20+ practice questions focused on Implement a secure environment — one of the most tested topics on the Microsoft Azure Database Administrator Associate DP-300 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Implement a secure environment PracticeYour company has a strict policy that Azure SQL Database backups must be encrypted with customer-managed keys stored in Azure Key Vault. You configure TDE with AKV integration. After a key rotation, you find that long-running queries start failing with encryption errors. What is the most likely cause?
Explanation: When TDE is configured with Azure Key Vault (AKV) integration, the database uses the current key version from AKV to encrypt and decrypt data. If the previous key version is disabled or deleted during a key rotation, any long-running queries that still rely on that specific key version for decryption will fail with encryption errors. The database cannot automatically fall back to the new key version for in-flight operations that started before the rotation.
Your Azure SQL Database is configured with Advanced Threat Protection (ATP). You receive an alert about a SQL injection attack. After investigation, you confirm the attack was blocked. However, you need to ensure that future similar attacks are automatically prevented without manual intervention. What should you configure?
Explanation: Configuring the Azure SQL Database firewall to automatically block the attacker's IP address provides a proactive, automated defense against future SQL injection attempts from the same source. Advanced Threat Protection (ATP) can be integrated with Azure Logic Apps or other automation to trigger a firewall rule update that denies traffic from the offending IP, thereby preventing manual intervention. This directly addresses the requirement for automatic prevention of similar attacks.
A developer reports that they cannot connect to an Azure SQL Database using Azure AD authentication. The developer is a member of an Azure AD group that has been granted db_datareader role in the database. The connection string uses Active Directory Password authentication. What is the most likely issue?
Explanation: The most likely issue is that the Microsoft Entra ID group has not been created as a database user in the SQL Database. Even though the group has been granted the db_datareader role at the Microsoft Entra ID level, Azure SQL Database requires that the group be explicitly mapped to a database user via the CREATE USER [group name] FROM EXTERNAL PROVIDER statement. Without this mapping, the group's membership does not translate into database-level permissions, and the developer's authentication will fail.
You need to ensure that all connections to an Azure SQL Database are encrypted. Which setting should you enforce?
Explanation: Setting 'Force encryption' to 'Yes' on the Azure SQL Database server enforces TLS encryption for all client connections. This setting ensures that any client connecting to the database must use an encrypted connection, rejecting any unencrypted attempts. It is the direct mechanism to mandate encryption in transit, as opposed to encryption at rest or auditing.
You are deploying an Azure SQL Database that will store sensitive customer data. Compliance requirements dictate that the data must be encrypted at rest using a customer-managed key that is rotated every 90 days. You configure TDE with Azure Key Vault. What additional step is critical to ensure data remains accessible after key rotation?
Explanation: When using TDE with Azure Key Vault and customer-managed keys, the database is encrypted using a Data Encryption Key (DEK) that is protected by the key in Key Vault. Key rotation creates a new key version, but the DEK remains encrypted with the previous key version. To decrypt the DEK and access the data after rotation, the previous key version must remain enabled in Key Vault. If it is disabled or deleted, the database becomes inaccessible.
