質問 # 43
Which two tools can be used to recover an inconsistent aggregate? (Choose two.)
正解：A、B
解説：
To recover an inconsistent aggregate, the following tools can be used:
* What it does:This tool is used to perform a consistency check on WAFL metadata. It identifies and attempts to fix WAFL inconsistencies in aggregates.
* When to use:Run wafl_check after identifying WAFL inconsistencies to repair minor metadata issues.
1. wafl_check
* What it does:This tool repairs WAFL inconsistencies by reconstructing metadata. It is more powerful than wafl_check and should only be run under NetApp Support guidance, as improper use can result in data loss.
* When to use:Use wafliron for severe WAFL inconsistencies that cannot be resolved by wafl_check.
2. wafliron
* A. file check:
* This is not a valid NetApp tool.
* C. wafl snapiron:
* While similar in name, snapiron is used for snapshot recovery, not aggregate recovery.
Why Other Options Are Incorrect:
* "ONTAP Aggregate Troubleshooting Guide" details the usage of wafl_check and wafliron.
* NetApp Support documentation provides guidelines for recovering inconsistent aggregates.

質問 # 44
On a NetApp FAS9000 system, which two field replaceable units (FRUs) are supported for replacement without takeover? (Choose two.)
正解：A、B
解説：
FRUs on FAS9000 Supporting Replacement Without Takeover:
* A (I/O Module): I/O modules can be replaced hot (without takeover) to maintain system uptime during hardware servicing.
* D (NVRAM Module): NVRAM modules on FAS9000 can also be replaced without a node takeover, ensuring data integrity during replacement.
Why Other Options Are Incorrect:
* B (DCPM Module): The DCPM (Data Center Power Management) module is not hot-swappable and requires a node takeover.
* C (Caching Module): The caching module is integrated and typically requires a node takeover or power-down for replacement.
NetApp Reference Documentation:
* Refer to the "NetApp FAS9000 Hardware Service Guide" for supported FRU replacement procedures and operational constraints.
質問 # 45
A node has failed.
Which two conditions must be met for an automatic takeover to be triggered? (Choose two.)
正解：A、C
解説：
For an automatic takeover to occur in an HA pair, the following conditions must be met:
* The HA pair uses mailbox disks to coordinate and ensure that both nodes have consistent cluster state information.
* If the mailbox disks are not reachable, the takeover process cannot proceed.
1. Mailbox Disks Must Be Reachable:
* The nodes in an HA pair continuously mirror NVRAM data to ensure that writes are protected.
* If NVRAM is not synchronized, the takeover cannot safely handle active workloads.
2. NVRAM Must Be Synchronized:
* A. The combined utilization of both nodes must be less than 100%:
* This is not a requirement for automatic takeover. ONTAP can handle higher utilization during failover scenarios.
* B. The cluster network must be available:
* While the cluster network is critical for normal operation, takeover can still occur if the cluster network is unavailable, as long as the HA interconnect is operational.
Why Other Options Are Incorrect:
* NetApp "ONTAP High Availability Guide" outlines the requirements for automatic takeover in HA pairs.
* "ONTAP NVRAM Synchronization and Failover Guide" explains NVRAM mirroring requirements.

質問 # 46
In preparation for an upgrade to ONTAP 9.6P8 software, you have uploaded the ONTAP image
96P8_q_nodar_image.tgz onto your local web server with address 192.168.10.10.
Which is correct command syntax to download this image to the cluster image repository?
正解：D
解説：
Command Syntax for Downloading ONTAP Image:
* The cluster image package get command is used to download the ONTAP image from a specified URL to the cluster's image repository.
* The syntax requires the -url parameter followed by the full URL of the image file.
Why Option C Is Correct:
* This command syntax directly downloads the image from the local web server at http://192.168.10.10/ to the ONTAP cluster repository.
* Other options either refer to incorrect commands or unsupported URLs.
NetApp Reference Documentation:
* The "ONTAP Software Upgrade Guide" provides the exact command and steps for downloading ONTAP images via HTTP or FTP.
質問 # 47
An aggregate has experienced a multiple disk failure due to a failing I/O module (IOM). The module has been replaced and the aggregate is still failed.
What step can be taken to recover the aggregate?
正解：B
解説：
When an aggregate fails due to multiple disk failures caused by a faulty I/O module (IOM), the first step after replacing the faulty IOM is to manually unfail the affected drives. This process is done in maintenance mode.
* Enter Maintenance Mode:
* Reboot the node and interrupt the boot process to access maintenance mode.
* Identify Failed Drives:
* Use the command:
Steps to Recover the Aggregate:sql
Copy code
storage show disk -broken
This command lists all failed (broken) drives.
* Unfail the Drives:
* Use the following command for each failed drive:
php
Copy code
disk unfail <disk-name>
* Reconstruct the Aggregate:
* Once all drives are unfail, the system should begin reconstructing the RAID groups in the aggregate.
* A. Use diskcopy from maintenance mode:
* Diskcopy is used for cloning or copying data between disks, not for recovering failed aggregates.
* B. Run wafliron from the boot_menu:
* wafliron is used to repair WAFL inconsistencies, but it does not help recover failed aggregates due to disk issues.
* D. Unfail the drives in the order that they failed from the clustershell:
* Drives must be unfail in maintenance mode, not from the clustershell.
Why Other Options Are Incorrect:
* NetApp's "Aggregate and RAID Troubleshooting Guide" explains the process of recovering aggregates and using maintenance mode commands.
* "ONTAP Disk Recovery Guide" outlines steps to unfail disks and recover RAID groups.
