Explore the basics of cloud computing and how to launch your first EC2 instance using AWS. Learn about key concepts, service types, and the step-by-step process to get started with cloud infrastructure.
Which type of cloud model allows the general public to access and use resources managed by an external organization?
Explanation: Public cloud is available for use by the general public and managed by an organization offering cloud services. Private cloud is restricted to a single organization. Hybrid cloud combines both public and private elements. Personal cloud is not a standard cloud model.
Which cloud service model offers fundamental resources like virtual servers, networking, and storage?
Explanation: IaaS provides raw infrastructure components such as computing, networking, and storage. PaaS focuses on application development platforms. SaaS delivers completed software applications. NaaS is not commonly included among the three primary service models.
When creating an AWS account, which step is mandatory before you can start using cloud services?
Explanation: Providing payment details is required even for free accounts to verify identity. Selecting a server region, enabling multi-factor authentication, and adding team members are important but not mandatory at the initial sign-up step.
What is the main purpose of launching an EC2 instance in AWS using the management console?
Explanation: Launching an EC2 instance creates a virtual server for computing tasks. Creating a relational database is handled by other services. Setting up DNS and provisioning cloud storage are separate operations.
Which statement best describes cloud computing?
Explanation: Cloud computing provides scalable, on-demand access to computing and storage resources over the internet. Hosting on local servers, manual hardware provisioning, and exclusive use of physical devices do not reflect cloud computing's core benefits.
