Carrier sense multiple access with collision detection (CSMA/CD) was specifically developed to deal with collisions on wired Ethernet networks. It works by detecting collisions after they happen and then taking steps to mitigate them, such as waiting a random time before retransmitting. This is a suitable mechanism for a network where traffic is transmitted simultaneously from different nodes, as it can still handle collisions that occur in these situations.
Token ring doesn't make sense as it specifically lists "multiple nodes." The whole point of token ring is that you don't communicate if you don't have the token. CSMA/CA is for Wi-Fi CSMA/CD is for Ethernet Since it says wired, the only answer that makes sense is CSMA/CD
I'm confused, are you saying the token ring doesn't make sense because above it states above "simultaneously transmitted from different nodes"? Or did that part get looked over and it didn't make sense because token-passing is the actual process of passing the token to nodes in order to transmit? CSMA/CA isn't correct because it's not a wired network. Either way, token-passing is 100% the correct answer. In order to "talk" you need to hold the "special token," or else you sit there silently. It's a black-and-white situation and completely avoids collisions.
CSMA/CD is collision detection, not avoidance, even though it tries its best to avoid it. The issue is when two nodes want to transmit at the same time. If both channels kick on their random timer for x amount of time. Channel 1 ends up having a smaller wait time because it's randomized and it starts to transmit its frame. Channel 2 is just kicking it waiting and sees the frame come in. Now channel 2 starts to talk, but channel 1 isn't finished so they collide. Now they set the timer again and give it another shot, if they collide again channel 2 waits longer for the next randomized wait time. Now channel 1 gets more freedom to talk, and it will most likely cause yes, another collision until channel 2's timer is so long that channel 1 basically owns that entire path. The only way they could have played on words here to make CSMA/CD the victor is if they had used "ethernet network" instead of "wired network" Token runs on (typically) type 6 or type 3 STP/UTP cable which is used in telephone circuits.

bzpunk is right. The answer is B - CSMA/CD
Answer is B CSMA/CD.
The mechanism created to overcome the problem of collisions that occur on wired networks when traffic is simultaneously transmitted from different nodes is D. Token-passing1. This method ensures that only one device at a time has the right to transmit data, preventing collisions. In contrast, Carrier sense multiple access with collision detection (CSMA/CD) is used in Ethernet networks and allows devices to listen for a clear channel before transmitting data, but it does not prevent collisions. The other options, Carrier sense multiple access with collision avoidance (CSMA/CA) and Polling, are not specifically designed to address collision problems in wired networks. So, the correct answer is D. Token-passing.
