CCNA: Cisco Certified Network Associate — Question 10

What are two reasons that cause late collisions to increment on an Ethernet interface? (Choose two.)

Answer options

• A. when Carrier Sense Multiple Access/Collision Detection is used
• B. when one side of the connection is configured for half-duplex
• C. when the sending device waits 15 seconds before sending the frame again
• D. when a collision occurs after the 32nd byte of a frame has been transmitted
• E. when the cable length limits are exceeded

Correct answer: B, E

Explanation

The correct answers are B and E. Late collisions occur when one side of the connection is set to half-duplex, which can cause collisions after the transmission has started, and when the cable length limits are exceeded, leading to signal degradation. Options A, C, and D do not directly contribute to the occurrence of late collisions in the same way.
