Q36. An administrator initially created a Thin Provisioned file system on Dell EMC Unity. They now want to change that file system (FS) to Thick Provisioned.
What is a consideration?

Unmap/unmount the FS and use the Initial Configuration Wizard

The FS cannot be changed from Thin to Thick

Unmap/Unmount the FS and change FS properties

Convert the FS from Thin to Thick through Unisphere

Q37. A storage administrator is planning to move a NAS Server to the peer SP on a Dell EMC Unity system. The NAS Server and two of its associated file systems have active asynchronous replication sessions to a remote Dell EMC Unity system.
How should the storage administrator proceed?

Manually pause the replication sessions for the NAS Server and file systems.

Set the RPO value to 1440 for the NAS Server and file system replication sessions

Set the RPO value to 0 for the NAS Server and file system replication sessions

Failover the replication sessions for the NAS Server and file systems

Q42. Match each integrated ESRS characteristic with its attribute.

Q43. A storage administrator is tasked with creating a DR solution for block and file storage resources. The company has multiple regional and international sites containing a mix of Dell EMC Unity XT and Dell EMC UnityVSA systems.
What are considerations for the storage administrator in creating the DR solution?

Synchronous remote replication should be restricted to within 100 miles between sites to keep latency below 10 ms Block storage resources can be replicated synchronously and asynchronously

Asynchronous replication ensures zero data loss the remote replica in disaster conditions Block storage resources can be replicated synchronously and asynchronously

Asynchronous replication over long-distance does not impact latency
