Normally, before you split a SyncMirror volume, you ensure that both plexes are

snapshots, contain the most recent snapshot

When you issue the snapmirror status command, to what does the 'Lag' column refer?

The difference between the current time and the last basic snapshot creation time on the source for a transfer which completed successfully.

Alter a SnapRestore reversion of a volume, incremental backup and restore operations on the file or volume cannot rely on the timestamps to determine what data needs to be backed up or restored. Which one of the following is the most likely course of action to take to ensure correct incremental backups?

Perform a base-level backup of the volume after you restore it.

Reboot the storage appliance to reset timestamps back to their original times before the reversion.

Take a new snapshot of the volume to create new base-level timestamps for the incremental backup.

First perform choice c and then choice a.

Which one of the following statements is true of storage appliance SnapVault backup?

The qtree is the basic unit for SnapVault backup.

The volume is the basic unit of SnapVault backup.

The file is the basic unit for SnapVault backup.

The directory is the basic unit for SnapVault backup.

The qtree is the basic unit for SnapVault backup.

When you are setting up SnapMirror, which one of the following is not a replication pre-requisite?

The source volume must be offline.

SnapMirror must be licensed for each storage appliance.

The source volume must be offline.

If you are replicating a volume, you must create a restricted volume to be used as the SnapMirror destination volume.

The capacity of the SnapMirror destination must be greater than or equal to the capacity of the source.

Which three are true when creating a SyncMirror volume? (Choose 3)

The number of disks added must be an even number and equally divided between the two plexes.

The number of disks selected for one plex must equal the number of disks selected from the other plex.

The disks are selected first on the basis of equivalent bytes per sector (bps) size, then on the basis of the size of the disk. If there is no equivalent-sized disk, Data ONTAP takes a larger capacity disk and downsizes it.

The number of disks added must be an even number and equally divided between the two plexes.

The disks selected for Plex 0 and Plex 1 must come from the same disk pools.

The number of disks selected for one plex must equal the number of disks selected from the other plex.

The disks are selected first on the basis of equivalent bytes per sector (bps) size, then on the basis of the size of the disk. If there is no equivalent-sized disk, Data ONTAP takes a larger capacity disk and downsizes it.

In a Fabric Attached MetroCluster, a 'disaster' is described as a:

Prolonged communication disruption

Failure of the Inter-Switch-Links (ISL)

Malfunction of the Fiber Channel adapter on the cluster node

Failure of the interconnect cable

Prolonged communication disruption

A mirrored volume has a failed disk, but there are no available spares in the pool from which the degraded plex was built. Data ONTAP will:

Warn you that there are no available spares from the proper pool

Choose spare disks to reconstruct from the opposite pool

Warn you that there are no available spares from the proper pool

'Halt' after 24 hours if spare disks are not added to the proper pool

Stop all applications that are running

Which one of the following commands would you use to disable client access to snapshots on a volume called /vol/flexvoM?

vol options/vol/flexvoM nosnapdiron

vol options/vol/flexvoM nosnapdiroff

vol options/vol/flexvoM nosnapdiron

vol options/vol/flexvoM snapdiroff

vol options/vol/flexvoM snapdiron

What user-controllable security mechanism is built into OSSV?

QSM access list modifiable via svconfigurator

Contents inside a file called access and located in OSSV <installdir>/snapvault/etc

MD5 based authentication between SnapVault primary and secondary, with changeable password

Which two of the following statements apply to the fs_size_fixed volume option?

This option is automatically set to be on when a volume becomes a Snap Mirrored volume

This option causes the file system to remain the same size and not grow or shrink when a Snap Mirrored volume relationship is broken

This option is automatically set to be on when a volume becomes a Snap Mirrored volume

This option causes the file system to remain the same size and not grow or shrink when a Snap Mirrored volume relationship is broken

The option turns to off after the snapmirror break command is issued for the volume

Which one of the following statements apply to Advanced Single Instance Storage (ASIS)?

Eliminates duplicates blocks in SnapVault for NetBackup secondary volumes

Eliminates duplicates files in SnapVault for NetBackup secondary volumes

Eliminates duplicates blocks in SnapVaultfor NetBackup source volumes

Eliminates duplicates blocks in SnapVault for NetBackup secondary volumes

Eliminates duplicates files in SnapVaultfor NetBackup source volumes Correct answers

Which one of the following statements does not apply to the SnapMirror visibility-interval variable?

The default interval value is 5 minutes

This variable controls the view of the data on the destination system

By setting a value, you specify the amount of time before an automatic snapshot is created on the source volume that is synchronously mirrored

The default interval value is 5 minutes

The smallest interval value supported is 30 seconds

One week ago you performed a single file SnapRestore from a snapshot other than the most recent. You now notice that the storage appliance is now taking longer to perform snapshot deletions. Which one of the following reasons is the most likely cause of this problem?

Before a snapshot can be deleted, the active maps across all snapshots need to be checked for active blocks related to the file you restored.

Snapshots that existed after the one used for the single file SnapRestore need to be manually deleted.

The SnapRestore schedule changed from weekly to hourly.

All of the snapshots created after you did the single file SnapRestore were deleted, and reserved inodesfrom the snapshots still exist.

Before a snapshot can be deleted, the active maps across all snapshots need to be checked for active blocks related to the file you restored.

You have quiesced a volume to stabilize the contents of a destination just prior to a snapshot. What is the next logical command that you would issue after the snapshot is complete?

options snapmirror.log enable off

Which one of the following statements apply to the Free Space Estimator utility?

This utility determines if there is sufficient disk space available on the primary to perform an OSSV transfer

This utility determines if there is sufficient space on the secondary volume to perform a transfer

This utility determines if there is sufficient disk space available on the primary to perform an OSSV transfer

This utility runs automatically after each transfer

This utility must be enabled on the secondary storage system

A mirrored volume has a failed disk, but there are no available spares in the pool from which the degraded plex was built. Data ONTAP will:

Warn you that there are no available spares from the proper pool

Choose spare disks to reconstruct from the opposite pool

Warn you that there are no available spares from the proper pool

'Halt' after 24 hours if spare disks are not added to the proper pool

Stop all applications that are running

Which one of the following options will allow a snapmirror storage appliance to mirror from this system?

options snapmirror.access host = <destination_filer>

snapmirror. destination <destination_filer>

options snapmirror.allow<destination_filer>

snapmirror.access <destination_filer>

options snapmirror.access host = <destination_filer>

You want to create an automated test environment that performs a single file SnapRestore. Every time you run the procedure, however, SnapRestore prompts you to confirm your decision to revert the file. How can you automate this step?

Use the -f option with the snap restore command.

Enter the priv set advanced mode on the storage appliance and the prompt will not appear.

Enable the options snaprestore_noprompts enable=on option.

Use the -f option with the snap restore command.

These prompts are for data protection and auditing and cannot be overridden.
