VMware 3V0-21.23 Exam - Topic 2 Question 19 Discussion

A company has the requirement of ensuring that business-critical applications have the necessary network bandwidth to function optimally and maintain a consistent quality of service (QoS).Which statement would be included in the logical design to support this requirement?
D) A distributed virtual switch will be created and Network I/O Control will be enabled.
A) The network infrastructure must ensure secure communications and efficiently use available bandwidth.
B) Network resource pool named 'bca-pool-02' is given a reservation quota of 5Gbit/sec.
C) The distributed switch will use a minimum of 25Gbps Ethernet.

[All 3V0-21.23 Questions]

A company has the requirement of ensuring that business-critical applications have the necessary network bandwidth to function optimally and maintain a consistent quality of service (QoS).

Which statement would be included in the logical design to support this requirement?

Show Suggested Answer Hide Answer
Suggested Answer: D

Network I/O Control (NIOC) is a key feature available with distributed virtual switches (vDS) that allows administrators to prioritize and allocate bandwidth to specific network traffic types. It ensures that business-critical applications receive the necessary bandwidth and maintain a consistent quality of service (QoS). This solution meets the requirement to ensure optimal network bandwidth allocation and service consistency.
