Question 1: Which of the following is NOT a key characteristic of cloud computing?

(a) On-demand self-service

(b) Broad network access

(c) Fixed resource allocation

(d) Resource pooling

Answer: (c) Fixed resource allocation. Cloud computing is characterized by the ability to dynamically allocate and deallocate resources as needed, unlike traditional IT where resources are often fixed.

Question 2: What is the difference between IaaS, PaaS, and SaaS?

(a) They are all the same.

(b) IaaS provides infrastructure, PaaS provides a platform, and SaaS provides software.

(c) IaaS provides software, PaaS provides a platform, and SaaS provides infrastructure.

(d) IaaS provides a platform, PaaS provides software, and SaaS provides infrastructure.

Answer: (b) IaaS provides infrastructure, PaaS provides a platform, and SaaS provides software. IaaS (Infrastructure as a Service) provides virtual machines, storage, and networking; PaaS (Platform as a Service) provides development and deployment environments; SaaS (Software as a Service) provides ready-to-use software applications.

Question 3: What is a virtual machine (VM)?

(a) A physical computer

(b) A software emulation of a physical computer

(c) A type of cloud storage

(d) A network protocol

Answer: (b) A software emulation of a physical computer. VMs allow multiple operating systems to run concurrently on a single physical server, improving resource utilization and flexibility.

Question 4: Which cloud deployment model involves sharing resources among multiple organizations?

(a) Public cloud

(b) Private cloud

(c) Hybrid cloud

(d) Community cloud

Answer: (d) Community cloud. A community cloud is shared by several organizations with common concerns, such as a group of government agencies or a consortium of businesses.

Question 5: What is the purpose of a load balancer in a cloud environment?

(a) To store data

(b) To distribute network traffic across multiple servers

(c) To manage virtual machines

(d) To encrypt data

Answer: (b) To distribute network traffic across multiple servers. Load balancers ensure high availability and prevent server overload by distributing incoming requests evenly.

Question 6: What is cloud bursting?

(a) The process of migrating data to a different cloud provider

(b) The ability to quickly scale resources up or down based on demand

(c) A type of security vulnerability

(d) A method for encrypting data in the cloud

Answer: (b) The ability to quickly scale resources up or down based on demand. Cloud bursting allows applications to seamlessly scale to handle peak loads by leveraging additional resources from a public cloud.

Question 7: What is a key concern related to data security in the cloud?

(a) Server maintenance

(b) Network latency

(c) Data breaches and unauthorized access

(d) Software updates

Answer: (c) Data breaches and unauthorized access. Protecting sensitive data from unauthorized access is a paramount concern when using cloud services.

Question 8: What is serverless computing?

(a) Running applications without servers

(b) Running applications on a single, dedicated server

(c) A type of cloud storage

(d) A method for reducing network latency

Answer: (a) Running applications without servers. Serverless computing abstracts away the management of servers, allowing developers to focus on code.

Question 9: What does API stand for in the context of cloud computing?

(a) Application Programming Interface

(b) Advanced Programming Interface

(c) Application Process Interface

(d) Advanced Process Interface

Answer: (a) Application Programming Interface. APIs provide a way for different software systems to communicate and interact with each other.

Question 10: Which protocol is commonly used for secure communication in the cloud?

(a) HTTP

(b) FTP

(c) HTTPS

(d) SMTP

Answer: (c) HTTPS. HTTPS uses SSL/TLS encryption to secure communication between clients and servers.

This quiz provides a brief overview of key concepts in cloud computing. For a more in-depth understanding, consider exploring online courses, certifications, and industry publications. The ever-evolving nature of cloud technology necessitates continuous learning to stay abreast of the latest advancements and best practices.
