Designing Cisco Data Center Infrastructure (DCID) — Question 65

An engineer must design a disaster recovery solution for a Cisco ACI Multi-Site network. One requirement is that the applications must have seamless IP addressing across sites. The solution must also be highly resilient and support Layer 2 adjacency. Which design meets these requirements?

Answer options

• A. localized bridge domain, subnet, and EPG stretched Layer 2 broadcast domain
• B. stretched bridge domain with local subnet stretched Layer 2 broadcast domain
• C. localized bridge domain with local subnet localized Layer 2 broadcast flooding
• D. stretched bridge domain, subnet, and EPG localized Layer 2 broadcast flooding

Correct answer: D

Explanation

The correct answer is D because it provides a stretched bridge domain, which ensures seamless IP addressing across sites and supports Layer 2 adjacency. Options A and C do not meet the requirement for a stretched Layer 2 broadcast domain, while option B lacks the necessary Layer 2 adjacency across sites.
