NEW QUESTION # 16
A company is scaling its StorageGRID environment to support a massive increase in object count, aiming for trillions of objects over the next few years. They need an appliance model that can handle this significant increase in scale and performance demands.
Which NetApp StorageGRID appliance model takes advantage of the increased scaling limits?
Answer: C
Explanation:
The SG6160 is the best match for environments designed for very large-scale StorageGRID deployments.
StorageGRID 12.0 substantially increases overall platform scalability, supporting up to one trillion objects, more than twice the previous platform limit. This increase is enabled in part by a newer Cassandra version that stores object metadata more efficiently, allowing considerably larger object populations to be maintained.
The SG6160 is NetApp's higher-scale disk-based StorageGRID appliance. Its SG6100-CN compute controller provides 48 CPU cores and 256 GB of RAM, providing substantially more compute and memory resources for StorageGRID services than capacity-oriented SG5800 models. It also supports a 60-drive base shelf plus as many as two 60-drive expansion shelves, for a maximum of 180 drives per appliance. NetApp specifically positions the SG6160 and its expansion configuration for large-scale deployments, transactional small-object workloads, and data lakes.
The SG5812 and SG5860 are positioned primarily as cost-optimized secondary-storage platforms. The SG1100 is a services appliance used for Admin Node and Gateway Node functions and does not provide object-storage capacity.
Therefore, D. SG6160 is the appropriate selection for this scale-oriented requirement.

NEW QUESTION # 17
After upgrading to StorageGRID 12.0, your organization wants to retain audit logs for long-term compliance.
How can you back up audit logs automatically?
Answer: B
Explanation:
StorageGRID 12.0 introduces an integrated mechanism for long-term log archival to an S3 system bucket.
NetApp specifically identifies this as a StorageGRID 12.0 manageability enhancement: the former Audit and syslog server page was renamed Log management, with functionality added for storing logs in a system bucket for backup purposes.
From Grid Manager, the administrator uses Log management # Log location # Use a bucket and enables archive logs. A tenant and S3 bucket can then be created or selected. StorageGRID automatically stores rotated log files in that bucket, using object keys beginning with system-logs/. This eliminates the need for node-level scripts or periodic manual copying.
Option A is incorrect because StorageGRID already performs native log rotation; custom rotation scripts do not provide the StorageGRID 12.0 archival mechanism. Option B refers to legacy audit-export behavior rather than the new long-term backup capability. Option C is technically possible as a manual administrative operation but does not satisfy the requirement for automatic backup.
For compliance retention, administrators can additionally control archived-log lifetime through an ILM rule or S3 bucket lifecycle policy.

NEW QUESTION # 18
To comply with an industry regulation, a bank is establishing a disaster recovery solution across two grids.
The tenant federation was successfully configured. You are required to unidirectionally replicate a critical bucket from Grid-1 to Grid-2 and ensure that all of the content is identical on each grid, to reestablish operations in the event that Grid-1 fails.
After creating a bucket with versioning enabled on each grid, what are the required steps to complete the task?
Answer: B
Explanation:
For unidirectional cross-grid replication, CGR must be enabled on the bucket in the grid that acts as the source. NetApp states that when CGR is enabled on only one grid, objects added to that source bucket are replicated automatically to the corresponding destination bucket on the other grid; objects written to the destination are not replicated back. Because the required direction is Grid-1 # Grid-2, CGR must therefore be enabled on Grid-1.
The administrator then selects the appropriate grid federation connection and sets Replicate delete markers = Yes. When an S3 client deletes an object without specifying a version ID, StorageGRID creates a delete marker. With this option enabled, that marker is replicated to Grid-2 so the object appears deleted on both grids, helping maintain matching bucket state. NetApp documents this as the default behavior.
Option A would configure bidirectional replication, which violates the unidirectional requirement. Option B reverses the required replication direction. Option D is incorrect because the relevant CGR configuration control is Replicate delete markers, not "Replicate metadata."

NEW QUESTION # 19
Which StorageGRID feature enables you to have multiple active information lifecycle management (ILM) policies?
Answer: D
Explanation:
The feature that enables multiple active ILM policies is ILM policy tags. NetApp StorageGRID allows administrators to create multiple ILM policies and associate each policy with a specific policy tag. Tenants can then assign one of those ILM policy tags to an S3 bucket, causing objects in that bucket to be managed by the ILM policy associated with the selected tag. This enables different buckets to receive different data- protection, placement, retention, or performance treatments while those policies remain active simultaneously.
StorageGRID also maintains a Default ILM policy tag. Every grid must have an active policy associated with the Default tag, and that policy governs objects in buckets that do not have another ILM policy tag assigned.
NetApp supports up to 10 policy tags per grid.
Option A is too general. Although StorageGRID implements the assignment on an S3 bucket, the enabling construct is specifically the ILM policy tag. Option C, multitenancy, separates tenant resources but does not itself permit multiple active ILM policies. Option D, IAM policy, controls S3 access permissions and authorization rather than ILM placement or retention behavior.
Therefore, B is the correct answer.

NEW QUESTION # 20
A StorageGRID site has virtual and physical Storage Nodes of several different sizes.
The metadata capacity is sized based on which node?
Answer: C
Explanation:
StorageGRID distributes object metadata evenly across the Storage Nodes participating in metadata storage at a site. Consequently, when Storage Nodes have different metadata capacities, the smallest Storage Node becomes the limiting factor for the site's usable metadata capacity. NetApp explicitly states that when a site contains Storage Nodes of different sizes, the smallest node at that site determines the site's metadata capacity.
The underlying consideration is particularly tied to volume 0, because StorageGRID stores Cassandra object metadata on volume 0. NetApp recommends configuring comparable volume 0 sizes across Storage Nodes whenever possible. If different sizes are used, the node with the smallest volume 0 establishes the effective per-node metadata ceiling. Because metadata is evenly distributed, excess metadata space available on larger nodes cannot compensate for insufficient capacity on the smallest participating node.
Therefore, the largest, newest, or oldest Storage Node has no special role in determining metadata sizing.
Hardware generation or installation age is irrelevant to this calculation; usable metadata capacity is constrained by the node with the least available metadata capacity.
