NEW QUESTION # 34
During the design phase of a StorageGRID implementation project covering three geo-distributed sites, a requirement is identified to provide seamless access to object storage based on the proximity of the client to the nearest StorageGRID site.
Which solution meets the requirement?
Answer: C
Explanation:
A Global Server Load Balancer (GSLB) is the appropriate solution when StorageGRID client traffic must be intelligently directed among multiple geographically distributed sites. NetApp states that global load balancing integrates with DNS to provide intelligent routing across StorageGRID sites and can direct clients to the closest destination site, while also detecting site outages and redirecting requests to another available site. This global routing functionality is provided through a supported third-party load-balancing or DNS traffic-management solution.
A typical architecture combines GSLB at the global layer with site-local load balancers or StorageGRID Gateway Node HA groups. When an S3 client resolves the StorageGRID endpoint FQDN, the GSLB selects the appropriate site's virtual IP based on factors such as availability and network latency, thereby providing proximity-based client access.
Option B provides effective local site load balancing, but by itself does not choose the geographically closest site. Option A provides HA for interfaces within an HA group and is not a geographic traffic-management mechanism. Option C provides link-level redundancy and bandwidth aggregation rather than application-level site selection.
Therefore, D is the correct answer.

NEW QUESTION # 35
An enterprise is expanding a single-site StorageGRID deployment and is adding new nodes on a new subnet.
What is a requirement for configuring the Grid Network?
Answer: A
Explanation:
When an existing StorageGRID deployment is expanded with nodes whose Grid Network IP addresses are on a subnet that has not previously been used, that subnet must be added to the Grid Network subnet list before the expansion is started. StorageGRID maintains this list so that every grid node can correctly route internal Grid Network traffic to the other participating subnets. NetApp StorageGRID 12.0 documentation explicitly states that if any new node uses a new Grid Network subnet, the administrator must add that subnet first; otherwise, the expansion must be cancelled, the subnet added, and the expansion restarted.
The configuration is performed in Grid Manager # Maintenance # Network # Grid Network, where the administrator selects Add another subnet and enters the network in CIDR notation. StorageGRID then distributes the routing configuration throughout the grid.
Option A is incorrect because routes do not need to be configured manually on every node. Option B is incorrect because a StorageGRID Gateway Node provides client load-balancing functions and is not an IP router between Grid Network subnets. Option D is also incorrect; StorageGRID explicitly supports multiple Grid Network subnets, provided they are routable through the configured Grid Network gateway.

NEW QUESTION # 36
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
NEW QUESTION # 37
A customer wants to expand their existing StorageGRID system, which currently serves only cold data via FabricPool, to maximize usable object storage in a single-site installation.
Which actions achieve this?
Answer: C
Explanation:
For a capacity-focused FabricPool repository containing predominantly cold object data, the most efficient expansion method is to add a data-only Storage Node. StorageGRID 12.0 supports combined, metadata-only, and data-only Storage Nodes. A data-only node is dedicated to object-data storage and does not participate in Cassandra metadata storage, making it particularly appropriate when the primary objective is to maximize usable object capacity rather than increase metadata capacity. NetApp specifically describes data-only, high- capacity Storage Nodes as appropriate when dedicated capacity is required.
After the node is added, erasure-coded data can be rebalanced so that existing EC fragments are redistributed across the original and newly added Storage Nodes. NetApp states that EC rebalancing redistributes erasure- coded fragments among Storage Nodes at the site, allowing newly added capacity to be utilized by an existing EC protection scheme.
Option D adds usable capacity, but a combined node also provides metadata/Cassandra functionality that is unnecessary when the goal is specifically to maximize object-data capacity for a cold FabricPool workload.
Options B and C are not supported StorageGRID capacity-expansion strategies; appliance RAID/DDP configuration and SANtricity LUN sizing must not be arbitrarily changed to enlarge StorageGRID object storage.

NEW QUESTION # 38
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: D
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.
