Reinitializing a Subscription and synchronization the subscription

Welcome to the forums.
Is this a interview Question?
The answer depends on the type of replication that is used here, from Books online : When you create a subscription, you can define a synchronization schedule that controls when the replication agent for the subscription will run. If you do not specify scheduling parameters, the subscription will use the default schedule.
By default, a subscription to a transactional publication is initialized with a snapshot, which is generated by the Snapshot Agent and applied by the Distribution Agent. In some scenarios, such as those involving large initial datasets, it is preferable to initialize a subscription using another method.
