What does AMI stand for?
A
AMI stands for Amazon Machine Image.
An Amazon Machine Image (AMI) is a template that contains a software configuration (for exam-ple, an operating system, an application server, and applications).
From an AMI, you launch an in-stance, which is a copy of the AMI running as a virtual server in the cloud. You can launch multiple instances of an AMI, as shown in the following figure.

Which of the following statements is true of tags and resource identifiers for EC2 instances?
A
You can assign tags only to resources that already exist. You can't terminate, stop, or delete a re-source based solely on its tags; you must specify the resource identifier. For example, to delete snap-shots that you tagged with a tag key called DeleteMe, you must use the DeleteSnapshots action with the resource identifiers of the snapshots, such as snap-1234567890abcdef0. To identify re-sources by their tags, you can use the DescribeTags action to list all of your tags and their associated resources.
