I sat for the Microsoft GH-500 exam four weeks ago. The syllabus covers describing GHAS security features and functionality, configuring and using secret scanning, configuring and using dependency management, configuring and using code scanning, using code scanning with CodeQL, describing GitHub Advanced Security best practices, and configuring GitHub Advanced Security tools in GitHub Enterprise. I started with the official Microsoft study guide but needed something faster that let me practice real questions. That's when I found ITExamsTopics.COM and grabbed their web version to work through alongside my notes.
What helped most was how the exam-style questions were framed on their platform - they showed how the real exam tests your understanding instead of just memorization. Since using code scanning with CodeQL makes up 20% of the test and describing best practices makes up 20%, I focused on those practice questions first. Then I worked through configuring code scanning at 15%, configuring dependency management at 15%, configuring secret scanning at 10%, describing GHAS features at 10%, and configuring tools in GitHub Enterprise at 10%. I went through multiple rounds of real exam questions and sample questions before my exam date. If you're prepping for GH-500, try their free demo first, then grab ITExamsTopics web version for actual exam questions.
