Quick Answer
The answer is Get and Wrap Key. This is correct because when a developer’s application encrypts data using Always Encrypted with a column master key stored in Azure Key Vault, the application must first retrieve the key metadata via the Get permission, then use the Wrap Key operation to encrypt a new column encryption key; the Unwrap Key permission is only required for decryption, not encryption. On the Microsoft Azure Database Administrator Associate DP-300 exam, this distinction often appears as a trap where candidates mistakenly include Unwrap Key for encryption tasks, testing your precise understanding of key operations in the Always Encrypted workflow. A common memory tip is to remember that wrapping “wraps” a new key for encryption, while unwrapping “unwraps” it for decryption—so for encrypting data, you only need Get and Wrap.
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 have an Azure SQL Database with Always Encrypted enabled for sensitive columns. You need to grant a developer the ability to encrypt data using a column master key stored in Azure Key Vault. What permissions must be assigned to the developer's Microsoft Entra identity in the key vault?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "always"
Why it matters: Absolute qualifier. An answer using 'always' is only correct if there are genuinely no exceptions — absolute statements are often wrong in networking.
Get, Decrypt, and Unwrap Key.
Why wrong: Decrypt is not needed for encryption; wrap is needed.
Get, Wrap Key, and Unwrap Key.
Wrap Key is needed to encrypt, and Unwrap Key is needed to decrypt. Get is required to retrieve the key metadata.
Get and Decrypt.
Why wrong: Decrypt alone is insufficient; wrap/unwrap are required.
Get, Sign, and Verify.
Why wrong: Sign and Verify are not used for Always Encrypted key operations.

Correct answer & explanation
Get, Wrap Key, and Unwrap Key.
To encrypt data with Always Encrypted, the developer's application must be able to retrieve the column master key metadata (Get) and then use the key to encrypt a column encryption key. This requires the Wrap Key operation, which generates a new encrypted column encryption key. Unwrap Key is needed only for decryption, not encryption. Therefore, Get and Wrap Key are the minimum permissions for encryption, making Option B correct.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Get, Decrypt, and Unwrap Key.
Why it's wrong here
Decrypt is not needed for encryption; wrap is needed.
Get, Wrap Key, and Unwrap Key.
Why this is correct
Wrap Key is needed to encrypt, and Unwrap Key is needed to decrypt. Get is required to retrieve the key metadata.

Get, Sign, and Verify.
Why it's wrong here
Sign and Verify are not used for Always Encrypted key operations.
Common exam traps
The trap here is that candidates often confuse the permissions needed for encryption versus decryption, mistakenly thinking Decrypt or Unwrap Key are required for encrypting data, when in fact only Wrap Key is needed for encryption.
Detailed technical explanation
Always Encrypted uses a two-tier key hierarchy: a column master key (CMK) stored in Azure Key Vault protects column encryption keys (CEKs). When encrypting data, the client driver calls the key vault to wrap (encrypt) a new CEK using the CMK; this requires the Wrap Key permission. The Get permission is needed to retrieve the CMK metadata and public key. Unwrap Key is only invoked during decryption to unwrap the CEK. Azure Key Vault access policies are evaluated per operation, so granting only necessary operations follows the principle of least privilege.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
