2V0-21.23 Question 319
Select 2A VMware administrator is configuring Network I/O Control (NIOC) version 3 on a vSphere Distributed Switch (vDS) in a virtualized environment. The administrator needs to ensure that critical workloads like vMotion and Fault Tolerance (FT) traffic are prioritized over less-critical traffic such as vSAN and management traffic. Which steps should the administrator take to achieve this goal?
- A
Assign higher shares to vMotion and FT traffic in the NIOC resource allocation settings.
- B
Create a custom network resource pool and assign it to vMotion and FT traffic.
- C
Enable Network I/O Control on the vSphere Distributed Switch.
- D
Set up limits for vSAN and management traffic in the NIOC resource allocation settings.
- E
Configure physical NIC teaming policies to prioritize vMotion and FT traffic.
Show answer and explanation
Correct answers: A, C
Explanation
To prioritize critical workloads like vMotion and Fault Tolerance (FT) traffic using Network I/O Control (NIOC), the administrator must enable NIOC on the vSphere Distributed Switch and assign higher shares to these traffic types in the NIOC resource allocation settings. This ensures bandwidth allocation is adjusted during network contention. Custom resource pools, traffic limits, and NIC teaming policies are either unnecessary or unrelated to prioritizing traffic within NIOC.
- A. Correct.
Correct: Assigning higher shares to vMotion and FT traffic ensures these workloads are prioritized when there is network contention.
- B. Incorrect.
Incorrect: Creating a custom network resource pool is not required for prioritizing traffic in NIOC. Traffic types like vMotion and FT are already predefined within the NIOC settings.
- C. Correct.
Correct: Enabling Network I/O Control on the vSphere Distributed Switch is a prerequisite for configuring traffic prioritization and share settings.
- D. Incorrect.
Incorrect: Setting up limits restricts bandwidth but does not directly prioritize traffic. This step is not required in this specific scenario.
- E. Incorrect.
Incorrect: NIC teaming policies impact redundancy and load balancing, but they do not interact with NIOC prioritization settings directly.
