JNCIP-DC: Juniper Networks Certified Professional – Data Center (2021) — Question 7

You are configuring VXLAN on a network of QFX5100s, and are using the set vlans vlan100 vxlan unreachable-vtep-aging-timer 600 command.
What does this command do?

Answer options

• A. This command ages out a remotely learned VTEP address after 600 seconds of inactivity.
• B. This command ages out the address of the remote VTEP 600 seconds after the last learned MAC address expires.
• C. This command ages out all learned MAC addresses assigned to the VTEP after 600 seconds of inactivity.
• D. This command ages out a locally learned MAC address assigned to the VTEP after 600 seconds of inactivity.

Correct answer: B

Explanation

The correct answer is B because the command specifically sets the timer for when the address of a remote VTEP should be aged out, which is based on the expiration of the last learned MAC address. Options A, C, and D are incorrect as they either misinterpret the context of the command or refer to aging out MAC addresses rather than the VTEP address itself.
