VCP-VMC 2024 Question 168
Single answerAn organization using VMware Cloud on AWS has recently experienced a surge in traffic to their workloads, resulting in performance degradation. To address this, the organization decides to leverage dynamic SDDC scale-out. What is a key requirement to enable dynamic scaling of the Software-Defined Data Center (SDDC) in VMware Cloud on AWS?
- A
Ensure that Elastic DRS (Elastic Distributed Resource Scheduler) is enabled and configured.
- B
Configure a dedicated Direct Connect connection between the on-premises data center and the VMware Cloud SDDC.
- C
Manually add additional hosts to the SDDC cluster using the VMware Cloud Console.
- D
Ensure that the AWS account linked to the VMware Cloud SDDC has sufficient capacity and permissions.
Show answer and explanation
Correct answer: A
Explanation
Dynamic SDDC scale-out allows VMware Cloud on AWS environments to automatically adjust the number of hosts in a cluster based on workload demands. This functionality is managed by Elastic DRS, which monitors resource usage and provisions or removes hosts as needed. Enabling Elastic DRS is a critical step in implementing dynamic scaling. Other options may be relevant to the operation or connectivity of the SDDC but are not directly tied to enabling dynamic scale-out.
- A. Correct.
Correct. Elastic DRS is a core component that automatically manages host scaling in VMware Cloud on AWS. It dynamically provisions or removes hosts based on workload demand.
- B. Incorrect.
Incorrect. While Direct Connect can improve connectivity and performance between on-premises and VMware Cloud, it is not a requirement for dynamic SDDC scale-out.
- C. Incorrect.
Incorrect. Dynamic scale-out via Elastic DRS does not require manual intervention to add hosts. It is an automated process.
- D. Incorrect.
Incorrect. Although sufficient AWS account capacity and permissions are important for the overall operation of the SDDC, they are not specifically a requirement for enabling dynamic SDDC scale-out.
