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 deploying a new Azure SQL Database that will store Personally Identifiable Information (PII). You need to ensure that the data is encrypted at rest and that access to encryption keys is logged. Which THREE actions should you take? (Choose three.)

Question 1hardmulti select

Full question →

A
Use Always Encrypted to encrypt all PII columns.
Why wrong: Always Encrypted encrypts specific columns, not the entire database; TDE is required for full at-rest encryption.
B
Grant the managed identity of the database access to the key vault with 'get', 'wrapKey', and 'unwrapKey' permissions.
This is necessary for TDE with CMK to access the encryption key.
C
Configure TDE with service-managed keys.
Why wrong: Service-managed keys do not allow logging of key access because Microsoft manages the keys.
D
Enable Transparent Data Encryption (TDE) with customer-managed keys in Azure Key Vault.
TDE with CMK encrypts the database at rest and allows logging key access via Key Vault audit logs.
E
Enable auditing on the Azure Key Vault to log key operations.
Key Vault auditing logs all access to keys, including get, wrap, and unwrap operations.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Grant the managed identity of the database access to the key vault with 'get', 'wrapKey', and 'unwrapKey' permissions.

Option B is correct because to use customer-managed TDE keys stored in Azure Key Vault, the Azure SQL Database's managed identity must be granted 'get', 'wrapKey', and 'unwrapKey' permissions. This allows the database to access the key for encryption and decryption operations while maintaining a secure, auditable key management chain.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse Always Encrypted with TDE, selecting Always Encrypted for at-rest encryption when it is actually designed for client-side encryption of sensitive columns, not for full database-level encryption at rest.

Detailed technical explanation

How to think about this question

TDE with customer-managed keys uses an asymmetric key stored in Azure Key Vault, which is protected by the vault's access policies and soft-delete/purge protection. The database engine uses the managed identity to authenticate to Key Vault and perform wrap/unwrap operations on the key, ensuring that the key never leaves the vault unencrypted. Auditing Key Vault logs all key operations, including get, wrap, and unwrap, providing a complete audit trail for compliance.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.

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.
