Question 1
An architect had been given a constraint to use an existing storage array to support the virtual infrastructure design project.
The architect documents the following:
Assumption 01: The existing storage array has sufficient capacity and performance to support the intended workloads.
Risk 01: There is a risk that the performance and capacity of the existing storage array may not be sufficient for the solution.
How would the architect mitigate the risk?
- AOption A:
Ensure that the customer allocates budget for new hardware in case the risk is realized.
- BOption B:
Setup a RAID mirror configuration on the existing storage array for redundancy.
- COption C:
Ignore the constraint and design the solution using VMware vSAN Express Storage Architecture (ESA).
- DOption D:
Request for additional budget to purchase more Fibre Channel switches.
Show answer and explanation
Correct answer: A
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.
