After successful attempts of 2X Marketo Business Practitioner Certification exams plus having around 5 years of working experience on the Marketo, what is the best practice to prepare for the Marketo Solution Architect Exam?
I strongly assume you know this page, right? https://express.adobe.com/page/NkbePPtTMD3qq/ There are sample questions here, and I guess that's already the best you can do. I am not aware of any other resources specifically for this cert.
Note also that everyone who passed this cert is not allowed to talk about it. That might be why it's so quiet in here. 🙂
