You are establishing a cluster of HPE Aruba Networking ClearPass servers. (Assume that they are running version 6.9.).
For which type of certificate it is recommended to install a CA-signed certificate on the Subscriber before it joins the cluster?
- A . Database
- B . HTTPS
- C . RADIUS/EAP
- D . RadSec
B
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.
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?
- A . The recommendation has 96% confidence, and it is based on 13 classified devices.
- B . The recommendation has 98% confidence, and it is based on 5 classified devices.
- C . The recommendation has 93% confidence, and it is based on 36 classified devices.
- D . The recommendation has 100% confidence, and it is based on 4 classified devices.
A
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 company assigns a different block of VLAN IDs to each of its access layer AOS-CX switches. The switches run version 10.07. The IDs are used for standard purposes, such as for employees, VolP phones, and cameras. The company wants to apply 802.1X authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM) and then steer clients to the correct VLANs for local forwarding.
What can you do to simplify setting up this solution?
- A . Assign consistent names to VLANs of the same type across the AOS-CX switches and have user-roles reference names.
- B . Use the trunk allowed VLAN setting to assign multiple VLAN IDs to the same role.
- C . Change the VLAN IDs across the AOS-CX switches so that they are consistent.
- D . Avoid configuring the VLAN in the role; use trunk VLANs to assign multiple VLANs to the port instead.
A
Explanation:
To simplify the setup of 802.1X authentication with HPE Aruba Networking ClearPass Policy Manager (CPPM) and ensure clients are steered to the correct VLANs for local forwarding, you should assign consistent names to VLANs of the same type across the AOS-CX switches and have user-roles reference these names. This approach allows for a more straightforward configuration and management process, as the user roles can apply consistent policies based on VLAN names rather than specific IDs. It also helps in maintaining clarity and reducing errors in VLAN assignments across different switches.
Reference: Aruba’s AOS-CX configuration guides and ClearPass integration documentation emphasize the importance of using consistent naming conventions and user-role configurations for efficient network management and security enforcement.
A company has AOS-CX switches and HPE Aruba Networking ClearPass Policy Manager (CPPM). The company wants switches to implement 802.1X
authentication to CPPM and download user roles.
What is one task that you must complete on the switches to support this use case?
- A . Specify CPPM as the RADIUS server with the exact CN in CPPM’s HTTPS certificate.
- B . Install the root CA certificate for CPPM’s RADIUS certificate in a TA profile on the switches.
- C . Configure empty user-roles with names that match enforcement profile names on CPPM.
- D . Specify a ClearPass username and password that match the name and RADIUS secret in a CPPM network device entry.
B
Explanation:
To support 802.1X authentication and download user roles from HPE Aruba Networking ClearPass Policy Manager (CPPM) on AOS-CX switches, you must install the root CA certificate for CPPM’s RADIUS certificate in a Trust Anchor (TA) profile on the switches. This ensures that the switches trust the RADIUS server certificate presented by CPPM during the authentication process.

A company uses HPE Aruba Networking ClearPass Policy Manager (CPPM) as a TACACS+ server to authenticate managers on its AOS-CX switches. The company wants CPPM to control which commands managers are allowed to enter.
Which service must you add to the managers’ TACACS+ enforcement profile?
- A . Cpass:HTTP
- B . Shell
- C . ARAP
- D . Aruba:Common
B
Explanation:
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.

Refer to the Exhibit.
You have downloaded a packet capture that you generated on HPE Aruba Networking Central.
When you open the capture in Wireshark, you see the output shown in the exhibit.
What should you do in Wireshark so that you can better interpret the packets?
- A . Choose to decode UDP port 5555 packets as ARUBA_ERM and set the Aruba ERM Type to 0.
- B . Edit preferences for IEEE 802.11 and chose to ignore the Protection bit with IV.
- C . Apply the following display filter: wlan.fc.type == 1.
- D . Edit the Enabled Protocols and make sure that 802.11, GRE, and Aruba_ERM are enabled.
A
Explanation:
To better interpret the packets shown in the Wireshark capture, you should choose to decode UDP port 5555 packets as ARUBA_ERM and set the Aruba ERM Type to 0. This configuration will allow Wireshark to properly decode and display the Aruba-specific encapsulated remote mirroring (ERM) packets, providing a clearer understanding of the traffic.
