Question 1

You have set up SnapMirror relationships between two clusters. SnapMirror shows as unhealthy and fails with the following error:

Reason: 'Transfer failed'. Last Transfer Error Was 'The number of Snapshot copies on destination volume "volume_name" has reached the maximum supported count of .

When you check the EMS logs, you notice the following:

[NetAppProdVault-01: worker_thread_342: sm.xfer.fail.maxlim.snap:alert]: The number of Snapshot copies on destination volume 'SVM_filer02:vflsystems_sm_4' of the relationship with relationship UUID 'ala620fc-a870-lle9-94ef-00a09893ee91' and policy 'filer02_vault_daily_policy' has reached the maximum supported.

[NetAppProdVault-01: sm_logger_main: smc.snapmir.update.fail:error]: Snapmirror update from source volume 'vol1' to destination volume 'vol2' failed with error 'The number of Snapshot copies on destination volume "vol2" has reached the maximum supported count of .'. Relationship UUID 'ala620fc-a870-lle9-94ef-00a09893ee91'.

What is the cause of this situation, and how can you avoid this in the future? (Choose two.)

Correct Answer: A. Modify the SnapMirror policy's -keep parameter.; D. The SnapMirror relationship has reached its maximum number of snapshots, which is 255.
Explanation:

The SnapMirror destination volume has hit the maximum allowed number of Snapshot copies, which is typically 255 for most ONTAP systems. This causes transfers to fail with a 'Snapshot copy limit reached' error.

To avoid this issue in the future:

Adjust the -keep parameter in the SnapMirror policy to control how many Snapshot copies are retained.

Implement a retention policy that matches your schedule and storage capacity.


Question 2

An administrator needs to maintain 10 snapshots per volume on a NetApp AFF system and replicate to a destination with a snapshot retention of 120.

Which NetApp feature should the administrator use?

Correct Answer: D. SnapMirror
Explanation:

SnapMirror supports asymmetric snapshot retention, allowing the source volume (on the AFF system) to retain 10 snapshots while the destination retains up to 120 snapshots. This is useful for long-term retention or compliance at the destination without consuming extra capacity on the source.


Question 3

Which two of the following need to be enabled to use tamper-proof Snapshot copies? (Choose two.)

Correct Answer: A. Compliance Clock; D. NetApp ONTAP One license
Explanation:

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.


Question 4

What ensures that data is continuously secure and encrypted in-flight?

Correct Answer: C. Transport Layer Security (TLS)
Explanation:

TLS (Transport Layer Security) ensures that data is encrypted in-flight, meaning during transmission between systems. It protects data against eavesdropping and tampering as it moves over the network.


Question 5

Which two NetApp supported products can be used to protect Kubernetes workloads? (Choose two.)

Correct Answer: A. BlueXP backup and recovery; B. Astra Control
Explanation:

BlueXP backup and recovery provides Kubernetes-aware backup and recovery capabilities.

Astra Control is a NetApp product specifically designed to manage and protect Kubernetes workloads by providing application-aware backup, snapshot, and replication features.


Question 6

Your customer replicates between two on-premises NetApp ONTAP clusters with an hourly schedule. Two days ago they made network changes, and nobody checked the ONTAP clusters. Today they notice a SnapMirror replication lag time of two days. To avoid this happening again, they want to receive an email alert if the replication lag time will be more than 1.5 hours.

Which NetApp tool can send a lag threshold alert?

Correct Answer: D. Active IQ Unified Manager
Explanation:

Active IQ Unified Manager can monitor SnapMirror relationships and generate email alerts based on lag threshold policies. You can configure it to trigger an alert when the replication lag exceeds 1.5 hours, helping prevent unnoticed replication issues.


Question 7

You are at a customer site and assisting with testing a sudden site disaster scenario with their MetroCluster solution. All the equipment at the production site is suddenly powered off, and the command metrocluster switchover -forced-on-disaster true is issued. After the switchover to the disaster site is complete, the customer notices that one of their database applications is offline. All other data is accessible from the disaster site. You notice the following in the volume show output:

What can you do to help bring the application online while in switchover?

Correct Answer: C. Modify the -in-nvfailed-state option using the volume modify command.
Explanation:

The in-nvfailed-state: true indicates that the volume is in Nonvolatile RAM (NVRAM) failed state, which happens when write operations could not be committed properly during a disaster event. This causes the volume to go into a read-only protected mode to avoid data corruption.

To restore access, you must manually override this state with:

volume modify -vserver SVM1-mc -volume APP02_DB -in-nvfailed-state false

This will bring the volume out of failed state and allow the database application to function again during the switchover.


Question 8

A ransomware attack has compromised all files on a CIFS share. The volume had a retention policy of five daily Snapshot copies, but unfortunately, no Snapshot copies were available. It was confirmed that the cybercriminal accessed only the share and did not gain access to the NetApp ONTAP cluster.

What command should be executed to prevent the quick restore strategy from being compromised?

Correct Answer: C. volume modify -snapdir-access false
Explanation:

Setting snapdir-access to false prevents users accessing the CIFS/NFS share from viewing or deleting Snapshot copies via the .snapshot directory. This secures the Snapshot restore mechanism from being exposed or tampered with in case of another attack through file shares.


Question 9

Your customer set up a SnapMirror synchronous relationship between two sites. They want to convert it to a SnapMirror active sync configuration for availability reasons.

What action must you take before you convert this relationship?

Correct Answer: C. Unmap all LUNs on the destination volumes.
Explanation:

Before converting a SnapMirror Synchronous relationship to SnapMirror active sync, you must unmap all LUNs on the destination volumes. This is required to avoid access conflicts, as SnapMirror active sync introduces active-active multipath access and centralized coordination of LUN presentation.


Question 10

You have a large 2PiB flexgroup that will need to be failed over to a DR site for a weekend due to maintenance work at the original site. To speed up time to return to normal operations the Storage Administrator will use the -quick-resync true option when reversing the SnapMirror relationship.

What needs to be taken into consideration when it comes to using quick resync?

Correct Answer: D. All storage efficiencies will be lost on the source
Explanation:

When using the -quick-resync true option in SnapMirror, storage efficiencies such as deduplication and compression are not preserved on the original source during resync. This means that efficiencies will be lost on the source volume, and data will be rehydrated to its full form during transfer.
