Get both of them.
CCENT is CISCO version of Network+. I'm in the process of studying for the ICND1 (CCENT test) and the Network+. So far, going over materials, they are practically nearly identicle.
Just go on Amazon and purchase one of the latest Network+ Study Guides. for like $30-40. (Recommend "Network+ for Dummies if you're really new to it) and once you study up through the book, challenge the Network+ exam.
However, I'd strongly recommend getting your A+. The background information in the A+ will help you considerably when trying to understand the material.
CCENT, just get a CCNA Library. I got mine used. I thas two books. One for the ICND1 exam (CCENT) the next is ICND2 (CCNA).
I got study books to both for a total of $37,89 as one package. Very detailed information. And they come with discs so you can use a "Simulator" to practice the features on them. Like setting up a WAN, interfaced with several different LANs. And troubleshooting issues in your network. WIthout having to buy a CISCO Router etc. etc. etc.
Forgot to add: After Network+ and CCENT are obtained, go and get your CCNA. (next test, ICND2), Security+, and CCSP. and just keep going up from there.
