Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 958

What is a characteristic of VXLAN?

Answer options

• A. It uses VTEPs to encapsulate and de-encapsulate frames.
• B. It has a 12-bit network identifier.
• C. It uses TCP for transport.
• D. It extends Layer 2 and Layer 3 overlay networks over a Layer 2 underlay.

Correct answer: A

Explanation

The correct answer is A because VXLAN utilizes Virtual Tunnel Endpoints (VTEPs) for the encapsulation and de-encapsulation processes of Ethernet frames. Option B is incorrect as VXLAN uses a 24-bit network identifier. Option C is false because VXLAN typically uses UDP for transport, not TCP. Option D, while related to VXLAN's function, does not specifically identify a characteristic of VXLAN itself.
