A customer is looking to implement NetApp StorageGRID in a high-availability (HA) environment.

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.
