A customer currently owns a FlashArray//XL running a file-based workload. Due to new regulations, the customer is looking to improve the application RTO/RPO by replicating to a second data center that is 10 km away and has a latency of 5 ms RTT. The priority for the customer is to design a solution with the best possible RTO/RPO while minimizing cost.  Which solution should the SE propose to meet the requirements?

A customer with a single FlashArray needs to enhance their data protection strategy following ransomware attacks against similar companies in the area. The customer has the following requirements:Protect data against ransomware attackProtect data against malicious employeesBe able to recover up to seven days after an incidentMinimal additional cost What solution should the systems engineer suggest?

A customer requires the lowest latency possible for their block storage. They currently have servers that utilize 25G NICs and do NOT wish to add additional physical hardware to their servers. Which option should the systems engineer recommend?

White Finger Syndrome is a circulatory problem caused by vibration exposure.

Refer to the exhibit. Scroll to the right to see the full image.     A systems engineer is reviewing a customer’s FlashArray.   Based on the information in the exhibit, what should the systems engineer do next?

Decompression sickness results from:

A storage administrator plans to replicate 100TB of already encrypted data to a target FlashArray. The customer has the following parameters:The schedule is set to replicate daily. The retention period for data at the target is set to seven days.The data change rate is 5% per day.Due to site constraints, the customer needs to use Asynchronous Replication. How much usable capacity will the snapshots consume on the target array?

A customer uses asynchronous snapshot replication as part of its DR strategy. The Protection Group policy is set to replicate at 8:00am and is destroying and eradicating the snapshot data from the day before, copying the new snapshot data on the remote array. The company CEO is concerned about the increase of cyber attacks and wants to employ a data protection strategy on the arrays without affecting DR capability.  What should the systems engineer recommend?

A client is looking to replace their end of life hybrid array. The IT director wants a solution that will deliver the same level of performance. The SE performs an assessment and discovers the following: 258 TB of VMware VM’s7-10 ms of read latency2-6 ms of write latency18,567 IOPS243 MiB/s Bandwidth Which FlashArray model meets the performance needs of the workload without overdesigning the solution?

A customer with a hybrid array is considering upgrading to a Pure Storage FlashArray. The systems engineer recommends adopting a single data pack of denser DFMs. However, a competitor argues this approach will hurt performance and suggests using many small SSDs for superior results. How should the systems engineer respond?
