VCP-VCF Administrator 2024 Question 188
Select 3You are tasked with configuring Network I/O Control (NIOC) on a VMware Cloud Foundation environment to prioritize network traffic for vSAN, vMotion, and management workloads. Which of the following steps are required to configure NIOC policies effectively?
- A
Enable Network I/O Control on the Distributed Switch.
- B
Define traffic classes for each workload type and assign bandwidth shares.
- C
Set the MTU size to 9000 for all traffic types to optimize performance.
- D
Assign physical NICs to specific traffic classes to segregate workloads.
- E
Verify that the physical network infrastructure supports the configured bandwidth allocation.
Show answer and explanation
Correct answers: A, B, E
Explanation
Configuring Network I/O Control (NIOC) requires enabling the feature on the Distributed Switch, defining traffic classes with appropriate bandwidth shares, and verifying that the physical network can support the configurations. These steps ensure that network resources are allocated efficiently across workloads such as vSAN, vMotion, and management, avoiding contention and maximizing performance.
- A. Correct.
Enabling Network I/O Control (NIOC) on the Distributed Switch is a prerequisite for applying traffic management policies.
- B. Correct.
To prioritize traffic, traffic classes must be defined, and bandwidth shares assigned to ensure proper resource allocation.
- C. Incorrect.
While setting MTU to 9000 may improve performance for some workloads, it is not directly related to configuring NIOC policies.
- D. Incorrect.
Assigning physical NICs to specific traffic classes is not required. Instead, NIOC works by managing traffic at the virtual switch level.
- E. Correct.
Ensuring the physical network infrastructure supports the configured bandwidth allocation is critical to avoid bottlenecks and ensure the policies are effective.
