Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

The monitoring service that provides threat protection across all of your services, whether in Azure or on-premises, is Azure Security Center. This service offers a unified security management system that provides advanced threat protection, security posture management, and security recommendations to help safeguard both Azure resources and on-premises environments.

It goes beyond just monitoring by integrating seamlessly with various Azure services and implementing security best practices, making it an essential tool for organizations aiming to enhance their security efforts across multiple environments. This functionality is crucial for identifying vulnerabilities and protecting infrastructure, which is why it stands out in comparison to the other choices provided.

Azure Monitor, while a powerful service for tracking performance and health metrics within Azure, does not specifically focus on threat protection across diverse environments. Therefore, Azure Security Center is the most comprehensive option regarding security and threat management.
