VCP-VMC 2024 Question 49
Single answerA company is running a critical workload in VMware Cloud on AWS. The workload has experienced sudden spikes in resource demand during peak business hours, causing performance degradation. The company wants to ensure sufficient resources are available to handle these spikes without overcommitting resources unnecessarily. Which scaling option should the company use to address this requirement?
- A
Elastic DRS (Distributed Resource Scheduler)
- B
Manual Host Addition
- C
Auto-Scaling for Workload VMs
- D
vSphere DRS in Balanced Mode
Show answer and explanation
Correct answer: A
Explanation
Elastic DRS is the most appropriate option for this scenario as it dynamically adds or removes hosts from the VMware Cloud on AWS cluster based on the workload's resource demands. This ensures resources are available during spikes without manual intervention, aligning with the company's requirement to avoid overcommitting resources unnecessarily.
- A. Correct.
Elastic DRS in VMware Cloud on AWS automatically scales the number of hosts in the cluster based on predefined policies, ensuring additional resources are added during sudden spikes in demand.
- B. Incorrect.
Manual Host Addition can address increasing resource needs, but it is not an automated solution, making it less suitable for handling unpredictable spikes in resource demand.
- C. Incorrect.
Auto-Scaling for Workload VMs is not a native feature of VMware Cloud on AWS. Elastic DRS handles host-level scaling, while applications would require different mechanisms for VM-level scaling.
- D. Incorrect.
vSphere DRS in Balanced Mode ensures balanced resource distribution across hosts within a cluster but does not add or remove hosts dynamically to handle spikes in demand.
