2V0-21.23 Question 318
Select 3An administrator is tasked with configuring Network I/O Control (NIOC) on a vSphere Distributed Switch (vDS) to prioritize storage traffic in a virtualized environment. The environment has the following requirements:
- Storage traffic must have guaranteed bandwidth.
- Management traffic should not exceed 10% of the total bandwidth.
- vMotion traffic should not exceed 20% of the total bandwidth.
What steps should the administrator take to meet these requirements?
- A
Set up NIOC and define a custom network resource pool for storage traffic with a reservation policy.
- B
Enable NIOC on the vSphere Distributed Switch and configure bandwidth limits for Management and vMotion traffic.
- C
Configure a network adapter teaming policy to ensure storage traffic is mapped to a dedicated uplink.
- D
Use NIOC to assign shares to each traffic type and configure limits for Management and vMotion traffic.
- E
Disable NIOC and manually configure traffic shaping policies on each uplink port.
Show answer and explanation
Correct answers: A, B, D
Explanation
Network I/O Control (NIOC) allows administrators to prioritize and control bandwidth allocation for various traffic types on a vSphere Distributed Switch. To meet the requirements, the administrator should enable NIOC, configure custom resource pools for storage traffic with guaranteed bandwidth, and set appropriate shares and limits for Management and vMotion traffic. Disabling NIOC or relying solely on adapter teaming is not sufficient to meet these requirements.
- A. Correct.
Correct: Setting up NIOC and creating a custom network resource pool for storage traffic with a reservation policy ensures guaranteed bandwidth is provided as required.
- B. Correct.
Correct: Enabling NIOC and configuring bandwidth limits for Management and vMotion traffic ensures they do not exceed 10% and 20% of total bandwidth, respectively.
- C. Incorrect.
Incorrect: Configuring adapter teaming policies focuses on physical uplink redundancy or load balancing but does not address bandwidth prioritization through NIOC.
- D. Correct.
Correct: Using NIOC to assign shares to each traffic type and configuring limits for Management and vMotion traffic ensures proper prioritization and bandwidth control.
- E. Incorrect.
Incorrect: Disabling NIOC and manually configuring traffic shaping policies does not meet the requirements for dynamic and efficient resource allocation.
