VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 82
An architect is tasked with designing a new VMware software-defined data center (SDDC) solution for an online retail customer who has a primary and secondary data center as well as 10 distribution hubs.
The customer has provided the following business requirements to help inform the design:
✑ The solution must support the running of up to 1,000 concurrent virtual machines across the primary and secondary data center.
✑ The solution must support the running of up to 20 concurrent virtual machines in each distribution hub.
✑ The solution must support the separation of management and lines-of-business application virtual machines.
✑ All management components (including directory services, backup, automation, operations and logging) must be deployed to the primary data center.
✑ All virtual infrastructure components must have redundancy of N+1.
✑ All sites are connected to each other using a wide area network that has multiple diversely routed links.
✑ The solution should support a monthly uptime target of 99.9%.
✑ The recovery time objective (RTO) for the solution must be four hours.
✑ The recovery point objective (RPO) for the solution must be 24 hours.
Given the information from the customer, which assumption should the architect include in the design?
Answer options
- A. All business application virtual machines can be deployed into a single cluster within the primary data center.
- B. Each distribution hub should be configured with a backup device.
- C. The wide area network has sufficient bandwidth to support centralized management.
- D. Each cluster will have a minimum of four hosts.
Correct answer: B
Explanation
The correct assumption is that each distribution hub should be configured with a backup device, ensuring that data is protected and can be recovered in case of failure. The other options do not align with the customer's requirements; for instance, deploying all business applications in one cluster could impact performance and management, while the bandwidth of the WAN was not specified, and the minimum host requirement was not provided.
