As part of the new exam policy, learners can only have a maximum of two Microsoft Certification exams scheduled at a time, either on the same day or on separate days through Pearson VUE. You can always schedule another certification exam after each one you take or cancel. You may visit this sticky post for additional information.
If you have additional questions or clarifications, please let me know.
