HPE Network Switching Professional HPE7-A08 Exam Questions
Question 1
You are implementing HPE Aruba Networking CX switches in a hotel environment. Which feature would allow you to use a single subnet for the wired guests, allowing them to utilize only default gateway services and communicate with each other in a conference room but not elsewhere?
Answer : B
In a hotel environment where a single subnet is used for wired guests, but guest devices in a conference room need to communicate with each other (and with the default gateway), while remaining isolated from other guests elsewhere, Community VLANs are appropriate.
Community VLANs allow hosts within the same VLAN community to communicate with each other and the default gateway but are isolated from hosts in other communities.
Isolated VLANs block communication between ports and only allow communication to the gateway.
Therefore, assigning conference room guests to a community VLAN and the gateway to a primary VLAN allows the desired communication model.

Question 2
What directly affects the MCS used by wireless stations? (Select two.)
Answer : A, D
Question 3
Refer to the exhibit.
A network administrator is validating client connectivity and executes the show command shown in the exhibit. Which authentication method was used by the wireless station?
Answer : B
Question 4
Refer to the exhibit.
To which devices has AP-1 established tunnels?
Answer : A
Question 5
What are valid NAE agent actions? (Select two)
Answer : A, C
Valid Network Analytics Engine (NAE) agent actions include:
Running CLI commands (Option A), allowing automated command execution for remediation or data collection.
Generating local system logs (Option C) for event tracking and audit purposes.
Other options:
Generating SNMP traps (B) and starting/stopping packet captures (D) are not typical NAE actions.
Creating a new TAC case (E) is an external process, not an automated NAE action.

Question 6
You are troubleshooting a complex routing issue after a recent change. Your customer has just called and reported that the issue now impacts all users. What should you do next?
Answer : A
When a recent routing change causes an outage affecting all users, the recommended immediate action is to restore the last-known working configuration to quickly return the network to a stable state. This is critical to minimize downtime and impact.
Asking customers to send logs or explaining the issue takes time and delays remediation.
Collecting show tech and opening TAC cases can be done after restoring service.
Hence, the quickest way to mitigate the impact is to restore the last known good configuration.

Question 7
Refer to the exhibit.
A university runs its own TV station in the city. The IT department deploys a multimedia server so the TV productions can be sent out to the entire campus over the IP network using multicast-based communications. In order to improve the bandwidth consumption, PIM Sparse Mode and IGMP Snooping features are enabled.
When wireless users join the multicast groups, all users connected to the same WLAN experience poor network performance. However, wired users are not affected in this way. While troubleshooting, the network administrator saves the packet captures shown in the exhibit and concludes that all users, even those not joining the multicast group, receive the same multicast flow at slow speeds.
Which features should the network administrator enable to fix the problem?
Answer : C
