ICND1: Interconnecting Cisco Networking Devices Part 1 (CCENT, legacy) — Question 29

In which two ways does TCP differ from UDP? (Choose two.)

Answer options

• A. TCP provides synchronized communication.
• B. TCP segments are essentially datagrams.
• C. TCP provides sequence numbering of packets.
• D. TCP uses broadcast delivery.
• E. TCP provides best effort delivery.

Correct answer: A, C

Explanation

The correct answers are A and C because TCP is designed for reliable communication, ensuring that packets are delivered in order (sequence numbering) and that the communication is synchronized. Options B, D, and E are incorrect as TCP segments are not datagrams, TCP does not use broadcast delivery, and it does not provide best effort; that is characteristic of UDP.
