Network Appliance NetApp Accredited Hardware Support Engineer Sample Questions (Q45-Q50):

NEW QUESTION # 45
Which statement best describes the functionality of RAID Error Propagation (REP)?

A. An unrecoverable error on a user data block does not trigger a NetApp WAFL inconsistency.
B. An unrecoverable error on a metadata block does not trigger a NetApp WAFL inconsistency.
C. An unrecoverable error on a user data block triggers a NetApp WAFL inconsistency.
D. A recoverable error on a user data block triggers a NetApp WAFL inconsistency.

Answer: A

Explanation:
Functionality of RAID Error Propagation (REP):
* RAID Error Propagation (REP) ensures that errors on the disk layer, such as unrecoverable read errors, do not propagate as inconsistencies into the WAFL (Write Anywhere File Layout) metadata layer.
* WAFL is designed to manage data blocks, and if an error occurs on a user data block, WAFL can identify and handle it gracefully without flagging an inconsistency.
Why Option A Is Correct:
* REP ensures that errors on a user data block are isolated and do not trigger WAFL inconsistencies.
Instead, the error is handled at the RAID layer or higher without corrupting metadata.
* This design provides a robust mechanism to protect against data integrity issues caused by disk errors.
NetApp Reference Documentation:
* Refer to the "ONTAP Storage Management Guide" and the "NetApp RAID Guide," which explain how RAID and WAFL interoperate and how REP is implemented.

NEW QUESTION # 46
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 SVM root volumes are sent back
D. Only the root aggregate is given 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.

NEW QUESTION # 47
Which type of AutoSupport message would you expect to see triggered automatically when ONTAP software detects a NetApp WAFL inconsistency on an aggregate?

A. WAFL INCONSISTENT USER DATA BLOCK
B. MEDIUM ERROR DURING RECONSTRUCTION
C. CHECKSUM ERROR
D. WAFL INCONSISTENT BLOCK

Answer: D

Explanation:
When ONTAP detects a WAFL inconsistency in an aggregate, it automatically generates an AutoSupport message with the description WAFL INCONSISTENT BLOCK.
* WAFL INCONSISTENT BLOCK:
* This error indicates that WAFL metadata or user data blocks have been found to be inconsistent.
* ONTAP triggers an automatic AutoSupport message to notify administrators and NetApp Support.
Key Details:
* A. MEDIUM ERROR DURING RECONSTRUCTION:
* This error occurs during disk reconstruction, not due to WAFL inconsistencies.
* B. CHECKSUM ERROR:
* A checksum error indicates a disk-level data integrity issue, not a WAFL inconsistency.
* C. WAFL INCONSISTENT USER DATA BLOCK:
* While related, this is not the specific AutoSupport message triggered by ONTAP.
Why Other Options Are Incorrect:
* NetApp "ONTAP WAFL Troubleshooting Guide" describes AutoSupport messages related to WAFL inconsistencies.

NEW QUESTION # 48
Which two of the following are field replaceable units (FRUs) on an AFF A220 system? (Choose two.)

A. mSATA boot device
B. chassis fan
C. NVMEM battery
D. NVME Flash Cache feature

Answer: A,C

Explanation:
* A. NVMEM battery
* Explanation:The NVMEM (Non-Volatile Memory) battery is a critical component for retaining data in case of a power failure. It is classified as a Field Replaceable Unit (FRU) in an AFF A220 system.
* Replacement Notes:
* Replacement can be performed by field engineers.
* The system will typically alert you when the battery requires replacement.
* B. mSATA boot device
* Explanation:The mSATA (mini-SATA) boot device contains the ONTAP operating system and is also a FRU in the AFF A220. It is critical for the system's boot process and can be replaced if it becomes faulty.
* Replacement Notes:
* Boot devices are easily replaceable while ensuring ONTAP is reinstalled on the new device.
Why the Other Options Are Incorrect:
* C. NVMe Flash Cache feature:
* Incorrect. NVMe Flash Cache is not a physical FRU but a feature for accelerating read performance. It is implemented via software and NVMe-based SSDs, which are not specifically field replaceable in AFF A220.
* D. Chassis fan:
* Incorrect. The AFF A220 does not classify chassis fans as FRUs. These are usually part of the cooling system, but their replacement may require system shutdown or is integrated into the design.
References:
* NetApp Hardware Documentation: AFF A220 Component Replacement Guide.
* NetApp Knowledge Base: Articles on replacing NVMEM batteries and mSATA boot devices.

NEW QUESTION # 49
Which two statements are correct when describing L1 and L2 Watch Dog Resets (WDR)? (Choose two.)

A. L2 WDR requests creation of a core dump before reset.
B. L1 WDR is initiated after 0.5 seconds from the event.
C. L1 WDR performs a soft reset.
D. L2 WDR is initiated after 2 seconds from the event.

Answer: A,D

Explanation:
* Description:
* L1 WDR is a hardware-initiated reset that occurs when the system detects an unrecoverable error or lockup lasting 0.5 seconds.
* Key Characteristics:
* It performs a hard reset, meaning the system immediately reboots without creating a core dump.
1. L1 Watchdog Reset (WDR):
* Description:
* L2 WDR is initiated when the system fails to recover from a critical fault after 2 seconds.
* Key Characteristics:
* It requests a core dump to capture the system state for diagnostic purposes before performing a reset.
2. L2 Watchdog Reset (WDR):
* B. L1 WDR is initiated after 0.5 seconds from the event:
* This is incorrect because L1 WDR performs a hard reset and does not initiate after 2 seconds.
* C. L1 WDR performs a soft reset:
* This is incorrect because L1 WDR performs a hard reset, not a soft reset.
Why Other Options Are Incorrect:
* "ONTAP Panic Analysis Guide" describes the behavior and timing of L1 and L2 WDR events.
* NetApp Support documentation on system resets explains the differences between L1 and L2 watchdog resets.
