✍️ Sample IAB Questions & Answers
1. What is the role of a Mobile Measurement Partner (MMP)?
MMPs (such as AppsFlyer, Adjust, or Branch) provide independent, neutral attribution data that tracks which marketing channels drove installs and user actions across mobile campaigns.
2. What is 'skippable' vs 'non-skippable' video advertising?
Skippable video ads (like YouTube TrueView) let viewers skip after typically 5 seconds, while non-skippable ads must be viewed entirely before the content begins.
3. What does 'purpose limitation' mean in data privacy?
Purpose limitation is a GDPR principle that requires personal data to be collected for specific, explicit, and legitimate purposes and not further processed in incompatible ways.
4. What is a mid-roll video ad?
Mid-roll ads are video advertisements inserted at a break point during longer-form video content, similar to a traditional TV commercial break, and tend to have high completion rates.
5. What is 'programmatic native advertising'?
Programmatic native advertising applies automated buying technology to native ad inventory, dynamically assembling ad components (headline, image, description) to fit each publisher's native format at scale.
6. What is 'branded content' and how does it differ from a traditional ad?
Branded content is storytelling-driven content created by or with a brand that aims to entertain, inform, or inspire, with brand values front and center—rather than leading with a direct product pitch.

- A fixed IAB question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
- Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
- A printable IAB cheat sheet you can print or save as a PDF.
