Cloud Storage also supports event notifications, enabling integration with services like Dataflow, Cloud Functions, and AI/ML pipelines for automated processing. Its high durability, availability, and low-latency access make it ideal for storing backups, media assets, and other unstructured datasets at enterprise scale.
D Firestore is a NoSQL document database optimized for real-time applications with structured document data. While it supports rapid updates, offline synchronization, and low-latency access for application data, it is not designed for storing large unstructured objects like media files or backups.
Question 160
Which Google Cloud service provides centralized security management and risk assessment across cloud resources with compliance monitoring?
A) Cloud Logging
B) Cloud Monitoring
C) Cloud Security Command Center
D) Cloud IAM
Answer: C
Explanation:
A Cloud Logging collects and stores logs from applications, services, and infrastructure, providing insights into events, errors, and operational activities. While essential for observability and troubleshooting, Cloud Logging does not provide centralized security management, vulnerability detection, risk assessment, or compliance monitoring. Its focus is on capturing and analyzing log data rather than managing organizational security posture.
B Cloud Monitoring tracks metrics, uptime, system performance, and operational health across Google Cloud resources. It enables dashboards, alerting, and trend analysis to maintain reliability. However, Cloud Monitoring is not designed for centralized security governance, risk assessment, or compliance monitoring. Its primary function is operational observability rather than proactive security management.
C Cloud Security Command Center (Cloud SCC) is the correct answer because it provides a centralized, comprehensive security management platform for Google Cloud. Cloud SCC continuously monitors cloud resources, identifies misconfigurations, detects vulnerabilities, and integrates threat intelligence to generate actionable alerts. It supports compliance monitoring for standards such as HIPAA, GDPR, and PCI DSS, helping organizations maintain regulatory alignment. Cloud SCC also leverages dashboards and integration with Cloud Logging and Cloud Monitoring to provide visibility and observability across the environment. Organizations can prioritize risks, investigate incidents, enforce security policies, and implement automated remediation, reducing operational risk and strengthening overall cloud security posture. Cloud SCC enables proactive security management and centralized oversight across multiple projects, networks, and services.
D Cloud IAM (Identity and Access Management) manages user identities and resource access permissions, enforcing least-privilege access policies across Google Cloud resources. While critical for access control, IAM does not provide vulnerability detection, risk assessment, or compliance monitoring. Its role is limited to identity-based access governance rather than holistic security management.
