The correct answer is A. Configure shares on the distributed switch for the vMotion traffic type.. NIOC3 shares allow vMotion to consume available bandwidth dynamically while protecting other traffic types during contention periods.
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 dynamically while protecting other traffic types during contention periods.
Configuring shares on a distributed switch for vMotion defines its proportional weight relative to other traffic types. During contention, each traffic type receives bandwidth proportional to its shares, ensuring other services always get their guaranteed slice. When no contention exists, vMotion can freely use all available bandwidth up to line rate.
Limits cap the absolute maximum bandwidth vMotion can use, which directly prevents it from using as much bandwidth as possible - the opposite of the requirement.
CoS tagging marks packets for QoS priority treatment at external switches but does not control bandwidth allocation within the distributed switch itself.
User-defined network resource pools in NIOC3 are intended for virtual machine port group traffic, not system traffic types like vMotion; system traffic shares are set directly on the switch.
Concept tested: NIOC3 shares for system traffic types
