Eliminate Risk of Failure with HPE7-A02 Exam Dumps

User-Based Tunneling (UBT) with VRRP:

UBT allows traffic from authenticated users to be tunneled to an HPE Aruba Networking gateway.

In the case of VRRP, where two gateways are configured for redundancy, the AOS-CX switch will always send the traffic to the primary gateway defined in the UBT zone configuration.

The VRRP state (master/backup) does not impact the UBT decision; the UBT primary configuration takes precedence.

Option Analysis:

Option A: Incorrect. UBT does not strictly follow the VRRP master; it adheres to the UBT primary gateway configuration.

Option B: Correct. The switch tunnels all traffic to the primary gateway configured in the UBT zone.

Option C: Incorrect. UBT does not load-share traffic between gateways.

Option D: Incorrect. UBT uses the primary gateway configured in the UBT zone, not dynamically determined active devices.

RAPIDS Ad-Hoc Detection:

The alert 'Detect ad-hoc using Valid SSID' indicates that a device is broadcasting an SSID that matches a valid network SSID in ad-hoc mode. This can be an indication of an infrastructure attack or misconfiguration.

Next Steps:

Use Aruba Central floorplans or AP location data to identify the physical area where the offending device is detected.

Locate and investigate the device to determine if it is malicious or simply misconfigured.

Option Analysis:

Option A: Incorrect. While tuning thresholds is useful for reducing false positives, this step does not directly address a potential threat.

Option B: Incorrect. Faulty drivers can cause similar behavior, but this step is not immediately actionable without locating the device first.

Option C: Correct. Floorplans or AP identities help locate the threat's physical area for further investigation.

Option D: Incorrect. RAPIDS focuses on detecting devices via SSID and MAC, not IP addresses, making this approach less relevant.

RADIUS Accounting:

RADIUS accounting enables network devices to report client session details (e.g., IP addresses, session duration, bandwidth usage) to CPPM.

Interim updates ensure CPPM receives ongoing updates about the client's session, enabling accurate tracking.

Option Analysis:

Option A: Incorrect. Syslog logging sends general system logs, not client session details.

Option B: Incorrect. Dynamic authorization (CoA) handles session changes but does not provide usage tracking.

Option C: Correct. RADIUS accounting with interim updates tracks client IP addresses and bandwidth utilization.

Option D: Incorrect. IF-MAP interfaces are used for metadata sharing, not for RADIUS-based tracking.

Integration of CPDI and CPPM for Zero Trust:

CPDI (ClearPass Device Insight) identifies and profiles devices and applications on the network.

CPDI can tag devices based on their behavior or detected applications.

CPPM uses these tags to enforce policies, such as quarantining clients that violate security rules (e.g., using prohibited applications).

Option Analysis:

Option A: Incorrect. CPPM does not inform CPDI about role assignments; CPDI provides device context to CPPM.

Option B: Correct. CPDI tags clients, and CPPM uses those tags to enforce quarantine or other Zero Trust actions.

Option C: Incorrect. Custom fingerprint definitions are not part of this integration.

Option D: Incorrect. CPDI provides information about devices, not user identities.

802.1X and User Role Download:

AOS-CX switches use RADIUS attributes to dynamically download user roles from CPPM.

The HPE-User-Role VSA (Vendor-Specific Attribute) must be configured in the RADIUS enforcement profiles to specify which role the switch should apply.

Option Analysis:

Option A: Incorrect. Exporting roles in XML is not needed for dynamic role download.

Option B: Incorrect. Switches authenticate via RADIUS, not admin accounts with specific privileges.

Option C: Correct. RADIUS enforcement profiles must include the HPE-User-Role VSA to implement user role download.

Option D: Incorrect. TPM certificates are unrelated to RADIUS-based user role downloads.
