💡 Hint

Common Mistakes

Using the instance ID instead of the AMI ID.

Using the AMI name or instance type instead of the AMI ID.

The deregister-image command requires the AMI ID, which starts with 'ami-'. Using an instance ID or other values will cause an error.

💡 Hint

Common Mistakes

Using AMI ID instead of instance ID for --instance-id.

Not quoting the description string.

The --instance-id requires the instance ID, and --description needs a string describing the AMI. The --no-reboot flag prevents reboot during image creation.

5fill in blank

hard

Fill all three blanks to launch an EC2 instance with a specific AMI, instance type, and key pair.

AWS

aws ec2 run-instances --image-id [1] --instance-type [2] --key-name [3] --count 1

💡 Hint

Common Mistakes

Using instance ID instead of AMI ID for --image-id.

Using AMI ID instead of instance type for --instance-type.

Using instance ID instead of key pair name for --key-name.

The --image-id specifies the AMI, --instance-type sets the size of the instance, and --key-name provides the SSH key pair for access.
