Common operational misconceptions

I find a lot of new folks have a hard time with the difference in 
port numbers and protocol numbers.  

I just went through this with a CC<something-more-than NA>, but with 
virtually no hands-on experience a few minutes ago.  Very disturbing 
when a person can take the higher level tests, but still can't 
understand the basics.  All they do is use the certification testing 
programs and memorize everything they can.  :-(

grrr....
