Question: Distributed System: At-Most-Once semantic ensures that a given RPC request will not be executed more than once. There is an alternative RPC semantic called At-Least-Once

Distributed System:

At-Most-Once semantic ensures that a given RPC request will not be executed more than once. There is an alternative RPC semantic called At-Least-Once semantic, which ensures that each request is executed to completion. How do you implement these two semantics? For Idempotent operations, which semantic is generally more suitable? Can you name an application scenario where these two semantics can be used interchangeably?
