VCP-VMC 2024 Question 165
Select 2A company utilizing VMware Cloud on AWS has recently experienced a surge in demand for its application workloads. They have noticed that their current Software-Defined Data Center (SDDC) cluster is nearing capacity. To address the issue, the company wants to scale out their SDDC dynamically without disrupting their workloads. Which of the following actions aligns with the concept of dynamic SDDC scale-out?
- A
Add additional hosts to the SDDC cluster manually through the VMware Cloud on AWS console.
- B
Enable Elastic DRS (Distributed Resource Scheduler) to automatically add hosts when resource thresholds are reached.
- C
Migrate workloads to another SDDC cluster in a different region to distribute the load.
- D
Configure auto-scaling policies for the SDDC to dynamically add and remove hosts as required.
- E
Manually power off non-essential VMs to free up resources within the current SDDC cluster.
Show answer and explanation
Correct answers: B, D
Explanation
Dynamic SDDC scale-out refers to the ability to adjust the capacity of an SDDC automatically based on workload demands. Elastic DRS and auto-scaling policies are key features that enable this functionality by dynamically adding or removing hosts without manual intervention. These solutions ensure that workloads are not disrupted during scaling operations, maintaining operational efficiency and performance.
- A. Incorrect.
While this action increases the capacity of the SDDC, it is a manual approach and does not align with the dynamic nature of SDDC scale-out.
- B. Correct.
Elastic DRS can automatically detect resource constraints and add hosts dynamically, making it a key feature for dynamic SDDC scale-out.
- C. Incorrect.
Migrating workloads to another SDDC cluster is a viable option for load distribution, but it is not part of the dynamic scale-out concept within a single SDDC.
- D. Correct.
Configuring auto-scaling policies ensures that the SDDC can dynamically scale out and in based on workload demands, which aligns with the concept of dynamic SDDC scale-out.
- E. Incorrect.
Manually powering off VMs to free up resources is a reactive, manual action and does not align with the proactive, automated nature of dynamic SDDC scale-out.
