HPE7-A02 Exam Questions 2026 – Real Practice Test with Verified Answers

Explanation:
Running periodic subnet scans on devices from HPE Aruba Networking ClearPass Policy Manager (CPPM) can be used to gather DHCP fingerprints, which help determine a client's device category and operating system. DHCP fingerprints are unique patterns in DHCP request packets that provide valuable information about the device type and OS, assisting in device profiling and policy enforcement.

Explanation:
When establishing a cluster of HPE Aruba Networking ClearPass servers, it is recommended to install a CA-signed certificate for HTTPS on the Subscriber before it joins the cluster. This ensures secure communication between the servers in the cluster and provides a trusted certificate for client connections.

Explanation:
The benefit of the Online Certificate Status Protocol (OCSP) is that it allows a device to query whether a single certificate is revoked or not. OCSP provides a real-time mechanism for checking the revocation status of an individual certificate, enabling devices to verify the validity of certificates quickly and efficiently.

Explanation:
Gateway Threat Count Alert
This alert indicates that the gateway has detected threats in traffic passing through it. HPE Aruba Networking Central provides tools to investigate and analyze these threats in detail.
Analysis of Each Option
A. Use HPE Aruba Networking Central tools to run a Network Check on the gateway with which the alert is associated:
Incorrect:
Network Check tools in Central are primarily used for connectivity and performance diagnostics, not for analyzing detected threats.
This does not provide insight into the specific threats triggering the Gateway Threat Count alert.
B. Use Live Monitoring on the gateway to download a packet capture of recent traffic flowing through the gateway:
Incorrect:
Live Monitoring and packet capture can provide raw traffic data, but interpreting this requires significant manual analysis.
The Gateway Threat Count alert already provides summarized threat insights that are easier to access via the threat list.
C. Check the threat list for the gateway associated with the alert. Access threat details and download packet info:
Correct:
The threat list is specifically designed to display detailed information about detected threats, such as their type, severity, and source/destination.
Administrators can access this list in Central for the affected gateway, view granular details, and even download associated packet data for deeper inspection.
D. Check the gateway's Audit Trail in HPE Aruba Networking Central for more details about the threats that triggered the alert:
Incorrect:
The Audit Trail tracks configuration changes and administrative actions, not the details of detected threats.
It is not relevant for investigating the Gateway Threat Count alert.
Final Recommendation
To gather more information about what caused the Gateway Threat Count alert to trigger, check the threat list for the associated gateway. This provides detailed threat information and the option to download packet data for further analysis.

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.
