When configuring asynchronous remote replication, how many internal Unity Snapshots are configured and utilized on the source system by a single replication session?
Answer(s): B
Internal Snapshot (Replication Snapshot) are Unity Snapshots created by the system which are part of an asynchronous replication session. These Snapshots can be viewed in Unisphere, but user operations are not permitted. Each asynchronous replication session uses two internal snapshots taken on the source and destination storage resources.

A storage administrator is required to test a new version of an application loaded on a secondary host. The administrator must use existing data contained on a LUN provisioned from Dell EMC Unity XT to a primary host.Which solution will meet the requirement and provide space efficiency?
Attaching a snapshot is only applicable for block snapshots, and makes the snapshot available for host IO. A host must have Snapshot access or LUN and Snapshot access configured in order to access the snapshot. When a snapshot is attached, Unisphere provides the option to create a copy of the snapshot in case the administrator wants to preserve the current snapshot view for future use.
On which systems is Quality of Service available?
Answer(s): C
UnitVSA features Host I/O limits, also known as Quality of service.The EMC [Physical] Unity array comes with a pack of new hardware and software features focusing on the true unification:-Support for setting up Host I/O limits, also known as QOS, providing a more predictable performance for the workloads by putting limits on I/O throughputs and bandwidth-DPE reduced from a 7U footprint to an innovative 2U footprint-12 GB SAS back-end for the Unity DAEs; EMC VNX/VNXe supported only 6 GB SAS backend-Completely redesigned user interface based on HTML5
