I would like to register for the Data Engineer Associate exam. I have also passed the Databricks Lakehuse Fundamentals accreditation (id: 61076337), but on the registration site: https://www.webassessor.com/ does not allow me to purchase the exam, but requires a voucher.

Is this voucher compulsory? How can I get one? Is it possible to register for the exam without a voucher?

Thank you, best regards.
