HP Aruba Certified Network Security Professional HPE7-A02 Exam Practice Test

Answer : A

To control which commands managers are allowed to enter on AOS-CX switches using HPE Aruba Networking ClearPass Policy Manager (CPPM) as a TACACS+ server, you need to add the Shell service to the TACACS+ enforcement profiles for the managers. This service allows you to define and enforce specific command sets and access privileges for users authenticated via TACACS+. By configuring the Shell service in the enforcement profile, you can specify the commands that are permitted or denied for the managers, ensuring controlled and secure access to the switch's command-line interface.

Answer : D

Implementing user-based tunneling (UBT) on AOS-CX switches is beneficial for applying enhanced security features such as deep packet inspection (DPI) to wired traffic. UBT allows the traffic from specific users or devices to be tunneled to a central controller or security appliance where advanced security policies, including DPI, can be applied. This approach ensures that even wired traffic benefits from the same level of security and inspection typically available for wireless traffic, thus enhancing overall network security.

Answer : C

In a client-to-site VPN based on tunnel-mode IPsec, the remote clients and a gateway at the main site are responsible for the IPsec encapsulation. The remote clients initiate the VPN connection and encapsulate their traffic in IPsec, which is then decapsulated by the gateway at the main site.

1. IPsec Encapsulation: The remote clients encapsulate their traffic using IPsec protocols before sending it over the internet to the main site.

2. Gateway Role: The gateway at the main site receives the encapsulated traffic, decapsulates it, and forwards it to the internal network. Similarly, traffic from the main site to the remote clients is encapsulated by the gateway and decapsulated by the clients.

3. Security: This setup ensures that data is securely transmitted between the remote clients and the main site, protecting it from eavesdropping and tampering.

Answer : B

To ensure that HPE Aruba Networking APs (AOS-10) properly interact with HPE Aruba Networking ClearPass Policy Manager (CPPM) and dynamically update a client's enforcement profile based on new profile and posture information, you should enable Dynamic Authorization in the RADIUS server settings for CPPM. This allows ClearPass to send Change of Authorization (CoA) requests to the APs, prompting them to reapply the appropriate enforcement profiles based on updated information.

1. Dynamic Authorization: Enabling this feature allows ClearPass to dynamically push changes to the APs whenever there is new relevant information about a client's profile or posture.

2. Change of Authorization (CoA): This mechanism ensures that clients are assigned the correct enforcement profiles in real-time, based on the latest data.

3. Enhanced Policy Enforcement: This setup helps in maintaining accurate and up-to-date policy enforcement for clients on the network.

Answer : D

After installing an HPE Aruba Networking Network Analytic Engine (NAE) script on an AOS-CX switch, the additional step required to start the monitoring is to create an agent from the script. The agent is responsible for executing the script and collecting the monitoring data as defined by the script parameters.

1. Script Installation: Installing the script provides the logic and parameters for monitoring.

2. Agent Creation: Creating an agent from the script activates the monitoring process, allowing the NAE to begin tracking the specified function.

3. Operational Step: This step ensures that the monitoring logic is applied and the data collection starts as per the script's configuration.

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.

Answer : A

Comprehensive Detailed Explanation

To prohibit users from uploading and downloading files from Dropbox using HPE Aruba Networking SSE (Secure Service Edge), you need to configure web access policies. This typically involves:

Adding a web category to the SSE configuration that includes Dropbox.

The SSE solution uses category-based filtering to block access to specific applications or services, such as Dropbox, based on their classification.

Other Options:

B . Installing the SSE root certificate is required for enabling SSL inspection, but this does not directly control access to Dropbox.

C and D. Deploying a connector is not necessary for this purpose as the enforcement is done via SSE policies, not by directly interfacing with Dropbox or remote users.
