Best answers are B & C as there is no E, it's simply called 'Rapid Scaling'

Elastic Distributed Resource Scheduler (DRS) in VMware Cloud on AWS allows clusters to automatically scale based on resource demands. Among the options provided, the following are the Elastic DRS policies designed to handle automatic scale-out and scale-in scenarios: B. Optimize for Best Performance policy: This policy is designed to maintain higher spare capacity and is quicker to add hosts when demand increases, ensuring optimal performance. C. Optimize for Lowest Cost policy: This policy is more conservative in adding new hosts and will attempt to run the cluster closer to its limits before scaling out, thus reducing costs. The other options provided aren't standard Elastic DRS policies for VMware Cloud on AWS as of my last update in 2022. So, the correct answers are: B. Optimize for Best Performance policy C. Optimize for Lowest Cost policy

Could be B, C and E. All support scale out and scale in.

B&C are correct
