NEW QUESTION # 59
A company has wired VolP phones, which transmit tagged traffic and connect to AOS-CX switches. The company wants to tunnel the phones' traffic to an HPE Aruba Networking gateway for applying security policies.
What is part of the correct configuration on the AOS-CX switches?
- A. UBT mode set to VLAN extend
- B. A VXLAN VNI mapped to the VLAN assigned to the VolP phones
- C. A UBT reserved VLAN set to a VLAN dedicated for that purpose
- D. VLANs assigned to the VolP phones configured on the switch uplinks
Answer: C
Explanation:
To tunnel VoIP phone traffic from AOS-CX switches to an HPE Aruba Networking gateway, you need to configure a User-Based Tunneling (UBT) reserved VLAN on the switches. This VLAN is dedicated for tunneling purposes and ensures that the VoIP traffic is correctly identified and tunneled to the gateway where security policies can be applied.
1.UBT Configuration: Setting a UBT reserved VLAN ensures that the switch knows which VLAN to use for tunneling traffic to the gateway.
2.Traffic Tunneling: The reserved VLAN helps in segregating the VoIP traffic, ensuring it is handled securely and according to the configured policies at the gateway.
3.Policy Application: By tunneling the traffic, the gateway can apply advanced security policies to the VoIP traffic.
Reference: Aruba's AOS-CX and UBT configuration guides detail the steps for setting up reserved VLANs for tunneling traffic to gateways.

NEW QUESTION # 62
A company issues user certificates to domain computers using its Windows CA and the default user certificate template. You have set up HPE Aruba Networking ClearPass Policy Manager (CPPM) to authenticate 802.1X clients with those certificates. However, during tests, you receive an error that authorization has failed because the usernames do not exist in the authentication source.
What is one way to fix this issue and enable clients to successfully authenticate with certificates?
- A. Change the authentication method list to include both PEAP MSCHAPv2 and EAP-TLS.
- B. Configure rules to strip the domain name from the username.
- C. Add the ClearPass Onboard local repository to the authentication source list.
- D. Remove EAP-TLS from the authentication method list and add TEAP there instead.
Answer: B
Explanation:
To fix the issue where authorization fails because the usernames do not exist in the authentication source, you can configure rules in HPE Aruba Networking ClearPass Policy Manager (CPPM) to strip the domain name from the username. When certificates are issued by a Windows CA, the username in the certificate often includes the domain (e.g., [email protected]). ClearPass might not be able to find this format in the authentication source. By stripping the domain name, you ensure that ClearPass searches for just the username (e.g., user) in the authentication source, allowing successful authentication.
NEW QUESTION # 63
HPE Aruba Networking ClearPass Device Insight (CPDI) could not classify some endpoints using system and user rules. Using machine learning, it did assign those endpoints to a cluster and discover a recommendation.
In which of these circumstances does CPDI automatically classify the endpoints based on that recommendation?

- B. The recommendation has 100% confidence, and it is based on 4 classified devices.
- C. The recommendation has 96% confidence, and it is based on 13 classified devices.
- D. The recommendation has 93% confidence, and it is based on 36 classified devices.
Answer: C
Explanation:
Comprehensive Detailed Explanation
HPE Aruba Networking ClearPass Device Insight (CPDI) uses machine learning to assign endpoints to clusters and provide classification recommendations. For CPDI to automatically classify endpoints, specific thresholds of confidence and supporting classified devices must be met.
The generally required thresholds are:
* Minimum Confidence Level: Typically, CPDI requires a recommendation confidence level of at least
95%.
* Minimum Supporting Devices: CPDI needs a cluster to include at least 10 classified devices to ensure the recommendation is statistically meaningful.
Analysis of Each Option:
* A. 96% confidence with 13 classified devices: Meets both thresholds (confidence > 95% and # 10 devices). CPDI will automatically classify endpoints in this scenario.
* B. 98% confidence with 5 classified devices: Confidence level is sufficient, but the cluster lacks the minimum required 10 classified devices. Automatic classification does not occur.
* C. 93% confidence with 36 classified devices: The confidence level is below the required 95%.
Automatic classification does not occur.
* D. 100% confidence with 4 classified devices: Confidence is ideal, but there are insufficient supporting classified devices. Automatic classification does not occur.

NEW QUESTION # 68
You have configured an AOS-CX switch to implement 802.1X on edge ports. Assume ports operate in the default auth-mode. VolP phones are assigned to the
"voice" role and need to send traffic that is tagged for VLAN 12.
Where should you configure VLAN 12?
- A. As a trunk allowed VLAN on edge ports and the trunk native VLAN in the "voice" role
- B. As the trunk native VLAN in the "voice" role (and not in the edge port settings)
- C. As the trunk native VLAN on edge ports and the trunk native VLAN on the "voice" role
- D. As the allowed trunk VLAN in the "voice" role (and not in the edge port settings)
Answer: D
Explanation:
When configuring 802.1X authentication on edge ports of an AOS-CX switch and assigning VoIP phones to a
"voice" role, the correct approach is to configure VLAN 12 as the allowed trunk VLAN in the "voice" role.
This setup ensures that traffic tagged for VLAN 12 is appropriately managed by the role applied to the VoIP phones. In AOS-CX switches, the role-based VLAN configuration allows for more granular control and ensures that the VoIP phones' traffic is handled correctly without altering the edge port settings, which typically operate with default settings for authentication.

The exhibit shows the 802.1X-related settings for Windows domain clients. What should admins change to make the settings follow best security practices?
- A. Specify at least two server names under the "Connect to these servers" field.
- B. Clear the check box for using simple certificate selection and select the desired certificate manually.
- C. Under the "Connect to these servers" field, use a wildcard in the server name.
- D. Select the desired Trusted Root Certificate Authority and select the check box next to "Don't prompt users."
Answer: A
Explanation:
To follow best security practices for 802.1X authentication settings in Windows domain clients:
* Specify at least two server names under "Connect to these servers":
* Admins should explicitly list trusted RADIUS server names (e.g., radius.example.com) to prevent the client from connecting to unauthorized or rogue servers.
* This mitigates man-in-the-middle (MITM) attacks where an attacker attempts to present their own RADIUS server.
* Select the desired Trusted Root Certificate Authority and "Don't prompt users":
* Select the Trusted Root CA that issued the RADIUS server's certificate. This ensures clients validate the correct server certificate during the EAP-TLS/PEAP authentication process.
* Enabling "Don't prompt users" ensures end users are not confused or tricked into accepting certificates from untrusted servers.
* Why the other options are incorrect:
* Option C: Incorrect. Wildcards in server names (e.g., *.example.com) weaken security and allow broader matching, increasing the risk of rogue servers.
* Option D: Incorrect. Clearing "Use simple certificate selection" requires users to select certificates manually, which can lead to errors and usability issues. Simple certificate selection is recommended when properly configured.
Recommended Settings for Best Security Practices:
* Server Validation: Specify the exact RADIUS server names in the "Connect to these servers" field.
* Root CA Validation: Ensure only the correct Trusted Root Certificate Authority is selected.
* User Prompts: Enable "Don't prompt users" to enforce automatic and secure authentication without user intervention.
