Free Practice Questions for HP HPE7-A02 Exam

The preferred method for assigning clients to a role on the AOS firewall is to configure HPE Aruba Networking ClearPass Policy Manager (CPPM) to assign the role using a RADIUS enforcement profile with an Aruba-User-Role VSA (Vendor-Specific Attribute). This method allows ClearPass to dynamically assign the appropriate user roles to clients during the authentication process, ensuring that role-based access policies are consistently enforced across the network.

Access to the Onboard portal is controlled by a dedicated Pre-Auth service in ClearPass Policy Manager:

The “ClearPass Onboard Service Pre-Auth” service defines which authentication sources (e.g., AD domain, local DB, guest) are used when users log into the Onboard web portal.

To restrict access to domain users only, you edit this Pre-Auth service to use only the Active Directory auth source (and appropriate authorization checks, such as group membership).

Exam and configuration references for ClearPass Onboard clearly identify the Onboard Pre-Auth service as the place where you control who can log into the Onboard portal.

Network Settings and Provisioning profiles in Onboard govern SSID, profiles, and device configuration, not portal user authentication.

The 802.1X services for wireless control network access after onboarding, not login to the onboarding portal itself.

Therefore, to limit the portal to domain users, you should edit the ClearPass Onboard Service Pre-Auth service on CPPM → Option B.

Packet Capture in Aruba Central:

Aruba Central provides tools for remote packet captures directly from the APs.

On the "Security" page for the AP, you can initiate a packet capture session, specifying the client device and capture duration.

The traffic is captured into a PCAP file, which can be downloaded and analyzed using tools like Wireshark.

Option Analysis:

Option A: Incorrect. While possible via CLI, Aruba Central provides a simpler method for packet captures.

Option B: Correct. Aruba Central’s "Security" page allows you to capture and export client traffic efficiently.

Option C: Incorrect. The "Live Events" page focuses on monitoring events, not packet captures.

Option D: Incorrect. Port mirroring on the switch captures AP traffic but requires more manual configuration and does not isolate client-specific wireless traffic easily.

To control which commands managers are allowed to execute on AOS-CX switches using ClearPass Policy Manager (CPPM) as a TACACS+ server, you must configure the Shell service in the TACACS+ enforcement profile. The Shell service provides the ability to define granular access controls for commands. It supports policy-driven command authorization, which is essential in controlling administrative tasks based on roles.

Industry best practices for AAA (Authentication, Authorization, and Accounting) configuration in network security architectures.

The benefit of the Online Certificate Status Protocol (OCSP) is that it allows a device to query whether a single certificate is revoked or not. OCSP provides a real-time mechanism for checking the revocation status of an individual certificate, enabling devices to verify the validity of certificates quickly and efficiently.

1.Certificate Status Query: OCSP enables devices to send a query to an OCSP responder to check the revocation status of a specific certificate.

2.Real-Time Verification: This protocol offers real-time responses, ensuring that the most up-to-date status of the certificate is obtained.

3.Efficiency: OCSP is more efficient than downloading an entire Certificate Revocation List (CRL), as it only queries the status of one certificate at a time.

802.1X Authentication Modes:

Client Auth-Mode: Requires each connected endpoint to authenticate individually using 802.1X.

Device Auth-Mode: Allows the port to authenticate a device, such as an AP, as a whole. This mode works when the device bridges traffic (e.g., AP bridging SSID traffic).

AP Role Configuration:

Since the AP bridges traffic from multiple clients, you must configure the AP role to use device auth-mode.

Meanwhile, the ports on edge switches can remain in client auth-mode to enforce 802.1X for individual client connections.

Option Analysis:

Option A: Correct. This ensures the AP itself authenticates with device auth-mode, while edge ports remain in client auth-mode.

Option B: Incorrect. APs require device auth-mode for bridging, not client auth-mode.

Option C: Incorrect. Device auth-mode on all ports would not meet the security policy for clients.

Option D: Incorrect. Leaving all ports in device auth-mode does not meet the policy for 802.1X on edge ports.

Comprehensive Detailed Explanation

A non-default device posture is applied in scenarios where specific checks on a device's compliance or security state (posture) are required to grant or deny access. The correct answer is:

B. Checking whether a client has antivirus software as a condition for receiving access to resources.

This use case explicitly requires device posture assessment, which involves evaluating the device for attributes like antivirus software, patch levels, or other compliance criteria.

Non-default device posture rules are configured to assess these conditions and enforce the appropriate policy based on the device's state.

Other Options:

A. Applying threat inspection: Threat inspection rules operate independently of device posture and apply based on traffic content, not device compliance.

C. Redirecting compromised clients: This action is typically triggered based on a security event or threat detection, not directly related to device posture evaluation.

D. Integrating with ClearPass OnGuard: While OnGuard can contribute to posture assessment, it does not require a non-default device posture in the SSE rule directly.

1. The Need for Faster Threat Notifications

Admins need immediate alerts when threats are detected by the gateway's IDS/IPS functionality. Regularly checking the Security Dashboard is inefficient, so an automated notification system is essential for faster response times.

2. Explanation of Each Option

A. Set up Webhooks that are attached to the HPE Aruba Networking Central Threat Dashboard:

Incorrect:

Webhooks are useful for integrating alerts with third-party tools or custom workflows. However, setting up email notifications through global alert settings is faster and simpler for this purpose.

B. Use Syslog to integrate the gateways with HPE Aruba Networking ClearPass Policy Manager (CPPM) event processing:

Incorrect:

Syslog integration with CPPM is typically used for logging and correlating events, not for real-time notifications about threats.

CPPM is better suited for policy enforcement, not instant threat alerts.

C. Set up email notifications using HPE Aruba Networking Central's global alert settings:

Correct:

HPE Aruba Networking Central has global alert settings that allow admins to configure email notifications for specific events, such as threat detection.

This is the simplest and most effective way to ensure admins receive immediate notifications when threats are detected by the gateways.

D. Integrate HPE Aruba Networking ClearPass Device Insight (CPDI) with Central and schedule hourly reports:

Incorrect:

While CPDI integration provides enhanced device profiling, it is not directly tied to gateway IDS/IPS threat detection.

Hourly reports are not real-time notifications and would not meet the requirement for faster threat alerts.

Final Recommendation

Setting up email notifications through HPE Aruba Networking Central's global alert settings provides the most direct and efficient solution for immediate threat detection alerts.

Traffic Forwarding for APs:

In AOS-10, AP traffic forwarding can happen locally (bridged) or through tunnels to a gateway.

The VLAN settings on the "APs" role depend on whether the APs bridge the SSID traffic locally or forward it through a tunnel.

Option B: Correct. You need to know whether the traffic is bridged or tunneled to determine the VLAN assignments.

Option A: Incorrect. LURs/DURs affect role assignment but not VLAN settings for traffic forwarding.

Option C: Incorrect. Establishing tunnels with gateways is relevant to centralized traffic forwarding, not VLANs for bridged traffic.

Option D: Incorrect. AP IP addressing (static or DHCP) does not impact the VLAN for forwarded SSID traffic.
