問題文
A site has an external configuration management tool that writes the switch's network files, and after a declarative apply the settings that tool had installed are gone. What has happened?
選択肢
- The external tool's own state has diverged from the switch and it will restore the settings on its next run, so the situation resolves itself as long as the two are not run in the opposite order again and the site therefore only has to be careful about the sequence in which it invokes them.
- The apply failed partway through and left the switch in an inconsistent state, so a part of the external tool's settings survived while all the others were dropped.
- The apply replaced those files with what the declarative model holds, removing what was added by hand or by the external tool.
- The external tool's settings were rejected as invalid at the time they were written, and the switch has been running on the declarative values alone from that point onward.
