252. Why is there a limit to the number of MAUs that can be connected together in a standard Token-ring network?
     1. Too many MAUs would exceed the cable limits imposed by the Token Ring specification
     2. Too many MAUs would create to large of a collision domain for communications to take place
     3. Too many MAUs require more electricity than the devices can support
     4. Too many devices connected through MAUs requires more time to get control of the token that communications becomes unacceptable
     5. There is no limit to the number of MAUs a token ring network can support

     Answer: D

253. How many devices can communicate simultaneously within a Token-ring LAN?
