VCP-VMC 2024 Question 167
Select 3A company is running VMware Cloud on AWS and experiences periodic spikes in workload demand. They want to ensure their Software-Defined Data Center (SDDC) can dynamically scale out to handle these spikes without manual intervention. What is necessary to enable dynamic SDDC scale-out in this environment?
- A
Enable Elastic DRS with a policy that supports automatic scale-out.
- B
Manually provision additional hosts during demand spikes.
- C
Configure a minimum and maximum host count in the SDDC cluster settings.
- D
Ensure sufficient AWS capacity is available for scaling out.
- E
Install and configure VMware vSphere Replication for the SDDC.
Show answer and explanation
Correct answers: A, C, D
Explanation
Dynamic SDDC scale-out in VMware Cloud on AWS relies on Elastic DRS to automatically add hosts during workload spikes, provided that a policy is configured and AWS capacity is available. Additionally, SDDC cluster settings must define allowable scaling limits (minimum and maximum host count) for Elastic DRS to operate effectively. Manual provisioning and unrelated features like vSphere Replication do not support the dynamic scale-out process.
- A. Correct.
Elastic DRS (Elastic Distributed Resource Scheduler) must be enabled with a policy that allows automatic scale-out to dynamically add hosts during demand spikes.
- B. Incorrect.
Manually provisioning additional hosts is not part of dynamic scale-out, as this involves manual intervention, which contradicts the concept of dynamic scaling.
- C. Correct.
Defining a minimum and maximum host count in the SDDC cluster settings is necessary to allow Elastic DRS to scale out within the specified limits.
- D. Correct.
Dynamic scale-out depends on available AWS capacity to add hosts to the SDDC. Without sufficient AWS resources, scale-out operations cannot occur.
- E. Incorrect.
VMware vSphere Replication is unrelated to dynamic SDDC scale-out. It focuses on data replication rather than scaling compute resources.
