What are two reasons that cause late collisions to increment on an (CCNA 200-301)
What are two reasons that cause late collisions to increment on an Ethernet interface? (Choose two)
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.
Solution
Correct answer: B) when one side of the connection is configured for half-duplex and E) when the cable length limits are exceeded.
Late collisions occur in Ethernet networks when a collision is detected after the time it takes for the maximum allowed frame size to be transmitted. Here's an explanation for each option:
B) When one side of the connection is configured for half-duplex: In half-duplex mode, a device cannot send and receive at the same time. If both sides of the connection are not configured for the same duplex mode (half-duplex or full-duplex), it can lead to late collisions.
E) When the cable length limits are exceeded: Ethernet has specific cable length limits. If these limits are exceeded, it can result in signal propagation delays that may lead to collisions occurring too late in the frame transmission process.
The other options (A, C, and D) are not directly related to the causes of late collisions.
