Network Appliance NetApp Accredited Hardware Support Engineer Sample Questions (Q31-Q36):

NEW QUESTION # 31
You have upgraded your cluster from ONTAP 9.5 software to ONTAP 9.7 software. After the upgrade, you notice that the upgrade causes issues. You decide to revert to ONTAP 9.5 software.
Which revert step is allowed?

A. Revert from ONTAP 9.7 software to ONTAP 9.5 software by using the boot backup procedure.
B. Revert from ONTAP 9.7 software to ONTAP 8.6 software and then to ONTAP 9.5 software.
C. Revert directly from ONTAP 9.7 software to ONTAP 9.5 software.
D. Revert to ONTAP 9.5 software with the netboot procedure.

Answer: D

Explanation:
Reverting to a Previous ONTAP Version:
* Reverting ONTAP software requires specific procedures and is only supported if the ONTAP version being reverted to is compatible with the current cluster configuration.
Why the Netboot Procedure Is Used:
* The netboot process loads the desired ONTAP version directly into memory from a network location and reinitializes the system.
* This method is used when a full software revert is required and is often necessary for downgrades to a version that cannot be directly reverted to from the running ONTAP version.
Key Notes:
* A direct revert is not supported from ONTAP 9.7 to ONTAP 9.5 using standard methods due to system metadata changes.
* Always verify compatibility using the "ONTAP Software Version Interoperability Matrix".
NetApp Reference Documentation:
* Refer to the "ONTAP Revert/Downgrade Guide" for specific instructions on using the netboot procedure.

NEW QUESTION # 32
What are two valid options for uploading a core file from a node that is running ONTAP 9.12.1 software to NetApp for analysis? (Choose two.)

A. Download via Service Processor Infrastructure (SPI) and upload to upload.netapp.com.
B. system node autosupport invoke -diagnostic
C. system node autosupport invoke-core-upload
D. Download via CIFS and upload to upload.netapp.com.

Answer: C,D

Explanation:
Options for Uploading Core Files:
* Core files are diagnostic dumps created during system failures for analysis by NetApp Support.
* They can be uploaded via multiple methods, depending on system configuration and access:
Option B (CIFS Download):
* Core files can be downloaded from the node using a CIFS share and then manually uploaded to upload.
netapp.com.
* This method is useful if automated processes are unavailable or connectivity is limited.
Option D (Autosupport Invoke-Core-Upload):
* The command system node autosupport invoke-core-upload automates the process of uploading the core file to NetApp.
* It uses the configured Autosupport mechanism to transfer the file to NetApp Support for analysis.
NetApp Reference Documentation:
* "ONTAP Autosupport Guide" and "ONTAP Troubleshooting Guide" provide instructions for manually and automatically uploading core files.

NEW QUESTION # 33
Which type of core file is generated when a node panics?

A. kernel core
B. sync core
C. mgwd core
D. user space core

Answer: A

Explanation:
When a node panics in ONTAP, a kernel core file is generated. This core file contains information about the kernel's state at the time of the panic and is essential for debugging system crashes.
* A kernel core file is produced during a node panic to capture information about the kernel, memory, and processes that led to the crash.
* The core file is stored on the root aggregate by default and can be uploaded to NetApp Support using the autosupport invoke-core-upload command.
Key Details:
* A. mgwd core:
* This is related to the Management Gateway daemon, which handles management traffic. It does not generate a core file during a panic.
* B. user space core:
* User space cores are generated for processes running in user space, not for kernel panics.
* C. sync core:
* Sync cores refer to synchronized cores for debugging but are not the primary type generated during a node panic.
Why Other Options Are Incorrect:
* "ONTAP Panic Troubleshooting Guide" specifies kernel core files as the output of a node panic.
* "ONTAP Core File Management Guide" details the handling of kernel core files after a crash.

NEW QUESTION # 34
After a panic, the customer asks you to explain the error "watchdog timeout." Which explanation would be appropriate?

A. A service that detects and recovers from computer malfunctions.
A hardware or software error prevents update of watchdog and it induces a system panic.
B. A service that monitors network activity and protects data.
A watchdog induces system panic to protect data if malicious activity is detected.
C. An optional software that monitors system performance.
An overloaded system fails to reset the watchdog and watchdog induces a system panic.
D. An optional component included with Active IQ Unified Manager.
It notifies a user if watchdog fails to reach the storage system within a certain period.

Answer: A

Explanation:
What Is a Watchdog Timeout?
* The watchdog is a software or hardware mechanism that monitors the system's health and ensures it is operating correctly.
* If the system fails to respond or update the watchdog timer within the specified time, the watchdog triggers a system panic to avoid further corruption or damage.
Cause of Watchdog Timeout:
* This usually occurs due to:
* A hardware failure (e.g., CPU or memory issue).
* A software bug causing a system hang or crash.
* The panic ensures the system stops operation to preserve data integrity and aid in troubleshooting.
NetApp Reference Documentation:
* "ONTAP Troubleshooting Guide" and "Core Dump Analysis Guide" provide details on interpreting watchdog timeouts and recommended actions.

NEW QUESTION # 35
Following an unexpected takeover, the taken-over node is waiting for giveback. The administrator plans to perform a giveback with the option -cfo-only true.
What happens if this option is used?

A. Only the data aggregates are sent back.
B. Only a simulation of the giveback is performed.
C. Only the root aggregate is given back.
D. Only SVM root volumes are sent back

Answer: A

Explanation:
Purpose of the -cfo-only true Option:
* This option is used during the giveback process in a NetApp cluster to control which aggregates are returned to the original node.
* By specifying -cfo-only true, only the data aggregates are given back to the original node, while the root aggregate remains with the takeover node.
Use Case:
* This command is helpful when you want to test the aggregate giveback functionality or if the root aggregate requires further investigation or maintenance before returning it to the original node.
NetApp Reference Documentation:
* The "ONTAP High-Availability Configuration Guide" and "Cluster Failover Management Guide" detail the behavior of the -cfo-only option during giveback scenarios.
