Netapp NS0-077 Exam With Confidence Using Practice Dumps

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.

The SGF6112 is specifically suited to this requirement because StorageGRID supports configuring this appliance to operate as a Gateway Node with caching. NetApp documents the SGF6112 as a compact 1U all-flash appliance containing 12 NVMe SSDs, and explicitly lists its ability to operate as a Gateway Node with caching. This enables frequently accessed S3 objects to be cached close to the application without deploying a complete StorageGRID site containing multiple Storage Nodes.

This architecture is particularly appropriate for a small office with restricted rack space and power. The caching Gateway serves repeatedly accessed objects locally, reducing retrieval latency and WAN traffic while the authoritative object data continues to reside on the existing StorageGRID Storage Nodes.

Options A and C create entirely new StorageGRID sites. A production site requires at least three Storage Nodes, which significantly increases equipment, power, cooling, and rack requirements. C additionally deploys multiple high-performance appliances when only local read acceleration is required.

Option B is invalid because the SG5812 is a Storage Node appliance and does not provide the SGF6112's supported caching-Gateway operating mode.

Therefore, D provides the required local-read performance with the smallest practical physical footprint.

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.
