Question 381.

An administrator wants to verify whether an ONTAP volume has sufficient physical capacity for continued workload growth. Which information is most useful?

1. Capacity utilization and historical growth trends
   2. Number of DNS servers
   3. Number of SMB shares
   4. FC zone names

Correct Answer: 1

Explanation:

Current capacity utilization combined with historical growth trends helps an administrator estimate how quickly available storage is being consumed. This is more useful than examining a single point-in-time value because trend data can reveal whether consumption is stable or accelerating. Snapshot usage and storage-efficiency behavior can also provide useful context. DNS server counts, SMB share counts, and FC zone names do not indicate how quickly physical storage capacity is being consumed or when additional capacity may be required.

Question 382.

Which ONTAP feature can automatically increase a volume’s size when configured space conditions are reached?

1. SnapMirror resync
   2. Volume autosize
   3. FC zoning
   4. LIF failover

Correct Answer: 2

Explanation:

Volume autosize allows a supported ONTAP volume to grow automatically according to configured capacity conditions and limits. It can reduce the risk of logical volume space becoming exhausted unexpectedly, but sufficient underlying physical capacity must remain available. Administrators should therefore use autosize together with appropriate capacity monitoring. SnapMirror resync restores replication synchronization, FC zoning controls SAN fabric communication, and LIF failover supports network availability. Volume autosize is specifically intended for automatic adjustment of volume capacity.

Question 383.

A volume is using more space than expected even though active file data has not grown significantly. Which additional consumption should the administrator investigate?

1. DNS cache entries
   2. FC aliases
   3. Snapshot space usage
   4. NTP peers

Correct Answer: 3

Explanation:

Snapshot copies can retain blocks that are no longer part of the active filesystem, causing physical storage consumption to remain higher than expected even when active data appears stable. Administrators should review Snapshot usage, retention policies, and data-change patterns when investigating unexpected capacity growth. DNS caches, FC aliases, and NTP peers do not consume volume data capacity in the manner described. Snapshot space usage is therefore an important component of comprehensive ONTAP capacity troubleshooting.

Question 384.

Which ONTAP capability can automatically create point-in-time copies according to a recurring schedule?

1. Igroup
   2. VLAN
   3. Broadcast domain
   4. Snapshot policy

Correct Answer: 4

Explanation:

A Snapshot policy defines schedules and retention behavior for automatically created Snapshot copies on supported ONTAP storage. This enables regular point-in-time recovery points without requiring an administrator to create every Snapshot manually. The policy should reflect recovery requirements and available capacity because retained Snapshot data can consume storage. Igroups organize SAN initiators, VLANs segment Ethernet networks, and broadcast domains group network ports. Snapshot policies are therefore directly associated with scheduled point-in-time data protection.

Question 385.

A user accidentally deletes an important file from an ONTAP NAS volume. A recent Snapshot copy contains the file. What can the administrator use as the recovery source?

1. The appropriate Snapshot copy
   2. A broadcast domain
   3. An igroup
   4. A VLAN

Correct Answer: 1

Explanation:

A Snapshot copy containing the file before it was deleted can provide a suitable recovery source. Depending on the environment and recovery method, the required file can be restored from the appropriate point-in-time copy without reverting unrelated data. Administrators should identify the correct Snapshot based on when the deletion occurred. Broadcast domains and VLANs are networking constructs, while igroups organize SAN initiators. None of those objects provides a point-in-time version of the deleted file.

Question 386.

Which feature is designed to rapidly restore supported ONTAP data to the state represented by a selected Snapshot copy?

1. AutoSupport
   2. SnapRestore
   3. FabricPool
   4. QoS

Correct Answer: 2

Explanation:

SnapRestore provides rapid restoration of supported data using a selected Snapshot copy. Because the operation can replace newer data with an earlier state, administrators should carefully confirm the desired recovery point and understand the scope before proceeding. AutoSupport provides diagnostic information, FabricPool provides capacity tiering, and QoS controls workload performance. SnapRestore is therefore the appropriate technology when a supported dataset needs to be returned quickly to a previous Snapshot-based state.

Question 387.

Which ONTAP technology is used to maintain a replicated copy of data on another supported system for protection purposes?

1. Deduplication
   2. Compression
   3. SnapMirror
   4. NTP

Correct Answer: 3

Explanation:

SnapMirror provides replication between supported storage systems and is commonly used for data protection and disaster recovery. Replication schedules and policies should be aligned with recovery requirements, while relationship health and lag should be monitored to confirm that protection objectives are being met. Deduplication and compression improve storage efficiency, while NTP provides time synchronization. SnapMirror is therefore the ONTAP technology directly associated with maintaining a protected copy of data on another supported system.

Question 388.

A SnapMirror destination must be made writable so applications can use it during a disaster-recovery event. Which operation is required?

1. LIF migration
   2. Quota initialization
   3. Deduplication
   4. SnapMirror break

Correct Answer: 4

Explanation:

A SnapMirror break operation is used in an appropriate disaster-recovery workflow when a protected destination must become writable. Administrators should follow a tested recovery procedure because breaking the relationship affects subsequent synchronization and failback activities. The authoritative copy of the data must be understood before later resynchronization. LIF migration concerns networking, quota initialization concerns storage usage management, and deduplication concerns efficiency. SnapMirror break is therefore directly associated with activating a destination for writable recovery use.

Question 389.

Which value helps determine how far a SnapMirror destination is behind its source?

1. Replication lag
   2. VLAN ID
   3. RAID group width
   4. MTU

Correct Answer: 1

Explanation:

Replication lag indicates how far the destination is behind the source and is an important metric for evaluating whether a SnapMirror relationship is meeting recovery-point requirements. If lag increases beyond acceptable limits, administrators should examine relationship health, transfer schedules, network performance, and source change rates. VLAN IDs and MTU values relate to networking, while RAID group width relates to local storage protection. Replication lag is therefore the relevant measurement for evaluating the currency of replicated data.

Question 390.

Which disaster-recovery objective defines the maximum acceptable amount of data loss measured in time?

1. IOPS
   2. RPO
   3. Throughput
   4. Latency

Correct Answer: 2

Explanation:

Recovery Point Objective, or RPO, defines how much data loss an organization can tolerate, usually expressed as an amount of time. For example, an RPO can influence how frequently replication or other protection operations must occur. IOPS measures the number of storage operations per second, throughput measures data-transfer rate, and latency measures response time. RPO is therefore the appropriate concept when determining how current a protected copy needs to be following a failure or disaster.

Question 391.

Which disaster-recovery objective describes how quickly a service should be restored after an outage?

1. RAID-DP
   2. QoS
   3. RTO
   4. MTU

Correct Answer: 3

Explanation:

Recovery Time Objective, or RTO, defines the target amount of time within which a service or workload should be restored after an interruption. RTO helps organizations design recovery procedures, staffing, automation, infrastructure, and operational processes. It differs from RPO, which focuses on acceptable data loss. RAID-DP provides storage resiliency, QoS controls performance, and MTU is a networking parameter. RTO is therefore the relevant metric when evaluating how quickly service must return after an outage.

Question 392.

After resynchronizing a SnapMirror relationship, which verification is most important?

1. All VLANs use the same ID.
   2. Every qtree has identical quotas.
   3. All volumes have identical sizes.
   4. Relationship health, replication direction, and lag are appropriate.

Correct Answer: 4

Explanation:

After a SnapMirror resynchronization, administrators should confirm that the relationship is healthy, operating in the intended direction, and maintaining an acceptable replication lag. This verifies that data protection has actually been restored. The correct replication direction is particularly important after disaster-recovery operations where source and destination roles may have changed. VLAN IDs, qtree quotas, and volume sizes do not determine whether replication is healthy. Relationship status and lag provide the relevant post-resynchronization validation.

Question 393.

Which ONTAP technology creates a writable copy of supported data while initially sharing unchanged blocks with the source?

1. FlexClone
   2. RAID-TEC
   3. AutoSupport
   4. NFS

Correct Answer: 1

Explanation:

FlexClone creates writable, space-efficient copies that can initially share unchanged blocks with their source. This reduces the amount of additional physical capacity required at creation compared with making a complete independent copy. As the source and clone diverge, additional storage is consumed for changed data. RAID-TEC provides triple-parity protection, AutoSupport supplies diagnostic information, and NFS provides file-level access. FlexClone is therefore well suited to testing and development scenarios requiring writable copies.

Question 394.

Which ONTAP storage-efficiency feature reduces redundant physical blocks when identical data is stored repeatedly?

1. SnapMirror
   2. Deduplication
   3. VLAN
   4. Junction path

Correct Answer: 2

Explanation:

Deduplication reduces physical storage consumption by eliminating or avoiding redundant data blocks where supported. The amount of capacity saved depends heavily on workload characteristics because some datasets contain much more repeated information than others. Administrators should monitor actual efficiency results rather than assuming a fixed savings percentage. SnapMirror provides replication, VLANs provide network segmentation, and junction paths define NAS namespace placement. Deduplication is therefore the appropriate storage-efficiency technology for reducing duplicate block consumption.

Question 395.

Which storage-efficiency technology can reduce capacity requirements by storing compressible data in a more compact representation?

1. FC zoning
   2. LIF migration
   3. Compression
   4. Quotas

Correct Answer: 3

Explanation:

Compression reduces the amount of physical storage required for suitable data by representing it more compactly. Actual savings depend on the characteristics of the dataset because already-compressed or encrypted information may provide limited additional reduction. Compression can complement other ONTAP efficiency technologies such as deduplication. FC zoning controls SAN fabric connectivity, LIF migration concerns network-interface placement, and quotas manage storage consumption. Compression is therefore directly associated with reducing the physical size of compressible stored data.

Question 396.

Which technology should be considered when suitable inactive data needs to use supported object storage as a capacity tier?

1. SnapRestore
   2. RAID-DP
   3. Igroup
   4. FabricPool

Correct Answer: 4

Explanation:

FabricPool integrates supported object storage with ONTAP as a capacity tier. Depending on the configured tiering policy and data state, appropriate data can be moved from the local performance tier to object storage while remaining part of the ONTAP-managed dataset. SnapRestore provides recovery, RAID-DP provides double-parity protection, and igroups organize SAN initiators. FabricPool is therefore the relevant technology when administrators want to use supported object storage for appropriate colder or inactive data.

Question 397.

An administrator wants to prevent one application from consuming excessive IOPS and affecting other workloads. Which ONTAP feature should be configured?

1. QoS
   2. NTP
   3. Export policy
   4. Junction path

Correct Answer: 1

Explanation:

ONTAP QoS provides performance controls that can be applied to supported workloads. Appropriate maximum limits can help prevent one application from consuming excessive storage resources and negatively affecting other workloads. Administrators should base QoS settings on actual application requirements, performance measurements, and service objectives. NTP provides time synchronization, export policies control NFS authorization, and junction paths define NAS namespace placement. QoS is therefore the feature directly associated with controlling workload performance consumption.

Question 398.

Which metric should be examined when users report that storage operations are taking longer to complete than normal?

1. Snapshot count
   2. Latency
   3. Number of SVMs
   4. DNS TTL

Correct Answer: 2

Explanation:

Latency measures storage response time and is therefore a key metric when users report that I/O operations are taking longer than expected. Administrators should compare current latency with historical baselines and correlate it with IOPS, throughput, workload changes, and resource utilization. Snapshot counts, the number of SVMs, and DNS TTL values do not directly measure storage response time. Latency is therefore the most relevant initial performance metric for investigating slow storage operations.

Question 399.

Which metric measures how many storage operations are being processed each second?

1. RTO
   2. RPO
   3. IOPS
   4. Replication lag

Correct Answer: 3

Explanation:

IOPS measures the number of input/output operations processed per second. It helps administrators understand the operation rate generated by a workload, although it should be evaluated alongside latency and throughput for meaningful performance analysis. Different workloads can produce similar IOPS while having very different I/O sizes and response-time requirements. RTO and RPO are disaster-recovery objectives, while replication lag measures how far a protected destination is behind its source. IOPS specifically measures storage operation frequency.

Question 400.

After completing a major ONTAP storage, networking, and protection maintenance window, what is the best final operational check?

1. Delete all historical performance data.
   2. Disable AutoSupport until the next maintenance window.
   3. Move every data LIF to one node.
   4. Verify cluster health, client access, performance, capacity, protection relationships, and significant alerts.

Correct Answer: 4

Explanation:

A comprehensive post-maintenance validation should confirm that the cluster and nodes are healthy, clients can access required storage, performance remains within expected ranges, capacity is normal, and protection relationships are functioning correctly. Administrators should also review significant events and alerts for unresolved conditions. Deleting historical data, disabling AutoSupport, or concentrating all data LIFs on one node would reduce visibility or resiliency. A broad operational check provides evidence that the maintenance completed successfully without leaving hidden service problems.
