Dear Sir/Madam,
Hope this email finds you well. We have been trained to do the AZ-900 exam. The training center will provide the exam vouchers. However, I attended Microsoft free training event and they gave me free voucher and used it, i.e. I used the free voucher provided by Microsoft.
Now I am planning to do DP-100, would it be possible to upgrade the voucher provided by my training center to DP-100 and pay the difference ($66)?
Kind Regards,
Sayed
