Questions # 1:

What two types of Compliance Clocks are available on NetApp ONTAP software? (Choose two.)

Options:

volume

SVM

NTP

system

Answer

A, D

Explanation

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.

Questions # 2:

What is the minimal interface requirement for a SnapMirror relationship between clusters?

Options:

one data LIF per SVM

one cable directly connected to both clusters

one intercluster LIF per node

one intercluster LIF per SVM

Answer

Explanation

For a SnapMirror relationship to function properly, each node in a cluster must have at least one intercluster LIF. These LIFs are used exclusively for replication traffic and ensure that all nodes can participate in SnapMirror operations.

Questions # 3:

You have two sites running NetApp ONTAP 9.14.1 clusters that have databases connecting through FC that have a near-zero RTO requirement.

What NetApp solution would allow a failover between the sites with a near-zero RTO?

Options:

BlueXP

SnapMirror SVM

SVM data mobility

SnapMirror active sync

Answer

Explanation

SnapMirror active sync provides active-active synchronous replication for SAN workloads (including FC-attached databases), ensuring zero RPO and near-zero RTO. It enables automatic failover and failback between sites, making it the ideal solution for mission-critical applications requiring continuous availability.

Questions # 4:

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?

Options:

volume autosize -autogrow disable

security multi-admin-verify modify -enabled true

volume modify -snapdir-access false

volume snapshot -autodelete disabled

Answer

Explanation

Settingsnapdir-accessto false prevents users accessing the CIFS/NFS share from viewing or deleting Snapshot copies via the.snapshotdirectory. This secures the Snapshot restore mechanism from being exposed or tampered with in case of another attack through file shares.

Questions # 5:

You have three clusters and want to set up a data protection relationship between Cluster1 and Cluster2 and also between Cluster1 and Cluster3. You want to make sure that the traffic between these two relationships is separated.

What must be configured on Clusterl to enable cluster peering with the other two clusters?

Options:

broadcast domains

IPspaces

VLANs

interface groups

Answer

Explanation

To separate traffic for different cluster peering relationships on the same cluster (Cluster1), you need to configure IPspaces. IPspaces allow multiple logical network domains within a single ONTAP cluster, ensuring that peering traffic to Cluster2 and Cluster3 remains isolated.

Questions # 6:

Your customer is running NAS & SAN workloads on an old two node ONTAP Cluster, which reached end of support. As their business is growing, they need a new solution which can provide continuous availability and an automatic switchover for all of his workloads. They already have two data centres that are about 400km apart.

Which solution meets this requirement?

Options:

MetroCluster IP

MetroCluster FC

SnapMirror SVM replication

SnapMirror active sync

Answer

Explanation

MetroCluster IP is the ideal solution for continuous availability and automatic switchover of both NAS and SAN workloads across geographically separated data centers (up to 700 km apart). It provides synchronous replication with automatic disaster recovery capabilities, making it the best fit for this scenario.

Questions # 7:

When backing up on-premises NetApp ONTAP volumes to tape using NDMP, which two engines are supported by ONTAP software? (Choose two.)

Options:

tar

SMTape

cpio

dump

Answer

B, D

Explanation

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.

Questions # 8:

You have created a SnapMirror relationship from your production volume serving SMB/CIFS data to your DR cluster. After two days of updates, you do not see any of the expected snapshots on the secondary volume.

Why is SnapMirror failing to replicate snapshots?

Options:

The SnapMirror label is missing from the SnapMirror policy on the secondary volume.

SnapMirror is not properly licensed.

SVM peering is not properly configured.

The SnapMirror label is missing from the snapshot policy on the secondary volume.

Answer

Explanation

SnapMirror replication is driven by labels that match between the snapshot policy on the source volume and the SnapMirror policy. If the snapshot policy on the source does not include the correct SnapMirror label, SnapMirror will not recognize which snapshots to replicate, resulting in no transfers.

Questions # 9:

An administrator has been tasked to replicate data between two NetApp clusters to ensure that the data is replicated no more than once per hour.

Which NetApp solution meets this requirement?

Options:

MetroCluster SyncMirror

SnapMirror active sync

SnapMirror Synchronous

SnapMirror Asynchronous

Answer

Explanation

SnapMirror Asynchronous is designed to replicate data based on a scheduled interval, such as once per hour. It is ideal for disaster recovery scenarios where zero RPO is not required but periodic replication is sufficient.

Questions # 10:

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

Options:

NetApp Volume Encryption (NVE)

NetApp Aggregate Encryption (NAE)

Transport Layer Security (TLS)

Onboard Key Manager (OKM)

Answer

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.
