Correct Answer: 4

Explanation: A tag is a label that you assign to an AWS resource. Each tag consists of a key and an optional value, both of which you define. Tags enable you to categorize your AWS resources in different ways, for example, by purpose, owner, or environment.

INCORRECT: “Metadata” is incorrect. Instance metadata is data about your instance that you can use to configure or manage the running instance.

INCORRECT: “Custom filters” is incorrect. Custom filters are not used for categorization.

CORRECT: “Tags” is the correct answer.
