The trap here is that candidates assume higher-tier plans like E5 automatically include all compliance features, but data residency requires a specific add-on regardless of the base plan tier.
Detailed technical explanation
How to think about this question
The Data Residency add-on for Microsoft 365 E3 leverages Microsoft's 'Local Region' policy to pin data to specific EU datacenter regions (e.g., France, Germany, Netherlands). Under the hood, this add-on applies Azure Active Directory conditional access policies and data location tags that prevent data replication outside the chosen EU geography, even during failover scenarios. In a real-world audit, this add-on provides the contractual and technical assurance needed for GDPR compliance regarding data localization.

Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
