HP HPE7-A02 Exam With Confidence Using Practice Dumps

RADIUS Change of Authorization (CoA):

CoA is triggered when ClearPass determines that a client’s posture status has changed (e.g., Healthy, Quarantine).

The RADIUS enforcement policy is where you configure actions and enforcement profiles that respond to these posture changes.

Option Analysis:

Option A: Correct. RADIUS enforcement policies are used to configure actions, including triggering CoA.

Option B: Incorrect. OnGuard settings configure posture agent behavior, not enforcement rules.

Option C: Incorrect. The posture policy evaluates compliance but does not trigger CoA.

Option D: Incorrect. WEBAUTH enforcement policies are for web-based authentication, not posture-related CoA.

To minimize disruption time if an AOS-CX switch reboots while implementing DHCP snooping and ARP inspection, you should save the IP-to-MAC bindings to external storage. This ensures that the DHCP snooping and ARP inspection tables, which are crucial for preventing spoofing attacks, are preserved across reboots. When the switch restarts, it can reload these bindings from the external storage, thereby maintaining network security and reducing the downtime associated with rebuilding these tables.

1.Preserving Bindings: Saving IP-to-MAC bindings to external storage ensures that these critical security tables are not lost during a reboot, maintaining network integrity.

2.Security Continuity: This practice helps to quickly restore security features like DHCP snooping and ARP inspection, minimizing the window of vulnerability.

3.Operational Efficiency: By preserving these bindings, the switch can resume normal operations faster, reducing disruption to network services.

To support the requirement for HPE Aruba Networking ClearPass Policy Manager (CPPM) to have HTTP User-Agent strings for profiling devices, you should add the CPPM server's IP address to the IP helper list in all client VLANs on routing switches. This configuration ensures that DHCP requests and other relevant client traffic are forwarded to CPPM, allowing it to capture HTTP User-Agent strings and use them for device profiling.

1.IP Helper Configuration: Adding CPPM to the IP helper list ensures that the switch forwards DHCP and other client traffic to CPPM, enabling it to gather necessary information for profiling.

2.User-Agent Strings: By receiving client traffic, CPPM can analyze HTTP headers and capture User-Agent strings, which provide valuable information about the client's device and browser.

3.Profiling Support: This approach supports the comprehensive profiling of devices, allowing CPPM to apply appropriate policies based on detailed device information.
