You know, it really annoys me when someone makes a comment like this (Please note that this matter is covered in material needed for CCNA exam). I know this. I've been through it all and then some. Regardless of whether or not something "similar" to this is covered in the CCNA material, certain situations exist where things aren't "cut and dry", which is why I was trying to get opinions from others on this board. Did you read the original post? Why do people need to come off as being superior to others? Geez.

Thank you! There is distinct difference between bit errors and collisions. Retransmitting in a case of bit error or data loss would be error recovery procedure, which, as such, does not exist on Ethernet layer 2. On Ethernet network, this is, usually, accomplished by upper layer protocols (TCP is one example). Listening to collisions on the other hand is defined by protocol that Ethernet is using (CSMA/CD) and is not considered to be error recovery procedure. Please note that this matter is covered in material needed for CCNA exam. Marko.
