I’ve mentioned a few programs that Microsoft runs that offer free exam vouchers for the AZ-900 exam. I’ve heard recently that this exam voucher is restricted to the AZ-900 exam and can no longer be used for other exams.
And recently Microsoft offered an exam voucher for completing a challenge at Ignite.
But, year-round, you can get discounted Microsoft exam vouchers that have a short expiry date.
For instance, at the time of writing, you can buy a $165 exam voucher for $125, that expires on Dec 15, 2020.
(Note that this voucher is only good for the US, Canada, Australia, Denmark, Sweden and a few other countries.)
