Will AWS certification help

Hi...my exp is 8 years and cctc is 25lpa as Java back end developer.

Now that I have your attention, please answer as per your knowledge

I am planning to study for AWS solution architect professional certification.

1. Can I give it directly? How much time will it take if I can decent amount of hours every week?

2. How much jump in salary it can give me in my current organization or outside?

Thanks
