Do I need to have access to the Alteryx Designer (Desktop) or Cloud as I prepare for the Alteryx Core Designer certification?
In order to complete the Alteryx Core Designer Certification test, you will need Altetryx Designer during the test for some questions.
If you are not client yet, the possible way I can imagine is to learn fast and complete the test with Altreryx tial version.
Alteryx is offering a 30-days trial now. but honest it will be a quite a challenge.
