NEW QUESTION # 47
You are configuring ArubaOS-CX switches to tunnel client traffic to an Aruba Mobility Controller (MC).
What should you do to enhance security for control channel communications between the switches and the MC?
Answer: D
Explanation:
When configuring ArubaOS-CX switches to tunnel client traffic to an Aruba Mobility Controller (MC), securing the control channel communications is crucial to prevent unauthorized access and ensure data integrity. Option B is the correct answer as it involves configuring a long, random PAPI security key that matches on both the switches and the MC. The PAPI (Policy Access Point Interface) protocol is used for secure communication between Aruba devices, and employing a robust, randomized security key significantly enhances the security of the control channel. This setup prevents potential interception or manipulation of the control traffic between the devices.

NEW QUESTION # 48
What is a reason to set up a packet capture on an HPE Aruba Networking Mobility Controller (MC)?
Answer: C
Explanation:
Packet captures on an HPE Aruba Networking Mobility Controller (MC) are a powerful troubleshooting and analysis tool, allowing administrators to capture and analyze network traffic at various levels (e.g., control plane or data plane). The MC supports packet captures for both wired and wireless traffic, which can be filtered based on criteria such as IP address, MAC address, or port.
Option A, "The security team believes that a wireless endpoint connected to the MC is launching an attack and wants to examine the traffic more closely," is correct. Packet captures are commonly used in security investigations to analyze the traffic of a specific endpoint suspected of malicious activity. For example, if a wireless client is suspected of launching an attack (e.g., a DoS attack or data exfiltration), a packet capture on the MC can capture the client's traffic (filtered by MAC or IP address) for detailed analysis, helping the security team identify the nature of the attack.
Option B, "The company wants to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to profile devices and needs to receive HTTP User-Agent strings from the MC," is incorrect. While CPPM can use HTTP User-Agent strings for device profiling, this is typically achieved by mirroring HTTP traffic to CPPM (e.g., using a datapath mirror on the MC), not by setting up a packet capture. Packet captures are for manual analysis, not for feeding data to CPPM.
Option C, "You want the MC to analyze wireless clients' traffic at a lower level, so that the AOS firewall can control Web traffic based on the destination URL," is incorrect. The AOS firewall on the MC can control traffic based on applications or services (e.g., using deep packet inspection, DPI), but it does not support URL-based filtering directly. URL filtering typically requires an external solution (e.g., a web proxy or firewall). Packet captures are not used to enable URL-based control by the firewall.
Option D, "You want the MC to analyze wireless clients' traffic at a lower level, so that the AOS firewall can control the traffic based on application," is incorrect. The AOS firewall can already perform application-based control using DPI (if enabled), without requiring a packet capture. Packet captures are for manual analysis, not for enabling firewall functionality.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"Packet captures on the Mobility Controller are useful for troubleshooting and security investigations. For example, if the security team suspects that a wireless endpoint is launching an attack, you can set up a packet capture on the MC's data plane to capture the endpoint's traffic. Use the command packet-capture datapath <filter> (e.g., filter by the client's MAC address) to capture the traffic, which can then be analyzed to identify malicious activity." (Page 515, Packet Capture Section) Additionally, the HPE Aruba Networking Security Guide notes:
"Packet captures are a critical tool for security teams to investigate potential attacks. By capturing traffic from a specific wireless client suspected of malicious behavior, administrators can analyze the packets to determine the nature of the attack, such as a DoS attack or unauthorized data exfiltration." (Page 65, Security Troubleshooting Section)

NEW QUESTION # 49
A company is deploying ArubaOS-CX switches to support 135 employees, which will tunnel client traffic to an Aruba Mobility Controller (MC) for the MC to apply firewall policies and deep packet inspection (DPI). This MC will be dedicated to receiving traffic from the ArubaOS-CX switches.
What are the licensing requirements for the MC?
Answer: D
Explanation:
When deploying ArubaOS-CX switches that tunnel client traffic to an Aruba Mobility Controller (MC), the licensing requirements typically involve Policy Enforcement Firewall (PEF) licenses. These licenses enable the MC to enforce firewall policies and perform deep packet inspection (DPI). Therefore, for each switch tunneling traffic to the MC, a PEF license would be necessary.
NEW QUESTION # 50
Refer to the exhibit.
What is another setting that you must configure on the switch to meet these requirements?
Answer: C
Explanation:
To meet the requirements for configuring an ArubaOS-CX switch for integration with ClearPass Policy Manager (CPPM), it is necessary to set the AAA authentication login method for SSH to use the "radius" server-group, with "local" as a backup. This ensures that when an admin attempts to SSH into the switch, the authentication request is first sent to CPPM via RADIUS. If CPPM is unavailable, the switch will fall back to using local authentication12.
Here's why the other options are not correct:
Option B is incorrect because configuring a CPPM username and password on the switch that matches a CPPM admin account is not required for SSH login; rather, the switch needs to be configured to communicate with CPPM for authentication.
Option C is incorrect because while CPPM will send Aruba-Admin-Role Vendor-Specific Attributes (VSAs), the switch does not need to have port-access roles created with the same names; it needs to interpret the VSA to assign the correct role.
Option D is incorrect because disabling SSH on the default VRF and enabling it on the mgmt VRF is not related to the authentication process with CPPM.
Therefore, the correct answer is A, as setting the AAA authentication login method for SSH to the "radius" server-group with "local" as backup is a key step in ensuring that the switch can authenticate admins through CPPM while providing a fallback method12.
