VCP-VMC 2024 Question 117
Single answerYou are designing a VMware Cloud on AWS Software-Defined Data Center (SDDC) for a customer workload with high CPU demand and moderate storage requirements. The customer expects the workload to grow significantly over time. Which configuration sizing consideration should you prioritize during the planning phase?
- A
Ensure that the cluster has sufficient vCPU resources to meet both current and future workload demands.
- B
Focus primarily on allocating storage capacity, as storage usage often grows faster than CPU usage.
- C
Configure the cluster to use Elastic DRS (Elastic Distributed Resource Scheduler) for automatic scaling, regardless of initial sizing.
- D
Prioritize memory (RAM) capacity over CPU and storage since memory bottlenecks are more common in VMware Cloud SDDC workloads.
Show answer and explanation
Correct answer: A
Explanation
When designing an SDDC for workloads with high CPU demand and expected growth, ensuring sufficient vCPU resources is critical during the planning phase. While VMware Cloud on AWS provides scalability features like Elastic DRS, initial sizing must prioritize the most critical resource to meet workload demands effectively. In this scenario, CPU is the key factor, with storage and memory being secondary considerations based on the described workload characteristics.
- A. Correct.
Correct. High CPU demand and anticipated growth indicate that vCPU resources should be the primary focus during the sizing phase. VMware Cloud on AWS allows for elasticity, but initial sizing must account for workload-specific requirements to prevent resource contention.
- B. Incorrect.
Incorrect. While storage is important, the scenario specifies moderate storage requirements, making it a secondary concern compared to CPU in this case.
- C. Incorrect.
Incorrect. Elastic DRS can help with scaling, but it is a reactive mechanism. Proper initial sizing is critical, especially in environments with high CPU demand and expected growth.
- D. Incorrect.
Incorrect. Memory is important, but the scenario emphasizes high CPU demand. Memory sizing should align with workload requirements but is not the primary concern here.
