Please help me understand something. CCENT is a new certification? The test requirement is ICND1? And CCENT/ICND1 and ICND2 make the CCNA? I ask because I was interested in taking the two test path but I didnt want to take that route and be just half certified. You know kind of half way to nowhere type deal. Is there a time limit between exams before I can take the second test. How long does the ICND1 last?
