Case 1:

Question:
What are three characteristics of the TCP protocol? (Choose three.)

• It uses a single SYN-ACK message to establish a connection.
• The connection is established before data is transmitted.
• It ensures that all data is transmitted and received by the remote device.
• It supports significantly higher transmission speeds than UDP.
• It requires applications to determine when data packets must be retransmitted.
• It uses separate SYN and ACK messages to establish a connection.

Explanation: Answer F is not correct because TCP does not require applications to determine the retranmission. TCP itself will determine if the data packets should be retransmitted or not.
