Answer: E

Explanation:

VMware vCenter is

• optional when deploying on UC on UCS Tested Reference Configuration hardware

• mandatory when deploying on UC on UCS Specs-based and Third-party Server Specs-based hardware .

• vCenter Statistics Level 4 logging is mandatory so that Cisco TAC is able to provide effective support.

• Click here for how to configure VMware vCenter to capture these logs. If not configured by default, Cisco TAC may request enabling these settings in order to provide effective support.

• Also note that enablement of specific VMware vSphere management features may require vCenter and/or a higher feature Edition of vSphere ESXi.

• Cisco Collaboration does not require its own dedicated vCenter.

• Note that when VMware vCenter is not required and is not used, then VMware vSphere ESXi’s default management interface is its free/included VMware vSphere Client (formerly branded VI Client).
