(Note that the HPE Aruba Networking Central interface shown here might look slightly different from what you see in your HPE Aruba Networking Central interface as versions change; however, similar concepts continue to apply.)

An HPE Aruba Networking 9x00 gateway is part of an HPE Aruba Networking Central group that has the settings shown in the exhibit.
What would cause the gateway to drop traffic as part of its IDPS settings?

  1. Its site-to-site VPN connections failing
  2. Traffic matching a rule in the active ruleset
  3. Its IDPS engine failing
  4. Traffic showing anomalous behavior

Answer(s): B

Explanation:

In the exhibit, the HPE Aruba Networking Central settings for the 9x00 gateway show that traffic inspection is enabled, and the gateway is set to operate in IDS (Intrusion Detection System) mode with the fail strategy set to "Block". This configuration means that the gateway will drop traffic if it matches a rule in the active ruleset.

1. Active Ruleset: The ruleset version 9861 is active, and the gateway is configured to automatically update the ruleset daily.
2. Traffic Matching Rules: When traffic matches a rule in the active ruleset, it is flagged as suspicious or malicious.
3. Block Mode: Since the fail strategy is set to "Block", any traffic that matches a rule in the active ruleset will be dropped to prevent potential threats.


Reference:

The documentation for HPE Aruba Networking Central and gateway IDS/IPS configuration provides detailed information on how traffic is inspected and the implications of different fail strategies, including blocking traffic that matches the active ruleset.



A company has wired VolP phones, which transmit tagged traffic and connect to AOS-CX switches. The company wants to tunnel the phones' traffic to an HPE Aruba Networking gateway for applying security policies.

What is part of the correct configuration on the AOS-CX switches?

  1. UBT mode set to VLAN extend
  2. A VXLAN VNI mapped to the VLAN assigned to the VolP phones
  3. VLANs assigned to the VolP phones configured on the switch uplinks
  4. A UBT reserved VLAN set to a VLAN dedicated for that purpose

Answer(s): D

Explanation:

To tunnel VoIP phone traffic from AOS-CX switches to an HPE Aruba Networking gateway, you need to configure a User-Based Tunneling (UBT) reserved VLAN on the switches. This VLAN is dedicated for tunneling purposes and ensures that the VoIP traffic is correctly identified and tunneled to the gateway where security policies can be applied.

1. UBT Configuration: Setting a UBT reserved VLAN ensures that the switch knows which VLAN to use for tunneling traffic to the gateway.
2. Traffic Tunneling: The reserved VLAN helps in segregating the VoIP traffic, ensuring it is handled securely and according to the configured policies at the gateway.

3. Policy Application: By tunneling the traffic, the gateway can apply advanced security policies to the VoIP traffic.


Reference:

Aruba's AOS-CX and UBT configuration guides detail the steps for setting up reserved VLANs for tunneling traffic to gateways.



You are establishing a cluster of HPE Aruba Networking ClearPass servers. (Assume that they are running version 6.9.).

For which type of certificate it is recommended to install a CA-signed certificate on the Subscriber before it joins the cluster?

  1. Database
  2. HTTPS
  3. RADIUS/EAP
  4. RadSec

Answer(s): B

Explanation:

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.


Reference:

ClearPass documentation and best practices for clustering and certificate management recommend installing CA-signed certificates for secure HTTPS communication.



You are setting up an HPE Aruba Networking VIA solution for a company. You have already created a VPN pool with IP addresses for the remote clients. During tests, however, the clients do not receive IP addresses from that pool.

What is one setting to check?

  1. That the pool uses valid, public IP addresses that are assigned to the company
  2. That the pool is associated with the role to which the VIA clients are being assigned
  3. That the pool uses an IP subnet that is different from any subnet configured on the VPNC
  4. That the pool is referenced in the clients' VIA Connection Profile

Answer(s): B

Explanation:

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.


Reference:

Aruba's VIA configuration guides provide detailed steps for setting up VPN pools and associating them with client roles to ensure correct IP address allocation.
