1. Basic AWS Concepts

Question 1: What is AWS?

Answer: AWS stands for Amazon Web Services. It’s a comprehensive cloud computing platform provided by Amazon that offers a variety of services, including computing power, storage, databases, machine learning, analytics, and more.

Question 2: What is S3?

Answer: Simple Storage Service (S3) is a scalable object storage service in AWS, designed to store and retrieve any amount of data from anywhere on the web.

Question 3: Explain EC2.

Answer: Elastic Compute Cloud (EC2) is a virtual server in AWS, allowing users to run applications and scale capacity easily. It’s like having your computer in the cloud.

2. Compute Services

Question 4: What is the difference between EC2 and Lambda?

Answer: EC2 provides virtual servers, while Lambda is a serverless computing service. With Lambda, you only pay for the compute time your code consumes.

Question 5: How do you choose the right EC2 instance type?

Answer: Consider factors like CPU, memory, storage, and network performance requirements. AWS provides instance types optimized for different use cases.

3. Networking

Question 6: Explain VPC.

Answer: Virtual Private Cloud (VPC) is a virtual network dedicated to your AWS account. It allows you to launch AWS resources in a defined virtual network.

Question 7: What is a subnet?

Answer: A subnet is a range of IP addresses in your VPC. It helps in organizing resources and controlling traffic between them.

4. Storage Services

Question 8: How is EBS different from S3?

Answer: Amazon Elastic Block Store (EBS) provides block-level storage for EC2 instances, while S3 is object storage for the web. EBS is commonly used for databases and file systems.

Question 9: What is the use of Amazon Glacier?

Answer: Amazon Glacier is a low-cost storage service for archiving and long-term backup. It’s suitable for data that is infrequently accessed.

5. Database Services

6. Security

Question 12: How can you secure data at rest in S3?

Answer: Use S3 bucket policies and access control lists (ACLs) to manage permissions, and enable server-side encryption using AWS Key Management Service (KMS).

Question 13: What is AWS IAM?

Answer: AWS Identity and Access Management (IAM) is a service that helps securely control access to AWS resources. It enables the creation and management of AWS users and groups.

7. Monitoring and Logging

Question 14: What is CloudWatch?

Answer: Amazon CloudWatch is a monitoring service that provides data and actionable insights for AWS resources. It collects and tracks metrics, monitors logs, and sets alarms.

Question 15: How can you troubleshoot performance issues in an application hosted on AWS?

Answer: Use CloudWatch for monitoring, AWS Config for resource inventory, and AWS CloudTrail for auditing. Utilize these services to identify and resolve performance bottlenecks.

8. Automation and Orchestration

Question 16: What is AWS Lambda?

Answer: AWS Lambda is a serverless computing service that lets you run your code without provisioning or managing servers. It automatically scales and manages the compute resources.

Question 17: Explain AWS CloudFormation.

Answer: AWS CloudFormation is a service that allows you to define and provision AWS infrastructure as code. It helps in automating the deployment and management of resources.

9. Application Integration

Question 18: What is Amazon Simple Queue Service (SQS)?

Answer: Amazon SQS is a managed service offering to enable message queuing. It helps separate and scale microservices, supporting smooth operations for interconnected systems and serverless applications.

Question 19: How does AWS Step Functions work?

Answer: AWS Step Functions serves as a serverless orchestrator, streamlining the arrangement of AWS services and functions. It helps easily organize and connect different parts of important business applications without any fuss.

10. Pricing

Question 20: How does AWS pricing work?

Answer: AWS uses a pay-as-you-go model, where you pay only for the resources you consume. Pricing varies based on the services used, region, and usage patterns.

Question 21: What is the AWS Free Tier?

Answer: The AWS Free Tier is a set of free, limited-use AWS resources available to new AWS customers for a specified period after signing up.

11. Disaster Recovery

Question 22: How can you implement disaster recovery in AWS?

Answer: Use services like Amazon S3 for data backup, create automated snapshots of EBS volumes, and utilize AWS Disaster Recovery services like AWS Backup and AWS Elastic Disaster Recovery.

Question 23: What is AWS Snowball?

Answer: AWS Snowball is a service that helps transfer large amounts of data into and out of AWS using physical storage appliances.

12. CDN and Content Delivery

Question 24: Explain Amazon CloudFront.

Answer: Amazon CloudFront is like a global delivery helper. It securely spreads out data, videos, apps, and APIs to users worldwide, ensuring everyone gets what they need quickly and safely.

Question 25: How can you optimize content delivery with CloudFront?
