ESXi hosts with 10Gbps network cards are attached to a distributed switch. The administrator has upgraded to
NIOC3 and wants to allow vMotion traffic to use as much bandwidth as possible but must ensure that other
services always have sufficient bandwidth.
How can this be done?
A.
Configure shares on the distributed switch for the vMotion traffic type.
B.
Configure limits on the distributed switch on the on vMotion traffic type.
C.
Associate vMotion traffic with a network resource pool and use CoS tagging.
D.
Set shares on user-defined network resource pool and associate it with vMotion traffic.
A – OK
NIOC3
Bandwidth Allocation for System Traffic
You can configure Network I/O Control to allocate certain amount of bandwidth for traffic generated by vSphere Fault Tolerance, iSCSI storage, vSphere vMotion, and so on.

Why not B, as you have to ensure other types of traffic have enough BW to go through, and with share you just set priority? (IMO it is a mix of A and B that would reach this goal, high share and limit, but we must pick one)
A limit is a cap. It will not ensure “enough” resources, but it will make sure that it cannot go above the defined limit.
I believe the answer is A
Exactly, so you limit vMotion traffic to let the other types of traffic have sufficient BW. As I said, I would configure Limit and share to vmotion so it would have priority over others but with limitations, but we have to pick one… =\
A
A limit is an upper bound or cap, but a share value is a “relative importance”…
So shares can raise the importance of vMotion traffic against other traffic types and if done correctly it wouldn’t starve the other services. The question doesn’t say it wants to set an upper bound. It wants to allow “as much as possible” to vMotion. Shares are only enforced when there is resource contention so if there is no contention then vMotion can have it all. That wouldn’t be possible with a limit.
I can see where you come from, but I’m sticking with A.
I also think it’s A. I tested it myself and I cannot see a use case were answer D would be the right thing to do here.
A
Agree with A

A. six hosts
B. three hosts
C. four hosts
D. five hosts
Answer: C
NEW QUESTION 8
Which three TCP/IP stacks are built in at the VMkernel level in vSphere 6.x? (Choose three.)
A. Fault Tolerance

C. Provisioning
D. Management
E. Default
Answer: ABC
NEW QUESTION 9
In vSphere 6.5, a virtual machine is thinly-provisioned on a VMFS6 datastore. The administrator deleted a large file within the guest OS. The freed blocks in the datastore are no longer needed by the VM. Which feature in vSphere 6.5 allows the backing storage to automatically reclaim the freed blocks?
A. ATS
B. Defrag
C. UNMAP
D. Auto Reclaim
Answer: C
Explanation:
VAAI UNMAP was introduced in vSphere 5.0 to allow the ESXi host to inform the backing storage that files or VMs had be moved or deleted from a Thin Provisioned VMFS datastore. This allowed the backing storage to reclaim the freed blocks. There was no way of doing this previously, resulting in many customers with a considerable amount of stranded space on their Thin Provisioned VMFS datastores.
NEW QUESTION 10
A new virtual machine cannot reach its default gateway.
– The vSphere administrator checks that the virtual machine’s vmnic is connected to the correct portgroup, and that the portgroup is on the correct virtual switch.
– This is the only virtual machine on this portgroup.
– Other virtual machines that are on the host and connected to the same Distributed switch are running as normal.
– The Distributed Switch has only one uplink.
Which could be the cause of this issue?
A. Block All Ports has been selected on the Distributed Switch.
B. The wrong VLAN ID has been added to the portgroup.
C. The VLAN has not been configured in virtual machine hardware settings.
D. The physical adapter is down.
Answer: D
NEW QUESTION 11
Which two requirements must be met before enabling vSphere HA Application Monitoring for a virtual machine? (Choose two.)
A. VMware Tools must be installed on the VM.
B. The vSphere Guest SDK must be installed on the VMs needing Application Monitoring.
C. Application Monitoring requires that vCenter Server is linked to a working instance of vRealize Operations Manager and the End Points Operations agent has been installed on the guest.
D. Application Monitoring is only supported on Linux operating systems.
E. Application Monitoring is only supported on Windows operating systems.
Answer: AE
