2V0-71.23 Question 264
Single answerYou are configuring vSphere with Tanzu in your environment and need to define a Virtual Machine (VM) Class for Developer Namespaces. The developers have requested a consistent resource allocation for their workloads, and you want to ensure that the VM Class is designed to provide guaranteed CPU and memory resources. Which type of VM Class configuration should you use?
- A
Guaranteed VM Class
- B
Best Effort VM Class
- C
Burstable VM Class
- D
Custom VM Class with Overcommit
Show answer and explanation
Correct answer: A
Explanation
VM Classes in vSphere with Tanzu provide predefined configurations for CPU and memory resources to ensure consistent and predictable performance for workloads. The Guaranteed VM Class is specifically designed to reserve resources fully, ensuring that workloads receive dedicated resources without contention, which is ideal for developers requiring consistent resource allocation. Other VM Class types like Best Effort or Burstable do not provide the level of resource guarantee needed in this scenario.
- A. Correct.
Guaranteed VM Class ensures that CPU and memory resources are fully reserved, providing a consistent and predictable performance level, which meets the developers' request for guaranteed resources.
- B. Incorrect.
Best Effort VM Class does not guarantee resource reservations and is suitable for workloads that can tolerate resource contention, making it unsuitable for this scenario.
- C. Incorrect.
Burstable VM Class allows for variable resource allocation based on demand but does not guarantee resources, which does not meet the developers' requirements for consistency.
- D. Incorrect.
Custom VM Class with Overcommit allows you to define custom configurations but may not guarantee resource reservation unless explicitly specified, which contradicts the developers' need for guaranteed resources.
