The correct answer is that the server’s TDE protector is changed to a customer-managed key from Azure Key Vault. This PowerShell command, specifically `Set-AzSqlServerTransparentDataEncryptionProtector`, updates the server-level TDE protector to use a key stored in Azure Key Vault, enabling customer-managed key (CMK) support for all databases under that server. On the Microsoft Azure Database Administrator Associate DP-300 exam, this tests your understanding of the distinction between server-level TDE protector configuration and database-level encryption settings, a common trap where candidates confuse enabling TDE with switching the protector type. Remember that this command does not disable TDE, check key permissions, or target a single database—it only changes the key source at the server scope. A useful memory tip: “Protector at the server, not the database—Key Vault for CMK, not a toggle.”
DP-300 Configure and manage automation of tasks Practice Question
This DP-300 practice question tests your understanding of configure and manage automation of tasks. 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.
Refer to the exhibit. You run the above PowerShell command to set the Transparent Data Encryption (TDE) protector for an Azure SQL Database server. What is the result?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The server’s TDE protector is changed to a customer-managed key from Azure Key Vault.
Option B is correct. The command sets the TDE protector to an Azure Key Vault key, enabling customer-managed key (CMK) for TDE. Option A is wrong because the command does not disable TDE. Option C is wrong because it does not check key permissions. Option D is wrong because the command is for the server-level TDE protector, not for a specific database.
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.
✗
The command fails because the service principal does not have permissions to the key vault.
Why it's wrong here
The command may succeed if permissions are correct.
✗
Transparent Data Encryption is disabled.
Why it's wrong here
The command sets a new protector, does not disable TDE.
✗
The TDE protector for the database "mydb" is updated.
Why it's wrong here
The command affects the server, not a specific database.
✓
The server’s TDE protector is changed to a customer-managed key from Azure Key Vault.
Why this is correct
The command sets the protector to a key vault key.

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.
