Question #5

Following a recent acquisition, the architect learns that both companies use vSphere on-premise and will need to combine the data centers into one. The acquired company’s licenses will not be renewed for cost-savings related to the acquisition. All consumed vSphere licenses must have active support to support line-of-business operations. The merged environment must maintain 25% spare capacity. The architect has a small budget remaining unallocated for hardware.

The architect has calculated that the current vSphere environment can absorb the acquired company’s virtual machines but the cluster will run at 90% memory utilization and at 50% CPU utilization.

  • A . Migrate the acquired company’s virtual machines into the vSphere environment as it will currently fit.
  • B . Use the current budget to add memory to the cluster to increase each ESXi host’s capacity and add the new virtual machines.
  • C . Purchase extra hosts to add to the cluster in anticipation of adding the acquired company’s virtual machines.
  • D . Purchase new licenses for some of the acquired company’s ESXi hosts and add them to the cluster to hold the acquired company’s virtual machines.
