Question
Which of the following can you use to run a bootstrap script while launching an Amazon Elastic Compute Cloud (Amazon EC2) instance?Question 5Answera.Amazon EC2 instance metadatab.Amazon EC2 instance configuration datac.Amazon EC2 instance AMI datad.Amazon EC2 instance user data
Solution
The correct answer is d. Amazon EC2 instance user data.
Here's why:
When you launch an instance in Amazon EC2, you have the option to pass user data to the instance that can be used to perform common automated configuration tasks and even run scripts after the instance starts. This user data is a feature provided by Amazon EC2 to handle user-defined, instance-specific metadata.
You can use this feature to pass bootstrap scripts or other configuration information to your instance upon launch. The data is not automatically executed, but is available for you to use.
The other options, such as instance metadata, configuration data, and AMI data, do not provide the functionality to run scripts at the launch of an instance.
