Designing Cisco Data Center Infrastructure (DCID) — Question 116
A network architect designs a high-availability architecture for the Cisco UCS Fabric Interconnects that are installed in a data center. The architecture must support clustering and redundancy.
Which architecture meets these requirements?
Answer options
- A. dual connections from port L1 to L1 and one connection from port L1 to L1 with twinax cables
- B. dual connections from port L1 to L2 and one connection from port L2 to L1 with twinax cables
- C. dual connections from port L1 to L2 and one connection from port L2 to L1 with Ethernet cables
- D. dual connections from port L1 to L1 and one connection from port L2 to L2 with Ethernet cables
Correct answer: D
Explanation
The correct answer is D because it provides dual connections from port L1 to L1, ensuring redundancy, and a connection from port L2 to L2, which supports clustering. Options A and B do not provide the necessary redundancy across the ports, while option C also fails to meet the requirement for redundancy in the specific layout needed for high availability.
