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.

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.

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.

Gateway Threat Count Alert

This alert indicates that the gateway has detected threats in traffic passing through it. HPE Aruba Networking Central provides tools to investigate and analyze these threats in detail.

Analysis of Each Option

A. Use HPE Aruba Networking Central tools to run a Network Check on the gateway with which the alert is associated:

Incorrect:

Network Check tools in Central are primarily used for connectivity and performance diagnostics, not for analyzing detected threats.

This does not provide insight into the specific threats triggering the Gateway Threat Count alert.

B. Use Live Monitoring on the gateway to download a packet capture of recent traffic flowing through the gateway:

Incorrect:

Live Monitoring and packet capture can provide raw traffic data, but interpreting this requires significant manual analysis.

The Gateway Threat Count alert already provides summarized threat insights that are easier to access via the threat list.

C. Check the threat list for the gateway associated with the alert. Access threat details and download packet info:

Correct:

The threat list is specifically designed to display detailed information about detected threats, such as their type, severity, and source/destination.

Administrators can access this list in Central for the affected gateway, view granular details, and even download associated packet data for deeper inspection.

D. Check the gateway's Audit Trail in HPE Aruba Networking Central for more details about the threats that triggered the alert:

Incorrect:

The Audit Trail tracks configuration changes and administrative actions, not the details of detected threats.

It is not relevant for investigating the Gateway Threat Count alert.

Final Recommendation

To gather more information about what caused the Gateway Threat Count alert to trigger, check the threat list for the associated gateway. This provides detailed threat information and the option to download packet data for further analysis.

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.

If VIA clients are not receiving IP addresses from the configured VPN pool, one setting to check is whether the pool is associated with the role to which the VIA clients are being assigned. The association between the IP pool and the role ensures that clients assigned to that role receive IP addresses from the correct pool.

1.Role Association: Each role can be associated with a specific IP pool, ensuring that clients assigned to the role receive addresses from the intended pool.

2.IP Allocation: Proper configuration of the IP pool and its association with the role is crucial for correct IP address allocation.

3.VIA Configuration: Ensuring that all settings, including IP pool associations, are correctly configured, facilitates seamless client connectivity.

The use case for the HPE Aruba Networking ClearPass OnGuard dissolvable agent is implementing a one-time compliance scan. The dissolvable agent is designed to perform a compliance check without requiring a permanent installation on the client device. This is ideal for environments where a quick, temporary assessment of the device's security posture is needed without the overhead of a persistent agent.

1.Dissolvable Agent: The dissolvable agent is downloaded and executed on the client device for a single session, performing the necessary compliance checks before being removed automatically.

2.One-time Compliance Scan: This method is particularly useful for guest or unmanaged devices where a temporary compliance scan is sufficient to ensure security standards are met.

3.Minimal Impact: Since the agent does not persist on the client device, it minimizes the impact on the user's system and does not require ongoing maintenance or updates.

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.

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.

HPE Aruba Networking SSE is a cloud-delivered Security Service Edge platform that provides secure web gateway, ZTNA, CASB/DLP, and cloud firewall functions. Threat detection for remote web browsing relies heavily on full traffic inspection, including SSL inspection, URL filtering, and malware scanning.

In Aruba SSE deployments that protect web access from campus/branch or remote users, you:

Integrate the on-prem gateway or AOS-10 environment with SSE using an external web profile, which defines how traffic is sent to SSE.

Within that profile, you enable SSL inspection so that SSE can decrypt and inspect HTTPS traffic, allowing advanced threat detection, DLP, and malware scanning.

Option A: Custom file security profiles can tune malware scanning, but using a non-default profile is not mandatory for basic threat detection.

Option B: SSE already includes built-in anti-malware and sandboxing; it doesn’t require a separate third-party antivirus integration for core features.

Option C: Connectors in SSE are used mainly to reach private applications (ZTNA), not to “reach remote users” for general web browsing.

Therefore, an essential part of enabling threat detection for web browsing is creating an external web profile that enables SSL inspection → Option D.
