NEW QUESTION # 45
During which two operations is the NVRAM replayed by the high-availability (HA) partner? (Choose two.)

A. when a node is halted
B. during a negotiated takeover
C. after triggering a sync core
D. when the node loses power

Answer: B,D

Explanation:
* Description:
* When a negotiated takeover occurs (e.g., for maintenance or upgrades), NVRAM data is replayed by the HA partner to ensure no data is lost.
* Relevance:
* This ensures that all pending writes are safely processed by the partner node.
1. During a Negotiated Takeover:
* Description:
* If a node loses power unexpectedly, the HA partner replays the mirrored NVRAM data to protect active write operations.
2. When the Node Loses Power:
* A. after triggering a sync core:
* Triggering a sync core does not involve NVRAM replay; it captures the system state for debugging.
* B. when a node is halted:
* Halting a node does not trigger NVRAM replay unless it is part of a negotiated takeover.
Why Other Options Are Incorrect:
* "ONTAP High Availability Guide" explains NVRAM mirroring and replay during failover scenarios.

NEW QUESTION # 46
Which two NetApp tools should be used when troubleshooting the root cause of an unexpected controller reboot? (Choose two.)

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

Answer: B,E

Explanation:
To troubleshoot the root cause of an unexpected controller reboot, the following tools are commonly used:
* 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.
1. Active IQ Unified Manager
* 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.
2. ONTAP CLI
* B. Active IQ Digital Advisor:
* This tool focuses on predictive analytics and proactive recommendations, not troubleshooting unexpected reboots.
* D. ONTAP Mediator:
* This tool is used for managing MetroCluster configurations, not for troubleshooting reboots.
* E. Active IQ Config Advisor:
* This tool checks for configuration best practices but does not provide detailed logs or reboot diagnostics.
Why Other Options Are Incorrect:
* NetApp "ONTAP System Management Guide" emphasizes the use of Unified Manager and CLI for troubleshooting system issues.

NEW QUESTION # 47
How do you set environment variables to factory settings?

A. setenv factory
B. unsetenv all
C. wipeconfig
D. set-defaults

Answer: D

Explanation:
To reset environment variables to factory settings, the set-defaults command is used. This command clears all customizations and restores the environment variables to their default values.
* Command Syntax:At the LOADER prompt, type:
Key Details:arduino
Copy code
set-defaults
* Effect:This command resets all environment variables (e.g., boot arguments, diagnostic settings) to their original factory defaults.
* B. unsetenv all:
* This command clears all environment variables, but it does not restore them to factory defaults.
* C. setenv factory:
* This is not a valid command in NetApp systems.
* D. wipeconfig:
* This command is used to clear configuration and logs but does not reset environment variables.
Why Other Options Are Incorrect:
* NetApp "System Configuration Guide" confirms the use of set-defaults for restoring environment variables to factory settings.

NEW QUESTION # 48
While performing a health check on a cluster, you notice the following entries in the cluster event log:

Referring to the exhibit, which of the following actions do you take?

A. Sanitize the disk.
B. Review the current firmware and known issues.
C. Reseat the disk.
D. Use diskcopy to copy the disk to a working spare.

Answer: B

Explanation:
Analyzing the Error in the Event Log:
* The log entry indicates a medium error on a disk, suggesting an unrecoverable read issue.
* While the RAID subsystem attempts to reconstruct unreadable data, this error might indicate a firmware issue or a compatibility problem with the disk.
Why Reviewing Firmware and Known Issues Is Important:
* Medium errors can sometimes result from outdated or incompatible firmware.
* By reviewing firmware release notes and known issues for the disk model (NETAPP X381_HLBRE10TSDB in this case), you can identify if this is a known issue and resolve it by updating the firmware.
Other Options:
* Sanitize the disk (Option A): Not relevant here, as sanitization is used for secure data erasure.
* Reseat the disk (Option B): Useful for addressing hardware seating issues, but not the first step here.
* Diskcopy to a spare (Option D): This is a last-resort recovery step and not the primary action.
NetApp Reference Documentation:
* "ONTAP Disk Management Guide" and "Disk Firmware Release Notes" detail how to handle medium errors and update firmware.

NEW QUESTION # 49
Which two commands confirm whether an aggregate is WAFL inconsistent? (Choose two.)

A. node run -node <node> sysconfig -r
B. node run -node <node> sysconfig -a
C. storage aggregate show
D. wafiron show <aggregate>

Answer: A,D

Explanation:
To determine whether an aggregate is WAFL (Write Anywhere File Layout) inconsistent, the following two commands can be used:
* What it does:This command directly checks the WAFL consistency status of the specified aggregate. If an aggregate is WAFL inconsistent, it will report the inconsistency in the output.
* How to use:
* Run the command: wafiron show <aggregate> (replace <aggregate> with the name of the aggregate).
* Look for indications of WAFL inconsistency in the output.
* Why it's relevant:The wafiron utility is specifically designed to provide WAFL status and diagnostics.
It is the most accurate and direct way to confirm whether an aggregate is inconsistent.
* References:
* "WAFL Troubleshooting Guide" from NetApp highlights the wafiron show command as a primary tool for checking aggregate consistency.
1. wafiron show <aggregate>
* What it does:This command displays RAID information for all aggregates on the specified node. If an aggregate is WAFL inconsistent, it will be explicitly mentioned in the output.
* How to use:
* Run the command: node run -node <node> sysconfig -r.
* Check the output for the phrase "WAFL inconsistent" under the corresponding aggregate.
* Why it's relevant:This command provides additional context, such as the RAID group details, which can help understand whether the inconsistency is isolated or part of a larger issue.
* References:
* "ONTAP CLI Commands Guide" specifies sysconfig -r as a method to verify aggregate status, including WAFL consistency.
2. node run -node <node> sysconfig -r
* C. storage aggregate show:
* This command displays aggregate configuration and usage information but does not report WAFL inconsistency.
* D. node run -node <node> sysconfig -a:
* While this command shows detailed hardware configuration information, it does not include WAFL consistency status for aggregates.
