VCP-VMC 2024 Question 119
Select 3A company is planning to deploy a VMware Cloud on AWS Software-Defined Data Center (SDDC) and needs to ensure that the configuration aligns with their workload requirements. The company has determined that their workloads will require the following:
- High availability for critical applications
- Sufficient storage capacity for 100 TB of data with redundancy
- A minimum of 20 vCPUs and 64 GB of memory per workload
Which configuration sizing considerations should the company prioritize to ensure their VMware Cloud SDDC meets these requirements?
- A
Ensure the cluster includes at least three hosts to provide high availability and N+1 redundancy.
- B
Verify that each host in the cluster has sufficient local storage to meet the 100 TB storage requirement, considering overhead for redundancy.
- C
Configure the cluster with Elastic DRS enabled to automatically adjust resources based on load.
- D
Ensure that the host type selected provides sufficient vCPU and memory per workload to meet the application requirements.
- E
Include stretched clusters to enable cross-region high availability for critical applications.
Show answer and explanation
Correct answers: A, B, D
Explanation
To properly size a VMware Cloud SDDC, the configuration must address specific workload requirements, including high availability, sufficient storage capacity with redundancy, and appropriate resource allocation for vCPU and memory. A three-host cluster ensures high availability and redundancy. Storage sizing must accommodate the 100 TB requirement while factoring in overhead for redundancy. Host selection is crucial to provide the necessary compute resources per workload. While Elastic DRS and stretched clusters can enhance scalability and resilience, they are not mandatory for meeting the requirements outlined in the question.
- A. Correct.
Correct: A three-host cluster is the minimum requirement for high availability and N+1 redundancy in VMware Cloud on AWS. This ensures workloads can continue running even in the event of a host failure.
- B. Correct.
Correct: Sufficient local storage needs to be provisioned per host to meet the total 100 TB requirement, accounting for redundancy and disk overhead.
- C. Incorrect.
Incorrect: While Elastic DRS is useful for resource optimization, it is not a primary requirement for the stated workload needs. The question focuses on sizing considerations, not dynamic resource management.
- D. Correct.
Correct: Each host must provide enough vCPU and memory per workload to meet the application requirements. Proper host type selection is critical for ensuring performance.
- E. Incorrect.
Incorrect: Stretched clusters are not explicitly required for achieving high availability within a single deployment. The question specifies high availability but does not demand cross-region resilience.
