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?
A.
Windows Server 2008 R2 is not a supported Operating System for vCenter Server.
B.
The virtual machine has insufficient resources for the environment size.
C.
The environment is too large to be managed by a single vCenter Server.
D.
The Platform Services Controller must be changed to an External deployment.

Explanation/Reference:
B is correct:

It’s low on CPU and Memory
Pg 30 – vCenter Server for Windows Hardware Requirements
tiny – 10h / 100vm – 2 cpu 8G RAM
Sm – 100h / 1K vm – 4 cpu 16G RAM
Md – 400h / 4K vm – 8 cpu 24G RAM
Lg – 1K h / 10,000vm – 16 cpu 32G RAM

It requires a minimum of 32GB to manage a Large Environment with 1,000 ESXi hosts and 10,000 Virtual Machines.

Why not D? Embedded PSC supports a max of 5 hosts?
Per https://pubs.vmware.com/vsphere-60/index.jsp?topic=%2Fcom.vmware.vsphere.upgrade.doc%2FGUID-D2121DC5-1FC8-48DC-A4BA-C3FD72D0BE77.html Embedded can be used. No maximum is listed in the Configuration Maximum guide for embedded PSC’s. Though, in the vSphere Installation and Setup Guide, installing an embedded PSC is “suitable for small-scale environments.”

You could see in the notes above it..
vCenter Server with an Embedded or External Platform Services Controller for a Large Environment (up to 1,000 Hosts, 10,000 Virtual Machines)
