Explanation:
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.

Explanation:
Centralized Role Configuration on CPPM:
CPPM can assign roles to clients dynamically during authentication.
However, the actual ACL policies (e.g., firewall policies) must already exist and be referenced locally on the switch.
CPPM cannot directly configure ACL details on AOS-CX switches.
Option Analysis:
Option A: Correct. The role is defined on CPPM, but it references a policy pre-configured on the switch.
Option B: Incorrect. This does not align with Aruba's centralized role-based access control design.
Option C: Incorrect. CPPM cannot configure the ACL policies and classes directly; they must exist locally.
Option D: Incorrect. Policies can be referenced centrally but not fully configured on CPPM.

Explanation:
In the exhibit, the HPE Aruba Networking Central settings for the 9x00 gateway show that traffic inspection is enabled, and the gateway is set to operate in IDS (Intrusion Detection System) mode with the fail strategy set to "Block". This configuration means that the gateway will drop traffic if it matches a rule in the active ruleset.

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.
Reference: ClearPass configuration guides and best practices documentation outline the importance of integrating ClearPass with network infrastructure using IP helper addresses to ensure comprehensive endpoint visibility and management.

Explanation:
RADIUS Accounting:
RADIUS accounting enables network devices to report client session details (e.g., IP addresses, session duration, bandwidth usage) to CPPM.
Interim updates ensure CPPM receives ongoing updates about the client’s session, enabling accurate tracking.
Option Analysis:
Option A: Incorrect. Syslog logging sends general system logs, not client session details.
Option B: Incorrect. Dynamic authorization (CoA) handles session changes but does not provide usage tracking.
Option C: Correct. RADIUS accounting with interim updates tracks client IP addresses and bandwidth utilization.
Option D: Incorrect. IF-MAP interfaces are used for metadata sharing, not for RADIUS-based tracking.
