A cloud engineer is installing packages during VM provisioning.
Which of the following should the engineer use to accomplish this task?
A . Cloud-init
B . Bash
C . Docker
D . Sidecar
Answer: A
Explanation:
The cloud engineer should use cloud-init to install packages during VM provisioning. Cloud-init is a tool that allows the customization of cloud instances at boot time. Cloud-init can perform various tasks, such as setting the hostname, creating users, installing packages, configuring network, and running scripts. Cloud-init can work with different cloud platforms and Linux distributions. This is the correct tool to accomplish the task. The other options are incorrect because they are either not suitable for cloud provisioning (Bash or Docker) or not a tool but a design pattern (Sidecar).
