When backing up on-premises NetApp ONTAP volumes to tape using NDMP, which two engines are supported by ONTAP software? (Choose two.)
Correct Answer: B, D
When using NDMP (Network Data Management Protocol) to back up ONTAP volumes to tape, ONTAP supports two backup engines:
● SMTape: Used for block-level backups.
● dump: Used for file-level backups.
These are the only engines supported by ONTAP for NDMP-based tape backups.
An administrator wants to automatically prevent volumes that are used in a SnapMirror relationship from
running out of space.
Which of the following volume snapshot autodelete modify parameters would ensure that this goal can be
accomplished?
Correct Answer: C
Setting -commitment try on the volume snapshot autodelete modify command allows ONTAP to automatically delete eligible Snapshot copies
when a volume is running low on space, but only if it can do so without violating SnapMirror or retention policies. This ensures volumes in
SnapMirror relationships stay healthy and do not run out of space unexpectedly.
What two types of Compliance Clocks are available on NetApp ONTAP software? (Choose two.)
Correct Answer: A, D
NetApp ONTAP supports two types of Compliance Clocks for write once, read many (WORM) and SnapLock compliance:
The system Compliance Clock is maintained at the cluster level and ensures tamperproof retention.
The volume Compliance Clock is specific to SnapLock volumes and is used to enforce retention periods at the volume level.
A VMware Administrator needs to restore a VM after a recent server patch update has corrupted the VM operating system.
What is the quickest way to restore the VM?
Correct Answer: C
Creating a FlexClone from a pre-patch Snapshot is the quickest, space-efficient method to restore a single VM without affecting
others in the datastore. It enables immediate access to the VM’s previous state without a full
restore or rollback of the entire volume.
Which two of the following need to be enabled to use tamper-proof Snapshot copies? (Choose two.)
Correct Answer: A, B
To use tamper-proof Snapshot copies (e.g., SnapLock-based WORM Snapshots):
● The Compliance Clock must be initialized to enforce retention periods that cannot be bypassed.
● A NetApp ONTAP One license includes the SnapLock feature, which enables tamper-proof snapshot functionality.
