問題文
An operations team wants one tool that installs and configures packages inside dozens of already running instances and that selects those instances by tag instead of by address. Which approach fits?
選択肢
- An Ansible playbook run against a static inventory file that lists every address so each task converges a host to the declared state even while the fleet keeps changing.
- A shell script run by hand from an operator laptop against each address in turn so the packages land in the same order.
- A Terraform configuration run against the tenancy so the instances are created again from the start whenever a package version changes on a host.
- An Ansible playbook run against the dynamic inventory plugin for the tenancy so each task converges a host to the declared state and the selection follows the tags that the hosts carry.
