AWS Associate General Knowledge and Prerequisites 1 — Questions and Answers
Question 1: Which of the following AWS services is used to manage and provision computing power in the cloud?
- Amazon RDS
- Amazon EC2 (Correct answer)
- Amazon S3
- Amazon VPC
Correct answer: Amazon EC2
Amazon EC2 (Elastic Compute Cloud) provides scalable computing capacity in the AWS cloud. It allows users to provision and manage virtual servers (instances) with various operating systems and hardware configurations, offering flexible and resizable compute resources for virtually any workload.
Question 2: What is the purpose of the AWS Shared Responsibility Model?
- To define the roles and responsibilities of AWS in terms of customer support
- To explain the responsibility of AWS for managing security and compliance in the cloud
- To outline the division of responsibilities between AWS and the customer regarding security (Correct answer)
- To define the cost-sharing model between AWS and the customer
Correct answer: To outline the division of responsibilities between AWS and the customer regarding security
The AWS Shared Responsibility Model defines what security tasks AWS manages ("security *of* the cloud") and what tasks the customer is responsible for ("security *in* the cloud"). This model clarifies the division of labor, ensuring customers understand their role in securing their data and applications while AWS secures the underlying infrastructure.
Question 3: Which AWS service would you use to ensure that your application can scale automatically based on changes in demand?
- Amazon CloudFront
- Amazon S3
- EC2 Auto Scaling (Correct answer)
- Amazon Route 53
Correct answer: EC2 Auto Scaling
EC2 Auto Scaling automatically adjusts the number of EC2 instances in your application based on demand, ensuring consistent performance and availability. It dynamically launches or terminates instances according to predefined policies, such as CPU utilization or network traffic, to efficiently handle fluctuating workloads without manual intervention.
Question 4: You want to set up a virtual network in AWS and control how resources communicate with each other. Which service would you use?
- Amazon VPC (Correct answer)
- Amazon EC2
- AWS CloudFormation
- AWS Elastic Beanstalk
Correct answer: Amazon VPC
Amazon VPC (Virtual Private Cloud) allows you to provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment, including IP address ranges, subnets, route tables, and network gateways, enabling secure and customized network configurations.
Question 5: Which AWS service is designed to provide a content delivery network (CDN) to distribute content globally with low latency?
- Amazon S3
- Amazon CloudFront (Correct answer)
- Amazon EC2
- AWS Direct Connect
Correct answer: Amazon CloudFront
Amazon CloudFront is a fast content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds. It caches content at edge locations worldwide, bringing it closer to users and reducing load on origin servers, thereby improving user experience.
