NEW QUESTION # 31
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: B
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 # 32
A customer runs a StorageGRID deployment with six Storage Nodes at a single site. The customer wants to decommission one of the nodes that hosts an Administrative Domain Controller (ADC) service and replace the node with new hardware.
Before proceeding with the decommission, what is done to ensure that grid quorum and metadata operations remain unaffected?
Answer: A
Explanation:
StorageGRID requires an ADC service quorum at each site at all times. The ADC service maintains grid topology information and provides configuration services used throughout the grid. StorageGRID therefore prevents the decommissioning of a Storage Node if removing that node would violate the site's ADC quorum requirements.
StorageGRID 12.0 provides a supported Move ADC procedure specifically for situations where an administrator needs to decommission a Storage Node hosting ADC. The ADC service can be moved to another eligible Storage Node within the same site. The target must not already host ADC and must be either a combined Storage Node or metadata-only Storage Node. NetApp performs the operation through the Grid Management private API, using POST /private/move-adc/start; progress can be monitored with GET /private
/move-adc. The dependent IDNT, ACCT, and RSM services move automatically with ADC.
Option B is invalid because ADC runs on eligible Storage Nodes, not Admin Nodes. Option C is incorrect because StorageGRID 12.0 documents the migration through the Grid Management API rather than a CLI relocation command. Option D is unsupported; administrators do not manually reinstall ADC.
Therefore, A is correct.

NEW QUESTION # 33
What is a purpose of the webhook integration feature in NetApp StorageGRID?
Answer: D
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 # 34
Your customer wants to set up a data pipeline to take advantage of some AWS services on their newly ingested data. The data lives in buckets in the customer's on-premises StorageGRID system.
Which solution replicates the objects to the Amazon S3 buckets for usage?
Answer: A
Explanation:
The correct solution is the CloudMirror service. CloudMirror is a StorageGRID Platform Service that automatically replicates selected objects from a StorageGRID S3 bucket to an external S3-compatible destination, including Amazon S3. NetApp specifically identifies the use case of mirroring newly ingested customer data into Amazon S3 so that AWS services can perform analytics or other processing on that data.
CloudMirror operates independently of the grid's active ILM policies. After object ingest succeeds, StorageGRID attempts to deliver the replicated object to the configured destination as soon as possible. The tenant configures a Platform Services endpoint containing the destination Amazon S3 bucket information and credentials, then applies a CloudMirror replication configuration to the source bucket.
Option B is incorrect because cross-grid replication is designed for replication between StorageGRID systems connected through grid federation, rather than for using Amazon S3 as an external analytics destination.
NetApp XCP and Robocopy are file migration/copy utilities and are not StorageGRID's native event-driven S3 replication mechanism.
Therefore, D. CloudMirror service directly satisfies the requirement to replicate newly ingested StorageGRID objects into Amazon S3 for downstream AWS processing.

NEW QUESTION # 35
A StorageGRID installation is using two sites with multiple SG1100 services appliances for client access.
DNS Round Robin is configured to evenly distribute the traffic to all services appliances.
What increases the throughput for client operations?
Answer: C
Explanation:
Adding another SG1100 services appliance increases aggregate client throughput because each SG1100 can operate as a Gateway Node running the StorageGRID Load Balancer service. With DNS Round Robin, client connections are distributed across the available services appliances, allowing the aggregate load-balancing capacity to scale horizontally. NetApp explicitly identifies increased aggregate throughput and no idle hosts as advantages of the DNS Round Robin load-balancing model.
The SG1100 is specifically designed to provide high-performance Gateway Node and Admin Node services and supports high-speed network connectivity up to 100 GbE. Adding another equivalent SG1100 therefore provides additional processing and network capacity while preserving consistent performance characteristics across the load-balancer pool. NetApp cautions against mixing services appliances with substantially different performance levels when balancing client traffic.
Option B is incorrect because the SGF6112 is a Storage Node appliance, while StorageGRID load-balancer caching is available only on Gateway Nodes. Option C does not provide the same intended horizontal client- throughput expansion. Option D would substitute an SG110, a lower-performance services appliance, and could create inconsistent load-balancing performance.
Therefore, A is the correct answer.
