A customer wants to protect all data stored on the FlashArray from a ransomware attack with a once-daily snapshot and SafeMode enabled with a three-day eradication timer. Currently, the customer leverages snapshots on five-minute intervals to protect a mission-critical database with a high change rate, which is only a portion of the total data stored. The snapshots are created by the Database Administrator (DBA) using Python scripts. The DBA script calls for eradication of the snapshots after 24 hours because the high change rate causes excessive snapshot storage consumption. With SafeMode enabled, the DBA script will fail to eradicate the snapshots. There is not enough storage capacity on the FlashArray to hold the DBA snapshots created every five minutes for the duration of the three-day eradication timer, and the customer did not budget for a storage expansion this year. Which recommendation should the SE make to protect all data with SafeMode without filling up the FlashArray?

In preparing to set up home directories on FlashArray File Services for a new corporate office, what steps should be followed to ensure the home directories are efficiently created and accessible via both NFS and SMB protocols?

A prospective customer provides the following application requirements during a discovery workshop:Mission-critical applications that require: zero RTO, zero RPO between metro sites, with an out of region 3rd copyBusiness-critical applications that require up to 5 min RPO and near-zero RTO between different sitesTest and Dev applications that require a single application instance with hybrid DR capability Which three FlashArray features should the systems engineer recommend to fulfill these specific customer requirements? (Choose three.)

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?
