Which statement about StorageGRID consistency levels is true?

• A. StorageGRID supports Available, Balanced, and Strong-global
• B. StorageGRID supports Available and Balanced only
• C. StorageGRID supports Strong-global only
• D. StorageGRID supports No consistency options

Answer: (A)

StorageGRID lets you choose how strictly it enforces data across distributed sites, which affects latency and data freshness. The three available consistency levels are Available, Balanced, and Strong-global. Available prioritizes uptime and availability, so reads and writes can proceed even if some replicas are down, but reads may return stale data. Balanced offers a middle ground, giving stronger consistency than Available while keeping latency reasonable. Strong-global provides the strongest guarantee by coordinating across all sites, ensuring writes are durably stored everywhere before acknowledging, at the cost of higher latency. So the statement that StorageGRID supports Available, Balanced, and Strong-global is correct. The other options imply missing or no consistency options, which isn’t accurate.
