VCP-VMC 2024 Question 166
Select 2A cloud administrator is managing a VMware Cloud on AWS deployment and notices that the workload demands are increasing beyond the current capacity of the Software-Defined Data Center (SDDC). The administrator needs to ensure dynamic scalability of the SDDC to meet the growing demands while maintaining cost-efficiency. Which steps should the administrator take to enable dynamic SDDC scale-out?
- A
Enable Elastic DRS (Distributed Resource Scheduler) in the VMware Cloud on AWS console.
- B
Manually add additional hosts to the cluster to scale out the SDDC.
- C
Configure Elastic DRS policies for cost, performance, or a balanced approach.
- D
Set up an external load balancer to distribute workloads across multiple SDDCs.
- E
Monitor resource utilization using VMware vRealize Operations and adjust capacity manually.
Show answer and explanation
Correct answers: A, C
Explanation
Dynamic SDDC scale-out in VMware Cloud on AWS is achieved by enabling Elastic DRS, which automates the process of scaling the SDDC based on resource demands. Configuring Elastic DRS policies ensures proper alignment with business priorities such as cost-efficiency, performance, or balance. This eliminates the need for manual intervention and optimizes resource utilization.
- A. Correct.
Enabling Elastic DRS allows the SDDC to dynamically scale out by automatically adding or removing hosts based on workload demands, ensuring efficient resource utilization.
- B. Incorrect.
Manually adding hosts to the cluster does not utilize the dynamic capabilities of Elastic DRS and may lead to inefficiencies in scaling operations. This is not a step specific to dynamic scale-out.
- C. Correct.
Elastic DRS policies allow administrators to define whether the scaling actions prioritize cost, performance, or a balance, which is critical for enabling dynamic SDDC scale-out.
- D. Incorrect.
Setting up an external load balancer is unrelated to dynamic SDDC scale-out. Load balancers are used for balancing traffic and do not directly influence the scaling of SDDC resources.
- E. Incorrect.
Monitoring resource utilization manually and adjusting capacity does not leverage dynamic scale-out capabilities and is a reactive rather than proactive measure.
