NetApp Cloud Volumes ONTAP provides several storage efficiency features that help optimize cloud storage costs. Two of the key methods for reducing costs are:

Thin Provisioning: This feature allows users to allocate more storage capacity than is physically available. Instead of reserving full storage at the time of volume creation, space is only consumed as data is written. This reduces upfront costs and optimizes storage use by delaying actual storage allocation until necessary, making it cost-effective.

Volume Deduplication: Deduplication removes redundant copies of data within a volume, reducing the total storage footprint. By eliminating duplicate blocks of data, volume deduplication significantly cuts down on the amount of storage consumed, leading to lower storage costs in the cloud environment.

Other options like "aggregate deduplication" and the "TCO calculator" are not direct methods to optimize storage costs. Aggregate deduplication is not as granular as volume deduplication, and the TCO calculator is a tool for estimating total cost, not a method for optimization.

NetApp StorageGRID provides high availability (HA) by leveraging several key technologies, and one of the primary benefits in an HA environment is the use ofvirtual IP addresses (VIPs). In a high-availability configuration, StorageGRID uses VIPs to ensure continuous access to the service, even if one of the StorageGRID nodes becomes unavailable.

By using VIPs, StorageGRID ensures that requests to the system can be dynamically rerouted to an available node, providing seamless failover and reducing downtime in the case of node failures. This ensures that clients continue to connect without disruptions, contributing to the overall resilience and availability of the environment.

While options like zero data loss (B) are important, they are not guaranteed in every failover scenario without a well-designed backup or data replication system. Focusing on data retrieval speed (C) or single-instance redundancy (D) doesn't directly pertain to how NetApp StorageGRID handles high availability.

In a Multi-AZ (Availability Zone) setup for NetApp Cloud Volumes ONTAP in AWS, ensuring nondisruptive failover between nodes is critical for high availability. "Floating IPs" are required for seamless failover between nodes in such a configuration.

Floating IPs allow the primary node to automatically transfer its IP address to the secondary node during a failover event, ensuring that clients can continue to access the service without needing to reconfigure anything. This mechanism enables clients to access the same IP regardless of which node in the cluster is actively serving requests, thus maintaining nondisruptive operations.

Elastic Network Interfaces (ENIs) facilitate networking in AWS but do not inherently handle IP floating between nodes for failover. Security groups and Intercluster UFs manage security and inter-node communication, respectively, but do not address the failover requirements. Floating IPs are explicitly designed to enable failover in high-availability cloud storage environments like NetApp Cloud Volumes ONTAP.

Thus, "floating IPs" are the required network construct that allows for nondisruptive failover between nodes in a multi-AZ setup, ensuring continuous service availability even in the event of an outage in one availability zone.
