I passed exam CCNP router and trouble shooting
around 12/28/15 but i do not still pass switch..
I Know router and trouble shooting exam expire in 2018
but I passed CCDA and OCSE around 2017..
And then my CCNA was extend in 2020
I hope router and trouble shooting is extend...
so I want to know.. if I pass exam switch
Can I get CCNP certification? or do I have to get router and trouble shooting again ?
Yes if you pass a valid cisco exam(CCNA/Professional/Expert) all your other cisco exams you have already passed and have not yet expired will be extended
Differently to the others I doubt that this will work. To my understanding, only certifications (like CCNA, CCNP, ...) are extended when a new exam of the same or higher level is passed. But not the individual exams. And if the exam itself is expired and the certification is not yet reached, I think that these exams have to be done again. But I am not exactly sure here.
Youll have to take Route and TShoot all over. You have a three year period to take all three to be CCNP certified. CCDA will renew the CCNA as you saw but for CCNP, it doesnt count towards that. I was in similar situation late last year. Passed Route in Sept 2016. Thought taking Switch in 2019 would renew and keep CCNP path going for three more years. I was wrong. I just passed Switch last week and have to take TShoot by Sept. Unfortunately, youll have to start from square one for CCNP.
