Which AWS CLI command should an administrator use to check all permissions needed to run an action before executing it?

The correct command to use in this scenario is the option that includes the flag to simulate the execution of an action without actually running it. This functionality allows administrators to determine what permissions are required for a specific action before they proceed with executing it.

When you use the dry-run option, the command checks whether the user has the necessary permissions and whether the specified resources exist, providing feedback based on these conditions. This is particularly helpful in understanding and troubleshooting permission requirements in AWS Identity and Access Management (IAM), and it aids in ensuring that the user has the appropriate policies attached before performing potentially disruptive actions.

Understanding this option is critical for maintaining security and operational integrity in the AWS environment, as it helps avoid unintentional errors during processes that could have significant consequences if executed without proper permissions.
