A company wants to use cloud-init to configure VMs in a multi-cloud environment (AWS, Azure, GCP). They want to ensure that cloud-init uses the correct datasource for each cloud. What should they do?

Set 'datasource' to 'Ec2' in /etc/cloud/cloud.cfg.

Create separate images for each cloud with the datasource hardcoded.

Use the 'NoCloud' datasource for all clouds.

Set 'datasource_list' in /etc/cloud/cloud.cfg to include all possible datasources.

A company provisions temporary development VMs in a public cloud. They need each VM to have a user account 'devuser' with an SSH key for immediate access. They also want to disable password authentication for that user. Which cloud-init configuration should they use in user-data?

user: devuser, ssh_authorized_keys: [key], disable_root: true

ssh_authorized_keys: - devuser: key

runcmd: - useradd devuser -m -s /bin/bash, - echo 'key' >> /home/devuser/.ssh/authorized_keys

users: - name: devuser, ssh_authorized_keys: [key], lock_passwd: true

In cloud-init, what is the purpose of user-data?

To provide the instance with a unique hostname and network configuration

To pass configuration directives and scripts that cloud-init will execute on the instance

To store the instance's SSH private key for secure access

To define the instance's resource limits and quotas
