2V0-21.23 Question 70
Single answerYour organization has recently deployed Network I/O Control (NIOC) on a distributed switch in a VMware vSphere environment. During a performance review, you notice that critical virtual machine traffic is being affected during periods of bandwidth contention. Which action should you take to ensure critical virtual machine traffic is prioritized during these periods?
- A
Increase the shares assigned to the virtual machine traffic resource pool in NIOC.
- B
Enable Load-Based Teaming (LBT) on the distributed switch.
- C
Configure a dedicated VMkernel adapter for virtual machine traffic.
- D
Enable the Network Resource Reservation feature for critical virtual machine traffic in NIOC.
Show answer and explanation
Correct answer: A
Explanation
Network I/O Control (NIOC) is designed to manage and prioritize network traffic during periods of contention. By increasing the shares assigned to critical virtual machine traffic, you ensure that it receives a proportionally higher allocation of bandwidth compared to other traffic types. This is the recommended approach for dynamic prioritization in NIOC.
- A. Correct.
Increasing the shares assigned to the virtual machine traffic resource pool in NIOC ensures that critical traffic is prioritized during periods of contention by allocating it more bandwidth relative to other traffic types.
- B. Incorrect.
Enabling Load-Based Teaming (LBT) optimizes the usage of physical uplinks but does not directly prioritize specific traffic types like critical virtual machine traffic during contention.
- C. Incorrect.
Configuring a dedicated VMkernel adapter is used for management or storage traffic, but it does not prioritize traffic in the same way NIOC does.
- D. Incorrect.
The Network Resource Reservation feature is not used to dynamically allocate bandwidth during contention. It reserves fixed bandwidth, which may not be ideal for dynamic traffic prioritization.
