A device detects two stations transmitting frames at the same time (CCNA 200-301)
A device detects two stations transmitting frames at the same time. This condition occurs after the first 64 bytes of the frame is received. Which interface counter increments?
A) runt.
B) collision.
C) late collision.
D) CRC.
Solution
Correct answer: C) late collision.
The scenario described typically indicates a collision, which occurs when two devices on a shared Ethernet segment transmit data simultaneously, causing their signals to interfere with each other. However, collisions are usually detected before the first 64 bytes of the frame are received.
In the given scenario, where the collision is detected after the first 64 bytes of the frame are received, it is referred to as a "late collision." Late collisions are often indicative of problems in the network setup, such as mismatched duplex settings or excessive cable lengths.
