HPE7-A02 Aruba Certified Network Security Professional Exam Practice Test

Answer : D

MAC Spoofing Detection with Endpoint Conflict:

When two devices attempt to use the same MAC address, ClearPass identifies a Conflict state in the Endpoints Repository.

This condition can be used to detect and quarantine clients that spoof legitimate devices.

Option D: Correct. The Conflict EQUALS true condition identifies devices with duplicate MAC addresses.

Option A: Incorrect. Endpoint compliance checks posture, not MAC spoofing.

Option B: Incorrect. Device Insight Tags are used for profiling but do not identify conflicts.

Option C: Incorrect. Compromised devices relate to security incidents, not MAC address conflicts.

Answer : C

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.

Answer : B

HPE Aruba Central Live Monitoring:

Aruba Central provides real-time Live Monitoring of network devices, including:

Application usage statistics.

Trends and changes over time for specific devices.

This information is presented in a clear and easy-to-read format, making it ideal for examining changes in application usage over different time ranges.

Option Analysis:

Option A: Incorrect. ClearPass OnGuard monitors endpoint compliance (e.g., antivirus, OS version) but does not analyze application usage.

Option B: Correct. Aruba Central's Live Monitoring page is specifically designed for this type of analysis.

Option C: Incorrect. ClearPass Insight generates endpoint security reports but does not track application usage.

Option D: Incorrect. ClearPass Device Insight (CPDI) focuses on device profiling and identification, not continuous application monitoring.

Answer : A

Installing Agents for SSE (Secure Service Edge):

Agents installed on remote users' devices allow posture checks (e.g., antivirus status, OS version) to ensure compliance.

Based on the results of the posture checks, different permissions and security policies can be applied dynamically.

This improves the security posture of remote users before granting access to resources.

Option A: Correct. Agents enable posture checks and enforce conditional access based on compliance.

Option B: Incorrect. Admins manage SSE policies centrally, not via agents.

Option C: Incorrect. Access to private servers via SSH does not require agents; it relies on policies and tunnels.

Option D: Incorrect. Local sandboxing is generally a function of endpoint protection solutions, not SSE agents.

Answer : D

Tag Updates Action - 'Apply for All Tag Updates':

This setting ensures that all updated tags from Device Insight (CPDI) are applied dynamically.

It is particularly useful when you want to trigger Change of Authorization (CoA) without explicitly predefining the tag values.

Option D: Correct. This setting allows CPPM to issue CoAs automatically for updated tags without requiring prior configuration of specific tags.

Option A: Incorrect. The setting is not directly related to reducing the poll interval latency.

Option B: Incorrect. Disconnecting devices based on dangerous tags would require predefined enforcement rules.

Option C: Incorrect. Posture information updates do not directly rely on this setting.

Answer : A

Comprehensive Detailed Explanation

The requirement is to permit HTTPS traffic from clients to the 10.2.12.0/24 subnet.

ZoneC is configured to drop all HTTPS traffic to the 10.2.0.0/16 subnet. Therefore, the first match in the zoneC class (priority 10) will drop the desired traffic.

To override this behavior, you must add a higher-priority rule (lower rule number) to zoneC that explicitly matches 10.2.12.0/24 and permits the traffic.

Thus, adding the rule 5 match any 10.2.12.0/24 eq https to zoneC ensures the desired traffic is permitted while maintaining the drop behavior for the rest of 10.2.0.0/16.

Answer : A

Comprehensive Detailed Explanation

The configuration includes the command aaa authentication allow-fail-through, which specifies that if the TACACS+ server fails to respond (e.g., times out), the switch will proceed to the next authentication method in the sequence, which is local. In this scenario:

The switch first attempts to authenticate the user against the TACACS+ server.

When the TACACS+ server fails to respond, the switch falls back to local authentication.

The user netadmin is a local account configured on the switch and belongs to the operators group.

As a result, the user is successfully authenticated locally and is granted operator level access.
