QuestionQ277

Infrastructure and Automation

A developer must satisfy these requirements:

  • Support provisioning up to 500 new virtual machines in private data centers or the public cloud.
  • Ensure the configuration of 400 existing virtual machines remains synchronized and can be updated on demand.
  • Support defining a list of instructions or steps that must run in a precise order to configure a virtual machine.

Which configuration-management solution must the developer use?

  • A Ansible
  • B Docker
  • C Puppet
  • D Terraform
Explanation

Ansible playbooks provide repeatable configuration management and multi-machine deployment. They target managed-node inventories, can be rerun to apply or verify the desired configuration, and execute plays and tasks in a defined top-to-bottom order, making them suitable for ordered VM-configuration procedures at scale.
