NEW QUESTION # 47
You have a 4-node NetApp ONTAP cluster that has been using FabricPool technology to tier data to a dedicated StorageGRID endpoint on a grid composed of two Admin Nodes, two Gateway Nodes in an HA group, and four Storage Nodes. After one year, your ONTAP cluster displays an error connecting to the grid to tier data. You have no reports of issues with any other applications or users on your StorageGRID system.
What is the cause of the error?
Answer: B
Explanation:
FabricPool normally connects ONTAP to StorageGRID through an HTTPS load balancer endpoint. That endpoint uses a server certificate so that ONTAP can authenticate the StorageGRID service. NetApp specifically warns that if the certificate securing the ONTAP-to-StorageGRID connection expires, FabricPool temporarily stops working and ONTAP loses access to data tiered to StorageGRID.
The same problem can occur when the endpoint certificate is renewed or replaced in StorageGRID but the corresponding trusted certificate on ONTAP is not updated. NetApp requires the StorageGRID and ONTAP certificate configurations to remain synchronized; after certificate replacement or renewal, ONTAP must trust the new certificate chain.
The scenario also eliminates the node-failure answers. The two Gateway Nodes are configured in an HA group, so failure of one Gateway Node should not independently cause the FabricPool endpoint to become unavailable. Likewise, losing one Storage Node does not normally prevent access to the StorageGRID S3 service. A Client Network trust-state change would have broader networking implications and does not fit the isolated, time-related FabricPool failure described.
Therefore, C is the correct answer.

NEW QUESTION # 48
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.

NEW QUESTION # 49
You are installing a NetApp SG5860 appliance with the Grid Network and Client Network enabled.
Which two configurations are supported for the Grid and Client networks using the four interfaces? (Choose two.)
Answer: A,B
Explanation:
For the SG5860, which uses the SG5800 controller, StorageGRID supports both Fixed and Aggregate port- bond configurations. In Fixed mode, ports 2 and 4 are paired for the Grid Network and ports 1 and 3 for the Client Network. Active-Backup is the default network bond mode, and VLAN tagging is optional; therefore, the two-port Active-Backup configuration in A is supported.
In Aggregate port bond mode, all four 10/25-GbE ports form a single LACP (802.3ad) bond carrying both Grid and Client Network traffic. Because both networks share the aggregate, StorageGRID requires a unique VLAN tag for each network, making C the supported aggregate configuration. A four-port Active-Backup aggregate is not supported, eliminating B.
Verification note: the current NetApp SG5800 appliance documentation also permits two-port LACP bonds in Fixed mode, with VLAN tagging optional. Consequently, option D is technically supported as written, making this question ambiguous against current documentation. If restricted to the intended two-answer certification key representing the standard Fixed Active-Backup and Aggregate LACP configurations, A and C are the expected selections.

NEW QUESTION # 50
Your customer has a two-site StorageGRID system, with three Storage Nodes on each site. The customer wants to always read the last written version of an object. They have set up the information lifecycle management (ILM) policy to write a single copy to each site. They have set the ingest policy to Strict and the consistency profile to strong-global. During maintenance on a node on Site-2, an additional node on that site fails, and end users complain about being unable to upload objects to the grid.
What is the cause of these errors?
Answer: A
Explanation:
The failure is caused by the strong-global metadata consistency requirement, not by the Strict ILM placement requirement. StorageGRID stores object metadata in Cassandra, normally maintaining three metadata replicas per site. With three Storage Nodes at Site-2, taking one node down for maintenance and then losing another leaves only one metadata replica available at that site. The required metadata quorum can no longer be achieved for strong-global operations. NetApp documents that strong-global guarantees read-after-write consistency across all sites and requires sufficient metadata replicas to complete the operation.
The distinction from Strict ingest is important. Strict controls object-data placement: all copies specified by the ILM rule must be created before StorageGRID returns success. Here, the ILM rule requires only one copy at each site. Because one Storage Node remains operational at Site-2, StorageGRID can potentially place the Site-2 object copy there. Therefore, the data-placement requirement itself is not necessarily violated.
However, with two of the three metadata-bearing Storage Nodes unavailable at Site-2, Cassandra cannot satisfy the strong-global metadata consistency requirement, causing client PUT operations to fail.

NEW QUESTION # 51
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: D
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.
