Which three statements are true about terms in a policy? (Choose three.)
A.
The order of the terms in a policy is irrelevant.
B.
The action is specified in a then statement.
C.
Terms are optional in a policy.
D.
The match condition can be identified with a from statement.
E.
A from statement is mandatory in a term.
Explanation:
Terms are the basic building blocks of all Junos OS policy. They are essentially if…then statements. If all the match conditions
specified in the from statement are true (or if no from statement is specified), all the actions in the then statement are
executed. You give terms a name. The name has no effect on the evaluation of the term; rather, it provides a meaningful
identifier that you can use when referring to the term.

Policy Components
All policies are composed of the following components that you configure:
Match conditions—Criteria against which a route or packets are compared. You can configure one or more criteria. If all criteria match, one or more actions are applied.
Actions—What happens if all criteria match. You can configure one or more actions.
Terms—Named structures in which match conditions and actions are defined. You can define one or more terms.
The policy framework software evaluates each incoming and outgoing route or packet against the match conditions in a term. If the criteria in the match conditions are met, the defined action is taken.
In general, the policy framework software compares the route or packet against the match conditions in the first term in the policy, then goes on to the next term, and so on. Therefore, the order in which you arrange terms in a policy is relevant.
The order of match conditions within a term is not relevant because a route or packet must match all match conditions in a term for an action to be taken.
