Question:
Which action is performed by a client when establishing communication with a server via the use of UDP at the transport layer?

• The client sets the window size for the session.
• The client sends an ISN to the server to start the 3-way handshake.
• The client randomly selects a source port number.
• The client sends a synchronization segment to begin the session.

Explanation: Because a session does not have to be established for UDP, the client selects a random source port to begin a connection. The random port number selected is inserted into the source port field of the UDP header.
