Designing Cisco Data Center Infrastructure (DCID) — Question 134

An engineer must design Layer 2 connectivity for a subnet between two data centers. The engineer must ensure seamless host mobility and optimal first-hop routing. Which attribute must be synchronized across all data centers to achieve this goal?

Answer options

• A. NX-OS version
• B. multicast group
• C. DCNM to manage both fabrics
• D. anycast gateway MAC

Correct answer: D

Explanation

The correct answer is D, as synchronizing the anycast gateway MAC facilitates seamless host mobility by allowing devices to use the same gateway regardless of their location in the data centers. Options A, B, and C do not directly impact host mobility and first-hop routing in the same way that the anycast gateway MAC does.
