質問 # 94
A node has unexpectedly failed and is unresponsive through its node management interface.
Which two commands from the Service Processor are helpful to determine the root cause?
(Choose two.)
正解：B、D
解説：
To determine the root cause of an unexpected node failure using the Service Processor (SP), the following commands are helpful:
1. event log show
What it does:
Displays recent events logged by the Service Processor. This includes hardware failures, environmental alerts, or other events that may have caused the node failure.
2. system core
What it does:
Shows information about any core dumps that were generated during the failure. A core dump provides a snapshot of the system state at the time of the failure, which can be analyzed to identify the root cause.
質問 # 95
What are the two steps to unfail a disk in maintenance mode? (Choose two.)
正解：B、D
解説：
Steps to Unfail a Disk in Maintenance Mode:
When a disk is marked as "failed," it is added to the Failed Disk Registry and marked as unusable by the system. Unfailing a disk involves removing it from this registry and resetting its state.
Step 1: Remove the Disk from the Failed Disk Registry
Use the command: registry remove <disk> to delete the disk from the Failed Disk Registry. This clears its "failed" status.
Step 2: Use the Disk Unfail Command
Execute the disk unfail <disk> command to reset the disk status and make it available for use.
Key Notes:
After unfailing, the disk will be treated as a spare and must be reassigned or re-added to an aggregate.
If the disk remains failed after these steps, physical hardware issues may need to be addressed.
質問 # 96
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?
正解：D
解説：
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.
質問 # 97
You have replaced a failed boot device. You perform boot_recovery and receive no errors.
However, when the node reboots, it reports that it has no disks. What are two possible causes?
(Choose two.)
正解：A、B
解説：
Possible Causes for "No Disks" Error:
A (Incorrect SAS Cabling): If the SAS cables are incorrectly reconnected or swapped after replacing the boot device, the disks may not be detected because the physical connection to the shelves is compromised. Verifying and reseating the SAS cables is essential.
C (Lower ONTAP Version): If the node boots into an ONTAP version that is lower than the version previously used, it might not recognize the RAID labels or disk metadata created by the higher ONTAP version.
質問 # 98
In a SAS stack of shelves, what is the topology of the connection between expander and disk?
正解：C
解説：
In a SAS stack of shelves, the connection between the expander and the disk uses a point-to- point topology.
Key Details:
Point-to-Point:
Each SAS disk in a shelf connects directly to the expander using a dedicated channel. This ensures that communication between the disk and expander is independent of other disks, improving performance and reliability.
Why SAS Uses Point-to-Point:
SAS (Serial Attached SCSI) eliminates the shared bandwidth limitations of traditional bus architectures (e.g., arbitrated loop or ring) by dedicating a connection to each device.
