A) Cloud Pub/Sub
B) Cloud Functions
C) Cloud Dataflow
D) Cloud Scheduler

Answer: A) Cloud Pub/Sub

Explanation:

Cloud Pub/Sub is Google Cloud’s fully managed messaging and event ingestion service designed for real-time communication between applications and services. It follows a publish-subscribe model, where publishers send messages to topics and subscribers receive them, decoupling components and enabling scalable, distributed, event-driven architectures. Cloud Pub/Sub ensures reliable message delivery, automatic retries, and at-least-once delivery guarantees, making it suitable for critical systems and high-throughput workloads.

It supports millions of messages per second globally while maintaining low latency. Cloud Pub/Sub integrates seamlessly with other Google Cloud services, including Dataflow for streaming analytics, Cloud Functions for event-driven workflows, BigQuery for analytics, and Cloud Storage for storage-based triggers. Security is enforced through IAM roles, encryption at rest and in transit, and audit logging, ensuring compliance and data protection.

Operationally, Cloud Pub/Sub eliminates the need for custom messaging infrastructure, allowing developers to focus on application logic rather than message delivery and scaling. Features like message ordering, filtering, and dead-letter topics provide flexibility for complex workflows. Real-world use cases include IoT telemetry ingestion, real-time analytics dashboards, triggering serverless functions, and orchestrating microservices communication.

Strategically, Cloud Pub/Sub empowers enterprises to build agile, event-driven, and scalable systems. Its managed, globally distributed, and fault-tolerant architecture ensures reliable event delivery, accelerates data-driven decision-making, and supports modern cloud-native application development without operational overhead.

Question 179

Which Google Cloud service provides identity and access management for users, groups, and resources?

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 access to cloud resources. IAM allows organizations to define who can access specific resources and the actions they can perform, enforcing security policies consistently across all services. It supports role-based access control (RBAC), predefined roles, and custom roles to accommodate diverse organizational needs.

IAM integrates with Cloud Identity, Cloud KMS, Apigee, and other Google Cloud services, providing uniform access control and governance. Security features include audit logging, conditional access, and multi-factor authentication support. Operationally, IAM simplifies administration, reduces risk by enforcing least-privilege principles, and supports automated identity and permission management.

Real-world use cases include granting developers access to specific projects, managing service accounts, securing sensitive datasets in BigQuery, and controlling production environment access. Compliance with GDPR, HIPAA, and PCI DSS is supported via detailed logs, audit trails, and access tracking.

Strategically, Cloud IAM enables enterprises to secure cloud resources, implement governance frameworks, and streamline operational access management. Centralized control over permissions reduces security risks, ensures compliance, and supports scalable cloud adoption, forming a foundational component for secure, enterprise-grade operations in Google Cloud.
