AB-900 Prep: M365 Admin

The serious study companion for AB-900 (Microsoft 365 Copilot and Agent Administration Fundamentals). 500 original questions built to the official Study Guide, plus a full-length mock exam. One-time purchase, no subscription, fully offline.

■ 500 original questions, built to the official Study Guide
Authored to match the AB-900 blueprint across all 3 domains — never copied from Microsoft practice questions, docs, or admin-center screenshots. Three question types: single choice, multiple response, and matching.

■ Three-layer explanations: learn by understanding
- Per-option rationale (why each choice is right or wrong)
- An overall explanation for the question
- Source references (Microsoft Learn)
The role differences between easily-confused products — DLP vs sensitivity labels, Defender vs Purview — finally click. Build real knowledge instead of relying on elimination.

■ Full-length mock exam
Recreates the real exam (~45 minutes, pass mark 700/1000). After finishing, per-domain accuracy reveals your weak spots. Choose 5–50 questions.

■ Structured, efficient study
- Study by domain and section across all 3 domains (focus on the high-weight, tricky Purview domain)
- 5 study modes (sequential, shuffle, weak-spot focus, favorites, review, and more)
- Progress syncs across your devices via iCloud

■ Bilingual JA/EN to master the terminology
AB-900 can be taken in Japanese, but product and admin-center names (Microsoft Purview, Microsoft Entra ID, Defender XDR, etc.) are in English. Switch between Japanese and English to understand the material and lock in the English terms.
