Recently, I had the amazing experience of acing the Google Cloud Professional Cloud Architect Exam. It wasn't a cakewalk, but with thorough preparation, it can be within reach for you too! Now, let's delve into the exam format, key topics, and tips to help you conquer this challenge like a champion.
Exam Platform and Expectations:
- Split Screen: Get familiar with the two-sided platform. One side displays questions, while the other presents case studies (20-30% of the exam) that test your real-world application skills.
- 50-60 Questions: Multiple-choice and multiple-select questions await, demanding sharp focus for 2 hours.
My Top Tip: Don't get stuck on a question! Flag it and move on. You can revisit it later if time permits. This ensures you see all questions and maximize your scoring chances.
