Refer to the exhibit. Which option describes Cisco Unified CCE on the UCS B Fabric Interconnection pair to the upstream network connectivity?

The correct answer is B. Have a cross-connect links scheme from the UCS B FI pair to the upstream Layer 2 switches as. Option B is correct because Cisco Unified CCE requires a cross-connect links scheme, where each Fabric Interconnect (FI-A and FI-B) connects to both upstream Layer 2 switches. This creates an "X" pattern that ensures full redundancy - if one upstream switch fails, both FIs…

Explanation

Option B is correct because Cisco Unified CCE requires a cross-connect links scheme, where each Fabric Interconnect (FI-A and FI-B) connects to both upstream Layer 2 switches. This creates an "X" pattern that ensures full redundancy - if one upstream switch fails, both FIs still maintain network connectivity through the surviving switch, which is essential for the high availability demands of a contact center environment.

Option A is wrong because the straight-links scheme ties FI-A exclusively to one upstream switch and FI-B to the other, creating a scenario where a single upstream switch failure can isolate one entire FI from the network - an unacceptable single point of failure for CCE.

Option C is wrong because it implies either design could work (with one being preferred); in reality, the straight-links scheme is not a validated option for Unified CCE at all.

Option D is wrong because you cannot mix or combine both schemes simultaneously - only one topology is deployed at a time, and the cross-connect is the required one.

Memory tip: Think "Cross-connect = Cisco CCE." The double-C in CCE reminds you that both FIs must cross-connect to both switches - never one-to-one straight links.
