1. In the Raft consensus algorithm, a node that initiates an election and requests votes from peers is called a:

2. In Raft, the numbered period that begins with a leader election is called a:

3. A distributed consensus algorithm requires that a majority of nodes acknowledge a write before it is committed. What is this majority called?

4. The Raft leader replicates log entries to followers before committing them. Followers apply committed entries to their state machines in the same order. What property does this ensure?

5. A node that has not received a heartbeat from the leader within the election timeout begins an election. What state did it detect?
