Answer : A

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.

Answer : D

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.

Answer : B

To control which commands managers are allowed to execute on AOS-CX switches using ClearPass Policy Manager (CPPM) as a TACACS+ server, you must configure the Shell service in the TACACS+ enforcement profile. The Shell service provides the ability to define granular access controls for commands. It supports policy-driven command authorization, which is essential in controlling administrative tasks based on roles.

Answer : D

On Aruba Mobility Controllers, dataplane captures can include wireless frames encapsulated inside GRE (for example, ERM / remote mirroring or tunneled 802.11 data). If Wireshark does not have GRE dissection enabled, these packets may appear as generic IP/UDP payloads, and the inner traffic (client frames) will not decode correctly.

MC dataplane is exactly where GRE-encapsulated user traffic is likely to appear. Enabling GRE in Wireshark allows you to see and decode the inner payload (802.11/Ethernet/IP).

MC control plane traffic is generally not GRE encapsulated data traffic.

For gateways, captures exported as ERM over UDP often require different decoding (e.g., ARUBA_ERM, not generic GRE).

Thus, the most appropriate case to ensure GRE is enabled is when the capture came from the MC dataplane Option D.

Answer : A

The existing policy permits DHCP and DNS through class1, then drops traffic matching class2, which is traffic destined for 10.0.0.0/8. However, the requirement also says all other traffic must be permitted. To make that policy complete, a final catch-all permit class must be added after the deny rule. A class that matches ''any any any'' and is referenced at the end of policy1 permits all traffic that did not match the earlier DHCP/DNS or 10.0.0.0/8 rules. Changing class2 to ignore would remove the intended deny behavior. Reversing source and destination would not meet the stated destination-based requirement. Adding action permit to class1 only affects DHCP and DNS, not all other traffic.
