   A consultant is sizing a midrange storage solution for a customer that has a critical application with a peak IOPS requirement of 100,000 and a capacity requirement of 50 TB. The customer wants to use RAID 5 to maximize usable capacity. The consultant calculates that with RAID 5, the solution would need 60 drives to meet the IOPS requirement, but this would provide 120 TB of usable capacity, which is far more than needed. What should the consultant recommend?

   • AUse RAID 10 instead, which would require fewer drives to meet the IOPS requirement and provide closer to the needed capacity.
   • BUse a smaller number of high-performance SSDs to meet the IOPS requirement, and use the remaining capacity for other workloads or leave it unallocated.
   • CReduce the IOPS requirement by negotiating with the customer to lower the performance target.
   • DUse RAID 5 as planned, since it meets both requirements, even though it over-provisions capacity.

   A storage consultant is working with a customer who wants to deploy a new midrange storage system. The customer has provided detailed performance and capacity requirements, but has not yet defined the business objectives or constraints. What is the most appropriate next step in the sales engagement?

   • AJump to the design phase and create a solution architecture based on the provided requirements.
   • BConduct a planning phase to clarify business objectives and constraints before proceeding to sizing.
   • CAsk the customer to sign a contract before proceeding with any technical work.
   • DProceed directly to the sizing phase, since the technical requirements are already known.

   A sales engineer is leading a midrange storage engagement for a customer that has a strict deadline to implement a new solution before the end of the quarter. The customer has provided a detailed set of technical requirements, but the sales engineer has not yet conducted a planning phase. The customer is pressuring the sales engineer to skip the planning phase and move directly to sizing to save time. What should the sales engineer do?

   • AConduct a shortened planning phase, focusing only on the most critical business objectives and constraints.
   • BRefuse to proceed until the customer completes a full planning phase.
   • CSkip the planning phase and proceed to sizing to meet the deadline.
   • DProceed directly to design, using the technical requirements to create a solution architecture.

   A consultant has designed a midrange storage solution for a customer's Oracle database. The design includes a RAID 10 configuration with 15K SAS drives. During the design validation step, the consultant simulates a drive failure and finds that the rebuild time is longer than the customer's recovery time objective (RTO). What should the consultant do?

   • AModify the design to use a different RAID level, such as RAID 6, to reduce rebuild time.
   • BAccept the design because RAID 10 is the most resilient option.
   • CAdjust the design to include a hot spare and use smaller capacity drives to reduce rebuild time.
   • DIncrease the number of drives in the RAID group to reduce rebuild time.

   A storage consultant is managing a midrange storage engagement for a customer that has a complex environment with multiple applications, each with different performance and capacity requirements. The customer has a limited budget and a tight timeline. The consultant has completed the planning phase and is about to start the sizing phase. Which approach best ensures the sizing phase is effective and efficient?

   • ASkip the sizing phase and use the planning phase data to create a design directly.
   • BFocus only on the most critical applications and assume the others have similar requirements.
   • CGather detailed requirements for every application, including performance, capacity, and growth, and then calculate the total requirements.
   • DUse a standard sizing template based on the number of applications, without gathering specific data.
