A company has HPE Aruba Networking Central-managed APs. The company wants to block all clients connected through the APs from using YouTube.
Which steps should you take?
- A . Deploy gateways and have the APs tunnel traffic to the gateways. Then, enable the gateway IDS/IPS engine.
- B . Enable Client IPS at the "custom" level, and then specify the check for YouTube.
- C . Enable WebCC on all client firewall roles. Then, create WebCC category rules that deny suspicious URLs.
- D . Enable DPI. Then, create application rules to deny YouTube on the firewall roles.
D
Explanation:
To block all clients connected through HPE Aruba Networking Central-managed APs from accessing YouTube, you should enable DPI (Deep Packet Inspection) and then create application rules to deny YouTube on the firewall roles. DPI allows the network to inspect and classify traffic based on application signatures, making it possible to enforce application-specific policies. By creating rules that specifically block YouTube traffic, you can effectively prevent clients from accessing the service.
A company has AOS-CX switches. The company wants to make it simpler and faster for admins to detect denial of service (DoS) attacks, such as ping or ARP floods, launched against the switches.
What can you do to support this use case?
- A . Deploy an NAE agent on the switches to monitor control plane policing (CoPP).
- B . Implement ARP inspection on all VLANs that support end-user devices.
- C . Configure the switches to implement RADIUS accounting to HPE Aruba Networking ClearPass and enable HPE Aruba Networking ClearPass Insight.
- D . Enabling debugging of security functions on the switches.
A
Explanation:
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.
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?
- A . UBT mode set to VLAN extend
- B . A VXLAN VNI mapped to the VLAN assigned to the VolP phones
- C . VLANs assigned to the VolP phones configured on the switch uplinks
- D . A UBT reserved VLAN set to a VLAN dedicated for that purpose
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 dedicatedfor tunneling purposes and ensures that the VoIP traffic is correctly identified and tunneled to the gateway where security policies can be applied.

What is one use case for implementing user-based tunneling (UBT) on AOS-CX switches?
- A . Centralizing the distribution of wired traffic without requiring HPE Aruba Networking gateways
- B . Tunneling traffic directly to a third-party firewall in a client data center
- C . Adding 802.1X while continuing to use the existing VLAN and ACL structure in the Ethernet network
- D . Applying enhanced security features such as deep packet inspection (DPI) to wired traffic
D
Explanation:
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.

Which use case is fulfilled by applying a time range to a firewall rule on an AOS device?
- A . Enforcing the rule only during the specified time range
- B . Tuning the session timeout for sessions established with this rule
- C . Locking clients that violate the rule for the specified time range
- D . Setting the time range over which hit counts for the rule are aggregated
A
Explanation:
Applying a time range to a firewall rule on an AOS device fulfills the use case of enforcing the rule only during the specified time range. This allows administrators to control when specific firewall rules are active, which can be useful for implementing policies that only need to be in effect during certain hours, such as blocking or allowing access to specific resources outside of business hours.
