You have an Azure subscription and you want to view which security settings are applied to the subscription by default. Which Azure policy or initiative definition should you review?

The "Enable Monitoring in Azure Security Center" initiative definition is correct because it's a built-in Azure Policy initiative specifically designed to deploy and configure the default security monitoring settings for Azure Security Center (now Microsoft Defender for Cloud). This initiative ensures that resources within the subscription are onboarded to Defender for Cloud and have essential security features enabled. The "Audit diagnostic setting policy definition" is incorrect as it focuses on auditing diagnostic settings for resources, not the overall security monitoring configuration. The "Enable Azure Monitor for VMs initiative definition" is incorrect because it's specific to enabling monitoring for virtual machines using Azure Monitor, not the broader security posture managed by Defender for Cloud. The "Azure Monitor solution 'Security and Audit' must be deployed policy definition" is incorrect because while related to security, it refers to a specific legacy Azure Monitor solution rather than the comprehensive default settings managed by the "Enable Monitoring in Azure Security Center" initiative.
