Which three statements regarding Network I/O Control (NIOC) are accurate? (Choose three.)
A.
NIOC enforces traffic bandwidth limits on the overall vDS set of dvUplinks.
B.
NIOC limits maximum throughput control on connected virtual machines.
C.
Load based teaming efficiently uses a vDS set of dvUplinks for network capacity.
D.
Isolation provides priority to any one traffic flow.
E.
Relative shares fairly allocates available bandwidth among multiple flows.

NIOC provides users with the following features:
Isolation: Ensure traffic isolation so that a given flow will never be allowed to dominate over others, preventing drops and undesired jitter
Shares: Allow flexible networking capacity partitioning to help users to deal with over commitment when flows compete aggressively for the same resources
Limits: Enforce traffic bandwidth limit on the overall VDS set of dvUplinks
Load-Based Teaming: Efficiently use a VDS set of dvUplinks for networking capacity
IEEE 802.1p tagging: Tag packets going out of the vSphere host for proper handling by physical network resources.
NIOC classifies traffic into a number of predefined resource pools:
vMotion
iSCSI
FT logging
Management
NFS (Network File System)
Virtual machine traffic
vSphere Replication traffic
User Defined

Do not confuse with question 1314.
Isolation des NOT provide priority to any one traffic flow; it lmits the flow

Thanks Chris, your link is spot on mate.
