A) Guest Access
B) Posture Assessment
C) Policy Sets
D) pxGrid
Answer: A
Explanation :
Guest access in Cisco ISE provides temporary or limited network connectivity for visitors, contractors, or temporary users. Administrators can configure portals that allow self-registration, where users provide required information to request access, or sponsor approval workflows, where an existing employee approves the guest’s access request. Guest access allows administrators to define authentication methods, session durations, bandwidth restrictions, and access to specific resources. It also enables customization of captive portals to match organizational branding and provide instructions for registration or approval. Guest access is important for maintaining security while providing temporary connectivity, as it ensures that visitors are isolated from sensitive corporate resources and comply with organizational policies. Logs and reports from guest sessions support auditing and regulatory compliance.
Posture assessment evaluates device compliance with antivirus, patching, and firewall settings. While it enforces health-based access controls, it does not provide temporary visitor access or registration portals. Its focus is on endpoint compliance.
Policy sets define hierarchical authentication and authorization rules for employees or devices. While policy sets control access decisions, they are not designed for temporary, self-service visitor access or sponsor approval workflows.
PxGrid enables integration with external security platforms for adaptive security but does not provide portals, session limits, or temporary access for guests. Its role is contextual data sharing, not visitor onboarding.
Guest access provides a controlled, temporary access mechanism for visitors with either self-registration or sponsor approval, ensuring secure and auditable connectivity. Because it directly enables temporary access workflows, guest access is the correct answer.
Question 35
Which Cisco ISE feature allows administrators to enforce selective removal of corporate data from personal devices in BYOD environments?
A) App Protection Policies
B) Posture Assessment
C) Policy Sets
D) Guest Access
Answer: A
Explanation:
App Protection Policies in Cisco ISE enable organizations to secure corporate applications and data on personal devices while leaving personal apps and information intact. This capability is critical in Bring Your Own Device (BYOD) environments, where users own the device but require access to corporate resources. Administrators can configure policies to selectively remove corporate applications, email accounts, and sensitive data without affecting personal files or apps. This ensures that corporate information is protected, regulatory compliance is maintained, and user privacy is respected. App Protection Policies also control data sharing between managed and unmanaged applications, preventing leakage to personal apps or cloud services. In case a device is lost, stolen, or the employee leaves the organization, selective wipe can be performed remotely, removing only corporate data while leaving personal content untouched.
Posture assessment evaluates endpoint compliance, checking antivirus, patching, and firewall configurations. While it can enforce restricted access for noncompliant devices, it does not selectively remove corporate applications or data from personal devices.
Policy sets define authentication and authorization rules, evaluating contextual attributes such as device type, identity, or location. While they may use App Protection Policy results for enforcement decisions, they do not directly perform selective wipes of corporate content.
Guest access provides temporary network connectivity for visitors and does not manage corporate data or perform selective wipe. Its scope is limited to onboarding and session control.
App Protection Policies operate at the application level, enabling targeted control of corporate resources while preserving user privacy. By allowing selective removal of corporate content in BYOD scenarios, organizations maintain security without disrupting personal usage. Because this feature addresses selective wipe specifically, App Protection Policies are the correct answer.
Question 36
Which Cisco ISE feature allows administrators to enforce device compliance checks using agent-based or agentless methods before granting full network access?
A) Posture Assessment
B) Policy Sets
C) Profiling
D) Guest Access
Answer: A
Explanation :
Posture assessment in Cisco ISE is the mechanism used to evaluate endpoint compliance with security policies before granting full network access. It ensures that devices connecting to the network meet predefined requirements such as having antivirus software installed and up to date, patches applied, firewalls enabled, and disk encryption activated. Posture assessment can operate in two modes: agent-based, where a lightweight ISE posture agent is installed on the endpoint, and agentless, which uses protocols like SNMP, DHCP, or HTTP to gather health information without installing software on the endpoint. Both methods allow ISE to determine the health of the device before allowing unrestricted access to the corporate network. If the device fails to meet compliance requirements, it can be placed into a remediation VLAN, redirected to a portal with instructions for remediation, or have limited access applied until compliance is achieved. This ensures that endpoints do not pose a security risk to the network, and it supports automated enforcement of security policies in a consistent manner.
Policy sets in Cisco ISE define the authentication and authorization rules applied to endpoints and users. While policy sets may include posture results as part of the decision-making process, they do not perform the actual evaluation of endpoint health. They implement the rules after posture assessment reports compliance status.
Profiling identifies endpoints by analyzing attributes such as MAC addresses, DHCP requests, LLDP/CDP data, or HTTP headers. Profiling is critical for classifying devices and supporting context-aware policies, but it does not evaluate compliance or enforce remediation workflows. Its role is information gathering, not endpoint health enforcement.
Guest access provides temporary connectivity for visitors or external users via self-registration or sponsor approval workflows. Guest portals do not evaluate the security compliance of the devices accessing the network. Their focus is temporary access and isolation of visitors rather than enforcing endpoint security standards.
Posture assessment allows administrators to protect the network by ensuring that only compliant devices are granted full access. It integrates with policy sets to enforce rules dynamically based on the health status of the endpoint. By providing remediation workflows and leveraging agent-based or agentless evaluations, posture assessment ensures that the network maintains high security standards without impeding user productivity. Because it directly assesses endpoint compliance and enforces conditional access based on security health, posture assessment is the correct answer.
Question 37
Which Cisco ISE feature allows administrators to classify devices based on MAC addresses, DHCP attributes, and network traffic patterns for policy enforcement?
A) Profiling
B) Posture Assessment
C) Policy Sets
D) Guest Access
Answer: A
Explanation:
Profiling in Cisco ISE is used to identify and classify endpoints based on observable network attributes such as MAC addresses, DHCP requests, HTTP headers, and traffic patterns. This process allows administrators to determine the type of device attempting to access the network, such as laptops, smartphones, IP phones, printers, or IoT devices. By classifying devices, administrators can apply tailored access policies that align with device capabilities and security requirements. Profiling operates passively, without requiring user authentication, making it particularly useful for unmanaged devices or those without user credentials. Once devices are profiled, this information can be integrated with policy sets to enforce authentication and authorization rules, including VLAN assignment, SGT tagging, or access restriction based on the device type. Profiling enhances network security by providing context-aware decision-making and supporting differentiated policies across diverse devices.
Posture assessment evaluates the health and compliance of devices based on antivirus, patching, and firewall status. While posture results are used to grant or restrict access, posture assessment does not classify devices based on MAC addresses or network traffic patterns. Its primary focus is health enforcement rather than device identification.
Policy sets define the rules for authentication and authorization decisions, using attributes such as identity, device type, or location. While policy sets use information from profiling to apply access rules, they do not perform the classification themselves. Profiling feeds critical contextual information into policy sets but is a separate process.
Guest access provides temporary network access for visitors through registration portals or sponsor approval workflows. Guest portals do not classify devices based on MAC addresses, DHCP attributes, or traffic patterns. They are focused on visitor onboarding and session management rather than detailed device identification.
Profiling ensures that ISE can make informed policy decisions by identifying devices and their capabilities before applying access control rules. It allows administrators to enforce policies that differentiate between trusted corporate laptops, unmanaged IoT devices, and other endpoints, providing granular security and flexibility. Because profiling classifies devices using network attributes for policy enforcement, it is the correct answer.
Question 38
Which Cisco ISE feature allows administrators to remove corporate apps, email accounts, and data from a lost or stolen device while leaving personal data intact?
A) App Protection Policies
B) Posture Assessment
C) Policy Sets
D) Guest Access
Answer: A
Explanation :
App Protection Policies in Cisco ISE provide the ability to manage and secure corporate applications and data on personal devices in BYOD environments. These policies allow administrators to selectively remove corporate applications, email accounts, and sensitive information from endpoints while leaving personal applications, files, and data untouched. This selective wipe capability ensures that corporate data remains secure, even if a device is lost, stolen, or an employee leaves the organization, without compromising user privacy. App Protection Policies also manage how corporate apps interact with personal apps, preventing unauthorized data sharing between managed and unmanaged applications. They support automated actions such as wiping corporate content, blocking access, or enforcing security requirements, which allows IT teams to maintain compliance and security while minimizing user disruption. The policies are integrated with authentication, authorization, and device posture workflows to ensure that only compliant devices and applications access corporate resources.
Posture assessment evaluates device compliance with antivirus, patching, and firewall settings. While it can restrict access for noncompliant devices, it does not selectively remove corporate applications or data. Its purpose is device health verification rather than application management.
Policy sets define authentication and authorization rules for endpoints and users, leveraging attributes like device type, identity, and location. While policy sets may reference App Protection Policy outcomes to enforce access rules, they do not perform selective removal of corporate content themselves.
Guest access provides temporary network access for visitors via registration or approval workflows. It does not manage corporate applications or selectively wipe corporate data. Its scope is limited to session management and visitor access control.
App Protection Policies operate at the application layer to secure corporate data without affecting personal content, supporting BYOD adoption while maintaining regulatory compliance. They provide precise control over corporate applications, enabling secure management and selective wipe capabilities. Because this feature directly addresses selective removal of corporate data from personal devices, App Protection Policies are the correct answer.
Question 39
Which Cisco ISE feature allows administrators to assign Security Group Tags (SGTs) to users and endpoints to enable TrustSec-based access control?
A) Security Group Tagging
B) Posture Assessment
C) Profiling
D) Guest Access
Answer: A
Explanation :
Security Group Tagging in Cisco ISE enables administrators to assign numeric identifiers, called Security Group Tags (SGTs), to users and endpoints. SGTs represent the security group or role of the device or user within the organization and are used by TrustSec-enabled network devices to enforce access control policies. These tags allow the network to enforce segmentation based on identity rather than IP addresses or VLAN assignments, simplifying network management and improving security. Once SGTs are assigned, they are propagated throughout the network and interpreted by enforcement points, which restrict or allow communication between devices based on policy rules. Security Group Tagging can be applied dynamically during authentication and authorization, allowing administrators to segment users and devices into security groups and apply access policies consistently across large-scale deployments.
Posture assessment evaluates the compliance of endpoints with security policies, such as antivirus status, patch levels, and firewall configurations. While posture assessment may influence authorization results, it does not assign SGTs or enable TrustSec-based network segmentation.
Profiling identifies devices based on network characteristics such as MAC addresses, DHCP attributes, or traffic patterns. Profiling informs policy decisions but does not assign SGTs or control TrustSec enforcement.
Guest access provides temporary network access for visitors or contractors via registration or sponsor approval portals. It does not assign SGTs or integrate with TrustSec for identity-based segmentation.
Security Group Tagging ensures consistent, identity-based enforcement of network policies, enabling role-based segmentation, secure communication, and scalable network management. Because it directly assigns SGTs and supports TrustSec, it is the correct answer.
Question 40
Which Cisco ISE feature allows endpoints that initially fail compliance to be redirected to a remediation portal or restricted VLAN until issues are resolved?
A) Posture Assessment
B) Policy Sets
C) Profiling
D) Guest Access
Answer: A
Explanation:
Posture assessment in Cisco ISE evaluates endpoint devices against configured compliance policies, including antivirus presence, patch levels, firewall configuration, and disk encryption. When a device fails to meet the required security standards, posture assessment can automatically redirect the endpoint to a remediation portal or restricted VLAN. The remediation portal provides instructions, tools, and automated scripts to bring the device into compliance. By isolating noncompliant devices, the organization prevents security risks such as malware propagation or unauthorized access to sensitive resources. Posture assessment can operate in agent-based or agentless modes, collecting health information through a lightweight endpoint agent or using network-based checks without installing software. Once the device is remediated and meets compliance requirements, it can be dynamically reassigned to the appropriate VLAN or access level, often using Change of Authorization (CoA).
Policy sets define authentication and authorization rules based on identity, device type, location, and other contextual factors. While policy sets enforce access decisions, they rely on posture assessment to provide health status. Policy sets themselves do not perform compliance evaluation or remediation redirection.
Profiling identifies device types based on network characteristics but does not evaluate compliance or redirect devices for remediation. Its purpose is classification, not health enforcement.
Guest access provides temporary connectivity for visitors and does not evaluate endpoint compliance or redirect endpoints to restricted VLANs. It is limited to session management and controlled access for temporary users.
Posture assessment ensures that endpoints meet security standards before granting full access and provides a mechanism for remediation. By isolating or redirecting noncompliant devices, it maintains network integrity while providing a pathway to compliance. Because it directly evaluates device health and enforces remediation workflows, posture assessment is the correct answer.
Question 41
Which Cisco ISE feature allows administrators to enforce dynamic authorization policies to change a session’s access privileges in real time after initial authentication?
A) Change of Authorization
B) Policy Sets
C) Posture Assessment
D) Guest Access
Answer: A
Explanation
Change of Authorization (CoA) in Cisco ISE provides the ability to dynamically modify an active session’s access privileges after the user or device has successfully authenticated. CoA allows administrators to respond to changes in device status, user behavior, or security threats without requiring the endpoint to disconnect and re-authenticate. For example, if an endpoint initially passes posture assessment and is placed in a standard VLAN but later fails a compliance check, CoA can move the session to a restricted VLAN or remediation network instantly. This is accomplished using RADIUS Change of Authorization messages sent to switches, wireless controllers, or VPN concentrators, instructing the network device to modify session attributes such as VLAN, ACLs, downloadable policies, or session timeouts. CoA ensures that access policies are adaptive and continuously enforced, allowing administrators to respond to security incidents in real time.
Policy sets define hierarchical authentication and authorization rules based on identity, device type, location, and posture. While policy sets provide the decision framework, they do not themselves execute real-time session changes. CoA is the mechanism that applies the changes dictated by policy sets dynamically after authentication.
Posture assessment evaluates endpoint compliance against security policies such as antivirus, patch levels, firewall configuration, and disk encryption. Posture can trigger policy decisions that may be enforced via CoA, but it does not itself modify session privileges once authentication is complete.
Guest access provides temporary network connectivity for visitors or contractors via self-registration or sponsor approval portals. Guest portals do not support real-time session modifications after authentication and are limited to temporary access management.
CoA enables dynamic and adaptive network security, allowing administrators to change session privileges based on updated contextual information such as posture failures, threat intelligence, or policy adjustments. By ensuring that access rights reflect current conditions, CoA protects sensitive resources, reduces risk exposure, and supports operational flexibility. Because it directly changes session privileges in real time after initial authentication, Change of Authorization is the correct answer.
Question 42
Which Cisco ISE feature allows administrators to grant or deny access based on device health, such as patch level, antivirus, or firewall status?
A) Posture Assessment
B) Policy Sets
C) Profiling
D) Guest Access
Answer: A
Explanation
Posture assessment in Cisco ISE evaluates the security health of endpoints to determine whether they comply with the organization’s predefined security policies. It inspects attributes such as antivirus status, operating system patch levels, firewall configuration, and disk encryption. Based on these assessments, ISE can grant, restrict, or deny network access. For example, a device that is fully compliant may receive full network access, while a device with outdated antivirus or missing patches may be restricted to a remediation VLAN or portal until it becomes compliant. Posture assessment supports both agent-based and agentless methods. Agent-based posture uses a lightweight software agent installed on the endpoint to report detailed health information, whereas agentless posture uses network protocols such as SNMP, DHCP, HTTP, or RADIUS to collect compliance data without installing additional software. This dual approach provides flexibility in diverse network environments.
Policy sets define the authentication and authorization framework for users and devices, incorporating contextual information such as identity, device type, location, and posture results. While policy sets enforce access decisions, they rely on posture assessment for evaluating device health. Policy sets themselves do not perform compliance evaluation; they implement policies based on the input received from posture assessment.
Profiling identifies devices by analyzing network characteristics such as MAC addresses, DHCP attributes, CDP/LLDP data, and traffic patterns. Profiling informs policy decisions but does not evaluate device health, antivirus status, or compliance with patching policies. Its purpose is identification and classification rather than health verification.
Guest access provides temporary connectivity for visitors or contractors. It does not evaluate device health, antivirus, patch levels, or firewall status, and cannot enforce compliance-based access control. Its primary purpose is temporary network access and isolation of visitors.
Posture assessment ensures that only devices meeting security standards are granted full network access, reducing the risk of compromised or vulnerable endpoints spreading threats. By integrating with policy sets, posture assessment enables dynamic access control and remediation, maintaining both security and operational efficiency. Because it evaluates device health and enforces access based on compliance, posture assessment is the correct answer.
Question 43
Which Cisco ISE feature allows temporary network access for visitors with customizable portals and sponsor approval workflows?
A) Guest Access
B) Policy Sets
C) Posture Assessment
D) Profiling
Answer: A
Explanation
Guest access in Cisco ISE provides controlled, temporary network connectivity for visitors, contractors, or external users. Administrators can configure captive portals for self-registration, where visitors enter required information to request access, or implement sponsor approval workflows, where an internal user approves the guest’s request. Guest access allows for customizable portal branding, tailored instructions, and session restrictions, including time limits, bandwidth limits, and access to specific resources. By using guest portals, organizations can isolate visitors from sensitive corporate resources, ensuring that temporary users do not pose security risks. Guest access also supports integration with authentication sources such as Active Directory to validate sponsor credentials and control access based on user roles or groups. Logging and reporting of guest sessions provide audit trails for compliance and operational tracking.
Policy sets define hierarchical authentication and authorization rules for users and endpoints. While policy sets may enforce access for employees or devices, they are not designed for temporary visitor onboarding, self-registration, or sponsor approval workflows.
Posture assessment evaluates endpoint compliance with security policies such as antivirus, patching, and firewall status. While posture can influence access decisions for devices, it is not used to manage temporary visitor sessions or portals.
Profiling identifies device types based on network traffic patterns, MAC addresses, DHCP requests, and other attributes. Profiling informs access policies but does not create temporary access sessions or support portal-based visitor onboarding.
Guest access ensures that visitors receive secure, controlled, and temporary connectivity while protecting corporate resources. It enables self-service registration, sponsor approval workflows, and session customization, making it the correct choice for providing temporary network access with auditing and management capabilities.
Question 44
Which Cisco ISE feature allows administrators to enforce role-based access control for network administrators using AAA protocols?
A) Device Administration
B) Policy Sets
C) Posture Assessment
D) Guest Access
Answer: A
Explanation
Device Administration in Cisco Identity Services Engine (ISE) is an essential capability that provides centralized authentication, authorization, and accounting (AAA) for network administrators, enabling organizations to securely manage access to critical network devices, including routers, switches, firewalls, and wireless controllers. By centralizing administrative control, Device Administration allows organizations to define and enforce consistent policies for which commands and configuration tasks each administrator is permitted to execute, thereby improving operational security and reducing the risk of unauthorized configuration changes. This functionality is particularly important in modern network environments where multiple administrators may have varying levels of responsibilities and access privileges, and where maintaining compliance with regulatory requirements and internal security policies is critical.
One of the key features of Device Administration is the ability to implement role-based access control (RBAC). Administrators can create roles that specify the scope of permissions assigned to a user. For example, junior network engineers may be assigned a role that grants only read-only access or limited diagnostic capabilities, allowing them to monitor device status or troubleshoot issues without making configuration changes. In contrast, senior engineers or security administrators may be granted full administrative rights, enabling them to execute configuration commands, manage network interfaces, implement security policies, and perform other critical tasks. This granular control ensures that only personnel with the appropriate level of expertise and authorization can perform sensitive operations, minimizing the risk of accidental or malicious misconfigurations that could impact network stability or security.
Device Administration in Cisco ISE integrates closely with AAA protocols such as TACACS+ and RADIUS. TACACS+ allows detailed command-level authorization, ensuring that every administrative action is subject to predefined policies. When an administrator logs into a network device, TACACS+ authenticates the user, checks their assigned role, and authorizes each command they attempt to execute based on the rules associated with that role. Meanwhile, RADIUS can provide authentication and logging for network access, supporting scenarios where device access control is combined with network access control policies. This integration allows organizations to maintain comprehensive audit trails of administrative activity, capturing details such as who accessed a device, what commands were executed, and when they occurred. Such detailed logging is invaluable for troubleshooting, compliance reporting, and forensic investigations following security incidents.
Dynamic session control is another critical capability of Device Administration. Administrators can establish sessions with devices that are dynamically adjusted based on policies, ensuring that commands executed within a session are appropriate for the user’s role. Command authorization policies allow organizations to fine-tune permissions, granting access to specific commands while restricting others, which adds an additional layer of security and control. These mechanisms ensure that administrative activity is always aligned with organizational policies, even in complex network environments where multiple devices and multiple administrators are involved.
Other features in Cisco ISE, such as policy sets, posture assessment, and guest access, serve important functions but are distinct from Device Administration. Policy sets define authentication and authorization rules for endpoints and users, considering contextual factors such as device type, user identity, location, and compliance posture. While policy sets can reference role information for decisions regarding network access, they do not directly manage administrative privileges on network devices or enforce command-level RBAC. Posture assessment evaluates endpoint health, including antivirus status, patch levels, and firewall configuration, but it is focused on enforcing security compliance for endpoints rather than controlling administrative access to infrastructure devices. Guest access, meanwhile, provides temporary network connectivity for visitors or contractors, managing session approval and isolating guest users from production resources. It does not control administrative command execution or enforce RBAC for network administrators.
By centralizing the control of administrative access, Device Administration enhances security, operational consistency, and compliance. It ensures that only authorized personnel can perform specific tasks, enforces command-level permissions through RBAC, and maintains detailed audit trails of all administrative activity. Organizations can prevent unauthorized configuration changes, reduce the risk of human error, and demonstrate accountability for actions taken on critical network devices. Additionally, the integration of TACACS+ and RADIUS allows administrators to manage authentication and authorization centrally, eliminating the need for device-specific access configurations and simplifying operational management.
Device Administration in Cisco ISE is a comprehensive solution for governing administrative access across network infrastructure devices. It provides centralized authentication, command-level authorization, dynamic session control, and detailed logging, all while enforcing role-based access control to ensure that users operate within their assigned privileges. While other Cisco ISE features such as policy sets, posture assessment, and guest access contribute to endpoint access control, network security, and visitor management, only Device Administration directly manages administrative command execution and AAA for network engineers. By offering a secure, centralized, and auditable framework for administrative access, Device Administration is the correct solution for controlling privileged network operations and maintaining compliance across complex enterprise networks.
Question 45
Which Cisco ISE feature allows administrators to assign VLANs or access policies dynamically based on user identity, device type, or security compliance results?
A) Policy Sets
B) Posture Assessment
C) Guest Access
D) Profiling
Answer: A
Explanation
Policy sets in Cisco Identity Services Engine (ISE) are a fundamental component of network access control, providing a structured framework for defining and enforcing authentication and authorization rules. These rules are based on a combination of multiple contextual factors such as user identity, device type, location, security posture, and other environmental conditions. By integrating these diverse factors into a single decision-making framework, policy sets enable administrators to implement highly granular and dynamic access control policies that adapt to the specific circumstances of each access request. The hierarchical nature of policy sets allows organizations to prioritize rules and apply them in a logical order, ensuring that endpoints receive access appropriate to their security status, user role, and device characteristics.
A key function of policy sets is to determine which network privileges or VLAN assignments should be applied when a device or user attempts to authenticate. For instance, a corporate laptop that is properly configured and compliant with all security policies may be granted full access to production network resources, typically through placement on a standard VLAN or access group. Conversely, a device that is noncompliant, such as one missing critical patches or lacking up-to-date antivirus protection, may be restricted to a remediation VLAN or redirected to a captive portal where corrective actions can be taken. Policy sets also support the enforcement of multi-factor authentication requirements, ensuring that users meet additional security criteria before gaining access to sensitive resources. Furthermore, they can integrate with external identity sources, such as Active Directory or LDAP directories, to validate user credentials and group memberships as part of the access decision process.
In addition to user identity, policy sets leverage input from other Cisco ISE components, including profiling and posture assessment. Profiling provides detailed information about endpoint devices by analyzing MAC addresses, DHCP attributes, and network traffic patterns, allowing administrators to classify devices into categories such as corporate laptops, personal mobile devices, or IoT endpoints. This contextual information is critical for policy sets to apply appropriate rules, but profiling by itself does not enforce access policies or VLAN assignments. Similarly, posture assessment evaluates the compliance of endpoints with security policies, checking elements such as antivirus status, operating system patch levels, disk encryption, and firewall configuration. The results of posture assessment inform policy sets by identifying devices that may be noncompliant or high risk, which allows policy sets to dynamically adjust access privileges or quarantine measures. However, posture assessment alone does not define the hierarchical rules or make final access decisions; it simply provides input for the decision-making framework established by policy sets.
Guest access is another feature within Cisco ISE, but it serves a distinct purpose. Guest access is primarily designed to provide temporary network connectivity to visitors, contractors, or external users, and it is limited to session management, account creation, and isolation of temporary users from the main network. Unlike policy sets, guest access does not dynamically assign VLANs based on device type, user identity, or compliance status. It also does not enforce detailed authorization rules for corporate resources, as its focus is on providing controlled, temporary access rather than granular, context-aware access control.
Policy sets operate as the central logic engine that integrates all available contextual information to enforce secure and adaptive network access. They combine user identity, device type, profiling data, posture results, location, time of access, and other contextual attributes to determine the appropriate level of network access for each endpoint. By doing so, policy sets enable administrators to implement dynamic access policies that adjust in real time to the security status and context of each request. This ensures that compliant and trusted devices receive appropriate privileges, while noncompliant or unknown devices are restricted, quarantined, or redirected to remediation portals. The hierarchical structure of policy sets allows multiple conditions to be evaluated sequentially, ensuring that the most specific and relevant rules are applied first, while more general rules provide fallback policies for less-defined scenarios.
Policy sets in Cisco ISE provide a comprehensive and hierarchical framework for enforcing authentication, authorization, and access control based on a wide range of contextual factors. While posture assessment provides the compliance information and profiling supplies device and contextual data, policy sets are the mechanism that directly applies rules, assigns VLANs, enforces access permissions, and integrates all input sources to make dynamic and granular access decisions. By combining identity, device type, security compliance, and environmental context into a single, cohesive framework, policy sets ensure that network access is both secure and adaptive. Their ability to integrate multiple inputs and enforce context-aware rules makes them an essential component for maintaining secure, flexible, and policy-driven network access. Because policy sets directly enforce VLAN assignments and access privileges based on identity, device type, and compliance status, they are the correct answer in scenarios requiring structured and dynamic access control.
