Designing Cisco Data Center Infrastructure (DCID) — Question 79

A Cisco UCS chassis with several blade servers, a pair of IOMs, and a pair of Cisco UCS Fabric Interconnects are installed in a data center.

Which two high-availability architectures are recommended between the IOMs and fabric interconnects? (Choose two.)

Answer options

• A. One, two, four and eight links are supported to be used between each IOM and fabric interconnect.
• B. IOM A is connected to the fabric interconnect that is acting as fabric A, and IOM B is connected to the fabric interconnect that is acting as fabric B.
• C. Any combination of one to eight links is supported to be used between each IOM and fabric interconnect.
• D. The IOMs are connected with multiple straight and cross-connect links toward a pair of nonclustered fabric interconnects.
• E. Straight and cross-connect links should be used between the IOMs and fabric interconnects to offer higher availability.

Correct answer: A, B

Explanation

The correct answers, A and B, specify the supported configurations for achieving high availability between IOMs and fabric interconnects. Option A accurately describes the link configurations, while Option B outlines the proper connection method between IOMs and fabric interconnects. The other options either misrepresent the configurations or do not necessarily enhance availability.
