Network Appliance NetApp Accredited Hardware Support Engineer Sample Questions (Q24-Q29):

NEW QUESTION # 24
Which two scenarios are common causes of the root volume needing root volume recovery? (Choose two.)

A. The root volume ran out of space.
B. The mainboard was replaced following a Non-Maskable Interrupt (NMI) panic.
C. Root volume migrate was performed.
D. The cluster configuration is out of sync on the volume.

Answer: A,B

Explanation:
* If the root volume runs out of space, it can cause operational issues and require recovery.
* The root volume must always have sufficient space for system logs, configuration files, and core dumps.
1. Root Volume Ran Out of Space:
* When a mainboard is replaced, the system configuration stored in the root volume may need to be restored or recovered.
2. Mainboard Was Replaced Following an NMI Panic:
* C. Root volume migrate was performed:
* Root volume migration is a normal operation and does not typically cause the need for root volume recovery.
* D. The cluster configuration is out of sync on the volume:
* While this can cause configuration issues, it does not directly lead to root volume recovery.
Why Other Options Are Incorrect:
* "ONTAP Root Volume Management Guide" explains scenarios leading to root volume issues and recovery procedures.

NEW QUESTION # 25
You have upgraded your cluster from ONTAP 9.5 software to ONTAP 9.7 software. After two days, you notice that the upgrade is causing issues. You decide to revert to ONTAP 9.5 software.
Which two actions do you need to complete before you revert? (Choose two.)

A. Wipe your config and restore from backup.
B. Delete all Snapshot copies from the past two days.
C. Reinstall your boot media and install ONTAP 9.5 software.
D. Revert from ONTAP 9.7 software to ONTAP 9.6 software and then to ONTAP 9.5 software.

Answer: A,C

Explanation:
Reverting to a previous ONTAP version requires careful preparation because ONTAP upgrades often introduce irreversible changes. To successfully revert, the following actions are needed:
* C. Reinstall your boot media and install ONTAP 9.5 software
* Explanation:You need to reinstall the older version of ONTAP (9.5) on the boot media because the current version (9.7) has been installed as part of the upgrade. The reinstallation ensures that the system boots with ONTAP 9.5.
* Steps:
* Boot the node into maintenance mode.
* Perform the reinstallation using the appropriate ONTAP 9.5 image.
* D. Wipe your config and restore from backup
* Explanation:A revert requires wiping the configuration because ONTAP upgrades may have made changes to the cluster configuration or WAFL metadata. Restoring the configuration from a backup ensures consistency with the older ONTAP version.
* Steps:
* Back up the current cluster configuration before proceeding.
* Use the restored backup after the revert is complete to reconfigure the system.
Why the Other Options Are Incorrect:
* A. Revert from ONTAP 9.7 software to ONTAP 9.6 software and then to ONTAP 9.5 software:
* Incorrect. ONTAP reverts must directly target the desired version. You cannot perform multi-step reverts.
* B. Delete all Snapshot copies from the past two days:
* Incorrect. Deleting Snapshot copies is not a prerequisite for reverting ONTAP. While older Snapshot copies might not be compatible with the reverted version, they do not need to be deleted before the revert.
References:
* NetApp Documentation: ONTAP Upgrade and Revert Procedures.
* NetApp Knowledge Base: Steps for reinstallation and configuration restoration during a revert.

NEW QUESTION # 26
Which of the following scenarios could result in a NetApp WAFL inconsistency in a RAID DP aggregate?

A. rebooting a node during a disk reconstruction
B. two disks failing and a block error during reconstruction
C. two disks failing within seconds of each other
D. both party disks failing

Answer: B

Explanation:
A NetApp WAFL (Write Anywhere File Layout) inconsistency in a RAID-DP aggregate could occur in the following scenarios:
* Why this causes inconsistency:
* RAID-DP is designed to handle up to two concurrent disk failures. However, if a block error occurs during the reconstruction process (e.g., unreadable data on the surviving disks), the RAID group cannot rebuild the lost data, leading to WAFL inconsistencies.
1. Two disks failing and a block error during reconstruction
* Why this causes inconsistency:
* If two disks in the same RAID group fail nearly simultaneously (before the RAID-DP can reconstruct data from the first failed disk), the system cannot recover the data, resulting in WAFL inconsistencies.
2. Two disks failing within seconds of each other
* B. rebooting a node during a disk reconstruction:
* Rebooting a node does not cause WAFL inconsistency because ONTAP ensures that RAID reconstructions resume upon reboot without data loss.
* D. both party disks failing:
* This is not a valid RAID-DP term.
Why Other Options Are Incorrect:
* "WAFL and RAID-DP Operations Guide" explains failure scenarios that could cause inconsistencies.
* NetApp's "Troubleshooting RAID Groups and Aggregates" covers recovery procedures for double-disk failures and reconstruction errors.

NEW QUESTION # 27
Your customer notices that their AFF A220 high-availability (HA) system is showing Single-Path HA.

How do you make the system into multipath HA?

A. 0a and 0c on both controllers should be connected.
B. 0a and 0d on both controllers should be connected
C. 0c and 0d on both controllers should be connected.
D. 0a and 0b on both controllers should be connected.

Answer: A

Explanation:
In a NetApp high-availability (HA) configuration, multipath HA ensures redundancy by providing two independent paths from each controller to the connected storage. If the system is currently showing Single- Path HA, it means only one path is operational or connected, which is a potential single point of failure.
To convert the configuration to multipath HA, additional cabling must be configured to establish the second path. For the AFF A220 system, the correct connections are as follows:
Explanation of the Correct answer:
* AFF A220 Port Configuration for HA:
* Each controller in an AFF A220 has ports labeled 0a, 0b, 0c, and 0d for connectivity.
* In a multipath HA configuration, each controller must have two independent paths to the connected storage via the partner controller's disk shelves.
* Correct Cabling for Multipath HA:
* Port 0a on both controllers must be connected to the corresponding port (e.g., disk shelf stack or Inter-Switch Link).
* Port 0c on both controllers must also be connected to complete the redundant path.
* These connections ensure that there are two independent data paths between the controllers and the storage system, providing fault tolerance in case one path fails.
* Single-Path HA to Multipath HA:
* If the system currently shows Single-Path HA, it is likely that only one set of ports (e.g., 0a and
0b) are cabled.
* Adding the additional connections on 0a and 0c establishes the second path required for multipath HA.
Why the Other Options Are Incorrect:
* A. 0a and 0b on both controllers should be connected:
* This option only connects ports 0a and 0b, which does not establish a multipath HA configuration. Port 0c is also required for redundancy.
* C. 0c and 0d on both controllers should be connected:
* Connecting only 0c and 0d would leave ports 0a disconnected, failing to establish a proper multipath HA setup. Both 0a and 0c are required.
* D. 0a and 0d on both controllers should be connected:
* Connecting 0a and 0d is not the standard configuration for multipath HA in an AFF A220 system. Port 0c is part of the required configuration.
How to Verify the Configuration:
* Use the following ONTAP command to verify the HA status:
cluster::> storage failover show -fields multipath-ha
* This will display whether the system is in multipath HA or single-path HA mode.
* Check the port connectivity:
cluster::> network port show -node <node_name>
References:
* NetApp Hardware Installation and Setup Guide for AFF A220.
* NetApp Knowledge Base: "Configuring Multipath HA for AFF Systems."
* ONTAP 9.x System Administration Guide: "High Availability Configurations." Understanding Single-Path HA vs. Multipath HA:
* Single-Path HA indicates that only one path exists between the controllers and the connected shelves, leading to limited redundancy.
* Multipath HA requires both controllers to have redundant SAS connections to the shelves.
Cabling for Multipath HA in AFF A220 Systems:
* To achieve multipath HA, you must connect 0c and 0d on both controllers to the appropriate stack ports on the shelves.
* This ensures dual paths for each controller to access the storage shelves.
NetApp Reference Documentation:
* Refer to the "ONTAP Multipath HA Configuration Guide" and the "NetApp Hardware Installation Guide" for AFF A220 systems for cabling diagrams and best practices.

NEW QUESTION # 28
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 -diagnostic
B. Download via Service Processor Infrastructure (SPI) and upload to upload.netapp.com.
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.
