For my supporters here, I'll be solving some questions here or giving detailed answers that I could not put on Udemy.
I've added a third practice test to the #GoogleCloud Digital Leader practice tests on Udemy. In this test, apart from further reinforcement of key topics, I've also covered lesser known topics that are important - support, launch stages, some migration terminologies and decisions, etc. If you're planning to take the certification, do all the tests - it will give you wide coverage of Google Cloud and also repeats of important areas. If you're fairly new to Google Cloud and don't have other professional certifications, I'd recommend that you start at least 45 days prior taking the first tests. Do a test partially, identify the topics that you are less familiar with, read up about them, then come back again for more questions.
Wish you the very best!
