Correct Answer: D. D. 255
Explanation: If we want that a character be interpreted by the client instead of server, we use the IAC character. If IAC is followed by any other code than IAC, the client interprets it as a character.

Correct Answer: A. A. Each character typed is sent by the client to the server
Explanation: In character mode, each character that the user is typing is immediately sent to the server which then interprets it only after the complete operation command is received.

Correct Answer: A. A. Default mode
Explanation: In the default mode, the client does not send each character typed by the user to the server, thus saving the amount of packet transmissions required for executing each operation. But the server has to remain idle until the client sends the completed line wasting a lot of time.

Explanation: DELETE operation should be idempotent, means their result will always same no matter how many times these operations are invoked. Also, the PUT operation is supposed to be idempotent.

Correct Answer: B. B. Private
