Designing Cisco Data Center Infrastructure (DCID) — Question 23

What is an advantage of using OTV as compared to VPLS for data center redundancy?

Answer options

• A. prevents loops on point-to-point links
• B. provides head-end replication
• C. uses a proactive MAC advertisement
• D. provides full-mesh connectivity

Correct answer: A

Explanation

The correct answer is A because OTV effectively prevents loops on point-to-point links, which is crucial for maintaining network stability. In contrast, VPLS does not inherently prevent such loops, making it less advantageous in this regard. While the other options may describe features of OTV or VPLS, they do not specifically address the redundancy advantage of OTV over VPLS.
