A vSphere 5 implementation consists of a fully automated DRS cluster with two ESXi 5.x hosts
with the following vSphere Standard Switch configuration:
1. Switch A. three vmnics, one port group named sFTP-PG
2. Switch B. two vmnic, one port group named Web-PG
3. All vmnics are trunked to the same physical switch.
DRS has been configured with an anti-affinity rule for all virtual machines in the Web-PG so that
no more than half of the virtual machines run on any given host. The virtual machines on WebPG
are experiencing significant network latency. The network team has determined that a
performance bottleneck is occurring at the ESXi host level.
Which solution will require the least amount of administrative work and the least amount of service
interruption?
A.
Migrate Web-PG to Switch A and sFTP-PG to Switch B on each host
B.
Move a vmnic from Switch A to Switch B on each host
C.
Convert the three Switch Bs to a single vSphere Distributed Switch
D.
Use vMotion to redistribute some of the VMs in Web-PG to a different ESXi host
Explanation:
Let us examine this is a problem with resource contention on a NIC on a host. VDS WILL NOT fix
the problem because dvuplinks are the same as uplinks on the ESX host experiencing a
problem.VMotion should not be a solution, DRS already has VMotion and knows where to place
VMs using defined rules.
