Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 510

Which solution do IaaS service providers use to extend a Layer 2 segment across a Layer 3 network?

Answer options

• A. VXLAN
• B. VTEP
• C. VRF
• D. VLAN

Correct answer: A

Explanation

VXLAN is designed specifically to extend Layer 2 segments over Layer 3 networks, allowing for greater scalability and flexibility in data center environments. VTEP is a component used in conjunction with VXLAN for encapsulating and decapsulating packets, while VRF is for routing purposes and VLAN is limited to Layer 2 segments without Layer 3 capabilities.
