A. B. C. D.Answer - B.
The AWS Documentation mentions the following.
An Amazon Machine Image (AMI) provides the information required to launch an instance, which is a virtual server in the cloud.
You specify an AMI when you launch an instance, and you can launch as many instances from the AMI as you need.
You can also launch instances from as many different AMIs as you need.
For more information on Amazon Machine Images, please refer to the following link:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AMIs.htmlThe correct answer is B. AMI.
Amazon Machine Image (AMI) is a pre-configured virtual machine image that contains the necessary information to launch an EC2 instance, including the operating system, application server, and application code. AMIs are used as templates to create new EC2 instances that have the same configuration as the original instance from which the AMI was created.
When an EC2 instance is launched using an AMI, the instance is created with the same configuration as the original instance from which the AMI was created. This can include the operating system, software packages, libraries, and any other configuration settings that were applied to the original instance.
EBS volumes, EC2 snapshots, and EBS snapshots are related to storage in AWS, but they do not contain the necessary software configuration to launch an EC2 instance.
EBS volumes are block-level storage devices that can be attached to EC2 instances to provide additional storage capacity.
EC2 snapshots are point-in-time backups of an EC2 instance's data, including the operating system, applications, and data files. These snapshots can be used to restore an instance to a previous state or to create new instances with the same data.
EBS snapshots are similar to EC2 snapshots, but they are used to back up EBS volumes rather than EC2 instances.
In summary, an AMI is a template that contains the software configuration to launch an EC2 instance. It includes the operating system, application server, and application code, and is used to create new instances that have the same configuration as the original instance from which the AMI was created.
