What is one use case for implementing user-based tunneling (UBT) on AOS-CX switches?

  1. Centralizing the distribution of wired traffic without requiring HPE Aruba Networking gateways
  2. Tunneling traffic directly to a third-party firewall in a client data center
  3. Adding 802.1X while continuing to use the existing VLAN and ACL structure in the Ethernet network
  4. Applying enhanced security features such as deep packet inspection (DPI) to wired traffic

Answer(s): D

Explanation:

Implementing user-based tunneling (UBT) on AOS-CX switches is beneficial for applying enhanced security features such as deep packet inspection (DPI) to wired traffic. UBT allows the traffic from specific users or devices to be tunneled to a central controller or security appliance where advanced security policies, including DPI, can be applied. This approach ensures that even wired traffic benefits from the same level of security and inspection typically available for wireless traffic, thus enhancing overall network security.


Reference:

Aruba's documentation on UBT and AOS-CX configuration guides detail how to set up user-based tunneling and the benefits of applying advanced security features like DPI to tunneled traffic.



A company has HPE Aruba Networking APs running AOS-10 that connect to AOS-CX switches. The APs will:

. Authenticate as 802.1X supplicants to HPE Aruba Networking ClearPass Policy Manager (CPPM)

. Be assigned to the "APs" role on the switches

. Have their traffic forwarded locally

What information do you need to help you determine the VLAN settings for the "APs" role?

  1. Whether the APs have static or DHCP-assigned IP addresses
  2. Whether the switches are using local user-roles (LURs) or downloadable user-roles (DURs)
  3. Whether the switches have established tunnels with an HPE Aruba Networking gateway
  4. Whether the APs bridge or tunnel traffic on their SSIDs

Answer(s): D

Explanation:

To determine the VLAN settings for the "APs" role on AOS-CX switches, it is crucial to know whether the APs bridge or tunnel traffic on their SSIDs. If the APs are bridging traffic, the VLAN settings on the switch need to align with the VLANs used by the SSIDs. If the APs are tunneling traffic to a controller or gateway, the VLAN settings might differ as the traffic is encapsulated and forwarded through the tunnel. Understanding this aspect ensures that the VLAN configuration on the switches correctly supports the traffic forwarding method employed by the APs.


Reference:

Aruba's AOS-10 and AOS-CX documentation provide guidance on VLAN configuration and traffic forwarding methods, highlighting the importance of aligning VLAN settings with the APs' traffic handling mode.



Your company wants to implement Tunneled EAP (TEAP).

How can you set up HPE Aruba Networking ClearPass Policy Manager (CPPM) to enforce certificated- based authentication for clients using TEAP?

  1. For the service using TEAP, set the authentication source to an internal database.
  2. Select a service certificate when you specify TEAP as a service's authentication method.
  3. Create an authentication method named "TEAP" with the type set to EAP-TLS.
  4. Select an EAP-TLS-type authentication method for the TEAP method's inner method.

Answer(s): D

Explanation:

To set up HPE Aruba Networking ClearPass Policy Manager (CPPM) to enforce certificate-based authentication for clients using Tunneled EAP (TEAP), you need to select an EAP-TLS-type authentication method for TEAP's inner method. TEAP allows for a combination of certificate-based (EAP-TLS) and password-based (EAP-MSCHAPv2) authentication. By choosing EAP-TLS as the inner method, you ensure that the clients are authenticated using their certificates, thus enforcing certificate-based authentication within the TEAP framework.


Reference:

Aruba ClearPass documentation provides detailed steps for configuring TEAP and selecting appropriate inner authentication methods to ensure secure certificate-based client authentication.



Admins have recently turned on Wireless IDS/IPS infrastructure detection at the high level on HPE Aruba Networking APs.
When you check WIDS events, you see several RTS rate and CTS rate anomalies, which were triggered by neighboring APs.

What can you interpret from this event?

  1. These neighboring APs are likely to be wireless clients that are inappropriately bridging their wired and wireless NICs; you should track down and remove them.
  2. These neighboring APs might be hackers trying to launch a DoS, but are more likely operating normally; you should start by tuning the event thresholds.
  3. These neighboring APs are actually rogue APs, and you should enable wireless tarpit containment on them.
  4. These neighboring APs are actually rogue APs, and you should enable wireless de-authentication containment on them.

Answer(s): B

Explanation:

When Wireless IDS/IPS infrastructure detection reports RTS (Request to Send) and CTS (Clear to Send) rate anomalies triggered by neighboring APs, it is often an indication of unusual, but not necessarily malicious, behavior. These anomalies can be caused by neighboring APs operating normally but under specific conditions that trigger the alerts. Before assuming a security threat, it is recommended to tune the event thresholds to better match the environment and reduce false positives. This approach helps to distinguish between normal operations and potential DoS attacks.


Reference:

Aruba's Wireless IDS/IPS configuration guides provide information on interpreting events, adjusting thresholds, and distinguishing between legitimate and malicious activities in a wireless network environment.



HPE Aruba Networking Central displays an alert about an Infrastructure Attack that was detected. You go to the Security > RAPIDS events and see that the attack was "Detect adhoc using Valid SSID."

What is one possible next step?

  1. Use HPE Aruba Networking Central floorplans or the detecting AP identities to locate the general area for the threat.
  2. Look for the IP address associated with the offender and then check for that IP address among HPE Aruba Networking Central clients.
  3. Make sure that you have tuned the threshold for that check, as false positives are common for it.
  4. Make sure that clients have updated drivers, as faulty drivers are a common explanation for this attack type.

Answer(s): A

Explanation:

When HPE Aruba Networking Central detects an Infrastructure Attack, such as "Detect adhoc using

Valid SSID," the next step is to locate the general area of the threat. You can use HPE Aruba Networking Central floorplans or the identities of the detecting APs to pinpoint the approximate location of the adhoc network. This allows you to physically investigate and address the source of the threat, ensuring that unauthorized or rogue networks are quickly identified and mitigated.


Reference:

Aruba Central documentation and RAPIDS events management guides offer strategies for locating and responding to detected security threats, emphasizing the use of network tools and floorplans to effectively address potential vulnerabilities.
