VMware vSphere 8.x Advanced Design (VCAP-DCV Design) — Question 41

An architect is designing a new vSphere-based solution for a customer.
During a requirement gathering workshop, the following information is provided:
The solution must have a primary and secondary site.
The solution must support a maximum of 1,000 concurrent workloads.
The profile of the workloads are as follows:

Production Workloads -
300 x Small: 1 vCPU, 2 GB RAM
400 x Medium: 2 vCPU, 6 GB RAM
100 x Large: 4 vCPU, 8 GB RAM

Development Workloads -
200 x Small: 1 vCPU, 2 GB RAM
The corporate security policy states that, during normal operations, production workloads must be physically segregated from development workloads.
All production workloads are split evenly across the primary and secondary site.
All development workloads run only within the secondary site.
In the event of a disaster affecting workloads in the primary site, the secondary site must be capable of running all production and development workloads.
The vCPU to physical core ratio should be a maximum of 10:1 for production workloads and 20:1 for development workloads.
The solution should provide a minimum of N + 1 resiliency at each component level.
The target physical host hardware platform has already been defined by the company's hardware standards and therefore each host has the following configuration:
2 x 24 physical cores
768 GB RAM
2 x 100 GB SSD drives
6 x 10 GbE network cards
What is the minimum number of hosts required to meet the requirements?

Answer options

Correct answer: A

Explanation

The correct answer is A, as the total vCPU requirements for production and development workloads, along with the N + 1 resiliency, determine that at least 12 hosts are necessary to meet both workload and physical core ratios. The other options (B, C, D) do not provide sufficient capacity or fail to meet the required ratios and resiliency, resulting in inability to support the defined workloads.
