A network administrator is setting up a server architecture where it is essential to ensure that if a data transmission is interrupted, the process can be resumed from the checkpoint rather than restarting. Which feature of the OSI model's Session layer is particularly useful to achieve this requirement?
The correct feature is 'synchronization', which provides a way for a session to insert checkpoints into data streams, thus allowing a restart at the last checkpoint in case of interruptions, without needing to resend all data. This is crucial in saving bandwidth and ensuring efficient communication. 'Dialog control' manages who can transmit data at a given time, and 'token management' mainly concerns with preventing overlap of communication but doesn't ensure data integrity through checkpoints. 'Connection termination' is a routine process to end a session, not related to handling interruptions in data transmission.
