An organization must identify and fix security vulnerabilities in its cloud infrastructure and applications. Which Google Cloud service should they use?

Security Command Center is Google Cloud's unified security posture management and threat detection service that identifies vulnerabilities, misconfigurations, and active threats across cloud resources and applications. It provides a centralized dashboard with prioritized security findings and actionable remediation recommendations, making it the correct tool for identifying and fixing security vulnerabilities across a cloud environment.

Google Cloud Armor provides DDoS protection and web application firewall capabilities for external-facing applications but does not perform broad vulnerability scanning or security posture assessment across cloud infrastructure.

Cloud Storage is an object storage service for storing and retrieving unstructured data and has no security vulnerability scanning or assessment capabilities.

VPC networks provide network isolation and connectivity for cloud resources but are a networking construct, not a security vulnerability identification or remediation service.
