VCP-VMC 2024 Question 50
Select 2A company is running its workloads on VMware Cloud on AWS and is experiencing periodic spikes in demand during end-of-quarter reporting. They want to ensure that their environment can handle these spikes without overprovisioning resources during normal operations. Which scaling option(s) in VMware Cloud on AWS would best address this requirement?
- A
Enable Elastic DRS (Distributed Resource Scheduler) with the Optimize for Best Performance policy
- B
Manually add hosts to the VMware Cloud SDDC to handle the increased demand
- C
Enable Elastic DRS with the Optimize for Lowest Cost policy
- D
Switch the workloads to a reserved host model to ensure consistent performance
- E
Use VMware vSphere Auto Deploy to dynamically allocate resources during peak times
Show answer and explanation
Correct answers: A, C
Explanation
Elastic DRS is a key feature in VMware Cloud on AWS that enables automatic scaling of resources based on demand. By selecting either the 'Optimize for Best Performance' policy or the 'Optimize for Lowest Cost' policy, the company can handle periodic spikes effectively. The former ensures that performance requirements are met during critical periods, while the latter balances cost and performance, making both options suitable depending on the organization's priorities.
- A. Correct.
Elastic DRS with the Optimize for Best Performance policy automatically scales out resources to handle demand spikes, ensuring the environment can meet performance needs during critical periods.
- B. Incorrect.
Manually adding hosts can meet the demand but is not an efficient solution for periodic spikes, as it requires manual intervention and may lead to overprovisioning during normal operations.
- C. Correct.
Elastic DRS with the Optimize for Lowest Cost policy scales resources more conservatively, which can help address spikes while minimizing costs, though it may not provide the same level of performance as the 'Best Performance' policy.
- D. Incorrect.
Switching to a reserved host model does not dynamically scale the environment and can lead to inefficiency during periods of low demand, making it unsuitable for periodic spikes.
- E. Incorrect.
VMware vSphere Auto Deploy is used for provisioning ESXi hosts and does not dynamically allocate resources in VMware Cloud on AWS. It is not applicable to this scenario.
