Dear @Narasimha1 ,
From the certification front, you should opt for Adobe Target Business Practitioner Professional (Exam AD0-E408). The link has the tabs for your to get ready, prepped, and certified.
To start the learning journey, you can always start with Adobe Experience League Tutorials which is free.
If your company is a Partner of Adobe, there are on-demand videos available in Solution Partner Portal, and can be super helpful.
However, if you don't have enough experience with the solution, clearing the certification would be super difficult since most of the questions would be based on use cases.
Practice, learn, and experience it before giving it a try for certification. All the very best.
