The degraded health output identifies Node-02 port e0a with link_flapping, indicating an unstable physical connection on that node port. Replacing the SFP on the affected port is the appropriate corrective action.
NEW QUESTION # 28
A storage administrator is troubleshooting a 4-node cluster, where one node is reporting "cluster port is down" alerts. The node has recently been recabled to new cluster switches. The cluster ping-cluster command shows communication failures between the affected node and its partners over the cluster network. All physical cables have been verified as properly seated and undamaged. Which configuration is causing this problem?
- A. An incorrect gateway is defined for the management network.
- B. An incorrect intercluster LIF is configured.
- C. The SVM data LIFs are on the wrong ports.
- D. The MTU size on the new cluster switches is mismatched with the nodes.
Answer: D
Explanation:
Cluster ports require consistent MTU settings between the ONTAP nodes and the cluster switches. After recabling to new cluster switches, an MTU mismatch can cause cluster network communication failures even when the physical cabling is correct.
NEW QUESTION # 29
Your customer notices that their AFF A220 high-availability (HA) system is showing Single-Path HA.
How do you make the system into multipath HA?
- A. 0c and 0d on both controllers should be connected.
- B. 0a and 0b on both controllers should be connected.
- C. 0a and 0d on both controllers should be connected
- D. 0a and 0c on both controllers should be connected.
Answer: D
Explanation:
In a NetApp high-availability (HA) configuration, multipath HA ensures redundancy by providing two independent paths from each controller to the connected storage. If the system is currently showing Single-Path HA, it means only one path is operational or connected, which is a potential single point of failure.
To convert the configuration to multipath HA, additional cabling must be configured to establish the second path. For the AFF A220 system, the correct connections are as follows:
Explanation of the Correct answer:
AFF A220 Port Configuration for HA:
Each controller in an AFF A220 has ports labeled 0a, 0b, 0c, and 0d for connectivity.
In a multipath HA configuration, each controller must have two independent paths to the connected storage via the partner controller's disk shelves.
Correct Cabling for Multipath HA:
Port 0a on both controllers must be connected to the corresponding port (e.g., disk shelf stack or Inter-Switch Link).
Port 0c on both controllers must also be connected to complete the redundant path.
These connections ensure that there are two independent data paths between the controllers and the storage system, providing fault tolerance in case one path fails.
Single-Path HA to Multipath HA:
If the system currently shows Single-Path HA, it is likely that only one set of ports (e.g., 0a and
0b) are cabled.
Adding the additional connections on 0a and 0c establishes the second path required for multipath HA.
NEW QUESTION # 30
A 4-node NetApp ONTAP cluster sent an alert that one of the cluster interconnect switches has failed.

Which parameter must the system administrator enable to automatically migrate the cluster LIFs?
- A. allow-lb-migrate
- B. auto-revert
- C. failover-policy
- D. home-port
Answer: B
Explanation:
Enabling auto-revert allows cluster LIFs to automatically migrate back to their designated home ports after the failed cluster switch has been replaced and connectivity is restored.

- C. system node autosupport invoke -node * -type all -message IGNORE=5h
- D. system node autosupport invoke -node * -type all -message MAINT=5h
Answer: D
Explanation:
The system node autosupport invoke -message MAINT=5h command places the system into a maintenance window for five hours, preventing automatic support case creation during planned activities such as switch firmware upgrades.
NEW QUESTION # 32
You have upgraded your cluster from ONTAP 9.5 software to ONTAP 9.7 software. After two days, you notice that the upgrade is causing issues. You decide to revert to ONTAP 9.5 software.
Which two actions do you need to complete before you revert? (Choose two.)
- A. Delete all Snapshot copies from the past two days.
- B. Wipe your config and restore from backup.
- C. Reinstall your boot media and install ONTAP 9.5 software.
- D. Revert from ONTAP 9.7 software to ONTAP 9.6 software and then to ONTAP 9.5 software.
Answer: B,C
Explanation:
Reverting to a previous ONTAP version requires careful preparation because ONTAP upgrades often introduce irreversible changes. To successfully revert, the following actions are needed:
C). Reinstall your boot media and install ONTAP 9.5 software
You need to reinstall the older version of ONTAP (9.5) on the boot media because the current version (9.7) has been installed as part of the upgrade. The reinstallation ensures that the system boots with ONTAP 9.5.
Steps:
Boot the node into maintenance mode.
Perform the reinstallation using the appropriate ONTAP 9.5 image.
D). Wipe your config and restore from backup
A revert requires wiping the configuration because ONTAP upgrades may have made changes to the cluster configuration or WAFL metadata. Restoring the configuration from a backup ensures consistency with the older ONTAP version.
Steps:
Back up the current cluster configuration before proceeding.
Use the restored backup after the revert is complete to reconfigure the system.

After a panic, the customer asks you to explain the error "watchdog timeout." Which explanation would be appropriate?
- A. An optional component included with Active IQ Unified Manager.
It notifies a user if watchdog fails to reach the storage system within a certain period. - B. An optional software that monitors system performance.
An overloaded system fails to reset the watchdog and watchdog induces a system panic. - C. A service that monitors network activity and protects data.
A watchdog induces system panic to protect data if malicious activity is detected. - D. A service that detects and recovers from computer malfunctions.
A hardware or software error prevents update of watchdog and it induces a system panic.
Answer: D
Explanation:
What Is a Watchdog Timeout?
The watchdog is a software or hardware mechanism that monitors the system's health and ensures it is operating correctly.
If the system fails to respond or update the watchdog timer within the specified time, the watchdog triggers a system panic to avoid further corruption or damage.
Cause of Watchdog Timeout:
This usually occurs due to:
A hardware failure (e.g., CPU or memory issue).
A software bug causing a system hang or crash.
The panic ensures the system stops operation to preserve data integrity and aid in troubleshooting.
