CCNA: Cisco Certified Network Associate — Question 114

What are two benefits that the UDP protocol provide for application traffic? (Choose two.)

Answer options

• A. UDP traffic has lower overhead than TCP traffic
• B. UDP provides a built-in recovery mechanism to retransmit lost packets
• C. The CTL field in the UDP packet header enables a three-way handshake to establish the connection
• D. UDP maintains the connection state to provide more stable connections than TCP
• E. The application can use checksums to verify the integrity of application data

Correct answer: A, E

Explanation

Option A is correct because UDP indeed has lower overhead than TCP, making it faster for certain applications. Option E is also correct as UDP allows applications to use checksums for verifying data integrity. The other options are incorrect because UDP does not have a built-in recovery mechanism (B), does not use a three-way handshake (C), and does not maintain connection state (D).
