問題文
A team writes a nonnative YANG data model for a device running Junos OS 24.4 and puts a constraint into it with the must keyword. The device then commits configuration data that breaks the constraint without a word about it. Which statement explains that?
選択肢
- The path expressions of the leafref, the must and the when keywords are evaluated for native statements alone, and the three keywords are left out of the schema that a nonnative model builds.
- The path expressions of the leafref, the must and the when keywords are evaluated by the client application that sends the configuration data, because the device itself carries no engine of its own for expressions of that kind.
- The path expressions of the leafref, the must and the when keywords are left unevaluated by default while a commit operation is under way.
- The path expressions of the leafref, the must and the when keywords are evaluated while the module is added to a package.
