AReplication of compresses data is controlled by the bandwidth throttle setting.

BBy default, replication compresses data sent to the destination.

CThe source data is uncompressed, then replicated to the destination.

DThe source data is replicated to the destination, then uncompressed.

Answer : D

Question 2

A storage administrator is replicating a NAS Server from one Dell EMC Unity to another. The destination system has a different network scheme than their source system.

What operation must be done on the destination system NAS Server to ensure data is accessible after failover?

ANo changes required

BChange the Override properties

CCreate a new interface

DModify DNS Cache

Answer : B

Question 3

What describes the LUN Snapshot Copy operation?

AParent cannot be a snapshot copyCan only copy a detached snapshotHas an independent Retention Policy from the parent

BParent can be a snapshot copyCan only copy a detached snapshotHas an independent Retention Policy from the parent

CParent can be a snapshot copyCan copy an attached or detached snapshotInherits the parent Snapshot Retention Policy

DParent cannot be a snapshot copyCan copy an attached or detached snapshotInherits the parent Snapshot Retention Policy

Answer : B

Note: You can create copies of LUNs by cloning LUNs from the Snapshot copies in a volume. These FlexClone LUNs are readable and writable copies of the LUNs as the LUN existed when the Snapshot copy was created. Before you can clone a LUN, you must create a Snapshot copy (the backing Snapshot copy) of the LUN you want to clone.

Question 4

Which task must be performed on the storage system in order to access a file system read/write snapshot?

AConfigure Host Access to the LUN snapshots

BConfigure the NFS/SMB share to the file system snapshot

CConnect to the NFS/SMB share of the snapshot

DPerform the snapshot ''Attach to Host'' operation

Answer : B

Read-write snapshots can be made available to hosts as separate shares.

The Shared property is applicable to file snapshots only, and indicates whether the snapshot is currently available to clients as a

share. The default value is No, and changes to Yes when the read-write file system snapshot is used to create shares. For read-only

file system snapshots, this property is always set to No.

Share -- A named, mountable instance of file-level storage, accessible through a file system or VMware NFS Datastore. Each share is accessible through the protocol (NFS or SMB) defined for the file system where it resides.

Question 5

What is maximum amount of time allowed when saving a configuration from the Collect Service Information menu from Unsphere in order to avoid a time-out?

A45 minutes

B60 minutes

C90 minutes

D120 minutes

Answer : B

Question 6

What are characteristics of the LUN Snapshot Copy operation?

AParent cannot be a snapshot copyCan only copy a detached snapshotHas an independent Retention Policy from the parent

BParent can be a snapshot copyCan only copy a detached snapshotHas an independent Retention Policy from the parent

CParent can be a snapshot copyCan copy an attached or detached snapshotInherits the parent Snapshot Retention Policy

DParent cannot be a snapshot copyCan copy an attached or detached snapshotInherits the parent Snapshot Retention Policy

Answer : D

The Snapshot Copy operation will make a copy of an existing snapshot that is either attached or detached from a host. The copy will capture the existing data state of the snapshot it copies. In this Copy example, a copy of an existing 4 o clock snapshot is being made. The copy inherits the parent snapshot data state of 4 o clock and its retention policy

Question 7

A Unity system LUN has a daily snapshot schedule with a Retention Policy of seven days. A hardware failure results in a double fault of the LUN.

Which snapshot behavior will be experienced?

AAll of the snapshots will be unavailable to restore data from

BData restoration is available from the oldest snapshot, all others are unavailable

CAll of the snapshots will be available to restore data from

DData restoration is available from the newest snapshot, all others are unavailable

Answer : D

The oldest snapshots residing on that pool with retention policy set to pool automatic deletion begin being deleted.
