The correct answer is D. Configure a schedule for 1 minute up to 15 minutes. NearSync replication (option A) achieves RPOs of 1–15 minutes but has a hard prerequisite: all clusters involved - both source and destination - must have a minimum of 3 nodes. Single-node clusters do not support NearSync. With NearSync ruled out, the lowest achievable RPO…
Question

Options
- AConfigure NearSync replication.
- BConfigure a schedule for 16 minutes up to 59 minutes.
- CConfigure Async replication.
- DConfigure a schedule for 1 minute up to 15 minutes.

Explanation
NearSync replication (option A) achieves RPOs of 1–15 minutes but has a hard prerequisite: all clusters involved - both source and destination - must have a minimum of 3 nodes. Single-node clusters do not support NearSync. With NearSync ruled out, the lowest achievable RPO using standard asynchronous replication is a schedule of 1–15 minutes (option D). A schedule of 16–59 minutes (option B) provides a higher (worse) RPO. 'Configure Async replication' (option C) is too vague and does not specify the shortest possible interval.
