A vSphere Administrator notices that sometimes they receive poor network throughput for multiple port groups
that reside on a vSwitch with multiple physical uplinks (vmnics). The configuration on the ESXi host is identical
to other hosts that are working properly in the same cluster.What should be done next?
A.
Restart Management agents in ESXi Using Direct Console User Interface (DCUI).
B.
Add additional port groups to the vSwitch.
C.
Alter the failover order of the vmnics until a bad vmnic is found.
D.
Add additional resources to the virtual machines that are powered on.

D is probable answer.
Network problems can have several causes:
– Virtual machine network resource shares are too few.
– Network packet size is too large, which results in high network latency
– Network packet size is too small, which increases the demand for the CPU resources needed for processing each packet. Host CPU, or possibly virtual machine CPU, resources are not enough to handle the load.
