HP HPE7-A02 Exam With Confidence Using Practice Dumps

Comprehensive Detailed Explanation

In a user-based tunneling (UBT) setup with reserved VLAN mode, VLAN 64 is used for routing traffic at the gateways. Since the IoT traffic is tunneled to the AOS-10 gateway:

On the gateways:

VLAN 64 must be configured in the iot-wired role for routing purposes.

On the switches:

VLAN 64 does not need to be configured on the access switch physical uplinks because the IoT traffic is tunneled directly to the gateway and does not rely on VLAN configurations at the access layer switches.

Reserved VLAN mode:

Ensures that traffic is encapsulated within the UBT tunnel, and VLANs like 64 are only relevant at the gateway for routing and enforcement.

Therefore, the correct configuration is to define VLAN 64 in the iot-wired role on the AOS-10 gateways and not on any physical interfaces.

Comprehensive Detailed Explanation

Traffic Match Evaluation Order:

The rules are processed in sequential order, and the first rule that matches is applied.

The added rule only denies SSH traffic to 10.1.4.0/23. Since 10.1.11.42 is not within the 10.1.4.0/23 subnet, this rule does not apply.

Next Matching Rule:

Rule 2 permits traffic to the 10.1.6.0/23 network, but this does not include 10.1.11.42.

Rule 3 denies traffic to the broader 10.1.0.0/16 network and logs it. Since 10.1.11.42 falls under this range, this rule applies, and the traffic would be logged and dropped.

Logging and Denylist Actions:

The denylist action in the new rule only applies to SSH traffic to 10.1.4.0/23. Since the destination is outside that range, the denylist is not triggered.

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.
