問題文
A client that programs forwarding entries on a router loses its session, reconnects, and sends its first entry immediately, but the server does not accept it. What did the client owe the server before that entry?
選択肢
- The message that sets the session parameters, which has to be repeated before every entry so that the server can check the mode again.
- The message that sets the session parameters, which has to be the first one after a reconnect and has to match the values other clients use.
- A message that flushes the entries, which clears what the previous session left behind before any new entry is accepted.
- A message that sets the election value, which the server needs even when only one client is connected to it.
