VCP-VCF Administrator 2024 Question 187
Single answerAn administrator is tasked with configuring Network IO Control (NIOC) on a vSphere Distributed Switch (vDS) to ensure that critical workloads such as vSAN traffic and vMotion traffic are prioritized during network congestion. What is the first step the administrator should take to enable NIOC functionality?
- A
Enable Network IO Control on the vSphere Distributed Switch.
- B
Create a new traffic shaping policy for each traffic type.
- C
Assign a high priority to vSAN and vMotion traffic in the physical network.
- D
Configure bandwidth reservations for each network resource pool.
Show answer and explanation
Correct answer: A
Explanation
Network IO Control (NIOC) is a feature of the vSphere Distributed Switch that allows administrators to allocate and prioritize bandwidth for different types of traffic, such as vSAN, vMotion, and management traffic. The first step to leveraging NIOC is enabling it on the vSphere Distributed Switch. Once enabled, administrators can define resource pools and configure bandwidth reservations or limits for each traffic type.
- A. Correct.
Correct. Network IO Control must first be enabled on the vSphere Distributed Switch before any further configuration, such as bandwidth reservations or policies, can take place.
- B. Incorrect.
Incorrect. Traffic shaping policies are not directly related to enabling NIOC. They are used for controlling outbound traffic but are not required to activate NIOC.
- C. Incorrect.
Incorrect. NIOC is configured within the vSphere environment itself, not at the physical network level.
- D. Incorrect.
Incorrect. Bandwidth reservations for resource pools cannot be configured until Network IO Control is enabled on the vSphere Distributed Switch.
