Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 181

Which entity is responsible for maintaining Layer 2 isolation between segments in a VXLAN environment?

Answer options

• A. VNID
• B. switch fabric
• C. VTEP
• D. host switch

Correct answer: C

Explanation

The VTEP (VXLAN Tunnel Endpoint) is responsible for encapsulating and decapsulating VXLAN packets, thus maintaining Layer 2 isolation between different segments. The VNID identifies the VXLAN segment but does not manage isolation directly. The switch fabric and host switch play roles in forwarding but do not enforce Layer 2 isolation in the VXLAN context.
