Network Appliance NetApp Accredited Hardware Support Engineer Sample Questions (Q32-Q37):

NEW QUESTION # 32
Which RAID type provides protection against three disk failures?

A. RAID 5
B. RAID 4
C. RAID DP
D. RAID-TEC

Answer: D

Explanation:
RAID-TEC Overview:
* RAID-TEC (Triple Erasure Coding) is a NetApp RAID technology designed to protect against up to three simultaneous disk failures.
* It is ideal for systems with high-density disks or workloads requiring extreme fault tolerance.
Why RAID-TEC Is Correct:
* RAID-TEC uses triple-parity protection, which provides redundancy against three disk failures, making it more resilient than RAID-DP or RAID 5.
* RAID-DP only protects against two disk failures, while RAID 4 and RAID 5 protect against a single failure.
NetApp Reference Documentation:
* "NetApp RAID and Data Protection Guide" details the differences between RAID-DP and RAID-TEC, highlighting RAID-TEC's ability to tolerate three failures.

NEW QUESTION # 33
A node has panicked with a PCI/NMI error. Giveback has not been performed.
Which two commands should you run to collect the logs to determine the cause? (Choose two.)

A. show pci -v
B. pelog -a -g=2
C. event log show
D. rdfile /mroot/etc/log/SSRAM

Answer: B,D

Explanation:
To diagnose a PCI/NMI error and collect logs, use the following commands:
* What it does:This command collects PCI error logs, including detailed information about PCI devices and the errors that caused the panic.
* How to use:Run the command from the nodeshell to capture the required PCI log entries.
1. pelog -a -g=2
* What it does:This command reads the SSRAM log file, which contains low-level error information related to PCI and other hardware subsystems.
* How to use:Run the command to view the log entries directly for detailed troubleshooting.
2. rdfile /mroot/etc/log/SSRAM
* B. show pci -v:
* While this command displays PCI device information, it does not provide detailed error logs.
* D. event log show:
* This displays event log entries but does not contain the specific PCI or NMI-related logs required for diagnosing the panic.
Why Other Options Are Incorrect:
* "ONTAP Hardware Troubleshooting Guide" lists pelog and SSRAM as tools for analyzing PCI errors.
* "ONTAP Panic Analysis Guide" emphasizes the importance of collecting detailed hardware logs.

NEW QUESTION # 34
What is the default amount of time that a volume is available for recovery from the volume recovery queue following a volume deletion?

A. 24 hours
B. 12 hours
C. 72 hours
D. 48 hours

Answer: B

Explanation:
When a volume is deleted in a NetApp ONTAP system, it is placed in the Volume Recovery Queue. By default, the volume remains in this recovery queue for 12 hours before being permanently deleted. This allows administrators to recover mistakenly deleted volumes within the set retention period.
Explanation of Default Behavior:
* Volume Recovery Queue:
* This is a feature in NetApp ONTAP that acts as a safety mechanism, providing a grace period for recovering deleted volumes.
* The default retention period for volumes in the recovery queue is 12 hours, as confirmed by the NetApp KB: "How to use the Volume Recovery Queue."
* How to Recover a Deleted Volume:
* Administrators can recover a deleted volume as long as it remains in the recovery queue and the retention period has not expired.
* Use the ONTAP CLI command:
arduino
Copy code
cluster::> volume recovery-queue recover -vserver <vserver_name> -volume <volume_name>
* This command restores the volume back to its original state.
* How to Check the Volume Recovery Queue:
* To view volumes in the recovery queue and their expiration times, use:
arduino
Copy code
cluster::> volume recovery-queue show
* Changing the Default Retention Period:
* While the default period is 12 hours, it can be adjusted by administrators to fit specific organizational requirements. This is done via system settings or policies.
Why the Other Options Are Incorrect:
* B. 48 hours: Incorrect. The default retention period is not 48 hours; it is 12 hours by default.
* C. 72 hours: Incorrect. While a custom configuration could allow this, it is not the default.
* D. 24 hours: Incorrect. Although this was previously thought to be the default, NetApp documentation explicitly states it is 12 hours.
References:
* NetApp Knowledge Base Article: "How to use the Volume Recovery Queue".
* NetApp ONTAP Documentation: Volume Recovery and Data Management Procedures.

NEW QUESTION # 35
What is the recommended value for disk and CPU use when you plan an upgrade?

A. less than 50%
B. less than 90%
C. less than 85%
D. less than 70%

Answer: D

Explanation:
Upgrade Considerations for Disk and CPU Utilization:
* During an ONTAP upgrade, it is critical to ensure the system has sufficient resources to handle the upgrade process without impacting normal operations.
Recommended Threshold:
* NetApp recommends that both disk and CPU utilization should be below 70% before initiating an upgrade. This ensures that there is enough headroom for the upgrade operations and avoids performance degradation.
Steps to Verify Utilization:
* Use the system node show -fields cpu command to check CPU usage.
* Use the storage aggregate show -fields used command to check aggregate disk utilization.
NetApp Reference Documentation:
* "ONTAP Upgrade and Maintenance Guide" specifies the 70% threshold for disk and CPU usage during upgrade planning.
* The "ONTAP Performance Management Guide" provides methods for monitoring system resource utilization.

NEW QUESTION # 36
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. system node autosupport invoke-core-upload
B. system node autosupport invoke -diagnostic
C. Download via Service Processor Infrastructure (SPI) and upload to upload.netapp.com.
D. Download via CIFS and upload to upload.netapp.com.

Answer: A,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.
