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 4.0 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): 4500Since, 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.
Are you sure about the 2 vDSs per datacenter? If the vDS has 6000 ports, the 5000 VMs should only require 1 vDS. I’m not sure the 4096 (4088) limit applies since we don’t know how many hosts.
