HP Aruba Certified Network Security Professional HPE7-A02 Exam Questions

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

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 : B

User-Based Tunneling supports Zero Trust by allowing organizations to enforce consistent role-based policies for wired and wireless users. Instead of trusting a device because it is physically connected to the LAN, the network uses identity, role, and context to determine access. UBT can tunnel selected wired traffic from AOS-CX switches to gateways where centralized firewall policies are applied. This allows wired users to receive enforcement similar to wireless users. Zero Trust requires least-privilege access and consistent policy based on identity and device context, not broad network placement. UBT is not mainly about VXLAN, universal LAN encryption, or cloud-zone extension. Its main Zero Trust value is consistent identity-based access enforcement.

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 : A

When HPE Aruba Networking ClearPass Device Insight (CPDI) shows a recommendation for 'Windows 8/10' with 70% accuracy for a generic device cluster, it means that CPDI has detected that these devices match about 70% of the system rule criteria for defining 'Windows 8/10' devices. This percentage indicates the confidence level based on the observed characteristics and behavior of the devices, helping administrators understand the likelihood that these devices are indeed running Windows 8 or 10.

Answer : A

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 . 96% confidence with 13 classified devices: Meets both thresholds (confidence > 95% and 10 devices). CPDI will automatically classify endpoints in this scenario.

B . 98% confidence with 5 classified devices: Confidence level is sufficient, but the cluster lacks the minimum required 10 classified devices. Automatic classification does not occur.

C . 93% confidence with 36 classified devices: The confidence level is below the required 95%. Automatic classification does not occur.

D . 100% confidence with 4 classified devices: Confidence is ideal, but there are insufficient supporting classified devices. Automatic classification does not occur.

Answer : A

Comprehensive Detailed Explanation

Virtual Network Based Tunneling (VNBT) is the appropriate technology for this use case because:

Traffic Steering: VNBT enables traffic from specific clients or devices to be tunneled through a predefined network path. This allows traffic to pass through intermediate devices such as third-party security appliances.

Policy Enforcement: VNBT can be configured to route traffic based on roles, VLANs, or other policy definitions, ensuring that only specified traffic flows are redirected to the security appliance.

Scalability: This approach simplifies the redirection of traffic without requiring complex physical rewiring or changes to the underlying network topology.

Other Options:

MC-LAG: Primarily used for high-availability and redundancy in multi-chassis link aggregation scenarios, not for traffic redirection through appliances.

Network Analytics Engine (NAE): Used for monitoring and analytics, not traffic steering or forwarding.

Device Profiles: Helps automate switch port configurations for specific device types but does not handle traffic redirection.
