NEW QUESTION # 38
During performance troubleshooting, you notice that the disk device sdc on Storage Node 3 is handling significantly more I/O operations than the other disks.
What is the reason for this behavior?
Answer: C
Explanation:
The increased I/O on sdc is expected when that device corresponds to storage volume 0 (/var/local/rangedb/0), because StorageGRID uses volume 0 for the Cassandra database that stores object metadata. NetApp documents that StorageGRID maintains object metadata independently from object data in Cassandra and reserves space specifically on volume 0 of every Storage Node for metadata storage and essential database operations.
Cassandra performs continuous metadata-related activity, including database reads and writes, compaction, indexing, consistency operations, and repair. Consequently, the disk containing volume 0 can exhibit noticeably higher I/O than the remaining object-storage volumes even when object data itself is reasonably balanced. NetApp diagnostic examples also show sdc associated with /var/local/rangedb/0, illustrating the relationship between this device and the StorageGRID metadata volume.
Option A does not explain persistent device-specific activity because object ingest is handled through StorageGRID services and ILM placement. Option B would indicate an object-placement issue rather than systematically higher I/O on volume 0. Option D is also incorrect because higher utilization is not necessarily caused by a larger number of stored object payloads.

NEW QUESTION # 39
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: C
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 # 40
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: C
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 # 41
During a troubleshooting session with a NetApp Support Engineer, you are asked to upload log files for further analysis.
Which two methods do you use to generate and upload the required logs to NetApp Support using upload.
netapp.com/sg? (Choose two.)
Answer: B,D
Explanation:
StorageGRID diagnostic information requested by NetApp Support can be collected through the Grid Manager log-collection interface . NetApp documents SUPPORT > Tools > Log collection as the standard StorageGRID mechanism for gathering logs, configuration data, system information, and other diagnostic content from selected grid nodes. The resulting .tar.gz archive can be downloaded or sent to NetApp Technical Support.
NetApp Active IQ OneCollect is also a NetApp diagnostic collection framework that supports StorageGRID environments and can collect consolidated support information for troubleshooting. NetApp documentation identifies OneCollect as a mechanism for gathering diagnostic data from supported NetApp systems, including StorageGRID, and making that information available for support analysis.
Lumberjack is a StorageGRID node-level troubleshooting utility and remains useful for specialized log collection, but for this question's wording-specifically generating and uploading support data through the NetApp support workflow-the intended choices are OneCollect and Grid Manager log collection .
NEW QUESTION # 42
A StorageGRID ILM policy has moved objects belonging to a specific bucket to a Cloud Storage Pool. The objects have transitioned automatically to S3 Glacier Deep Archive storage class to minimize costs. A user now requires immediate access to one of these archived objects.
How can the user achieve this goal?
Answer: C
Explanation:
When an object stored in a Cloud Storage Pool has transitioned to Amazon S3 Glacier Deep Archive, it is in a non-retrievable state. StorageGRID therefore cannot satisfy a normal GetObject request until a retrievable copy has first been restored. NetApp specifies that the client application must issue an S3 RestoreObject request to restore the object temporarily within the Cloud Storage Pool. After the restoration completes, the client can issue GetObject through StorageGRID to retrieve the data.
For a restored object, RestoreObject specifies how long the retrievable copy remains available. StorageGRID supports restoration from Glacier Deep Archive, but Deep Archive does not support the Expedited retrieval tier; only Standard or Bulk retrieval can be used. Thus, "immediate" access means initiating the restore process immediately, not instantaneous retrieval from the Deep Archive tier.
Option A is incorrect because GetObject does not automatically restore a non-retrievable Glacier object.
Option B is incorrect because restoration is performed through StorageGRID's S3 API; direct Amazon- console intervention is unnecessary. Option C is incorrect because StorageGRID explicitly supports RestoreObject for Cloud Storage Pool objects transitioned to Glacier Deep Archive.
