Question

Which of the following AWS features or services can be used to provide root storage volumes for Amazon EC2 instances?

1) Amazon S3
2) Amazon EBS
3) Amazon RDS
4) Amazon DynamoDB

Answer 1

The correct answer is Amazon EBS. Amazon EBS is a cloud-based storage service provided by AWS that allows you to create persistent block storage volumes and attach them to Amazon EC2 instances.

Step-by-step explanation:

The correct answer is Amazon EBS. Amazon EBS (Elastic Block Store) is a cloud-based storage service provided by Amazon Web Services (AWS) that allows you to create persistent block storage volumes and attach them to Amazon EC2 instances. These volumes provide root storage for your EC2 instances, allowing you to store and manage data.

Amazon S3 is a separate storage service offered by AWS that is commonly used for storing and retrieving large amounts of unstructured data, such as images, videos, and backups, but it cannot be used for root storage of EC2 instances.

Amazon RDS (Relational Database Service) and Amazon DynamoDB are database services provided by AWS and are not intended for providing root storage volumes for EC2 instances.

Answer 2

Amazon EBS (Elastic Block Store) (Option 2) can be used to provide root storage volumes for Amazon EC2 instances.

Step-by-step explanation:

Amazon EBS is a block storage service designed to be used with Amazon EC2 instances. It provides highly available and reliable storage volumes that can be attached to EC2 instances as root volumes. These volumes act like raw, unformatted block devices and can be used for installing an operating system or storing application data. In contrast, Amazon S3 (Option 1) is an object storage service, Amazon RDS (Option 3) is a managed relational database service, and Amazon DynamoDB (Option 4) is a NoSQL database service. These services are not typically used for providing root storage volumes for EC2 instances.

Option 2 is the answer.
