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.
Correct Answer: ACE
Explanation/Reference:
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.
