Short Explanation
Residency is about the map pin for where your data sits at rest. Encryption keys matter for crypto control, but residency is the location story.
Full Explanation
Data residency emphasizes where Microsoft stores customer data at rest geographically for regulatory needs. When a sister-city partnership requires citizen records in a specific geography, a council member who thinks that only means customer-managed encryption keys is mixing location commitments with key-management controls. Residency is the map-pin story; CMK is a cryptography-control story.
Residency is not about where Microsoft Paint stores desktop wallpapers for kiosk PCs. It is not about which credit card brand pays the CSP invoice. It is not about which Teams background image staff must use on video calls.
Exam caveat: encryption and key options may coexist with residency offerings, but answering a geography question with only CMK misses the residency concept MS-900 targets. Operational check: document the tenant’s data residency commitment for citizen-record workloads and separately document whether the city also requires customer-managed keys for crypto control. In municipal Microsoft 365 fundamentals scenarios, always map the business need to the named capability, reject distractors that describe a different pillar, and verify the control in the admin portal before telling leadership the risk is closed.
