Free Practice Questions for HP HPE7-A02 Exam

To capture traffic from a particular wireless client for a 15-minute period and then send the traffic in a PCAP file, you should go to the client's AP in HPE Aruba Networking Central and use the "Security" page to run a packet capture. This method allows you to directly capture the client's traffic from the AP managing the wireless connection, ensuring that you gather the relevant traffic data for analysis.

1.Centralized Management: HPE Aruba Networking Central provides a centralized interface for managing and monitoring APs, making it easy to initiate packet captures.

2.Security Page: The "Security" page in Aruba Central includes tools for running packet captures, allowing you to specify the duration and other parameters.

3.Ease of Use: This approach simplifies the process by using the built-in features of Aruba Central, avoiding the need for complex CLI commands or additional hardware.

When establishing a cluster of HPE Aruba Networking ClearPass servers, it is recommended to install a CA-signed certificate for HTTPS on the Subscriber before it joins the cluster. This ensures secure communication between the servers in the cluster and provides a trusted certificate for client connections.

1.HTTPS Security: A CA-signed certificate for HTTPS ensures that all web-based communication to and from the ClearPass server is encrypted and secure.

2.Cluster Communication: Secure communication between ClearPass nodes in the cluster is essential for synchronization and data integrity.

3.Client Trust: Clients accessing the ClearPass server will trust the CA-signed certificate, avoiding security warnings and ensuring smooth operations.

TACACS+ Enforcement Profile:

The profile specifies a Service Attribute under Aruba:Common with:

Name: Aruba-Admin-Role

Value: operators

AOS-CX Role Mapping:

On Aruba AOS-CX switches, the Aruba-Admin-Role attribute maps the authenticated user to predefined roles:

operators: Operator-level privileges (read-only access, limited commands).

administrators: Full administrator privileges.

Other roles like auditors may exist based on configuration.

Analysis:

The value operators explicitly maps the user to operator-level privileges, granting read-only access to the AOS-CX switch.

Since the Aruba-Admin-Role is correctly set and recognized, the switch assigns the appropriate role without errors.

Option Breakdown:

Option A: Correct. The switch assigns operator-level privileges based on the Aruba-Admin-Role value.

Option B: Incorrect. Administrator-level privileges require the role value to be administrators.

Option C: Incorrect. The manager is successfully authenticated and authorized; there is no error.

Option D: Incorrect. There is no reference to an auditor role in the configuration shown.

Conclusion:

The operators value in the TACACS+ enforcement profile ensures that the manager is assigned operator-level privileges on the AOS-CX switch.

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.

When using OpenSSL to obtain a certificate signed by a Certification Authority (CA), you should submit the Certificate Signing Request (CSR) file, which is file1.pem, to the CA. The CSR contains the information about the entity requesting the certificate and the public key, but not the private key, which is in file2.pem. The CA uses the information in the CSR to create and sign the certificate.

1.CSR Submission: The CSR (file1.pem) includes the public key and the entity information required by the CA to issue a certificate.

2.Private Key Security: The private key (file2.pem) should never be sent to the CA or shared; it remains securely stored on the requestor’s server.

3.Certificate Issuance: After the CA signs the CSR, the resulting certificate can be used with the private key to establish secure communications.

Hub-Spoke VPN Configuration:

HPE Aruba Central SD-WAN Orchestrator enables hub-spoke topology where branch gateways (BGWs) connect to VPN concentrators (VPNCs) located at data centers.

A key step in configuring this is defining which VPNCs the BGWs will prefer for connectivity.

The DC Preference List is configured in the BGW groups to prioritize the data centers to which BGWs connect.

Option Analysis:

Option A: Incorrect. VPN pools control IP allocation, not which branches connect to VPNCs.

Option B: Incorrect. IKE policies define key exchange mechanisms but are not part of the connection preference process.

Option C: Correct. Admins configure a DC preference list in BGW groups to determine connectivity priorities with VPNCs.

Option D: Incorrect. IPsec policies define encryption parameters at a global level, but this is not specific to the hub-spoke connection configuration.

When using HPE Aruba Networking ClearPass Device Insight (CPDI) and you need to reclassify a device to a custom type and apply this classification to all devices with similar attributes, both already discovered and newly discovered, you should follow these steps:

1.Navigate to the device details in CPDI.

2.Select the option to reclassify the device.

3.Create a user rule based on the desired attributes of the device.

4.Choose the "Save & Reclassify" option.

This process ensures that the device is reclassified according to the new custom type and that the rule is applied to all existing and future devices with matching attributes, maintaining consistent classification across the network.

Integrating HPE Aruba Networking ClearPass Policy Manager (CPPM) and HPE Aruba Networking ClearPass Device Insight (CPDI) can help a company implement Zero Trust Security by allowing CPDI to use tags to inform CPPM that clients are using prohibited applications. CPPM can then take action, such as telling the network infrastructure to quarantine those clients, ensuring that only compliant and trusted devices have network access.

1.Device Insight Tags: CPDI can monitor client behavior and tag devices that are using prohibited applications.

2.Policy Enforcement: CPPM can use these tags to apply specific enforcement actions, such as quarantining non-compliant devices.

3.Zero Trust Implementation: This integration supports Zero Trust Security by ensuring that all devices are continuously monitored and controlled based on their behavior and compliance with security policies.

To support the detection of denial of service (DoS) attacks on AOS-CX switches, deploying an NAE (Network Analytics Engine) agent to monitor control plane policing (CoPP) is the best approach. NAE agents provide real-time analytics and monitoring capabilities, allowing administrators to detect anomalies and potential DoS attacks, such as ping or ARP floods, more quickly and efficiently. Control plane policing helps protect the switch’s CPU from unnecessary or malicious traffic, and the NAE agent can alert administrators when thresholds are exceeded, providing a proactive measure to detect and mitigate DoS attacks.

To enforce 802.1X authentication for Windows domain computers to HPE Aruba Networking ClearPass Policy Manager (CPPM) and have the computers authenticate as both machines and users in the same session, you should set up TEAP (Tunneled EAP) as the authentication method. TEAP supports both machine and user authentication within a single 802.1X session, making it suitable for scenarios where both types of authentication are required simultaneously.
