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).
An Amazon Machine Image (AMI) is a pre-configured virtual machine image used to create an EC2 instance. It contains the necessary information to launch an EC2 instance, such as the operating system, application server, and any additional software required to run the instance.
An AMI provides a template for launching an EC2 instance, which includes the instance type, security groups, and storage volumes. By using an AMI, you can easily create an instance that is pre-configured to run specific software and applications.
In summary, an AMI is a template that contains the software configuration to launch an EC2 instance. Therefore, option B is the correct answer to the question.
Option A, EBS Volumes, is incorrect because EBS volumes are a type of storage that can be attached to an EC2 instance, but they do not contain the software configuration required to launch an instance.
Option C, EC2 Snapshot, is also incorrect because an EC2 Snapshot is a point-in-time copy of an EBS volume. It can be used to create a new EBS volume or restore an existing one, but it does not contain the software configuration required to launch an EC2 instance.
Option D, EBS Snapshot, is similar to option C and is incorrect for the same reasons.
