This certification is achieved when passing the DA-100 Exam, which I have written a blog post about above. It is about Power BI and it is Microsoft that gives it out. My first tips about this certification is that is more focused on practical experience than many other certifications.
If you chose to take this certification without practical experience I would really encourage you to spend some extra time regarding Power BI Service, administration settings and about the different payment plans. It is more questions regarding this than what you think when reading the exam outline.
This exam is also from Microsoft and is more focused toward Data Science. If you plan to take this certification without practical experience I would really recommend to take the Microsoft Learning path, learn the basics about Machine Learning, as well as trying to learn the basics of Python.
The exam is quiet heavily focused on the Python SDK, therefore the Python Language is important for this exam. Besides this there are quite a lot of questions regarding the theory of Machine Learning.
This exam is the "Medium" exam given by Tableau regarding Desktop Certifications. I have written a blog post regarding this above. One tips for this exam is to understand to a good extend about how to do the easy visualizations quickly. In that way you will have more time for the more advanced questions.
Besides this I would emphasize the things I wrote in my blog post, like that you are actually able to google during the exam, so learn how the Tableau Help Documentation is built up and how to find answers there quickly.
This exam is the easiest of the Tableau exams. I have written a blog post regarding this one in the same post that I wrote about the other Tableau certification above. This certification is about the basics about Tableau and I would say that you do not really need practical experience to pass this.
Read through the Exam outline that Tableau have on their homepage, try to understand every bullet point there, and make use of the different resources that I have discussed in my blog post.
This certification is regarding the fundamentals of the Azure platform. The best tips I can give for this is to get an Azure account and try out all the other parts of the Azure platform.
Besides this the Microsoft Learning Path for this one is really good I think. If you go through all the learning path thoroughly this will probably be enough to pass the certification.
This exam is regarding the Microsoft Platform and is also given out by Microsoft. For this one I would once again recommend to get an account for the different parts of the Power Platform (Power Apps, Power Automate, Power BI, Power Virtual Agents).
As I had worked with Power BI before, I focused on the other three parts mainly for this exam. I would say that Power Apps is the most important of these for the exam, but I would encourage you to play around with all of them, it is quite fun as well after all!
