2V0-71.23 Question 261
Select 3You are tasked with deploying a Kubernetes cluster using vSphere with Tanzu. During the deployment, you need to select an appropriate Virtual Machine (VM) Class for your workloads. Which of the following statements accurately describe the purpose and configuration of VM Classes in vSphere with Tanzu?
- A
VM Classes define resource guarantees and limits for virtual machines running in a Tanzu Kubernetes cluster.
- B
VM Classes are specific to each workload and cannot be shared across namespaces.
- C
VM Classes can be customized to create specific CPU and memory configurations not available in the default classes.
- D
VM Classes are automatically assigned by vSphere with Tanzu and cannot be modified by administrators.
- E
VM Classes provide a standardized way to manage resource allocation for virtual machines in a Kubernetes environment.
Show answer and explanation
Correct answers: A, C, E
Explanation
VM Classes in vSphere with Tanzu are a critical feature for managing resource allocation in Kubernetes environments. They define CPU and memory resource guarantees and limits, ensuring workloads perform reliably. Administrators can use default VM Classes or create custom ones to align with specific workload needs. This standardized approach simplifies resource management and promotes consistency across clusters and namespaces.
- A. Correct.
Correct: VM Classes define resource guarantees (e.g., CPU and memory) and limits for virtual machines, ensuring predictable performance for workloads.
- B. Incorrect.
Incorrect: VM Classes are not specific to individual workloads; they can be used across namespaces for consistent resource management.
- C. Correct.
Correct: Administrators can create custom VM Classes to meet specific workload requirements that default classes may not address.
- D. Incorrect.
Incorrect: VM Classes are not automatically assigned and can be modified or created by administrators to suit workload needs.
- E. Correct.
Correct: VM Classes provide a standardized approach to managing resource allocation, making resource planning and performance optimization more predictable.
