@Samuel-Bumbeh,
Anything that helps you to understand the concepts and workflow of DevOps is something that everyone working in IT that is NOT end user awareness should have some foundation in DevOps.
So regardless of whether it's the AWS DevOps or the Dev Associate from Cisco, it is the future.
In terms of whether it a certification will make you good at something is all up to you. It will at least make you competent in the main areas. I say this, not flippantly, for example DevOps itself will not make you good at Active Directory configuration and troubleshooting. You will have to become good at it. It may help you to understand how policies are implemented but maybe not whether this is effective. So this will have to be experience. that drive.
First, you'll have to decide on which CCNP you want to begin: There are several: https://www.cisco.com/c/en/us/training-events/training-certifications/exams/current-list.html#~certification-exams
then take a look at the exam topic coverage for each to know whether or not your plan will work for you.
In terms of what to do after CCNA for certification? I think you should take a look at the job you're aiming for or promotion or etc. to decide what is next. That is the best wisest use of your time, effort and even resources, imho.
Thanks for being a member!
