The answer is the CREATE DATABASE permission on the logical server. This is the minimum permission needed to restore an Azure SQL database from backup without being able to delete the original, because a restore to a new database is technically a create operation—the user never touches the source database’s data or metadata. On the DP-300 exam, this question tests your understanding of the principle of least privilege in Azure SQL, and the common trap is choosing db_backupoperator or db_owner, which grant far too much control over the original database, or the SQL Server Contributor role, which is an Azure RBAC role that includes delete rights. Remember the key distinction: restoring to a new database is a CREATE, not a RESTORE operation in the permission sense. A simple memory tip is “Restore = Create New,” so only the CREATE DATABASE permission is required.
DP-300 Implement a secure environment Practice Question
This DP-300 practice question tests your understanding of implement a secure environment. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.
You are a database administrator for an Azure SQL Database. You need to allow a user to restore a database from a backup to a new database, but the user should not have permission to delete the original database. What is the minimum permission required?

Correct answer & explanation
✓
CREATE DATABASE permission on the logical server
The minimum permission required to restore a database from a backup to a new database in Azure SQL Database is the CREATE DATABASE permission on the logical server. This is because restoring a backup to a new database is essentially creating a new database, and the user does not need any additional permissions on the original database to perform this action. The db_backupoperator and db_owner roles grant excessive permissions on the original database, while the SQL Server Contributor role is an Azure RBAC role that provides broader management capabilities beyond what is needed.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
db_backupoperator database role
Why it's wrong here
db_backupoperator is not available in Azure SQL Database.
✗
db_owner database role
Why it's wrong here
db_owner includes full control over the database, including deletion, but also too broad for just restore.
✓
CREATE DATABASE permission on the logical server
Why this is correct
CREATE DATABASE permission allows restoring a backup as a new database without delete permissions.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.

✗
SQL Server Contributor role
Why it's wrong here
Contributor role includes delete permission and is more than needed.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume database-level roles like db_backupoperator are sufficient for restore operations, but in Azure SQL Database, restoring to a new database requires server-level CREATE DATABASE permission, not just backup-related roles.
Detailed technical explanation
How to think about this question
In Azure SQL Database, the CREATE DATABASE permission is a server-level permission that allows a user to create a new database, and restoring a backup to a new database is functionally equivalent to creating a new database from a backup source. This permission can be granted using the command 'GRANT CREATE DATABASE TO [user]' in the master database, and it does not imply any permissions on existing databases, thus satisfying the security requirement. A real-world scenario is when a DBA needs to delegate point-in-time restore capabilities to a support engineer without granting them access to delete production databases.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
