Which two Network I/O Control bandwidth allocation parameters are applicable? (Choose two.)

The correct answer is A. Reservation D. Share. vSphere Network I/O Control (NIOC) uses Shares and Reservation as its two bandwidth allocation parameters for network resource pools.

Why each option

vSphere Network I/O Control (NIOC) uses Shares and Reservation as its two bandwidth allocation parameters for network resource pools.

AReservationCorrect

Reservation guarantees a minimum amount of bandwidth (in Mbps) for a network resource pool, ensuring critical traffic types always have sufficient capacity even under contention.

BQuota

Quota is not a valid NIOC parameter; the correct term for capping maximum bandwidth is Limit, not Quota.

CLevel

Level is not a standard NIOC bandwidth allocation parameter; the three valid NIOC parameters are Shares, Limit, and Reservation.

DShareCorrect

Shares assign a relative weight to each network resource pool so that when uplink bandwidth is saturated, traffic is proportionally distributed based on share values among competing workloads.
