Hi,
You'll find the certificate requirements on the MCSD: App Builder certification page. To earn the MCSD: App Builder certification, complete the following requirements:
Earn one prerequisite certification:
- Prerequisite Option 1: MCSA: Web Applications
- Prerequisite Option 2: MCSA: Universal Windows Platform
And pass one of the elective exams:
- 70-357: Developing Mobile Apps
- 70-486: Developing ASP.NET MVC Web Applications
- 70-487: Developing Microsoft Azure and Web Services
So in other words, if you take both 70-468 and 70-487 exams and pass them both, you will receive the MCSD: App Builder certification.
