5.1. Exam Strategy and Time Management

AB-900 at a glance:

• 40–60 questions (typically around 45)
• 45 minutes
• Passing score: 700/1000
• Format: multiple choice, multiple response, some interactive/scenario-based items

Time management:

• Target 45–55 seconds per question
• Flag and return: if a question takes more than 90 seconds, flag it and move on — come back at the end
• Multiple response questions (select all that apply) take longer — budget 90 seconds for these
• Leave 5 minutes at the end to review flagged items

Question approach:

1. Read the question stem and identify the key requirement (what problem is being solved? what outcome is needed?)
2. Eliminate obviously wrong answers first
3. For "which tool / which admin center" questions: identify the object type → match to the admin center that owns it
4. For "which Purview tool" questions: ask — is this about preventing, detecting, investigating, or measuring?
5. Watch for absolutes: "always," "never," "only" are often traps

High-value areas to review last (highest exam weight):

1. Microsoft Purview tools — know what each one is for
2. Copilot data access model — Graph + permissions
3. Admin center ownership map — which tool for which task
4. Zero Trust principles — the three pillars
5. Conditional Access — conditions vs. controls
