I was starting to answer your question, when I saw the second question. Really, you should just buy a good book. I recommend the official Cisco ICND1 study guide by Wendell Odom. If you learn that book cover to cover + practice, I'm sure you'll ace the test!


Good luck

Those are the port numbers and Transmission Layer Protocols from Odoms ICND1 book!

Know as many popular ones as you can, not just for the CCENT, but for real world. If you're at your job and somebody says they need a port opened for remote desktop for example, it's a lot quicker and easier knowing it right off the bat then going to look it up.

Your list looks good (as far as I can tell). I have not attempted that exam for many, many years, though (and it has changed significantly during that time) - so I would venture that if your textbook only covers these ports then you are probably good knowing just those ports.

BTW - what UDP / TCP port does EIGRP reside on? (Hint...this is a trick question)...


...How about RIP?


...How about OSPF?


...How about BGP?


Sorry, couldn't resist - every Cisco certified person should learn these...
