VMware Certified Professional - Data Center Virtualization (VCP-DCV) Practice Exam

Under CPU contention in a DRS cluster, which virtual machine receives more CPU resources?

1. Prod-VM1 receives four times the CPU resources than Test-VM1.

2. Prod-VM1 will always have more CPU resources than all other virtual machines.

3. Test-VM2 will always have less CPU resources than all other virtual machines.

4. Test-VM1 will receive 25% of the total CPU resources.

The correct answer is: Prod-VM1 receives four times the CPU resources than Test-VM1.

The correct assertion regarding CPU contention in a Distributed Resource Scheduler (DRS) cluster revolves around the concept of resource allocation, particularly in scenarios where virtual machines (VMs) have specific resource shares defined. In a typical DRS environment, resources are allocated based on the configured shares, and VMs with higher shares receive a greater proportion of available resources when contention occurs. The statement that Prod-VM1 receives four times the CPU resources compared to Test-VM1 suggests that there is a significant disparity in the resource shares assigned to these two virtual machines. When there is competition for CPU resources among VMs, DRS prioritizes those with higher shares, thereby ensuring they receive a larger portion of CPU cycles. This scenario indicates that the configuration of shares was designed with the intention of favoring Prod-VM1, likely because it is associated with critical workloads needing higher resource availability. Therefore, under conditions of CPU contention, it is reasonable to expect that Prod-VM1 will obtain four times more CPU resources than Test-VM1, as per its allocated shares. The other scenarios described do not reflect the flexibility and dynamic allocation capabilities intrinsic to DRS. The rigidity of the other options would imply strict and unchangeable resource distributions that don't align
