Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A global company must comply with data sovereignty laws that require customer data to be stored and processed within the country of origin. Which cloud concept should they evaluate?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Data residency
Option C is correct because data residency refers to the physical location where data is stored, which is critical for compliance with data sovereignty laws. Option A (Data encryption) protects data at rest and in transit but does not control location. Option B (Data sovereignty) is the concept that data is subject to the laws of the country where it is collected, but the question asks for the concept to evaluate, which is data residency. Option D (Data classification) categorizes data sensitivity but doesn't address location.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
