NEW QUESTION # 37
You have a 4-node NetApp ONTAP cluster that has been using FabricPool technology to tier data to a dedicated StorageGRID endpoint on a grid composed of two Admin Nodes, two Gateway Nodes in an HA group, and four Storage Nodes. After one year, your ONTAP cluster displays an error connecting to the grid to tier data. You have no reports of issues with any other applications or users on your StorageGRID system.
What is the cause of the error?
Answer: B
Explanation:
FabricPool normally connects ONTAP to StorageGRID through an HTTPS load balancer endpoint. That endpoint uses a server certificate so that ONTAP can authenticate the StorageGRID service. NetApp specifically warns that if the certificate securing the ONTAP-to-StorageGRID connection expires, FabricPool temporarily stops working and ONTAP loses access to data tiered to StorageGRID.
The same problem can occur when the endpoint certificate is renewed or replaced in StorageGRID but the corresponding trusted certificate on ONTAP is not updated. NetApp requires the StorageGRID and ONTAP certificate configurations to remain synchronized; after certificate replacement or renewal, ONTAP must trust the new certificate chain.
The scenario also eliminates the node-failure answers. The two Gateway Nodes are configured in an HA group, so failure of one Gateway Node should not independently cause the FabricPool endpoint to become unavailable. Likewise, losing one Storage Node does not normally prevent access to the StorageGRID S3 service. A Client Network trust-state change would have broader networking implications and does not fit the isolated, time-related FabricPool failure described.
Therefore, C is the correct answer.

NEW QUESTION # 38
A StorageGRID site is moving to a new data center with a different network subnet. The environment will remain online with information lifecycle management (ILM) policies that ensure data is replicated across sites.
What is used to configure the network settings for the new data center?
Answer: C
Explanation:
The correct tool for modifying network addressing on an existing StorageGRID deployment is the change-ip tool. NetApp documents that the Change IP tool can modify the network configuration of one or more grid nodes, including the IP address, subnet mask/prefix, gateway, and MTU. It can also update Grid Network configuration and add, modify, or remove Admin and Client Network addressing.
This is the appropriate mechanism when moving an operational StorageGRID site to a new data center where the network subnet changes. The tool provides a controlled workflow to select affected nodes, edit addressing, review the proposed configuration, validate the changes, and then apply them to the grid. StorageGRID 12.0 documentation shows the workflow explicitly through the change-ip command and its menu options for editing IP/mask, gateway, MTU, and Grid Network subnet information.
Option A is primarily used during appliance installation and certain appliance maintenance operations, not as the general grid-wide IP migration tool. Option C bypasses StorageGRID configuration management and must not be used as the normal method for persistent grid-network changes. Option D manages tenant-level S3 resources and cannot modify node networking.

NEW QUESTION # 39
A new application has been installed in your company that requires objects to be converted to another format immediately after they are placed in a specific bucket.
Which two endpoints notify the application? (Choose two.)
Answer: A,B
NEW QUESTION # 40
A primary interface in an HA group has failed, and the virtual IP address (VIP) has moved to a backup interface.
What happens when the primary interface is restored?
Answer: C
Explanation:
StorageGRID HA groups use an explicit interface priority order. The first interface in that order is the Primary interface and normally hosts all virtual IP addresses assigned to the HA group. If the Primary interface becomes unavailable, StorageGRID automatically moves the VIP addresses to the highest-priority backup interface that remains operational.
Importantly, this behavior includes automatic failback. NetApp states that when the failure is resolved and a higher-priority interface becomes available again, the VIP addresses are automatically moved to the highest- priority available interface. Therefore, once the original Primary interface is restored and considered healthy, StorageGRID automatically transfers the VIP back to it. No administrator intervention or Load Balancer service restart is required.
Options A and C are incorrect because restarting the Load Balancer service is not part of the standard HA failback workflow. Option B is also incorrect because StorageGRID does not permanently leave the VIP on a lower-priority backup interface after the preferred interface has recovered. The configured priority order continues to determine which interface should host the HA group's VIPs.

NEW QUESTION # 41
You have a StorageGRID environment consisting of two sites deployed as virtual machines. Site A contains the primary Admin Node, one Gateway Node, and four Storage Nodes. Site B contains a nonprimary Admin Node, one Gateway Node, and four Storage Nodes. All client operations use load balancer endpoints through the Gateway Node. A host in Site A running both the primary Admin Node and Gateway Node has crashed.
What recovery process should you use to resume client operations the quickest?
Answer: A
Explanation:
When a physical or virtual host containing multiple StorageGRID nodes fails, NetApp defines a specific recovery-order requirement when one of those nodes is the primary Admin Node. StorageGRID 12.0 documentation states that if the failed server hosts the primary Admin Node, the primary Admin Node must be recovered first. This prevents subsequent node-recovery operations from stopping while attempting to communicate with services associated with the primary Admin Node.
Therefore, the administrator should deploy a replacement VM for the primary Admin Node and perform the documented primary Admin Node recovery. After the primary Admin Node is operational, recovery of the failed Gateway Node can proceed, restoring the intended client load-balancing path.
Option A is invalid because StorageGRID does not permit adding a primary Admin Node through an expansion; the primary Admin Node is established during initial installation and a failed one must be recovered. Options B and D incorrectly prioritize the Gateway Node while the failed host also contains the primary Admin Node. The StorageGRID 12.0 recovery guidance explicitly requires the primary Admin Node to be handled first in this situation.
