問題6

You must document that before your application applies any configuration changes to a device, the application runs those changes through a set of predefined, automated consistency tests called "ACT-CHECK10". The application applies changes only after the test has completed without any ERRORS or WARNINGS.
Which statement about these requirements is true?

A. The system should call the function app.ACT_CHECK10("config-changes.txt") method and capture the output. The system shall than go through the output to count the number of ERRORS and WARNINGS reported by the test. If the total number of ERRORS and WARNINGS is equal to 0, the system shall proceed to run app.ApplyChanges("config-changes.txt").

B. The system should test the configuration before applying it.

C. After applying the configuration changes the user should ping the device to ensure that everything still works.

D. Prior to applying the configuration changes to the device, the system shall run consistency test ACT_CHECK10, and proceed to applying changes only if no errors and/or warnings are reported by the test.

E. The system should run consistency checks prior to applying configuration changes.
