Suppose you have 10000 Virtual Machines across 2 Datacenters, with approximately 5000 Virtual Machines in each Datacenter. What is the minimum number of vCenter installations and vNetwork Distributed Switches required to support this configuration (Choose Two)?
A.
1 vCenter Server
B.
2 vNetwork Distributed Switches per Datacenter
C.
2 vCenter Servers
D.
1 vNetwork Distributed Switch per Datacenter
Explanation:
Configuration Maximums VMware vSphere 4.1 page 5, 6.
http://www.vmware.com/pdf/vsphere4/r41/vsp_41_config_max.pdf+ Total virtual network switch ports per host (vDS and vSS ports) 4096 – B
+ Powered on virtual machines per vCenter Server 10000 – A

+ Base on vsp_40_config_max.pdf, answers are B & C.
+ Based on vsp_41_config_max.pdf, answers are A & B.
Finally, answers for this question should be A & B.

I think the answers should be A & D
No where in the question does it mention “HOSTS”…it only refers to VMs, so here is what the document says:
P. 5 – Ports per distributed switch – 20,000
P. 6 – Powered on virtual machines per vCenter Server – 10,000
1 distributed switch per datacenter should be more than enough to handle 5000 VMs per datacenter even if each VM used 3 ports…that’s a total of 40,000 ports between the 2 datacenters (the question isn’t talking about ports per host).
