The Election service must ensure that a vote is recorded whenever any user thinks they have cast
a vote.
Discuss the effect of maybe call semantics on the Election service.
Would at-least-once call semantics be acceptable for the Election service or would you
recommend at-most-once call semantics?
What will be an ideal response?
Maybe call semantics is obviously inadequate for vote! Ex 5.1. specifies that the voter’s number is used to
ensure that the user only votes once. This means that the server keeps a record of who has voted. Therefore at
least-once semantics is alright, because any repeated attempts to vote are foiled by the server.
