When the candidater receive a voteRequest with Higher Term, what should the candidater do?

Answer 1

If a Candidate receives a RequestVote RPC with a term higher than its own, it should convert to a Follower and grant its vote for that term to the node requesting it (assuming the log matching property is satisfied and there are no other RequestVote RPCs with an equal or higher term).
