NEW QUESTION # 64
You have an Azure virtual machine named Server1 that runs Windows Server 2022. Server! contains an instance of Microsoft SQL Server 2022 named SQL1 and a database named DB1.
You create a master key in the master database of SQL1.
You need to create an encrypted backup of DB1.
What should you do?
Answer: A
Explanation:
Basic Concept: This question tests high availability and disaster recovery design for Azure SQL, SQL Server on Azure VMs, and regional failure scenarios.
Why D is Correct: Create a certificate in the master database of SQLl. is correct because it is the feature whose normal purpose matches the stated requirement. Certificates support encryption and authentication, but the correct certificate-related object depends on whether the task is TLS, Always Encrypted, or user authentication. The scenario wording points to that specific behavior: You need to create an encrypted backup of DB1.
Why A is Wrong: Create a symmetric key in DB1. is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It protects or manages a different security layer, so the required database access or protection behavior would still be incomplete.
Why B is Wrong: Enable visualization-based security (VBS) on Server1. is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It is not the right enforcement point for this case; the scenario needs the control that governs the data or identity path being tested.
Why C is Wrong: Certificates support encryption and authentication, but the correct certificate-related object depends on whether the task is TLS, Always Encrypted, or user authentication. It does not satisfy the required identity, encryption, firewall, auditing, or data-exposure boundary described in the scenario: You need to create an encrypted backup of DB1.
