NEW QUESTION # 28
An existing StorageGRID system spans three sites. A fourth site will be added and will only store local data with a 2+1 information lifecycle management (ILM) policy.
What StorageGRID component requires network bandwidth and latency sizing between all four sites?
Answer: B
Explanation:
The correct answer is metadata updates. StorageGRID maintains object metadata independently from object data, using the distributed Cassandra database. NetApp specifies that StorageGRID stores three copies of the metadata for every object at each site, meaning every site maintains metadata for all objects in the grid, regardless of where the object data itself is physically stored.
This distinction is critical in the scenario. Even though the new fourth site uses an ILM policy that keeps its object data local with a 2+1 protection scheme, metadata activity is still grid-wide. NetApp explicitly states that administrators must consider network bandwidth and latency between sites because metadata updates are continually replicated between sites even when all object copies remain at the site where they were ingested.
Therefore, the WAN links connecting all four sites must be sized to support continuous metadata synchronization.
Load balancer endpoints handle S3 client connectivity and do not create this universal intersite requirement.
NTP requires reliable time synchronization but is not the workload driving the stated bandwidth-sizing requirement. Storage pools are logical ILM constructs and do not themselves replicate metadata.
Therefore, B. metadata updates is the required component.

NEW QUESTION # 29
A customer created several S3 load balancer endpoints, one of which should be accessible only to a specific tenant that is used for internal backups.
How can you meet this requirement?
Answer: D
Explanation:
StorageGRID load balancer endpoints can be restricted so that only selected tenant accounts are permitted to use a specific endpoint. During endpoint configuration, the administrator uses the Tenant access setting and selects Allow selected tenants, then chooses the backup tenant account. NetApp states that with this setting, only the selected tenant accounts can use the endpoint to access their buckets. This directly satisfies the requirement to dedicate one S3 load balancer endpoint to the internal-backup tenant.
Option A is incorrect because a global binding mode determines where the endpoint is available across eligible Admin and Gateway Node interfaces; it does not restrict access by tenant identity. Option D similarly limits the endpoint to interfaces associated with particular HA groups, which controls network exposure rather than tenant authorization. Option B is not a valid per-tenant isolation mechanism because HTTPS configuration applies to the endpoint connection itself and cannot be selectively disabled for unrelated tenant accounts.
Therefore, the required control is to configure the load balancer endpoint's tenant-access settings and assign access specifically to the backup tenant.

NEW QUESTION # 30
You have a StorageGRID system that spans multiple sites. You are asked to create an S3 bucket for extremely important objects that require all sites to receive metadata immediately after any new write or change.
When creating this S3 bucket, which consistency level meets the requirement?
Answer: C
Explanation:
The appropriate consistency level is strong-global because the requirement explicitly applies to clients and object metadata across multiple StorageGRID sites. NetApp defines strong-global as providing read-after- write consistency for all client requests across all sites. Therefore, after an object is created or its metadata is changed, subsequent requests from any site receive a consistent view of that change.
strong-site is insufficient because its consistency guarantee applies only to client requests within a single site.
A client accessing the bucket from another StorageGRID site could therefore fall outside the required site- wide consistency guarantee. read-after-new-write, which is the default and generally recommended setting, guarantees consistency for newly created objects but provides eventual consistency for object updates.
Because the scenario requires immediate consistency following both new writes and changes, it does not meet the stated requirement. available provides eventual consistency for both new objects and updates and prioritizes availability rather than cross-site consistency.
Thus, among the available options, strong-global is specifically designed for workloads requiring globally consistent object and metadata visibility across a multisite StorageGRID deployment.

NEW QUESTION # 31
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,D
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 # 32
Your customer has a requirement to create external backups of some of their buckets, where all backup objects are to be retained for at least 90 days, including all possible versions. Your customer already created a new standalone grid on the new location.
What steps provide a solution for this requirement?
Answer: A
Explanation:
The correct architecture combines S3 versioning, cross-grid replication (CGR), and ILM retention.
StorageGRID cross-grid replication operates between two StorageGRID systems connected through grid federation and requires the participating source and destination buckets to have versioning enabled. Critically, CGR creates versioned objects at the destination and replicates the source version ID, preserving the ordering of object versions between the grids. This directly satisfies the requirement to protect all possible versions.
After replication, each grid independently applies its active ILM policy to the objects stored locally. The backup grid can therefore use ILM rules to retain replicated objects for at least 90 days. StorageGRID ILM also supports rules specifically targeting noncurrent versions of versioned S3 objects by using Noncurrent time as the reference time, allowing previous versions to be retained for the required period.
Options A and B are unsuitable because nonversioned buckets cannot preserve every object version. Option C correctly identifies versioning and CGR, but a bucket policy governs access permissions; version retention is instead controlled through ILM or an S3 lifecycle configuration.
