Pearson HPE7-A02 New Attempt

Subnet Scan Requirements for Profiling:

For ClearPass to scan and profile devices in a subnet, the Data Port must be enabled on the ClearPass server and connected to the network.

This ensures that ClearPass can send and receive the required packets for device discovery and profiling.

Option Analysis:

Option A: Incorrect. SSH accounts are not required for subnet scanning.

Option B: Incorrect. WMI probing is for Windows systems, not Linux devices.

Option C: Correct. The Data Port is essential for subnet scans and must be properly configured and connected.

Option D: Incorrect. SNMP is used for network device monitoring, not Linux device profiling.

TACACS+ Enforcement Profile:

The profile specifies a Service Attribute under Aruba:Common with:

Name: Aruba-Admin-Role

Value: operators

AOS-CX Role Mapping:

On Aruba AOS-CX switches, the Aruba-Admin-Role attribute maps the authenticated user to predefined roles:

operators: Operator-level privileges (read-only access, limited commands).

administrators: Full administrator privileges.

Other roles like auditors may exist based on configuration.

Analysis:

The value operators explicitly maps the user to operator-level privileges, granting read-only access to the AOS-CX switch.

Since the Aruba-Admin-Role is correctly set and recognized, the switch assigns the appropriate role without errors.

Option Breakdown:

Option A: Correct. The switch assigns operator-level privileges based on the Aruba-Admin-Role value.

Option B: Incorrect. Administrator-level privileges require the role value to be administrators.

Option C: Incorrect. The manager is successfully authenticated and authorized; there is no error.

Option D: Incorrect. There is no reference to an auditor role in the configuration shown.

Conclusion:

The operators value in the TACACS+ enforcement profile ensures that the manager is assigned operator-level privileges on the AOS-CX switch.

To support the detection of denial of service (DoS) attacks on AOS-CX switches, deploying an NAE (Network Analytics Engine) agent to monitor control plane policing (CoPP) is the best approach. NAE agents provide real-time analytics and monitoring capabilities, allowing administrators to detect anomalies and potential DoS attacks, such as ping or ARP floods, more quickly and efficiently. Control plane policing helps protect the switch’s CPU from unnecessary or malicious traffic, and the NAE agent can alert administrators when thresholds are exceeded, providing a proactive measure to detect and mitigate DoS attacks.

To ensure that HPE Aruba Networking ClearPass Policy Manager (CPPM) can apply the correct access levels based on a client's device category after discovering new clients, you need to enable the "Profile Endpoints" option in the Service tab. This option allows CPPM to profile and categorize endpoints dynamically, ensuring that the appropriate access levels are applied based on the device's characteristics. Enabling this feature ensures that new devices are accurately profiled and that access policies can be enforced based on the updated device information.
