VMware vSphere 6 Advanced Design (VCAP6-DCV Design) — Question 43

A database administrator is operating a virtual machine (VM) configured with 16 vCPU and 64GB of RAM. A recent performance audit has indicated that this virtual machine is oversized and is using less than 60% of its configured CPU and memory capacity.
✑ The ESXi host that contains this VM has 2 physical processors with 10 cores per processor, and 128GB of RAM.
✑ This physical host's architecture is split into two equal NUMA nodes.
Which vCPU and RAM configuration for the VM allows for the most resources, but also provides the performance benefit of local NUMA access?

Answer options

Correct answer: B

Explanation

The correct answer is B because it provides a lower number of vCPUs and RAM that still allows the VM to operate efficiently without oversizing. This configuration ensures that the VM can take advantage of local NUMA access, which is critical for performance. The other options are either too high in resource allocation or do not utilize the NUMA architecture effectively.
