HP Aruba Certified Network Security Professional HPE7-A02 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

For a faster way to discover if a gateway starts detecting threats in traffic, admins should set up email notifications using HPE Aruba Networking Central's global alert settings. This setup ensures that the security team is promptly informed via email whenever the IDS/IPS on the gateways detects any threats, allowing for immediate investigation and response.

1. Email Notifications: By configuring email notifications, admins can receive real-time alerts directly to their inbox, reducing the time to discover and react to security incidents.

2. Global Alert Settings: HPE Aruba Networking Central's global alert settings allow for customization of alerts based on specific security events and thresholds, providing flexibility in monitoring and response.

3. Proactive Monitoring: This proactive approach ensures that the security team is always aware of potential threats without the need to constantly check the Security Dashboard manually.

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

To configure the HPE Aruba Networking VIA solution for remote employees who need to download their VIA connection profile from the VPN Concentrator (VPNC) and ensure that only those who authenticate with their domain credentials through ClearPass Policy Manager (CPPM) can do so, you need to set up a VIA Authentication Profile. This profile should use the CPPM's RADIUS server group. Once the VIA Authentication Profile is created, you need to reference this profile in the VIA Web Authentication Profile. This configuration ensures that the authentication process requires employees to validate their credentials via CPPM before they can download the VIA connection profile.

Answer : C

Internet Key Exchange (IKE)/IKEv2 plays a crucial role in an HPE Aruba Networking client-to-site VPN by helping to negotiate the IPsec Security Association (SA) automatically and securely. IKE/IKEv2 handles the authentication and key exchange processes, ensuring that both the client and the VPN gateway can establish a secure IPsec tunnel.

1. SA Negotiation: IKE/IKEv2 automates the negotiation of the Security Association, which defines the parameters for the secure IPsec tunnel.

2. Secure Authentication: It provides a secure method for authenticating the communicating parties and exchanging cryptographic keys.

3. Efficiency: Using IKE/IKEv2 simplifies the setup and maintenance of secure VPN connections, enhancing the overall security and reliability of the VPN.

Answer : A

When using 'Tips

' conditions within an 802.1X service's enforcement policy, you should enable caching roles and posture attributes from previous sessions in the service's enforcement settings. This ensures that ClearPass retains posture information from previous authentications, which is necessary for making decisions based on the current posture state of an endpoint. By caching these attributes, ClearPass can apply appropriate enforcement actions based on the device's posture status.

Answer : D

When enabling Wireless IDS/IPS infrastructure and client detection at a high level on HPE Aruba Networking APs without enabling prevention settings, HPE Aruba Networking recommends configuring detection at a custom level and adjusting settings to minimize false positives. This approach allows for effective monitoring while reducing the risk of unnecessary alerts and maintaining the accuracy of detections.

1. Custom Level Configuration: By customizing the detection settings, you can tailor the system to your specific environment, ensuring that only relevant threats are detected and reducing false positives.

2. False Positive Reduction: Disabling or tuning settings that are likely to produce false positives helps in maintaining the reliability of the detection system and prevents alert fatigue.

3. Focused Detection: Custom configuration ensures that the IDS/IPS focuses on critical detections, improving overall security posture.
