Network Design

A network consultant must design a highly available interconnection from a clustered Cisco UCS Fabric Interconnect to two upstream Layer 2 switches. The Ethernet interconnection must use all redundant links and must not affect 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
Explanation

Cisco UCS Fabric Interconnect end-host mode does not run STP and presents its uplinks as host-facing connections to the upstream network, so it avoids expanding the STP domain. Dual uplinks distributed evenly across the two upstream switches provide use of the available redundant links and uplink resilience.
