Designing Cisco Data Center Infrastructure (DCID) — Question 57
A network engineer must design a data center network with four Cisco Nexus 7706 switches. The switches will be installed in primary and secondary data centers in vPC domains. The two data centers must be connected via Layer 2 links and provide the maximum throughput, redundancy, and avoid port-blocking spanning-tree design.
Which deployment model meets these requirements?
Answer options
- A. dual-sided single vPC
- B. single-sided dual vPC
- C. dual-sided dual vPC
- D. single-sided single vPC
Correct answer: C
Explanation
The correct answer is C, as a dual-sided dual vPC configuration allows both data centers to utilize multiple active paths for traffic, maximizing throughput and redundancy while avoiding spanning-tree port blocking. Options A and D do not provide sufficient redundancy and could lead to port blocking, while option B does not utilize the full capabilities of both data centers effectively.
