Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 413

In a Cisco VXLAN based network, which of the following best describes the main function of a VXLAN Tunnel Endpoint (VTEP)?

Answer options

• A. A device that performs VXLAN encapsulation and decapsulation.
• B. It is a 24 bit segment ID that defines the broadcast domain.
• C. It is the Logical interface where the encapsulation and de-encapsulation occurs.
• D. It is a device that performs tunneling using GRE.

Correct answer: A

Explanation

The correct answer is A because a VXLAN Tunnel Endpoint (VTEP) is responsible for both encapsulating and decapsulating the VXLAN packets as they enter and leave the VXLAN overlay. Option B is incorrect as it describes the VXLAN Network Identifier (VNI), and option C, while partially correct, does not specifically highlight the encapsulation and decapsulation aspect. Option D is wrong because VTEP does not use GRE for tunneling; it primarily uses VXLAN.
