問題文
A tenant has been given a database property that names a credential. Which statement describes when that property is used and what a job of the export and import utilities has to write in order to lean upon it?
選択肢
- It is used only where a job names a credential of its own as well, so the two are compared and the job stops with an error whenever the property and the name upon the command line disagree.
- It is used for every statement of the tenant that reaches the host, so the property replaces the credential of the session and the job that names one of its own has that name quietly ignored.
- It is used where the feature at hand offers no way of naming a credential or where naming one is optional, so a job that names no credential of its own has to carry the name of that property as a prefix upon the dump file.
- It is used where the feature at hand offers no way of naming a credential or where naming one is optional, so a job that names no credential of its own has to carry the name of the tenant as a prefix upon the directory object.
