An architect had been given a constraint to use an existing storage array to support...

The constraint forces the use of the existing array. However, there’s a risk that performance/capacity may be insufficient. VMware’s best practice for risk mitigation in RACR is to plan for contingency.

A is correct because securing budget allocation for additional hardware addresses the risk if the array cannot meet requirements.

B (RAID mirroring) improves redundancy, not performance or capacity.

C contradicts the constraint (cannot ignore existing array).

D (extra Fibre Channel switches) doesn’t address storage array performance/capacity.

Thus, the best mitigation is budget planning for new hardware if the array fails to meet requirements.
