Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the E5 Security add-on with the E5 Compliance add-on, assuming security features cover compliance needs, but Microsoft separates these into distinct add-ons with different capabilities.
Detailed technical explanation
How to think about this question
Litigation hold in Exchange Online preserves all mailbox content, including deleted items and versions, indefinitely until released, which satisfies the regulation's requirement. The 7-year retention is implemented via a Microsoft Purview retention policy applied to Exchange mailboxes, which can be set to retain data for a specific period and then delete it. Automatic detection of passport numbers relies on built-in sensitive information types (e.g., 'Passport Number') in Microsoft Purview DLP, which can trigger auto-labeling with sensitivity labels; this requires the E5 Compliance add-on because E3 only supports manual or basic labeling without DLP auto-classification.
