NEW QUESTION # 131
A company uses HPE Aruba Networking APs running AOS-10, HPE Aruba Networking Central, and HPE Aruba Networking ClearPass Policy Manager (CPPM). After starting to implement TEAP to authenticate wireless clients, admins notice that all clients are showing up on APs and in HPE Aruba Networking Central with the "anonymous" username. They want to see users' actual names there.
What can they do to address this issue?
Answer: C
Explanation:
TEAP can use an anonymous outer identity to protect user privacy during the EAP exchange. That is why APs and Aruba Central might display "anonymous" instead of the authenticated username. To make the actual username visible, CPPM must return the correct identity attribute after authentication. Applying an additional RADIUS enforcement profile that specifies the TEAP Method 2 username allows the infrastructure to display the real authenticated user identity. Editing the AD source does not solve what identity is returned to the AP.
DPI and firewall visibility are unrelated to RADIUS identity reporting. Disabling RADIUS proxy or adding APs as network devices might help other deployments, but it does not directly replace anonymous TEAP identity reporting.
NEW QUESTION # 132
You have run an Active Endpoint Security Report on HPE Aruba Networking ClearPass. The report indicates that hundreds of endpoints have MAC addresses but no known IP addresses.
What is one step for addressing this issue?
Answer: D
Explanation:
When the Active Endpoint Security Report on HPE Aruba Networking ClearPass indicates that endpoints have MAC addresses but no known IP addresses, one effective step to address this issue is to add CPPM's (ClearPass Policy Manager) IP address to the IP helper list on routing switches. This configuration ensures that DHCP requests are forwarded to the ClearPass server, allowing it to track and report the IP addresses assigned to the endpoints. This helps ClearPass maintain an accurate mapping of MAC addresses to IP addresses, improving endpoint visibility and security management.
NEW QUESTION # 133
A company has several use cases for using its AOS-CX switches' HPE Aruba Networking Network Analytics Engine (NAE).
What is one guideline to keep in mind as you plan?
Answer: A
Explanation:
The Network Analytics Engine (NAE) in AOS-CX switches provides intelligent monitoring, troubleshooting, and performance analysis through predefined or custom scripts. Here's an analysis of the guidelines for NAE:
A: Each switch model has a maximum number of supported monitors, and one agent might have multiple monitors.
* Correct:
* Each AOS-CX switch model has hardware and software limitations, including the number of agents and monitors it supports.
* Monitors are data collection points for tracking specific metrics like interface statistics, CPU usage, or custom-defined parameters.
* Agents are scripts that use monitors to evaluate data, trigger actions, or generate alerts.
* Since one agent can have multiple monitors, the total number of monitors might impact the scalability of agents.
B: You can install multiple scripts on a switch, but you can deploy only one agent per script.
* Incorrect:
* Multiple agents can be deployed from the same script if they monitor different parameters or have different configurations.
* The limitation is usually related to the total number of agents and monitors supported by the switch model, not the script itself.
C: The switch will permit you to deploy as many NAE agents as you want, but they might degrade the switch functionality.
* Incorrect:
* AOS-CX enforces hardware and software limits on the number of agents and monitors. These limits are designed to prevent degradation of switch performance.
* You cannot deploy an unlimited number of agents, as the system enforces these restrictions.
D: When you use custom scripts, you can create as many agents from each script as you want.
* Incorrect:
* While you can use custom scripts to create agents, the total number of agents is subject to the switch's maximum supported limits.
* The scalability of agents is still bound by hardware and software constraints, even with custom scripts.

NEW QUESTION # 134
A company has AOS-CX switches at the access layer, managed by HPE Aruba Networking Central. You have identified suspicious activity on a wired client. You want to analyze the client's traffic with Wireshark, which you have on your management station.
What should you do?
Answer: B
Explanation:
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.

NEW QUESTION # 135
A company lacks visibility into the many different types of user and loT devices deployed in its internal network, making it hard for the security team to address those devices.
Which HPE Aruba Networking solution should you recommend to resolve this issue?
Answer: A
Explanation:
For a company that lacks visibility into various types of user and IoT devices on its internal network, HPE Aruba Networking ClearPass Device Insight (CPDI) is the recommended solution.
CPDI provides comprehensive visibility and profiling of all devices connected to the network. It uses machine learning and AI to identify and classify devices, offering detailed insights into their behavior and characteristics. This enhanced visibility enables the security team to effectively monitor and manage network devices, improving overall network security and compliance.
