The correct answer is B. The virtual machine has insufficient resources for the environment size. For a vCenter 6.x Large environment with 1,000 ESXi hosts and 10,000 VMs using an embedded PSC, 8 vCPUs and 16 GB RAM fall well below the minimum required hardware resources.

Section 4 – Upgrade vSphere 6.x to vSphere 6.x

Question

An administrator wants to upgrade to vCenter Server 6.x. The vCenter Server:

  • Is hosted on a virtual machine server running Microsoft Windows

Server 2008 R2, with 8 vCPUs and 16GB RAM.

  • Will have an embedded Platform Services Controller.
  • Hosts a Large Environment with 1,000 ESXi hosts and 10,000 Virtual

Machines. Why does the vCenter Server not meet the minimum requirements?

Options

  • AWindows Server 2008 R2 is not a supported Operating System for vCenter Server.
  • BThe virtual machine has insufficient resources for the environment size.
  • CThe environment is too large to be managed by a single vCenter Server.
  • DThe Platform Services Controller must be changed to an External deployment.

Why each option

For a vCenter 6.x Large environment with 1,000 ESXi hosts and 10,000 VMs using an embedded PSC, 8 vCPUs and 16 GB RAM fall well below the minimum required hardware resources.

AWindows Server 2008 R2 is not a supported Operating System for vCenter Server.

Windows Server 2008 R2 is a supported operating system for hosting vCenter Server 6.x, so the OS choice is not the disqualifying factor in this scenario.

BThe virtual machine has insufficient resources for the environment size.Correct

vCenter Server 6.x with an embedded Platform Services Controller configured for a Large deployment supporting up to 1,000 hosts and 10,000 VMs requires a minimum of 24 vCPUs and 48 GB RAM; the described configuration of 8 vCPUs and 16 GB RAM meets only the Small environment requirements and would cause severe performance degradation or instability at scale.

CThe environment is too large to be managed by a single vCenter Server.

A single vCenter Server 6.x instance officially supports up to 1,000 ESXi hosts and 10,000 VMs, meaning the described environment size is within the documented scale limits and is not the problem.

DThe Platform Services Controller must be changed to an External deployment.

An embedded Platform Services Controller is a valid and fully supported deployment topology for large environments in vCenter 6.x, so switching to an external PSC is not required to meet the deployment requirements.
