Show Suggested Answer

Suggested Answer: E 🗳️
Snapshot replication distributes data exactly as it appears at a specific moment in time and does not monitor for updates to the data. When synchronization occurs, the entire snapshot is generated and sent to Subscribers.
Using snapshot replication by itself is most appropriate when one or more of the following is true:
✑ Data changes infrequently.
✑ It is acceptable to have copies of data that are out of date with respect to the Publisher for a period of time.
✑ Replicating small volumes of data.
A large volume of changes occurs over a short period of time.

Use transactional replication when it is important to have near real-time communication between database servers (SQL and non-SQL database servers). Otherwise just use snapshot replication.
