Network Appliance NetApp StorageGRID Administrator Exam Sample Questions (Q61-Q66):

NEW QUESTION # 61
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 # 62
A customer has an AI/ML training workload that accesses the same objects multiple times. They have a requirement to enable caching to increase performance.
What StorageGRID node type supports this feature?

Answer: C

Explanation:
The correct answer is Gateway Node. StorageGRID 12.0 provides load balancer caching, which is specifically designed to improve performance when workloads repeatedly access the same subset of objects. NetApp identifies AI/ML training as a strong candidate for this feature because training jobs often reread the same datasets across multiple epochs. By serving frequently requested objects from cache, StorageGRID can reduce backend object retrieval activity and lower response latency.
NetApp explicitly states that load balancer caching is available only on Gateway Nodes. Administrators enable caching on a load balancer endpoint associated with Gateway Nodes and should use dedicated cache- enabled endpoints for workloads that benefit from repeated reads. NetApp also lists data lakes, high- performance computing, AI/ML training, content distribution, media asset management, and video production as examples of workloads that can benefit from caching.
Option B is incorrect because Storage Nodes hold object data and metadata but do not provide the integrated load-balancer caching capability. Option C is incorrect even though Admin Nodes run the Load Balancer service; the caching feature itself is restricted to Gateway Nodes. Archive Nodes are unrelated to this functionality.
Therefore, D. Gateway is the verified answer.
Reference topics: StorageGRID 12.0 # Gateway Nodes # Load Balancer Caching # Cache-Enabled Endpoints # AI/ML Training Workloads


NEW QUESTION # 63
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.
Reference topics: Software Update # Rolling Upgrade # Hotfix Installation # Node Availability # HA Client Connectivity # ILM Redundancy


NEW QUESTION # 64
What is a purpose of the webhook integration feature in NetApp StorageGRID?

Answer: A

Explanation:
StorageGRID supports webhook endpoints as destinations for S3 bucket event notifications. The purpose is to allow external applications, automation systems, or data-processing workflows to react when configured S3 events occur, such as object creation or deletion. NetApp documents that a tenant can configure an external or locally hosted webhook endpoint that accepts HTTP POST notification requests. Platform-service messages are generated from StorageGRID and delivered to the configured endpoint, enabling event-driven application integration.
This makes B the correct answer. For example, after an object is uploaded to a bucket, StorageGRID can generate a notification that is delivered to a webhook. The receiving application can then start processing, indexing, transformation, compliance validation, or another automated workflow without continuously polling the bucket.
Option A describes Cloud Storage Pools/ILM-based external storage placement, not webhook integration.
Option C describes ONTAP SnapMirror orchestration, which is not the function of StorageGRID webhook notifications. Option D is also incorrect: webhook-based S3 event notifications are a tenant platform service, not a replacement for Grid-level alerting technologies such as SNMP, email notifications, and StorageGRID monitoring.
NetApp identifies platform services as including CloudMirror replication, bucket event notifications, and search integration, with webhook endpoints supported specifically for event-notification delivery.
Reference topics: Tenant Manager # Platform Services # S3 Event Notifications # Webhook Endpoints # HTTP/HTTPS POST # Event-Driven Integration


NEW QUESTION # 65
A customer wants to test their application against a StorageGRID system to verify its compatibility.
What is the minimum number and type of nodes required to deploy a healthy virtual StorageGRID environment for this test?

Answer: A

Explanation:
A healthy StorageGRID deployment requires one primary Admin Node and at least three Storage Nodes at each site. NetApp StorageGRID 12.0 documentation states that every grid requires a primary Admin Node to provide core management and configuration services, while every site requires a minimum of three Storage Nodes. Therefore, the smallest healthy single-site virtual test environment contains four nodes: one Admin Node plus three Storage Nodes.
The three-Storage-Node minimum is important because Storage Nodes host core distributed services such as Cassandra, DDS, and ADC. In particular, the ADC service is hosted on at least three Storage Nodes at a site, supporting grid topology information, authentication, and service discovery.
Option A lacks the required primary Admin Node and therefore cannot constitute a complete manageable StorageGRID grid. Option D contains an Admin Node but only one Storage Node, which does not satisfy the three-node minimum. Option C would work, but the Gateway Node is optional because Admin Nodes can also provide S3 load-balancing functionality for a small compatibility-test deployment.
Therefore, B is the minimum healthy virtual configuration.
