An inventory directory holds two files. The earlier of the two names a group as the child of another group, and the hosts of that child group are listed in the later one. The run ends with an error while the inventory is read. Which statement explains that?
選択肢
- Every source is finished on its own, and a group that has no host in it yet is thrown away at the end of the source that named it.
- A group that is named as a child has to carry the marker for children in each of the files it turns up in, and one of the two here is without it.
- Every source is finished on its own, and a group may be named as the child of another group in the last of the sources alone.
- The two files are taken in as one source between them, and a group whose name turns up twice in a source is an error the second time around.
