Answer: A) Cloud Logging

Explanation:

Cloud Logging is a fully managed service on Google Cloud that collects, stores, and analyzes logs from applications, infrastructure, and security events. It provides centralized observability, allowing organizations to monitor, troubleshoot, and audit their cloud environments efficiently. Logs can originate from Google Cloud services, virtual machines, containers, custom applications, or third-party sources, providing a unified platform for operational visibility.

Cloud Logging supports real-time log ingestion, filtering, querying, and exporting to BigQuery, Cloud Storage, or Pub/Sub for further analysis and reporting. Integration with Cloud Monitoring, Security Command Center, and Cloud Functions allows teams to correlate logs with metrics, incidents, and security events, enabling proactive monitoring and automated responses.

Operational benefits include centralized log management, automated alerting, and audit compliance. Cloud Logging reduces the complexity of managing disparate logging systems and ensures that operational, performance, and security data is available for analysis when needed. Real-world use cases include debugging applications, tracking API usage, auditing security events, monitoring infrastructure performance, and implementing compliance reporting.

Strategically, Cloud Logging empowers organizations to improve operational reliability, maintain visibility across cloud workloads, and support security and compliance initiatives. By centralizing logs in a managed platform, enterprises can make data-driven decisions, detect anomalies proactively, and maintain control over their cloud environments. It supports scalable, secure, and efficient observability essential for modern cloud-native operations.

Question 120

Which Google Cloud service provides identity and access management to control who can access cloud resources and what actions they can perform?

A) Cloud Identity
B) Cloud IAM
C) Cloud KMS
D) Apigee

Answer: B) Cloud IAM

Explanation:

Cloud Identity and Access Management (IAM) is Google Cloud’s centralized platform for managing user, group, and service account access across cloud resources. IAM enables organizations to define granular access policies, specifying who can perform which actions on specific resources. It supports predefined roles, custom roles, and role-based access control (RBAC), allowing enterprises to implement the principle of least privilege effectively and securely manage access across projects, services, and data stores.

IAM integrates with Cloud Identity, Cloud KMS, Apigee, and other Google Cloud services, ensuring consistent enforcement of access policies across the entire environment. Security features include multi-factor authentication, conditional access, audit logging, and integration with the Security Command Center for continuous compliance monitoring.

Operationally, IAM simplifies access management by centralizing control, automating role assignments, and providing detailed audit logs for security and compliance purposes. Real-world use cases include granting developers access to development or staging projects, managing production system permissions, controlling access to sensitive datasets in BigQuery, and managing service accounts for automated workflows. IAM helps enforce regulatory compliance with standards such as GDPR, HIPAA, and PCI DSS.

Strategically, Cloud IAM enables organizations to secure cloud resources, reduce operational risk, and maintain governance frameworks. By providing centralized, scalable, and auditable access control, IAM supports enterprise-scale cloud adoption, strengthens security posture, and ensures that organizational policies are consistently enforced across all cloud services. It forms a foundational component for secure, enterprise-grade operations, enabling organizations to confidently manage access and protect critical digital assets in the cloud.
