Exhibit As shown in the exhibit, you have implemented CoS classifiers using Differentiated Services Code Point (DSCP) In this scenario, which two statements are correct? (Choose two.)
Correct Answer: A,C
The exhibit shows a custom Behavior Aggregate (BA) classifier named my-classifier for the Differentiated Services Code Point (DSCP) protocol. Importing Defaults (Statement C): The configuration line import default; is crucial. In Junos OS, when you create a custom classifier, you can use this statement to import the default mapping table for all code points that you have not explicitly defined in the current block. This ensures that only the specific traffic types you care about are customized while the rest follows industry-standard defaults. Logical Interface Association (Statement A): In the Junos class-of-service hierarchy, classifiers are typically applied to logical interfaces (e.g., ge-0/0/0.0). While they can sometimes be applied at a higher level, the standard practice for enterprise routing and switching is to associate them with the logical unit to provide granular control over subinterfaces or VLAN-tagged traffic. Why others are incorrect: Statement B is less accurate because the primary binding point in Junos is the unit (logical interface). Statement D is incorrect because the specific classifications defined in the custom block override the defaults; they are not overwritten by them.
