HP HPE7-A02 Exam With Confidence Using Practice Dumps

To assign managers to groups on the AOS-CX switch by name using HPE Aruba Networking ClearPass Policy Manager (CPPM) as a TACACS+ server, you should add the Aruba

service to the TACACS+ enforcement profile and set the Aruba-Admin-Role to the group name. This configuration ensures that the appropriate administrative roles are assigned to managers based on their group membership, allowing for role-based access control on the AOS-CX switches.

Why a Mirror Session Is the Correct Choice

To analyze a wired client’s traffic with Wireshark, you need the traffic mirrored to your management station where Wireshark is installed. The most effective way to achieve this is by configuring a mirror session on the AOS-CX switch, specifying the client port as the source and your management station as the destination.

Analysis of Each Option

A. Access the client's switch's CLI from your management station. Access the switch shell and run a TCP dump on the client port:

Incorrect:

AOS-CX switches do not natively support packet capture (e.g., tcpdump) directly on the switch CLI.

This approach is not feasible for capturing and analyzing live client traffic.

B. Go to the client's switch in HPE Aruba Networking Central. Use the "Security" page to run a packet capture:

Incorrect:

HPE Aruba Networking Central provides security insights but does not directly support initiating packet captures for detailed analysis.

Traffic analysis with tools like Wireshark requires local packet capture at the management station.

C. Set up a policy that implements a captive portal redirect to your management station. Apply that policy to the client's port:

Incorrect:

Captive portals are designed for user authentication and redirection, not traffic analysis.

This would disrupt the client’s network activity without enabling traffic analysis in Wireshark.

D. Set up a mirror session on the client's switch; set the client port as the source and your station IP address as the tunnel destination:

Correct:

Mirroring the client port to your management station is the standard method for analyzing live network traffic with Wireshark.

Steps include:

Configure a mirror session on the client’s AOS-CX switch.

Set the client’s port as the source.

Set your management station as the destination using its IP address (via GRE tunnel or physical interface).

Start capturing traffic with Wireshark on the management station.

Final Recommendation

To analyze the client's traffic, configure a mirror session on the switch, set the client port as the source, and direct the traffic to your management station where Wireshark is running.

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.
