A user is having trouble connecting to an AP managed by a standalone Mobility Controller (MC). What can you do to get detailed logs and debugs for that user's client?
Correct Answer: D
When troubleshooting connectivity issues for a user connecting to an AP managed by a standalone Mobility Controller (MC) in an AOS-8 architecture, detailed logs and debugs specific to the user's client are essential. The MC provides several tools for capturing logs and debugging information, including packet captures and user-specific debug logs. Option D, "In the MC UI's Diagnostics > Logs pages, add a 'user-debug' log setting for the client's MAC address," is correct. The "user-debug" feature in the MC allows administrators to enable detailed debugging for a specific client by specifying the client's MAC address. This generates logs related to the client's authentication, association, role assignment, and other activities, which are critical for troubleshooting connectivity issues. The Diagnostics > Logs pages in the MC UI provide a user-friendly way to configure this setting and view the resulting logs. Option A, "In the MC CLI, set up a control plane packet capture and filter for the client's IP address," is incorrect because control plane packet captures are used to capture management traffic (e.g., between the MC and APs or other controllers), not user traffic. Additionally, the client may not yet have an IP address if connectivity is failing, making an IP-based filter less effective. Option B, "In the MC CLI, set up a data plane packet capture and filter for the client's MAC address," is a valid troubleshooting method but is not the best choice for getting detailed logs. Data plane packet captures are useful for analyzing user traffic (e.g., to see if packets are being dropped), but they do not provide the same level of detailed logging as the "user-debug" feature, which includes authentication and association events. Option C, "In the MC UI's Traffic Analytics dashboard, look for the client's IP address," is incorrect because the Traffic Analytics dashboard is used for monitoring application usage and traffic patterns, not for detailed troubleshooting of a specific client's connectivity issues. Additionally, if the client cannot connect, it may not have an IP address or generate traffic visible in the dashboard. The HPE Aruba Networking AOS-8 8.11 User Guide states: "To troubleshoot issues for a specific wireless client, you can enable user-specific debugging using the 'user-debug' feature. In the Mobility Controller UI, navigate to Diagnostics > Logs, and add a 'user-debug' log setting for the client's MAC address. This will generate detailed logs for the client, including authentication, association, and role assignment events, which can be viewed in the Logs page. For example, to enable user-debug for a client with MAC address 00:11:22:33:44:55, add the setting 'user-debug 00:11:22:33:44:55'." (Page 512, Troubleshooting Wireless Clients Section) Additionally, the guide notes: "While packet captures (control plane or data plane) can be useful for analyzing traffic, the 'user-debug' feature provides more detailed logs for troubleshooting client-specific issues, such as failed authentication or association problems."

Question 62
You are deploying an Aruba Mobility Controller (MC). What is a best practice for setting up secure management access to the ArubaOS Web UP
Correct Answer: C
For securing management access to the ArubaOS Web UI of an Aruba Mobility Controller (MC), it is a best practice to install a certificate signed by a Certificate Authority (CA). This ensures that communications between administrators and the MC are secured with trusted encryption, which greatly reduces the risk of man-in-the-middle attacks. Using a CA-signed certificate enhances the trustworthiness of the connection over self-signed certificates, which do not offer the same level of assurance. : ArubaOS documentation on management access security.
Question 63
You have detected a Rogue AP using the Security Dashboard Which two actions should you take in responding to this event? (Select two)
Correct Answer: C,D
When responding to the detection of a Rogue AP, it's important to consider legal implications and to gather forensic evidence: You should receive permission before containing an AP (Option C), as containing it could disrupt service and may have legal implications, especially if the AP is on a network that the organization does not own. For forensic purposes, it is essential to document the event by copying out logs with relevant information, such as the time the AP was detected and the AP's MAC address (Option D). This information could be crucial if legal action is taken or if a detailed analysis of the security breach is required. Automatically containing an AP without consideration for the context (Options A and E) can be problematic, as it might inadvertently interfere with neighboring networks and cause legal issues. Immediate containment without consideration of company policy (Option B) could also violate established incident response procedures. : Aruba Networks security resources that discuss the appropriate steps in responding to security events.

Question 64
A company with 439 employees wants to deploy an open WLAN for guests. The company wants the experience to be as follows: *Guests select the WLAN and connect without having to enter a password. *Guests are redirected to a welcome web page and log in. The company also wants to provide encryption for the network for devices that are capable. Which security options should you implement for the WLAN?
Correct Answer: C
Opportunistic Wireless Encryption (OWE) provides encrypted communications on open Wi-Fi networks, which addresses the company's desire to have encryption without requiring a password for guests. It can work in transition mode, which allows for the use of OWE by clients that support it, while still permitting legacy clients to connect without encryption. Combining this with a captive portal enables the desired welcome web page for guests to log in.
Question 65
A company has a WLAN that uses Tunnel forwarding mode and WPA3-Enterprise security, supported by an Aruba Mobility Controller (MC) and campus APs (CAPs). You have been asked to capture packets from a wireless client connected to this WLAN and submit the packets to the security team. What is a guideline for this capture?
Correct Answer: A
The correct approach for capturing packets from a wireless client in a WLAN that uses Tunnel forwarding mode and WPA3-Enterprise, managed by an Aruba Mobility Controller and Campus APs, is to use an Air Monitor (AM). An AM is specifically designed to capture wireless traffic "in the air," which means it listens to the wireless signals transmitted between devices and the access points. This method ensures that the capture includes all the necessary details while maintaining the integrity and security of the data as it is transmitted over the air. Using an Air Monitor helps in analyzing the raw wireless traffic before it gets encrypted or tunneled to the Mobility Controller, providing a clear view of the wireless client's activity and interactions. The information regarding the use of Air Monitors for packet capture in such environments can be found in the Aruba Network's official documentation and configuration guides for WLAN setups and security analysis.
