@Edgar-David ,
I think so. Microsoft's website says "Candidates for this exam must have expert Azure administration skills."
Based on the objectives and working with WVD, I would think familiarity with the Azure portal, and other tools (Azure PowerShell and Azure CLI) would be helpful. Knowledge of deploying resources using ARM templates as well. Az-104 would be great, at least going through the material, if not taking the exam.
Here is a link to the current exam objectives:
