This lecture covers AWS storage volumes, focusing on EBS volumes. It explains the types of EBS volumes, their characteristics, and how to manage them using the AWS Management Console. The lecture also demonstrates creating and attaching EBS volumes to EC2 instances, highlighting the importance of availability zones and volume types. Key differences in pricing, performance, and availability among EBS volume types are discussed, along with the process of taking snapshots and modifying volume types.

What is the default root volume type created when launching an EC2 instance?

• S3 Bucket

• Elastic Block Store (EBS)

• Glacier

How does AWS ensure high availability of EBS volumes?

• By storing data in multiple regions

• By replicating data within the same availability zone

• By using magnetic storage

• By providing manual backup options

What is the first step in creating an additional EBS volume in the AWS Management Console?

• Attach the volume

• Click on 'Create Volume'

• Select the instance

• Choose the volume type

Which command is used to check the attached volumes on an EC2 instance?

• lsblk

• mount

• fdisk -l

• df -h

What must be ensured when creating an EBS volume in terms of availability zone?

• It should be in a different region

• It should be in the same availability zone as the instance

• It should be in a different availability zone

• It should be in the default region
