How CertGrid questions are reviewed

Every bank is written and maintained by our team against the vendor's current skills outline - not copied or scraped from exam content. Each question is mapped to a published concept, every answer carries an explanation covering why the right option is right and why each wrong option is wrong, and banks are re-reviewed whenever the exam changes. Individual exam pages show the date each bank was last reviewed.

Frequently asked questions

Are these official Microsoft exam questions?

No. CertGrid is an independent practice platform. We do not provide real or leaked exam questions. Our questions are original and designed to help you practice the concepts, scenarios, and difficulty style of Microsoft certification exams.

Which Microsoft exams are covered?

Azure role-based exams (AZ-900, AZ-104, AZ-204, AZ-305, AZ-500, AZ-700 and more), Microsoft 365 (MS-102), Security, Compliance & Identity (SC-900, SC-100, SC-200, SC-300), Azure AI and Data (AI-900, DP-series), and endpoint/modern-work exams. See the full list below.

Is it free to practice?

Yes. Free users get a fixed set of 20 practice questions for each exam, retryable anytime, with basic explanations. A Pro plan unlocks the full question bank, complete explanations, and full-length timed mock exams across every Microsoft bank.

Are the questions kept up to date?

Yes. Each bank is reviewed against the current Microsoft skills outline and updated as Microsoft revises the exam. Individual exam pages show when the bank was last reviewed.

Do Microsoft certifications expire?

Yes. Most Microsoft role-based certifications (Associate and Expert level) are valid for one year, and you renew for free by passing a short online assessment on Microsoft Learn before the expiration date rather than retaking the full exam.

How much do Microsoft certification exams cost?

Fundamentals exams like AZ-900, SC-900 and AI-900 are about $99 USD, while Associate and Expert role-based exams such as AZ-104, AZ-305 and SC-100 are about $165 USD, though Microsoft occasionally runs free voucher promotions.
