It looks like Cisco is doing away with the CCENT certification. If you pass your ICND1 before February 2020, you will still obtain the certification, and it will be valid for 3 years, however, if you want to get your CCNA after that, there will not be any ICND2 exam after February to get your CCNA. You will have to take the full fledged CCNA 200-301 exam from scratch.
So if you pass ICND1 before the deadline and you run out of time for ICND2, then you will have to take the whole 200-301 exam to get your CCNA. In other words, ICND1 doesn’t offer you any benefit for getting your CCNA after Feburary 2020.
My suggestion would be to try to get your CCNA before February, either taking ICND1 and ICND2, or the CCNA composite exam. It’s worth it because of the fact that the study content (on this and other sites) has fully matured and perfectly covers the topics. The new exam is still new, and content is still being developed to be able to study for it and pass it. Not that it is impossible, but it will just be that much easier.
If not, not to worry! We’ll still be here to support you and help you reach your certification goals!!
I hope this has been helpful!
