An administrator is enabling Network I/O Control (NIOC) on a vSphere Distributed Switch. Which types of network traffic can be prioritized with NIOC by default?
(Choose three.)
A. FCP Traffic
B. NFS Traffic
C. Virtual Machine Traffic By Virtual Machine
D. iSCSI Traffic
E. vSphere Replication (VR) Traffic
Correct Answer: BDE
Explanation/Reference:
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
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.
