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 if all virtual machines were powered on (Choose Two)?
A.
1 vNetwork Distributed Switch per Datacenter
B.
4 32-bit Windows based vCenter Servers in Linked Mode
C.
2 vNetwork Distributed Switches per Datacenter
D.
4 64-bit Windows based vCenter Servers in Linked Mode
Explanation:
Configuration Maximums VMware vSphere 4.0 and vSphere 4.0 Update 1, age 6, 7.
Table 5. Networking Maximums
Total virtual network switch ports per host (vDS and vSS ports) 4096
Since there are approximately 5000 VMs per Datacenter, 2 vNetwork Distributed Switches per Datacenter are required, hence C.
Table 7. vCenter Server Maximums
Powered?on virtual machines (32?bit OS server) 2000 Registered virtual machines (32?bit OS server) 3000 Powered?on virtual machines (64?bit OS server) 3000 Registered virtual machines (64?bit OS server) 4500
Since, the question states ‘What is the minimum number of vCenter installations and vNetwork Distributed Switches required to support this configuration if all virtual machines were powered on’, and there are 10000 VMs, either 4 vCenter 64?bit OS servers or 5 vCenter 32?bit OS servers are required. Therefore D is required.
