A StorageGRID High Availability (HA) group provides active-backup access by assigning one or more virtual IP (VIP) addresses to the currently active interface. For site-level failover, the HA group includes suitable Admin Node or Gateway Node interfaces from both sites, and those interfaces must participate in a network design that allows the same VIP to move between sites. NetApp's StorageGRID site-failover guidance specifically describes including interfaces from Site 1 and Site 2 and assigning a VIP within the same subnet. If the preferred site's interface becomes unavailable, StorageGRID transfers the VIP to the next available interface at the other site.

Accordingly, the VIP subnet must be available across the participating sites; the same client-facing VIP remains usable after failover. StorageGRID requires the VIP and optional gateway to belong to the configured VIP subnet.

Option B is incorrect because multiple VIPs are not assigned as independent site-specific addresses for HA failover; all configured VIPs reside simultaneously on the active HA interface. Option C is invalid because the HA configuration requires IP addresses, not an FQDN. Option D confuses the optional gateway with the actual VIP.
