Which failure scenario in the Cisco Unified Contact Center Enterprise solution stops all processing and routing of contact center calls?

Question

Options

• AICM Call Router Side A fails at the same time that ICM Logger Side A fails.
• BICM Call Router Side A fails at the same time that ICM Logger Side B fails.
• CICM Call Router Side B fails at the same time that ICM Logger Side A fails.
• DICM Call Router Side B fails at the same time that ICM Logger Side B fails.
• EICM Call Router Side A fails at the same time that ICM Call Router Side B fails.
• FICM Logger Side A fails at the same time that ICM Logger Side B fails.

Explanation

Option E is correct because the ICM Call Router is the active decision-making component responsible for executing routing scripts and directing all contact center calls - it is the true "brain" of the UCCE solution. When both Side A and Side B of the Call Router fail simultaneously, there is no remaining routing engine to process calls, causing a complete outage.

Why the distractors are wrong: Options A, B, C, and D each involve only one Call Router side failing (alongside a Logger). Since the Call Router is deployed in a duplex (A/B) architecture, the surviving side automatically takes over routing - no outage occurs. Option F (both Loggers failing) is tempting but wrong: Loggers store historical and configuration data, but they do not perform real-time call routing; the Call Routers can continue operating without them, though data recording would be impacted.

Memory tip: Think of it this way - Routers route, Loggers log. You can lose your memory (both Loggers) and still function; but if you lose your entire brain (both Call Routers), everything stops. The only "total failure" scenario is when both Call Router sides go down together.
