Hi Bqwire,
Thank you for contacting the Microsoft Community.
Let me further give assistance with your exam DA-100 and in confirming the available training for it.
Please be informed that the Jobseeker/Covid-19 USD15 offer of PSI was already ended last December 31, 2021, as to why it is now at a regular cost. Also, the contract with Microsoft has been ended.
I looked for a training event and did not find one for MS-900.

You may refer to the table below as a guide for the eligible exams with their corresponding event name:
