NEW QUESTION # 35
Your customer is running a NetApp AFF A800 system with NetApp ONTAP 9.8 software and states that their NS224 shelf is not showing with the correct shelf ID. You analyze the data and the shelf shows an identification of "1.SHFHUXXXXXXXXXX." What is the cause of the reported Issue?
- A. The shelf has been power cycled.
- B. The shelf had a disk replaced too quickly.
- C. A new shelf was added to the controller.
- D. The shelf was cabled Incorrectly.
Answer: D
Explanation:
According to the NetApp Knowledge Base, adding a second NS224 shelf to an existing stack can cause the first shelf ID to change to the serial number if the cables are not connected properly1. This can also result in a Medium Impact error message: Shelves with both connections via the same SAS path detected2. This situation is not normal for a NetApp AFF A800 system and can affect performance and availability. The cables should be reconnected according to the SAS cabling rules and concepts for shelves with IOM12/IOM12B modules3 and the controller-to-stack cabling worksheet template for quad-pathed connectivity4. Reference = Shelves with both connections via the same SAS path detected, Adding a second NS224 shelf, changes first shelf ID to the serial number, SAS cabling rules and concepts - shelves with IOM12/IOM12B modules, Controller-to-stack cabling worksheet template for quad-pathed connectivity.
NEW QUESTION # 36
Your customer has deployed a two petabyte NetApp ONTAP FlexGroup volume across their 4-node ONIAP 9.8 cluster. They plan to store over three billion files. They want to prevent file 10 conflicts since files are placed into the FlexGroup volume.
In this scenario, which two NFS SVM parameters should be enabled? (Choose two.)
- A. -v4-64bit-idantifiers
- B. -v4-fsid-change
- C. -v3-64bit-identifiers
- D. -v3-fsid-change
Answer: A,C
Explanation:
= To prevent file ID conflicts in a FlexGroup volume, you need to enable 64-bit NFSv3 and NFSv4 identifiers on the SVM that hosts the FlexGroup volume. This allows the SVM to use 64-bit file system IDs (FSIDs) and file IDs, which are unique across the cluster and can accommodate a large number of files. The -v3-64bit-identifiers and -v4-64bit-identifiers parameters enable this feature for NFSv3 and NFSv4 protocols respectively.

NEW QUESTION # 40
A system panic due to an "L2 watchdog timeout hard reset" error occurred. You have found a FIFO message in the SP log.
Which FIFO message Is useful for Investigating this Issue?
- A. before NMI BBSP:C=00 L=00 FIFO: F3 F2 F1 F0 5 B2 0 0 0 80 20 E F E3 C0 C2 3 4 6 7 9 9 A
- B. before Reset BBSP:C=00 L=00 FIFO:
- C. BIOS exit BBSP:C=2F L=20 FIFO: 2 C8 C9 C4 24 4 6 18 7 8 11
- D. ONTAP Shutdown BBSP:C=00 L=2F FIFO:
Answer: A
Explanation:
= The FIFO message before NMI is useful for investigating the issue because it shows the state of the system before the non-maskable interrupt (NMI) was triggered by the L2 watchdog timeout. The FIFO message contains information about the CPU registers, the stack pointer, the instruction pointer, and the last executed instructions. This can help identify the cause of the system hang or deadlock that led to the watchdog reset. The other FIFO messages are not useful because they show the state of the system after the reset or shutdown, which may not reflect the original problem.

NEW QUESTION # 45
A user reports that a colleague saved a file called Test.txt from a UNIX system to a multiprotocol volume. When opening the file later from a Windows system, it was not the file that they wanted. The file that they wanted was named TEST~1.TXT.
Which statement explains this behavior?
- A. Windows Volume Shadow Copy Service stored an older version of the file.
- B. UNIX name mapping updated the filename.
- C. Case Insensitivity of SMB clients caused the file to be displayed with a different name.
- D. A Snapshot copy preserved two versions of the file.
Answer: C
Explanation:
= The multiprotocol volume allows clients to access files using both NFS and SMB protocols. The NFS protocol is case-sensitive, meaning that Test.txt and TEST~1.TXT are two different files. The SMB protocol is case-insensitive, meaning that it treats uppercase and lowercase letters as the same when searching for a file. Therefore, when the user opened the file from a Windows system using SMB, the system could not distinguish between Test.txt and TEST~1.TXT and displayed one of them arbitrarily. This could lead to confusion and data loss if the user modified or deleted the wrong file. Reference = Client protocols; Multiprotocol NAS in NetApp ONTAP Overview and Best Practices, page 30-31.
NEW QUESTION # 46
Your customer mentions that they have accidentally destroyed both root aggregates in their two-node cluster.
In this scenario, what are two actions that must be performed? (Choose two.)
- A. Re-create the cluster from the remote backup.
- B. Re-create the cluster from the local backup.
- C. Rejoin the second node to the re-created cluster.
- D. Install ONTAP from a USB device.
Answer: C,D
Explanation:
If both root aggregates are destroyed in a two-node cluster, the cluster will be inoperable and the data will be inaccessible. To recover from this situation, you need to perform the following actions:
Install ONTAP from a USB device on one of the nodes. This will create a new root aggregate and a new cluster on that node.
Rejoin the second node to the re-created cluster. This will also create a new root aggregate on the second node and synchronize it with the first node.
Restore the cluster configuration and data from a backup, if available. Reference = ONTAP 9 Documentation Center Storage System Recovery Troubleshooting Recovering from a root aggregate failure

NEW QUESTION # 49
Your customer complains that u host will constantly report losing a connection to the iSCSl target and then report that the session was reestablished.
As shown in the exhibit, what is a cause of this flapping?
- A. A host with an IP address of 172.20.10.80 and a second host with an IP address of 10.10.20.60 have the same IQN.
- B. A host with an IP address of 172.20.10.80 and a second host with an IP address of 10.10.20.60 are accessing the same LUN.
- C. A host with an IP address of 172.20.10.80 and a second host with an IP address of 10.10.20.60 are in different initiator groups.
- D. A host with an IP address of 172.20.10.80 and a second IP address of 10.10.20.60 is accessing different LUNs.
Answer: A
Explanation:
IQN stands for iSCSI Qualified Name, which is a unique identifier for an iSCSI initiator or target1.
ONTAP uses IQN to authenticate and authorize iSCSI sessions2.
If two hosts have the same IQN, they will cause a conflict and ONTAP will reject the new session request from the second host3.
This will result in the host losing the connection to the iSCSI target and then reporting that the session was reestablished, as shown in the exhibit.
To avoid this problem, each host should have a unique IQN. Reference:
iSCSI Qualified Name (IQN) - NetApp
iSCSI authentication and authorization - NetApp
