VMware vSphere 8.x Advanced Design (VCAP-DCV Design) — Question 57

An architect is documenting the logical design for a new vSphere solution. The following requirements have been provided to the architect by the customer for the design:
The solution must be deployed in two locations: DC1 and DC2
The solution must limit the impact radius of accidental changes by administrators
The solution must meet a recovery time objective (RTO) of four (4) hours and recovery point objective (RPO) of 24 hours
The solution must allow workloads to run in both DC1 and DC2 during normal operations
The solution must allow workloads to be moved bi-directionally between DC1 and DC2
The solution must use hyper-converged infrastructure for the virtual machine storage
The customer has also confirmed that the network connection between DC1 and DC2 has a 10 Gbps bandwidth with a maximum round trip latency of 4 ms.
The architect recommends the following design decision:
Use separate clusters in DC1 and DC2 to form a multi-region design
What should the architect include as justification for this design decision?

Answer options

• A. Sufficient capacity must be deployed in both DC1 and DC2 to support all running virtual machines.
• B. Using separate clusters mitigates the risk of an accidental change at the cluster level in DC1 from impacting DC2.
• C. Using separate clusters is the only configuration available that supports the RTO of four (4) hours.
• D. The network connection between DC1 and DC2 does not support the use of stretched clusters.

Correct answer: B

Explanation

The correct answer, B, indicates that using separate clusters helps prevent accidental changes in one cluster from affecting another, thus enhancing operational safety. Option A is incorrect as it does not directly justify the design choice. Option C is false because other configurations could also meet the RTO. Option D is inaccurate since the network connection supports stretched clusters; thus, it's not relevant to the justification.
