Trending @Accenture; Can anyone suggest me which school should I choose for my techleap which have higher chances of passing and have dumps available for it?

Go for AZ-900 or AWS cloud fundamentals. Dumps are available on telegram and higher chances of passing.

Short list schools that are relevant to your profile. Once that is done, your strategy should be to zero down on something that you are well versed with and/or is a course that can be completed in a shorter duration. All the best!

Depends on your stream and your manager needs to approve it. If they are ok you can go with Azure or Cloud domains..
