What might be occurring if there are peaks of traffic flow from the primary to a hot site?

1. Synchronous replication

2. Asynchronous replication

3. File transfer

4. Continuity updates

The correct answer is: Synchronous replication

Synchronous replication is the correct response because it involves real-time data transfer, ensuring that data written to the primary site is simultaneously written to the hot site. This technique results in peaks of traffic flow since data packets are consistently sent across the network to maintain an exact duplicate of the information at the secondary site. This high level of traffic is characteristic of synchronous replication, which is essential for environments where data integrity and immediate availability are critical. In contrast, asynchronous replication sends data to the secondary site after a delay, meaning that not all updates happen simultaneously and thus would not cause continual peaks in traffic. File transfers, while they may involve significant data movement, do not guarantee continuous replication of data changes and can occur at scheduled intervals rather than in real-time. Continuity updates may involve various tasks for maintaining system readiness and availability but do not specifically relate to the constant data flow that characterizes synchronous replication.
