Dell EMC Associate – PowerStore Solutions — Question 8

What feature of the Cisco UCS compute platform in a Dell EMC VxBlock system helps to provide application high availability?

Answer options

• A. Fabric Interconnects support the addition of expansion modules
• B. Redundant components ensure there is no single point of failure
• C. Each of the Fabric Extenders in a chassis connects to both Fabric Interconnects
• D. Each blade server has a dedicated power supply

Correct answer: C

Explanation

The correct answer is C because having each Fabric Extender connect to both Fabric Interconnects provides redundancy and ensures continuous connectivity, thereby enhancing application availability. Options A and D, while they describe features of the system, do not specifically address the high availability aspect. Option B, although relevant to redundancy, does not detail the specific mechanism within the UCS architecture that supports high availability as effectively as C does.
