Selected Answer: B

Explanation: To minimize downtime and meet the strict SLA (≤10 min/month of downtime), the best approach is to: 1️⃣ Set up a replica database in the cloud. 2️⃣ Synchronize data continuously between the current (on-prem) database and the cloud database. 3️⃣ Switch over to the cloud database when synchronization is complete. This ensures minimal downtime (just the time it takes to redirect traffic to the new database).
