Hi Hiromi,

Thank you for contacting the Microsoft Community. 

We recognize the importance of obtaining clarification regarding the use of test vouchers for your AI-900 exam, particularly as it relates to the retake process, allow me to take immediate action to assist you.

Please be advised that if your inquiry pertains to test vouchers issued through events, kindly note that each voucher code is valid for a single exam attempt only and cannot be reused following an unsuccessful attempt. Any subsequent attempt will be treated as a new exam registration and will require payment of the applicable exam fee, regardless of whether the initial attempt was covered by a voucher. Note that Microsoft enforces a formal exam retake policy, including mandatory waiting periods between retakes.

To enhance your likelihood of success, it is recommended that you thoroughly review the Exam AI-900 Study Guide, explore the Exam Sandbox, and take a practice test in advance. Additionally, consider utilizing the Exam Replay offer to further increase your chances of achieving a favorable outcome.
