2V0-71.23 Question 262
Single answerYou are managing a vSphere with Tanzu environment and need to deploy a Kubernetes workload on a specific virtual machine class. The workload requires high CPU and memory resources, and you want to ensure consistent performance by using a predefined VM class that aligns with these requirements. Which VM class should you choose?
- A
BestEffortSmall
- B
GuaranteedMedium
- C
BestEffortExtraLarge
- D
GuaranteedLarge
Show answer and explanation
Correct answer: D
Explanation
VM classes in vSphere with Tanzu define the CPU, memory, and reservation policies for virtual machines. 'Guaranteed' VM classes ensure dedicated and consistent resource allocation, making them suitable for performance-critical workloads. Since the workload requires high CPU and memory along with consistent performance, GuaranteedLarge is the most appropriate choice in this scenario.
- A. Incorrect.
BestEffortSmall is a VM class designed for workloads with minimal resource requirements and does not guarantee resource allocation, making it unsuitable for high-performance needs.
- B. Incorrect.
GuaranteedMedium provides guaranteed resource allocation but may still fall short for workloads with higher CPU and memory requirements.
- C. Incorrect.
BestEffortExtraLarge offers more resources than BestEffortSmall but still does not guarantee consistent resource allocation, which is critical for high-performance workloads.
- D. Correct.
GuaranteedLarge is a VM class that provides high CPU and memory resources with guaranteed allocation, ensuring consistent performance for demanding workloads.
