Designing Cisco Network Service Architectures (ARCH, legacy) — Question 52

An engineer is implementing VXLAN to extend layer 2 traffic at three geographically diverse data centers. Which feature is required at each data center to extend this traffic?

Answer options

• A. VTEP
• B. VRRP
• C. VLSM
• D. VPLS

Correct answer: D

Explanation

The correct answer is VPLS, as it is specifically designed to extend Layer 2 networks over a wide area network (WAN), which is necessary for this scenario. VTEP is involved in VXLAN but is not the feature required to extend the traffic itself. VRRP is used for redundancy and failover, and VLSM deals with IP address allocation, neither of which are pertinent to extending Layer 2 traffic.
