An administrator is debugging why a cloud-init script is not running on a VM. The script is in user-data and starts with #!/bin/bash. They check /var/log/cloud-init.log and see that the 'scripts-user' module ran, but the script did not execute. What is a possible cause?

The instance has already booted once and cloud-init is using cached user-data.

The script is placed in the wrong directory.

What is the config drive datasource in cloud-init?

A network service that provides metadata to the instance

A special partition on the instance's root disk

A virtual disk attached to the instance that contains metadata and user-data

A configuration file stored in the instance's /etc directory

A company uses cloud-init to install packages on VMs. They have a private package repository that requires authentication. How can they configure cloud-init to use the repository credentials?

Use the 'runcmd' module to run 'yum-config-manager' with credentials.

Use the 'apt' module with 'sources_list' and 'keys'.

Use the 'write_files' module to create a repository config file with credentials.

Which of the following is a core feature of cloud-init?

Applying configuration and scripts to an instance during its first boot

Automated scaling of instances based on load
