Hi @Giuseppe Ardito ,
As per the Microsoft exam retake policy states:
If a candidate does not achieve a passing score on an exam the first time, the candidate must wait 24 hours before retaking the exam. At that time, candidates can log onto their certification dashboard and reschedule the exam themselves. If a candidate does not achieve a passing score the second time, the candidate must wait at least 14 days before retaking the exam a third time.
Please also note that Microsoft Certification / Exams is currently not supported in the Q&A forums, the supported products are listed over here https://learn.microsoft.com/en-us/answers/products.
You can ask the experts in the dedicated Microsoft Certification - Exams - Exam Registration and Scheduling forum over here:
