   What is the purpose of replication on Dell midrange storage arrays?

   • ATo create point-in-time copies for test and development
   • BTo provide a writable copy of a volume for application testing
   • CTo maintain a copy of data at a remote site for disaster recovery and business continuity
   • DTo reduce storage capacity by eliminating duplicate data blocks

   A financial services firm runs a critical SQL Server database on a Dell PowerStore array. They need to protect against logical corruption and accidental data deletion with a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 2 hours. The database is 5 TB and changes at a rate of 2% per hour. Which data protection strategy best meets the RPO/RTO while following Dell best practices?

   • AConfigure synchronous replication to a second PowerStore array and fail over to the replica on corruption.
   • BSchedule a snapshot every 15 minutes and replicate the snapshots to a remote PowerStore array for disaster recovery.
   • CTake a full snapshot of the database volume every 15 minutes using the array's snapshot scheduler.
   • DUse thin clones of the database volume taken every hour and keep them for 24 hours.

   A developer needs multiple writable copies of a production database for testing. According to Dell best practices, what is the recommended approach to create these copies efficiently?

   • ACopy the production volume to a new thick volume for each test instance
   • BCreate thin clones of the production volume for each test instance
   • CUse replication to create a remote copy and then make it writable
   • DTake a snapshot of the production volume and mount it as a writable volume

   What is a Dell best practice for managing data-at-rest encryption on midrange arrays?

   • AEnable encryption only on volumes that contain sensitive data
   • BUse the same encryption key for all arrays in the environment to simplify key management
   • CEnsure encryption keys are backed up and managed securely to prevent data loss
   • DDisable encryption during performance-intensive periods to avoid impact

   When configuring QoS policies on a Dell midrange array, what is a best practice to follow?

   • ASet QoS policies based on the performance requirements of each workload, prioritizing critical applications
   • BDisable QoS on all volumes to avoid any performance overhead
   • CUse the same QoS policy for all volumes to simplify management
   • DApply QoS policies only to volumes that are experiencing performance issues
