Question 1 of 10
Objective 2.3
Design Data Storage Solutions
A database team is evaluating Azure SQL Database resources and wants to avoid relying on bundled DTU measurements to independently control compute, memory, and storage characteristics. Which purchasing model should they use?
The vCore purchasing model is designed to make compute, memory, and storage characteristics more transparent for Azure SQL Database sizing decisions. The vCore-based model fits when architects need clearer control over those resource dimensions. DTU bundles resources, elastic pools share resources across databases, and Premium Storage is not the SQL purchasing model being asked for.

Question 1 A database team is evaluating Azure SQL Database resources and wants to avoid relying on bundled DTU measurements to independently control compute, memory, and storage characteristics. Which purchasing model should they use?
Answer choices
- A. DTU-based model
- B. vCore-based model
- C. Elastic Pool model
- D. Premium Storage model
Correct answer
vCore-based model
The vCore purchasing model is designed to make compute, memory, and storage characteristics more transparent for Azure SQL Database sizing decisions. The vCore-based model fits when architects need clearer control over those resource dimensions. DTU bundles resources, elastic pools share resources across databases, and Premium Storage is not the SQL purchasing model being asked for.
Wrong-answer review
- A. DTU-based model: Bundled-capacity misconception: DTUs combine resource measures and are less granular for this sizing goal.
- C. Elastic Pool model: Shared-pool misconception: elastic pools are for groups of databases sharing capacity, not the purchasing model requested.
- D. Premium Storage model: Storage-tier misconception: Premium Storage is not the Azure SQL Database purchasing model in this scenario.

Where to go after the daily web set
How are AZ-305 questions generated?
dotCreds builds AZ-305 practice questions from public exam objectives and Microsoft Learn and exam-objective references. The questions are written for realistic study practice, not copied from exam dumps.
How are explanations sourced?
Each question includes an explanation and, when available, a source link back to the provider documentation or reference used to validate the answer. That keeps the practice tied to study material you can actually review.
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-305 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 daily practice layer. If a dotCreds app is available for AZ-305, the app is better for larger banks, focused weak-domain drills, longer review sessions, and mobile study routines.
