An administrator wants to ensure that any virtual machine added to a certain port group always has sufficient
network resources. Network I/O Control version 3 has been enabled on the Distributed Switch.
Which three steps will achieve this objective? (Choose three.)
A.
Reserve bandwidth for virtual machine system traffic on the Distributed Switch Port Group.
B.
Edit the virtual machine’s Resource settings and set a reservation for virtual machine system traffic.
C.
Create a Network Resource Pool on the Distributed Switch and set a reservation quota.
D.
Reserve bandwidth for virtual machine system traffic on the Distributed Switch.
E.
Add the Network Resource Pool on the Distributed Switch Port Group.

To limit via port group you must create a network resource pool and add the VDS port group to it. To create a quota in the network resource pool you need a reservation at the VDS level first.

A network resource pool provides a reservation quota to virtual machines. The quota represents a portion of the bandwidth that is reserved for virtual machine system traffic on the physical adapters connected to the distributed switch. You can set aside bandwidth from the quota for the virtual machines that are associated with the pool. (C correct)
Verify that the virtual machine system traffic has a configured bandwidth reservation.(D correct)
Add one or more distributed port groups to the network resource pool so that you can allocate bandwidth to individual virtual machines from the quota of the pool.(E correct)

Hi All,
I am planing to write VCP 6.5 so I got one question is this valid answers which are turning in green.
If anyone has valid dump can I get it on email id.

Any of the methods noted under A, C and E are correct indeed.
B and D are about system traffic that is handled thru vmkernel ports, i.e. not really VM user-facing traffic.

Sorry, need to correct myself… this is not about system traffic vs. non-system.
B is wrong because network bandwidth reservations are defined on the pool level, not on the VM level. VM can be associated with a network resource pool.
D is wrong as reservations are done per port group, not for the entire DVS.

This is one of the semantics type of questions… If the emphasis is on where network resource pools can be created (at the DVS level and not on the dPortGroup), then A and E are off.
‘B’ is not suitable either as the question asks about a scalable solution that would “ensure that any virtual machine added to a certain port group…”, i.e. setting reservations individually for each VM is not practical under this context.
That leaves only C and D as correct answers.
Now, having to choose what would be the least incorrect of the remaining options, ‘E’ is the one to pick, especially if by adding an RP to dPG they mean association of dPG with a network pool previously defined on the DVS level.
