Explanation

QoS must be enabled in all Cisco UCS VMware-based UCCE deployments - both C-Series (rack servers) and B-Series (blade servers) - because virtual environments cannot natively prioritize traffic the way dedicated hardware can, making QoS essential for call quality and signaling reliability even over a dedicated WAN circuit. Options B and D are correct because they accurately reflect Cisco's design guidance that VMware-based UCCE requires QoS on both UCS form factors.

Why the distractors are wrong:

• A - Incorrect because a dedicated WAN circuit doesn't eliminate the need for QoS; virtualization introduces traffic contention that QoS must manage.
• C - Directly contradicts Cisco's guidance; B-Series also requires QoS enabled, not disabled.
• E - "Only for third-party" is false; QoS applies to Cisco UCS environments as well, making the word "only" the trap.

Memory tip: Think "VMware = QoS always ON" - whenever UCCE runs in a virtualized (VMware) environment, regardless of UCS series letter (B or C), QoS must be enabled. The only variable is the platform vendor, but Cisco's own UCS platforms follow the same rule.
