Designing Cisco Data Center Infrastructure (DCID) — Question 194
A network consultant must design a high availability interconnection of a clustered Cisco UCS Fabric Interconnect toward two upstream Layer 2 switches. The Ethernet interconnection must use all redundant links and have no impact on the STP domain size.
Which connectivity solution must be used?
Answer options
- A. Cisco UCS Fabric Interconnect in switch mode with dual uplinks distributed evenly to the upstream switches
- B. Cisco UCS Fabric Interconnect in switch mode with a single uplink toward each upstream switch to eliminate any change to the STP domain size
- C. Cisco UCS Fabric Interconnect in end host mode with a single uplink toward each upstream switch to eliminate any change to the STP domain size
- D. Cisco UCS Fabric Interconnect in end host mode with dual uplinks distributed evenly to the upstream switches
Correct answer: D
Explanation
The correct answer is D because using the Cisco UCS Fabric Interconnect in end host mode with dual uplinks allows for redundancy while keeping the STP domain size unchanged. Options A and B do not satisfy the requirement for redundancy, and option C lacks the necessary dual uplinks to ensure high availability.
