NEW QUESTION # 60
An enterprise is expanding a single-site StorageGRID deployment and is adding new nodes on a new subnet.
What is a requirement for configuring the Grid Network?
Answer: A
Explanation:
When an existing StorageGRID deployment is expanded with nodes whose Grid Network IP addresses are on a subnet that has not previously been used, that subnet must be added to the Grid Network subnet list before the expansion is started. StorageGRID maintains this list so that every grid node can correctly route internal Grid Network traffic to the other participating subnets. NetApp StorageGRID 12.0 documentation explicitly states that if any new node uses a new Grid Network subnet, the administrator must add that subnet first; otherwise, the expansion must be cancelled, the subnet added, and the expansion restarted.
The configuration is performed in Grid Manager # Maintenance # Network # Grid Network, where the administrator selects Add another subnet and enters the network in CIDR notation. StorageGRID then distributes the routing configuration throughout the grid.
Option A is incorrect because routes do not need to be configured manually on every node. Option B is incorrect because a StorageGRID Gateway Node provides client load-balancing functions and is not an IP router between Grid Network subnets. Option D is also incorrect; StorageGRID explicitly supports multiple Grid Network subnets, provided they are routable through the configured Grid Network gateway.

NEW QUESTION # 61
A user is having an issue deleting a version of an object in a bucket that they are working with.
What must the user check to see if they have the correct permissions?
Answer: D
Explanation:
To delete a specific version of an S3 object, the user must have the appropriate S3 permission, specifically s3:
DeleteObjectVersion. In StorageGRID, permissions granted to tenant users are commonly defined through group policies, which control which S3 actions members of the group are authorized to perform against specified bucket and object resources. NetApp explicitly maps s3:DeleteObjectVersion to the S3 operation that deletes a specific object version.
Therefore, the user should verify the group policy associated with their tenant account and confirm that it allows s3:DeleteObjectVersion for the required bucket or object ARN. An explicit Deny for this action would override an Allow. NetApp even provides policy examples that specifically restrict users from deleting versioned objects by denying s3:DeleteObjectVersion.
Option B is incorrect because an S3 lifecycle policy automates object expiration and version-management behavior; it does not grant interactive user permissions. Option C governs where and how StorageGRID stores and protects object data, not S3 authorization. Option D refers to administrative privileges and is not the standard mechanism controlling a tenant user's object-level S3 operations.
Therefore, A. group policy is correct.

NEW QUESTION # 62
Your team is troubleshooting intermittent connectivity issues during peak hours. You suspect that one or more StorageGRID nodes might be experiencing performance issues or downtime, and you want the load balancer to automatically skip these nodes.
Which feature in the third-party load balancer is designed to detect unresponsive nodes and prevent them from receiving client requests?
Answer: C
Explanation:
The correct feature is health checks. When a third-party load balancer is placed in front of StorageGRID nodes, it must continuously determine which backend nodes are healthy enough to accept S3 client traffic.
NetApp specifically recommends configuring a health-check mechanism so the load balancer can test each node and remove an unhealthy or unresponsive node from the active pool.
For StorageGRID, NetApp recommends using an HTTP OPTIONS request as a health probe. The load balancer sends the request directly to each Storage Node and expects an HTTP 200 response. If a node repeatedly fails to return the expected response, the third-party load balancer marks that node offline and stops directing new client connections to it. NetApp's guidance gives an example polling interval of once per second and marking a node offline after three failed checks.
Option A, GSLB, distributes traffic between geographically separate sites or data centers rather than determining the health of an individual backend node. Option C, SSL offloading, handles TLS processing.
Option D, session persistence, keeps a client's requests associated with a selected backend and does not detect failed nodes.
Therefore, B. health checks directly satisfies the requirement.

NEW QUESTION # 63
A StorageGRID system is composed of Linux-based nodes running on hosts in your data center. You want to decommission Host-A containing Storage Node Linux-Node-1, and you must migrate Linux-Node-1 to a new host, Host-B.
What is the correct sequence of steps to migrate Linux-Node-1 from Host-A to Host-B?
Answer: B
Explanation:
NetApp defines a specific workflow for migrating a Linux-based StorageGRID node between hosts. The source node must first be shut down cleanly using storagegrid node stop. After the node has stopped, the administrator runs storagegrid node export on the source host. The export output identifies the /var/local storage volume and provides the corresponding import command to use on the target host.
On Host-B, the administrator runs storagegrid node import against the exported node storage. NetApp then requires the imported configuration to be checked with storagegrid node validate. After successful validation, the migrated node is started with storagegrid node start, and Grid Manager is used to confirm that the node returns to a green operational state with no alerts.
Therefore, C represents the required migration sequence. Although the option summarizes the final validation
/start phase, its stop # export # import # verify ordering matches NetApp's prescribed procedure.
Option A is incorrect because Grid Manager does not automatically migrate Linux containers. Option B reverses the export/import sequence. Option D incorrectly treats migration as a new StorageGRID installation and node reconfiguration.

NEW QUESTION # 64
Your customer is a service provider that wants to host static images for multiple customer websites in different domains, but from a single DNS endpoint. All traffic must be HTTPS encrypted to ensure security and validity of content.
What do you configure to prevent error messages?
Answer: A
Explanation:
The correct configuration is Cross-Origin Resource Sharing (CORS). StorageGRID supports CORS specifically so that objects stored in an S3 bucket can be accessed by web applications originating from different domains. NetApp's documentation uses essentially this exact use case: an S3 bucket containing images can be configured with CORS so that those images can be displayed by a website hosted in another domain.
For a service provider hosting image objects centrally while multiple customer websites access those objects from separate domains, the browser treats the requests as cross-origin. A CORS configuration on the S3 bucket defines the permitted origins, HTTP methods such as GET, and allowed headers. The administrator can either authorize specific customer domains or, where appropriate, permit GET requests from multiple origins. HTTPS remains handled independently by the StorageGRID load balancer endpoint and its TLS certificate.
Option C is incorrect because the HTTPS certificate must match the StorageGRID endpoint domain names clients connect to, not every external website that merely references the images. Option A is unnecessary because one endpoint can service multiple domains, and Swift is unrelated.
