1. Which of the following best describes "Infrastructure as a Service" (IaaS)?
A. A service model where users can deploy and manage applications
B. A model providing raw computing resources, including virtual machines and storage
C. A platform offering hosted software applications
D. A cloud-based database service
Answer: b) A model providing raw computing resources, including virtual machines and storage
Rationale: IaaS provides the basic infrastructure services (e.g., computing power, storage,
networking) in a cloud environment.
2. What is the primary function of a Virtual Private Cloud (VPC)?
A. To host virtual machines and containers
B. To allow private networking within a public cloud
C. To automatically scale cloud applications
D. To store backup data in the cloud
Answer: b) To allow private networking within a public cloud
Rationale: A Virtual Private Cloud (VPC) is a private network within a public cloud that enables
users to isolate and secure their resources.
3. Which of the following is a key challenge in cloud architecture?
,A. Lack of scalable storage
B. Managing distributed systems and resources
C. Increased hardware costs
D. Lack of serverless computing options
Answer: b) Managing distributed systems and resources
Rationale: Managing distributed systems and ensuring coordination, consistency, and availability
across cloud resources is a key challenge in cloud architecture.
4. Which of the following services provides machine learning and artificial intelligence
capabilities in the cloud?
A. Google AI Platform
B. AWS SageMaker
C. Microsoft Azure Machine Learning
D. All of the above
Answer: d) All of the above
Rationale: Google AI Platform, AWS SageMaker, and Microsoft Azure Machine Learning all
offer cloud-based solutions for building and deploying machine learning models.
5. Which of the following is a common pattern for building scalable cloud applications?
A. Monolithic architecture
B. Microservices architecture
, C. Client-server architecture
D. Peer-to-peer architecture
Answer: b) Microservices architecture
Rationale: Microservices architecture allows for building scalable applications by breaking down
complex services into smaller, independent components that can scale independently.
6. What is a common use case for cloud-based storage?
A. High-performance computing
B. Data backup and recovery
C. Video rendering
D. Network traffic management
Answer: b) Data backup and recovery
Rationale: Cloud-based storage is commonly used for backup and disaster recovery, as it offers
scalable and reliable storage solutions.
