NEW QUESTION # 54
Which two ONTAP systems support both SSD and SAS disks? (Choose two.)
Answer: A,C
Explanation:
The following ONTAP systems support both SSD and SAS disks:
* Description:
* The FAS2750 is part of NetApp's hybrid storage array product line.
* It supports both SSDs for performance tiers and SAS disks for capacity tiers, making it suitable for mixed workloads.
1. FAS2750
* Description:
* The FAS8200 is an enterprise-level storage system that also supports hybrid configurations with both SSD and SAS drives.
* This system is designed to handle high performance and capacity needs.
2. FAS8200
* A. AFF C190:
* The AFF C190 is an all-flash system and only supports SSDs. It does not support SAS disks.
* C. AFF A220:
* Like the AFF C190, the AFF A220 is also an all-flash system that supports SSDs only.
Why Other Options Are Incorrect:
* NetApp "Hardware Universe" confirms drive support for FAS and AFF systems.
* NetApp product documentation details supported disk types for hybrid and all-flash systems.

Which two NetApp tools should be used when troubleshooting the root cause of an unexpected controller reboot? (Choose two.)
Answer: B,E
Explanation:
To troubleshoot the root cause of an unexpected controller reboot, the following tools are commonly used:
* What it does:Provides monitoring and performance data for the ONTAP cluster, including historical event logs that may help identify the root cause of a reboot.
1. Active IQ Unified Manager
* What it does:The CLI allows you to gather logs and status information directly from the affected node.
Commands like event log show and system core are essential for identifying the reason behind the reboot.
2. ONTAP CLI
* B. Active IQ Digital Advisor:
* This tool focuses on predictive analytics and proactive recommendations, not troubleshooting unexpected reboots.
* D. ONTAP Mediator:
* This tool is used for managing MetroCluster configurations, not for troubleshooting reboots.
* E. Active IQ Config Advisor:
* This tool checks for configuration best practices but does not provide detailed logs or reboot diagnostics.
Why Other Options Are Incorrect:
* NetApp "ONTAP System Management Guide" emphasizes the use of Unified Manager and CLI for troubleshooting system issues.

NEW QUESTION # 56
During an ONTAP upgrade, nodeA1 fails to boot. You notice that it is loading the previous version of ONTAP software. What step can be taken to boot the node successfully?
Answer: D
Explanation:
When a node fails to boot and loads the previous version of ONTAP, it usually indicates that the primary boot location is incorrect. To resolve this:
* Enter the LOADER Prompt:
* Interrupt the boot process to access the LOADER prompt.
* Set the Primary Kernel URL:
* Use the following command:
Steps to Boot the Correct ONTAP Version:setenv GX_PRIMARY_KERNEL_URL
<URL_to_correct_ONTAP_version>
* Boot the Node:
* Run the boot command to load the correct version.
* B. From the loader prompt of nodeA1, run boot_backup:
* Booting the backup image may result in an outdated version of ONTAP, not the desired version.
* C. From the clustershell of the partner, run system node image modify:
* Modifications to the ONTAP image must be done from the LOADER prompt, not the clustershell.
* D. From the clustershell of nodeA1, run system node image modify:
* NodeA1 cannot load ONTAP, so this command cannot be run.
Why Other Options Are Incorrect:
* "ONTAP System Boot Guide" explains how to resolve boot issues using the LOADER prompt.
* NetApp documentation on environment variables includes the use of GX_PRIMARY_KERNEL_URL.

NEW QUESTION # 57
Which type of core file is generated when a node panics?
Answer: B
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 # 58
A SAS connection is reporting a single PHY down.
What are the two most likely causes? (Choose two.)
Answer: A,B
Explanation:
Understanding a Single PHY Down Issue:
* In SAS environments, a PHY represents a physical layer connection between devices.
* When a single PHY reports a "down" status, it typically indicates an issue with the physical connectivity or the associated hardware.
Cause 1: Improperly Seated Cable
* If the SAS cable is not properly seated in the port, the connection for one or more PHYs may fail.
* Reseating the cable on both ends (controller and shelf) often resolves the issue.
Cause 2: Defective Cable
* A damaged or faulty SAS cable can cause PHY errors.
* Replacing the cable and verifying the connection resolves the issue in this case.
Why Other Options Are Not Likely:
* B. Outdated IOM firmware: While outdated firmware can cause other issues, it rarely affects only a single PHY.
* D. Offline shelf: If an entire shelf is offline, more than one PHY would typically be affected, as multiple connections are involved in SAS stacks.
NetApp Reference Documentation:
* Found in the "ONTAP SAS Cabling Guide" and "Shelf Troubleshooting Guide". These documents detail troubleshooting for PHY errors and common SAS hardware issues.
