NEW QUESTION # 38
You have a NetApp ONTAP cluster for which you want to reuse a disk shelf from a different cluster. You have removed the disk shelf from the first cluster, moved the shelf, and correctly cabled the shelf to the new cluster. After connecting the new disk shelf, you attempt to create a new aggregate. You receive a message stating that there are not enough disks available. You see the following results:

What action do you take to resolve this issue?

• A. Unfail the failed drives.
• B. Replace the failed drives.
• C. Remove the foreign aggregate.
• D. Correct the disk ownership.

Answer: D

Explanation:
The shelf was moved from another cluster, and the disks still contain ownership and foreign aggregate metadata. Correcting disk ownership makes the disks available to the new cluster so they can be used to create a new aggregate.

NEW QUESTION # 40
You have created a case with NetApp Support for an issue with a DS4246 shelf on an ONTAP
9.12.1 system. They have requested that you provide shelf logs. What action do you need to take to collect the shelf logs?

• A. Invoke a diagnostic autosupport with the subsystem log_files.
• B. Provide the output of the nodeshell command rdfile/etc/log/shelflog.
• C. Invoke a diagnostic AutoSupport with the subsystem storage.
• D. Invoke an autosupport of type all using Active IQ Unified Manager.

Answer: C

Explanation:
To collect shelf logs for a DS4246 shelf in an ONTAP 9.12.1 system, you must invoke a diagnostic AutoSupport specifically targeting the storage subsystem. This action ensures that detailed storage logs, including shelf logs, are included in the AutoSupport bundle.
Steps to Collect Shelf Logs:
Use the following command:
bash
Copy code
system node autosupport invoke -node <node_name> -type diagnostic -subsystem storage Replace <node_name> with the name of the node experiencing the issue.
This command generates an AutoSupport message that includes logs related to storage subsystems, such as disk shelves and adapters.
Provide the AutoSupport case number to NetApp Support for further analysis.

NEW QUESTION # 41
A Field Support engineer has just replaced the motherboard of one of the controllers in a NetApp ONTAP cluster. The node is recovered, but ONTAP software will not perform a giveback. After investigating, you determine that you are using self-encrypting FIPS drives. The failure is that the Onboard Key Manager is unable to synchronize. The passphrase has been misplaced or forgotten. Which action do you take to correct the failure while leaving the data intact?

• A. Use the storage encryption disk sanitize command.
• B. Use the storage encryption disk modify command.
• C. Use the storage encryption disk destroy command.
• D. Use the volume encryption rekey start command.

Answer: B

Explanation:
The storage encryption disk modify command is used to reassign or update encryption key information for self-encrypting drives, allowing the disks to be re-synchronized with the key management configuration while preserving the existing encrypted data.

NEW QUESTION # 42
A customer wants to minimize downtime while replacing a failed NVRAM battery in a dual- controller HA pair. Which operational state is REQUIRED before beginning the replacement?

• A. The impaired node must remain powered off for 24 hours
• B. Disk ownership must be removed manually
• C. Giveback operations should be completed or controlled properly
• D. Storage failover must be disabled permanently

Answer: C

Explanation:
Before servicing components such as NVRAM batteries, the HA environment must be stable and giveback properly managed. This prevents unexpected failover conditions and protects data availability. Permanently disabling storage failover is unnecessary. Disk ownership remains managed by ONTAP and typically does not require manual modification during standard FRU procedures.

NEW QUESTION # 43
What should be the first step taken after detecting a NetApp WAFL inconsistency?

• A. Force offline the affected aggregate.
• B. Run a dump to null.
• C. Stabilize the system.
• D. Run wafliron.

Answer: C

Explanation:
When a WAFL inconsistency is detected, the first step is to stabilize the system before attempting any repairs or recovery.
Steps to Handle WAFL Inconsistency:
Stabilize the System:
Ensure that the system is not experiencing ongoing hardware or software issues.
Avoid making changes to the affected aggregate or volume until the system is stable.
Assess the Impact:
Determine which aggregates or volumes are affected and the severity of the inconsistency.

NEW QUESTION # 44
A customer has one large aggregate over several shelves, and only one shelf has reached End of Support (EoS) and needs to be evacuated. The installation engineer already added a new shelf and assigned the disks with same type and size. Which NetApp ONTAP command is used to copy the data from disk to disk?

• A. storage disk remove
• B. storage disk replace
• C. storage disk fail -i
• D. storage aggregate relocation

Answer: B

Explanation:
The storage disk replace command copies data from a source disk to a replacement disk, allowing disks from the EoS shelf to be evacuated nondisruptively while preserving the aggregate.

NEW QUESTION # 45
An engineer needs to replace a failed NVMe SSD in an AFF system. Which handling practice is MOST important?

• A. Reboot both controllers before touching the drive
• B. Avoid anti-static precautions to speed replacement
• C. Disable AutoSupport permanently
• D. Use ESD protection during handling and installation

Answer: D

Explanation:
NVMe SSDs are sensitive electronic components vulnerable to electrostatic discharge damage.
Proper ESD protection procedures are essential during handling and replacement. Controller reboots are generally unnecessary for hot-swappable drives. AutoSupport configuration does not affect safe hardware handling practices.

NEW QUESTION # 46
A NetApp node fails to boot and displays repeated boot-loop behavior after hardware maintenance. Which troubleshooting step should be performed FIRST?

• A. Reset all cluster licenses
• B. Destroy the root aggregate
• C. Verify recently installed FRUs and cable seating
• D. Replace every disk in the shelf

Answer: C

Explanation:
After maintenance, improperly seated FRUs or disconnected cables are common causes of boot loops. Engineers should first validate hardware installation integrity before performing destructive actions. Replacing all disks or resetting licenses introduces unnecessary disruption and does not address likely root causes.

NEW QUESTION # 47
You have an air-gapped NetApp ONTAP based system that has recently had a node panic, and the node is back online. To assist in troubleshooting, the NetApp Support team has asked you to submit the core file for analysis. Which two methods do you use to access the core files from the ONTAP controllers in this environment? (Choose two.)

• A. Collect files from the SPI of the affected nodes.
• B. Use the system node coredump upload command.
• C. Use the system node autosupport invoke command.
• D. Use the system node coredump external-device command.

Answer: A,D

Explanation:
The system node coredump external-device command is used in air-gapped environments to copy core files to an external storage device for transfer and analysis. Core files can also be accessed and collected through the Service Processor Infrastructure (SPI) of the affected nodes.

PANIC: Root volume is restricted. in SK process config_thread on
release 9.16.1P5 (C) on Fri Aug 1 22:15:30 GMT 2025
What action do you take to resolve the issue?

• A. Perform wafliron from the boot menu.
• B. Replace the boot media.
• C. Boot without /etc/rc.
• D. Perform a system reset backup from the Service Processor.

Answer: A

Explanation:
The panic indicates an issue with the root volume state or WAFL consistency. Running wafliron from the boot menu repairs filesystem inconsistencies on the root volume and is the appropriate recovery action for this condition.

NEW QUESTION # 49
On an AFF A700 system, a SAS stack is connected to SAS ports 2a and 2b. The system has an additional 4-port SAS card in slot 9. How should the cabling the corrected for best practices?

• A. Use port 2b and 9d.
• B. Use port 2a and 2c.
• C. Use port 2a and 9a.
• D. Use port 2a and 9b.

Answer: C

Explanation:
Best Practices for SAS Cabling in AFF A700 Systems:
The AFF A700 system has built-in SAS ports (e.g., 2a and 2b) as well as additional SAS ports on optional SAS cards.
To ensure high availability and redundancy, it is recommended to distribute SAS connections across multiple SAS ports from different controllers or slots.
Why Port 2a and 9a Are Recommended:
Port 2a is a built-in SAS port on the AFF A700 system. Port 9a belongs to the additional SAS card in slot 9. By connecting the stack using 2a and 9a, you utilize different SAS domains (built-in controller ports and add-on card ports), providing both path redundancy and load balancing.

NEW QUESTION # 50
Which two NetApp tools should be used when troubleshooting the root cause of an unexpected controller reboot? (Choose two.)

• A. Active IQ Config Advisor
• B. ONTAP Mediator
• C. Active IQ Digital Advisor
• D. ONTAP CLI
• E. Active IQ Unified Manager

Answer: D,E

Explanation:
To troubleshoot the root cause of an unexpected controller reboot, the following tools are commonly used:
1. Active IQ Unified Manager
What it does:
Provides monitoring and performance data for the ONTAP cluster, including historical event logs that may help identify the root cause of a reboot.
2. ONTAP CLI
What it does:
The CLI allows you to gather logs and status information directly from the affected node.
Commands like event log show and system core are essential for identifying the reason behind the reboot.

NEW QUESTION # 51
A NetApp ONTAP cluster has several data aggregates that contain over 400 data volumes. The aggregates are configured to share a cloud tier to an S3 bucket. All volumes use an automatic policy that moves cold data older than seven days to the object store. During an S3 provider outage, the customer was unable to access their cold data. Which action prevents downtime for each volume when the S3 provider has another outage?

• A. Configure a mirrored aggregate with the SyncMirror feature.
• B. Configure FabricPool mirroring.
• C. Configure an SVM SnapMirror relationship.
• D. Configure a volume SnapMirror relationship.

Answer: B

Explanation:
FabricPool mirroring provides a secondary object store for the cloud tier. If the primary S3 provider becomes unavailable, ONTAP can continue accessing cold data through the mirrored object store, preventing downtime for the volumes.

NEW QUESTION # 52
Which NetApp ONTAP CLI command is used to identify a failed disk that is part of an aggregate?

• A. storage disk fail
• B. disk show -broken
• C. storage show fault
• D. disk option show

Answer: B

Explanation:
The disk show -broken command displays disks that ONTAP has marked as broken or failed, including disks that belong to aggregates and require replacement or recovery actions.
