An organization's cloud environment has automated configuration management policies in place to maintain server baselines and update security patches. After a recent deployment of a new application, they noticed performance issues and suspected that an unauthorized change to server configurations could be the cause. Which of the following would BEST help identify the unauthorized changes?
Manually inspect the configurations on all cloud servers to find differences.
Review the configuration management database (CMDB) for discrepancies between the current and baseline configurations.
Increase computing resources to the servers to improve performance.
Reboot the server to restore the previous configuration state.
