2. B. Production data access is from Unity but the clients still connect to the interface of the VNX.
3. C. Production data access is permanently set on Unity and the original data is deleted from VNX.

2. B. WAN compression is not required to Unity systems
3. C. CHAP security is not required between Unity systems
4. D. Internet connectivity is not required for every Unity system

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 Unity to a primary host.
Which solution will meet the requirement and provide space efficiency?

1. A. Create a snapshot of the LUNConfigure LUN access for the secondary hostAttach the snapshot to the secondary host
2. B. Create a snapshot of the LUNConfigure snapshot access to the LUN for the secondary hostAttach the snapshot to the secondary host
3. C. Create a Synchronous Replication session for the LUNConfigure access to the replica LUN for thesecondary hostAttach the secondary host
4. D. Create an Asynchronous Replication on session for the LUNConfigure access to the replica LUN for the secondary hostAttach the secondary host

Correct Answer: B
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.

A Windows test server ran a stress test program that generated a large amount of throughput. This resulted in performance slowdowns on production hosts sharing the same VMFS datastore.
What Dell EMC Unity XT feature can the storage administrator use to prevent a re-occurrence of this problem?

1. A. Data Reduction
2. B. FAST Cache
3. C. File System Quotas
4. D. Host I/O Limits

Correct Answer: C

An administrator’s Unity system is configured with both a Fibre Channel CNA and a Fibre Channel I/O module. Which Fibre Channel port on each SP must be used for native synchronous replication?

1. A. CNA FC port 5
2. B. I/O module FC port 2
3. C. CNA FC port 4
4. D. I/O module FC port 5

Correct Answer: C
Only one FC port can be configured and used for synchronous replication. Once an FC port is assigned, it will continue to act as the synchronous replication port and can never be changed. To determine the FC port used for synchronous replication, in the CLI console, run the command /remote/sys show -detail. Port information, similar to the following example, will appear in the output:
Synchronous FC ports = spb_fc4, spa_fc4 References:
