NEW QUESTION # 13
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: C
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 # 14
Which statement about controlling access with group policies is true?
Answer: B
Explanation:
In StorageGRID, group policies are attached to a specific tenant group and define which S3 resources members of that group are permitted or denied access to. NetApp explicitly states that a group policy applies to only one group and can apply to multiple buckets. This makes B the correct answer.
Group policies are configured through Tenant Manager or the Tenant Management API and use AWS- compatible JSON policy syntax. A single group policy can therefore contain multiple Resource entries referencing different buckets and objects. In contrast, a bucket policy is attached to one specific bucket and can grant or deny access to multiple users or groups.
Options A and C are incorrect because StorageGRID does not assign precedence among group, bucket, and session policies. NetApp states that there is no difference in priority among these policy types. Authorization is determined by evaluating the applicable policy statements, with an explicit Deny overriding an Allow; it is not based on one policy class automatically taking precedence over another.
Option D reverses the relationship: it describes the scope of a bucket policy rather than a group policy.

NEW QUESTION # 15
You intend to perform maintenance on a customer's VMware ESXi, which hosts a StorageGRID Storage Node as a virtual machine (VM).
Which procedure maintains the integrity of the grid?
Answer: D
Explanation:
For a StorageGRID node running as a VMware virtual machine, NetApp requires the node to be gracefully shut down before hypervisor migration or maintenance. The supported migration approach is therefore a cold migration, in which the StorageGRID node is stopped before it is moved to another ESXi host. NetApp documentation explicitly states that cold migration is supported.
Option A is specifically unsupported. NetApp warns that VMware live vMotion can cause the virtual machine clock to jump. StorageGRID depends heavily on synchronized time for distributed database operations, object metadata, configuration updates, and inter-node coordination. A time discontinuity can therefore lead to data or configuration integrity problems, which is why live vMotion must not be used for StorageGRID grid nodes.
Option B is incorrect because StorageGRID appliance maintenance mode is intended for specific appliance maintenance procedures; it is not the prescribed migration workflow for a VMware-hosted software Storage Node. Option C is also not the required host-maintenance procedure and unnecessarily introduces datastore- level movement considerations.
Thus, the correct sequence is to gracefully shut down the StorageGRID VM and perform a cold migration to another ESXi host, preserving grid integrity while host maintenance is performed.

NEW QUESTION # 16
Your customer wants to maintain high availability during maintenance activities such as upgrades, hotfixes, and firmware updates.
Which best practice should the customer follow to ensure minimal disruption?
Answer: C
Explanation:
StorageGRID maintenance should be performed using a rolling, node-by-node approach so that the grid continues providing S3 services while individual nodes are temporarily unavailable. NetApp states that StorageGRID upgrades are designed to be non-disruptive: nodes of the same type are taken down and upgraded one at a time, preventing all nodes of a particular role from becoming unavailable simultaneously.
NetApp also permits administrators to approve individual nodes or groups of nodes and, when upgrade order is important, explicitly recommends waiting for one node or group to complete before approving the next.
During this process, administrators should monitor Grid Manager for node status, alerts, and service health.
High availability also depends on appropriate architecture: ILM policies should maintain redundant object copies, and S3 clients should connect through HA-group VIPs, highly available third-party load balancers, or multiple Gateway Nodes.
Option A increases operational risk by scheduling maintenance during peak load. Option C could remove too much grid capacity simultaneously and defeat redundancy. Option D is not a prescribed StorageGRID maintenance procedure and could unnecessarily disrupt grid and client communication.

NEW QUESTION # 17
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: C
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.
