Which of the following statements about simple replication is incorrect?

Simple replication in data management systems typically involves transferring data from a source to a destination at defined intervals or schedules. This method of replication is beneficial for synchronizing data across different locations or systems while ensuring consistency. The key aspects of this process can be outlined as follows:

When considering the statements, the correct one indicates that replication indeed happens without relying solely on a designated schedule. In practical applications, many replication systems allow for the possibility of triggering replication events based on specific criteria, conditions, or triggers as opposed to being strictly constrained to a regular schedule. For example, a replication event might be initiated by changes in data or an external command, thereby offering flexibility in when data is replicated.

In contrast, options about replication schedules, interval-based data transfer, and the necessity for active source tags align with established principles of how simple replication functions. These clarifications illustrate that while there are methods that use a schedule, the ability for replication to occur outside of this structure exemplifies the versatility and adaptability of replication technologies.
