HPE Aruba Certified Campus Access Expert (ACAEX) — Question 21

You are helping an onsite network technician bring up an HPE Aruba Networking 9004 gateway with ZTP for a branch office. The technician was told to plug in any port for the ZTP process to start.
Thirty minutes after the gateway was plugged in, new users started to complain they were no longer able to get to the internet. One user who reported the issue stated their IP address is 172.16.0.81. However, the branch office network is supposed to be on 10.231.81.0/24.
What should the technician do to alleviate the issue and get the ZTP process started correctly?

Answer options

• A. Move the cable on the gateway to G0/0/1, and add the device’s MAC and Serial number in HPE Aruba Networking Central.
• B. Factory default and reboot the gateway to restart the process.
• C. Turn off the DHCP scope on the gateway, and set DNS correctly on the gateway to reach HPE Aruba Networking Activate.
• D. Move the cable on the gateway from port G0/0/1 to port G0/0/0.

Correct answer: D

Explanation

The correct choice is D because moving the cable to port G0/0/0 is necessary to ensure the gateway is connected to the correct network segment that matches the expected IP address range. Option A is incorrect as it would not address the immediate issue of incorrect port usage. Option B would reset the device but not resolve the port connection issue. Option C would not solve the connectivity problem since the DHCP scope should be enabled for ZTP to work correctly.
