AWS, JavaScript, React - Deploy Web Apps on the Cloud - Creating an Amazon Machine Image (AMI)

This video tutorial provides a hands-on guide to working with Amazon Machine Images (AMIs) in AWS. It covers the process of creating an AMI from an existing EC2 instance, launching a new instance from the AMI, and configuring security groups. The tutorial also explains how to terminate an instance to manage usage costs effectively. Key concepts include AMI components, instance deployment, and security group settings.

What is an AMI in AWS?

• A network configuration tool

• A storage service

• A template for launching EC2 instances

• A type of virtual machine

Which of the following is NOT included in an AMI?

• Operating system

• Network configuration

• Amazon Elastic Block Store snapshots

• Application server

What is the first step in creating an AMI from an existing instance?

• Select 'Create Image' from the Image and Templates menu

• Launch a new instance

• Configure the security group

• Delete the existing instance

What should you do after creating an AMI to ensure it is ready for use?

• Immediately launch a new instance

• Wait for the status to change to 'available'

• Delete the AMI

• Modify the AMI details

When launching a new instance from an AMI, what is a necessary step?

• Select an existing key pair

• Delete the old instance

• Create a new key pair

• Configure a new security group

Why might a newly launched instance not display the expected web page?

• The security group has incorrect port settings

• The AMI was not created correctly

• The instance is using too much memory

• The instance is not running

How can you resolve a security group issue with an instance?

• Reboot the instance

• Delete the instance

• Create a new AMI

• Change the security group to the correct one

What happens to the EBS volumes when an instance is terminated?

• They are copied to a new instance

• They are automatically deleted

• They are archived

• They remain attached to the terminated instance

Why is it important to terminate unused instances?

• To increase security

• To improve network performance

• To avoid unnecessary charges

• To free up storage space

What should you check after terminating an instance to ensure no additional charges?

• The instance is removed from the table

• The instance state is 'terminated'

• The security group is updated

• The associated EBS volume is deleted
