Q77 / 100

What is the difference between "synchronous replication" and "asynchronous replication" for databases?

Correct! Well done.

Incorrect.

The correct answer is A) Synchronous replication waits for replicas to acknowledge a write before confirming it to the client, ensuring stronger consistency at the cost of latency; asynchronous replication confirms writes before replicas catch up, risking data loss on failover

A

Correct Answer

Synchronous replication waits for replicas to acknowledge a write before confirming it to the client, ensuring stronger consistency at the cost of latency; asynchronous replication confirms writes before replicas catch up, risking data loss on failover

Explanation

Synchronous replication trades latency for durability guarantees, while asynchronous replication improves write latency but can lose recently committed data if the primary fails before replicas catch up.
