The ICND1 Exam is the first out of two tests that you will need to take in order to get your CCNA (Cisco Certified Network Associate). The CCNA Certification used to be the first certification that you could get from Cisco, but a few years ago they split it up into two tests. You can still take one big test to get your CCNA but I recommend splitting it up and going to the two test route.
The two tests are the ICND1 Exam and the ICND2 Exam. By passing the ICND1 Exam you will become a CCENT (Cisco Certified Entry Networking Technician). When you pass the ICND2 Exam, after you have passed the ICND1 Exam, you will become a CCNA. Just as if you had taken only the CCNA Exam.
This study guide is geared to help you pass the ICND1 Exam and get you started on an excellent career path as a Cisco Certified Networking Technician.
