Designing Cisco Data Center Infrastructure (DCID) — Question 4

What are two reasons to select OTV as the DCI solution to connect multisite topologies? (Choose two.)

Answer options

• A. It propagates hosts reachability without support of traffic flooding.
• B. Layer 3 failures do not propagate beyond the OTV edge device.
• C. It extends the spanning tree between data centers.
• D. It is an open standard.
• E. It constrains HSRP hello messages to each data center.

Correct answer: A, E

Explanation

The correct answers are A and E because OTV efficiently propagates host reachability without flooding traffic, making it a scalable solution. Additionally, E is correct as it ensures that HSRP hello messages are limited to their respective data centers, reducing unnecessary traffic. Options B, C, and D are incorrect as they do not accurately describe the benefits of OTV in this context.
