Designing Cisco Data Center Infrastructure (DCID) — Question 142

An engineer must design a Cisco SAN environment between two data centers for backup and replication purposes. The data centers are separated by 510 kilometers and are interconnected via a 16-Gbps WAN/MAN link. Which topology must be used to interconnect the data centers?

Answer options

• A. multi-switch
• B. native Fibre Channel SAN extension
• C. large-scale edge-core-edge
• D. unified fabric

Correct answer: D

Explanation

The correct answer is D, unified fabric, as it allows for the integration of storage and data traffic over the same network infrastructure, which is essential for long-distance data center connectivity. The other options, while relevant to SAN configurations, do not optimize for the specific requirements of backup and replication over a WAN/MAN link.
