Answer: Deploying Amazon RDS across multiple Availability Zones
The correct answer is C, Amazon RDS with multiple Availability Zones. This configuration provides high availability and fault tolerance by automatically replicating the database across different data centers in separate Availability Zones. In the event of a failure or outage in one Availability Zone, Amazon RDS will automatically failover to a standby replica in another Availability Zone, ensuring minimal downtime and maintaining database accessibility. This is the recommended solution for companies requiring a highly available and fault-tolerant PostgreSQL database in Amazon RDS.
