CLF-C02 Cloud Concepts & AWS Core Services

Question 1

What is the primary benefit of cloud computing?

Accepted Answer

On-demand resource availability and cost savings

Answer

The primary benefit of cloud computing is its ability to provide on-demand access to computing resources, such as servers, storage, and databases, over the internet. This eliminates the need for organizations to purchase and maintain their own physical infrastructure, leading to significant cost savings. Users only pay for the resources they consume, allowing for greater flexibility, scalability, and efficiency compared to traditional IT setups.

Question 2

Which AWS service is used to store and retrieve any amount of data at any time?

Accepted Answer

Amazon S3

Answer

Amazon S3 (Simple Storage Service) is the AWS service specifically designed for storing and retrieving any amount of data from anywhere on the web. It is an object storage service known for its scalability, data availability, security, and performance. S3 is commonly used for backups, data archiving, content distribution, and hosting static websites, making it a versatile solution for various data storage needs.

Question 3

Which AWS service provides virtual servers?

Accepted Answer

Amazon EC2

Answer

Amazon EC2 (Elastic Compute Cloud) is the AWS service that provides resizable compute capacity in the cloud, essentially offering virtual servers. Users can launch and configure virtual machines (instances) with various operating systems and software, scaling them up or down as needed. EC2 is fundamental for running applications, websites, and performing computational tasks without the need for physical hardware.

Question 4

Which pricing model allows you to save money on AWS services based on long-term usage?

Accepted Answer

Reserved Instances

Answer

Reserved Instances is an AWS pricing model that allows customers to save money on services by committing to a specific usage level for a 1-year or 3-year term. By reserving compute capacity in advance, users receive a significant discount compared to on-demand pricing. This model is ideal for applications with predictable and steady workloads, offering substantial cost optimization for long-term usage.

Question 5

What is the shared responsibility model in AWS?

Accepted Answer

AWS handles infrastructure, customer handles data and applications

Answer

The shared responsibility model in AWS defines the security responsibilities between AWS and the customer. AWS is responsible for the security *of* the cloud, meaning they secure the underlying infrastructure that runs all cloud services. Conversely, the customer is responsible for security *in* the cloud, which includes managing their data, applications, operating systems, network configuration, and access controls within their AWS environment.
