200-301 Exam - Question 19


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

Show Answer
Correct Answer: BE

Late collisions occur primarily due to two key factors. Firstly, when one side of the connection is configured for half-duplex, it can lead to a duplex mismatch, causing late collisions. Secondly, when the cable length limits are exceeded, it results in signals taking too long to propagate, increasing the likelihood of late collisions. These factors are critical in maintaining a properly designed Ethernet network.

the right answer is B_E cause the selected one . when Carrier Sense Multiple Access/Collision Detection is used was the result f the collision domain but not the reason Join me to discuss more over my blog https://wa.me/50947163627

half-duplex as it is, can't be a cause of collision.

Directly from a Cisco article. What are two reasons that cause late collisions to increment on an Ethernet interface? (Choose two) A. when the sending device waits 15 seconds before sending the frame again B. when the cable length limits are exceeded C. when one side of the connection is configured for half-duplex D. when Carrier Sense Multiple Access/Collision Detection is used E. when a collision occurs after the 32nd byte of a frame has been transmitted Answer: B, C A late collision is defined as any collision that occurs after the first 512 bits (or 64th byte) of the frame have Been transmitted. The usual possible causes are full-duplex/half-duplex mismatch, exceeded Ethernet cable length limits, or defective hardware such as incorrect cabling, non-compliant number of hubs in the network, or a bad NIC. Late collisions should never occur in a properly designed Ethernet network. They usually occur when Ethernet cables are too long or when there are too many repeaters in the network.

Given Answer B & E are correct! ******* A late collision is defined as any collision that occurs after the first 512 bits (or 64th byte) of the frame have Been transmitted. The usual possible causes are full-duplex/half-duplex mismatch, exceeded Ethernet cable length limits, or defective hardware such as incorrect cabling, non-compliant number of hubs in the network, or a bad NIC. Late collisions should never occur in a properly designed Ethernet network. They usually occur when Ethernet cables are too long or when there are too many repeaters in the network.

Late Collision is a collision on an Ethernet network that is detected late in the transmission of the packet. Late collisions can result from defective Ethernet transceivers, from having too many repeaters between stations, or from exceeding Ethernet specifications for maximum node-to-node distances the right answer is B_E

B- E is the correct answer, search on google on the 2 reasons that cause late collision B- E is the correct answer 100%

B is not a correct answer because at CSMA/CD mode, end points cannot send and receive frames at the same time. Therefore end points(NIC) have to be in half-duplex mode. B is not a cause of late collision. But A can detect collision but also not the cause of late collision. All in all there is issue in the description of the question itself.

I'm going to have to agree with the cited cisco literature. They specifically site long cables and repeaters which are half duplex.

CSMA/CD happens before any collision,not after. So,option A can be kicked out at first glance... option B & E are valid

The answer is BE

Correct is B and E. B . If you use Half -Dublex it cause collusion. It doesnt matter both side is half-dublex. If it is full dublex than no collusion. E. This is clear. If cable is long than limit, it cause late collision. Why not A? Because CSMA/CD is not cause. It is for to stop collusion. It is the reason..
