Which service in Azure can be used to ensure data residency requirements are met?
A. Incorrect: It is a service for transferring large amounts of data to and from Azure, but it does not enforce regional restrictions.
B. Correct: Azure Policy allows you to define and enforce policies that restrict resources from being created outside of specific regions, thereby ensuring data residency requirements are met.
C. Incorrect: Although Azure SQL Database can be deployed in different regions for compliance reasons, it does not provide the policy enforcement capabilities needed to ensure data residency.

AZ-900 is usually the broad Microsoft cloud entry point when you need cloud credibility before moving into administration, engineering, or architecture.
- Role examples: cloud support specialist, junior cloud administrator, technical account manager, and solution consultant.
- Where it shows up: cloud fundamentals, platform operations, customer-facing cloud work, and internal IT modernization.
- On-the-job payoff: you need Azure service language, pricing basics, governance basics, and cloud tradeoff awareness.
- Typical next step: Often feeds into AZ-104 for administration or AZ-305 for architecture.
AZ-900 is a cloud language exam first. It rewards service-family recognition, pricing and governance basics, and knowing which Azure category the question is really pointing at.
- Current emphasis in this bank: Describe Azure architecture and services (42%).
- A lot of misses come from chasing one familiar service name instead of matching the scenario to the right cloud concept: pricing, identity, storage, networking, or governance.
- Best official starting point: Microsoft Certified: Azure Fundamentals.
The fastest path is to turn this exam into a repeatable pattern-recognition loop instead of a one-time cram session.
- Start with the free daily set closed-book so you can see which parts of the cloud and it lane still feel weak.
- Use every explanation as a checkpoint for why the right answer fits the scenario and why the other answer choices do not.
- Open the official Microsoft source when a concept keeps missing so you fix the gap at the source instead of rereading generic notes.
- Use the nearby cert pages when you need broader context around the same job path or technology stack.
The usual misses happen when learners recognize keywords but do not slow down enough to match the scenario to the exact decision the exam is testing.
- Reading for one familiar keyword and skipping the deeper clue that tells you which cloud and it concept actually fits.
- Memorizing isolated terms without checking why the right answer wins over the other answer choices in the same scenario.
- Ignoring the official Microsoft source after a miss and hoping the next question will feel easier on its own.
- Studying this page in isolation when one nearby cert page could clear up the broader pattern much faster.
The fastest path is simple: answer the set, review the reasoning, then use the score history and source links to decide what to hit next.
- Answer the free set first without looking anything up so the score reflects what is actually sticking.
- Read every explanation, especially the wrong answer choices, so the weaker options stop looking plausible next time.
- Open the linked source when a concept feels weak, then come back and repeat the question flow while the wording is fresh.
- Use the 7-day score keeper, related cert links, and comparison pages to decide what to study next instead of guessing.
- Move into the app when you want the full bank, timed reps, readiness tracking, and a steadier mobile study loop.
Use these official Microsoft resources alongside the daily practice set. They cover the provider's own exam page, study guide, or prep material.

How are AZ-900 questions generated?
dotCreds builds AZ-900 practice questions from Microsoft Learn documentation and product references, with official or primary sources preferred first. The questions are written for realistic study practice, not copied from exam dumps.
How are explanations sourced?
Each question includes a source-backed explanation and a link to the documentation or reference used to validate the answer. If an official page is too broad, dotCreds uses a reputable answer-level reference instead of pretending a generic page proves the answer.
What score do I get?
The page tracks today's answered count and accuracy for the 10-question daily set, then saves a 7-day score history on this device so you can see your recent practice trend.
Why use this site?
The site is the fastest way to start AZ-900 practice without installing anything. It is built for daily recall, quick weak-topic discovery, and source-backed explanations you can review immediately.
Why use the app when available?
The web page is the quick free sampler. If a dotCreds app is available for AZ-900, the app is better for larger banks, focused weak-domain drills, longer review sessions, and mobile study routines.
