The correct answer is A. Configure shares on the distributed switch for the vMotion traffic type. NIOC3 shares allow vMotion to consume available bandwidth proportionally while guaranteeing minimum bandwidth for all other system traffic types on the distributed switch.
Question
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?
Options
- AConfigure shares on the distributed switch for the vMotion traffic type.
- BConfigure limits on the distributed switch on the on vMotion traffic type.
- CAssociate vMotion traffic with a network resource pool and use CoS tagging.
- DSet shares on user-defined network resource pool and associate it with vMotion traffic.

Why each option
NIOC3 shares allow vMotion to consume available bandwidth proportionally while guaranteeing minimum bandwidth for all other system traffic types on the distributed switch.
In NIOC3, configuring higher shares for the vMotion system traffic type on the distributed switch allows vMotion to consume as much available bandwidth as possible during contention, while other traffic types retain their own share-based minimums - achieving maximum vMotion throughput without starving other services.
Configuring a limit on vMotion would cap its maximum usable bandwidth, which directly contradicts the requirement to allow vMotion to use as much bandwidth as possible.
CoS tagging marks traffic for prioritization at the physical network layer but does not control how NIOC3 internally allocates bandwidth between vSphere system traffic types on the distributed switch.
User-defined network resource pools in NIOC3 are designed for VM traffic, not built-in system traffic types like vMotion, so vMotion cannot be assigned to a user-defined pool.
Concept tested: NIOC3 shares for vSphere system traffic types
