Most Asked AWS Interview Questions

 AWS Interview Questions

1. What is Amazon Web Services?

   AWS is a secure cloud services platform offering various services like computing power, database storage, and content delivery. Think of it as a collection of tools and services that help you run applications and store data on the internet.

2. What are the Main Components of AWS?

   The main parts of AWS include:

   • Amazon Cluster (computing power).
   • Storage and Databases (like S3 for storage).
   • Management and Security (tools to manage and secure your services).
   • Networks (connectivity tools), Analytics (data analysis tools).
   • Application Services (tools to build applications).
   • Implementation and Management (tools to deploy and manage services).

3. Explain what S3 is all about?

   Amazon S3 (Simple Storage Service) is a storage service for the internet. It helps developers store and retrieve any amount of data at any time. You can control who can access your data and what they can do with it (like read or write).

4. What is AMI?

   AMI (Amazon Machine Image) is like a blueprint for creating virtual servers (instances) in the cloud. It includes the operating system and applications you need.

5. What is the relationship between an instance and AMI?

   An AMI is a template for creating instances (virtual servers). When you launch an instance, you are creating a running server based on the AMI template.

6. What is an EIP?

   In the context of AWS, EIP usually stands for Elastic IP Address, which is a static IP address designed for dynamic cloud computing. (The provided answer refers to Ethereum Improvement Proposal, which is unrelated to AWS).

7. What is CloudFront?

   Amazon CloudFront is a content delivery network (CDN) that speeds up the delivery of your website's static and dynamic content, like HTML, CSS, JavaScript, and images, to users around the world.

8. What is the procedure to send a request to Amazon S3?

   You can send requests to Amazon S3 using the REST API or AWS SDK. These methods help you interact with S3 to store and retrieve data.

9. What are key-pairs in AWS?

   Key-pairs are used for securing access to your AWS instances. They consist of a public key (stored by AWS) and a private key (stored by you). They help prove your identity when accessing your instances.

10. What is SimpleDB?

    Amazon SimpleDB is a simple database service that lets you store and query data without worrying about the underlying infrastructure. It handles data management tasks for you.

11. Is the property of broadcast or multicast supported by Amazon VPC?

    AWS VPCs (Virtual Private Clouds) do not support multicast by default. However, AWS engineers have developed a solution to enable multicast within VPCs.

12. How many IP addresses are allowed for each account in AWS?

    When creating a VPC, you must specify an IP range. This range can be between 16 IP addresses (/28) and 65,536 IP addresses (/16). You can add more ranges if needed.

13. What is meant by Edge location?

    An edge location is a data center that serves cached content (like videos and images) to users in different locations worldwide. This helps reduce the time it takes to load content.

14. What is Snowball?

    AWS Snowball is a physical device that helps you transfer large amounts of data to and from AWS. It's useful when you have too much data to transfer over the internet quickly or securely.

15. What is a subnet?

    A subnet is a subdivision of your VPC's IP address range. Public subnets have a route to the internet, while private subnets do not. They help organize and secure your resources.

16. What is AWS CloudTrail?

    AWS CloudTrail is a service that logs all actions taken in your AWS account. It helps with governance, compliance, and auditing by recording what happened, when it happened, and who did it.
