Exam 300-610 topic 1 question 115 discussion

Actual exam question from Cisco's 300-610

Question #: 115
Topic #: 1

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?

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

Selected Answer: D

To design a high-availability interconnection for a clustered Cisco UCS Fabric Interconnect (FI) toward two upstream Layer 2 switches, use a redundant port channel configuration. This ensures all links are utilized and avoids impact on the STP domain size. Specifically, configure each upstream switch port channel to each FI, and configure the FIs in End-Host mode to allow direct connectivity to the upstream switches without STP involvement.
