Your subscription contains an Azure SQL server SQL1 with a database DB1. To run a vulnerability assessment for DB1 using Microsoft Defender for Cloud, what must you do first?

To run a vulnerability assessment for DB1 using Microsoft Defender for Cloud, you must first enable the Microsoft Defender for SQL plan. This plan provides the necessary capabilities, including vulnerability assessment and advanced threat protection for your Azure SQL databases. Without this plan enabled, the vulnerability assessment features will not be available. "From Advanced Threat Protection types, select SQL injection vulnerability" is incorrect because SQL injection vulnerability is a specific finding, not a prerequisite for enabling the assessment itself. "Configure the Send scan report to setting" and "Set Periodic recurring scans to ON" are configuration options after the Defender for SQL plan is enabled, not prerequisites for initiating the service.
