Microsoft Provided Exam Ready Zone Episodes
Preparing for the PL-300 certification involves mastering four key components: preparing the data, modeling the data, visualizing, and analyzing the data, and deploying and maintaining assets.
In the first step, preparing the data, one needs to acquire and clean data, making it ready for modeling and analysis. In the second step, modeling the data, one needs to develop a data model that is suitable for the analysis and reporting requirements. In the third step, visualizing and analyzing the data, one needs to create visualizations and perform analysis to uncover insights from the data. Finally, in the fourth step, deploying and maintaining assets, one needs to deploy the data model and visualizations in a production environment and ensure their performance and security.
Microsoft offers a series of Exam Ready Zone episodes to help you prepare:
Preparing for PL-300 – Prepare the Data (1 of 4)
