Which description of Route Policy is correct? (Multiple choice)

Question

Options

• AThe If-match clause is used to determine the matching conditions of the node, and the apply clause is used to define the routing behavior through filtering.
• BThe filtering rule relationship of the If-match clause is "AND", that is, all if-match clauses of the node must match
• CThe relationship between Route-Policy nodes is "or". As long as it passes the filtering of one node, it can pass the Route-Policy.
• DA Route-Policy consists of multiple nodes. A section can contain multiple If-match and apply clauses

• A

Explanation

All four options correctly describe Route Policy behavior, making this an "all of the above" question.

A is correct because Route Policy uses two distinct clause types: if-match defines which routes qualify (matching conditions like prefix, AS path, community), while apply defines what happens to matched routes (setting attributes like local-preference or MED).

B is correct because within a single node, multiple if-match clauses use AND logic - a route must satisfy every if-match condition in that node to be considered a match for that node.

C is correct because across nodes, the logic is OR - the route is evaluated against each node sequentially, and as soon as it matches one node's conditions, the corresponding action (permit/deny) applies and evaluation stops.

D is correct because a Route Policy is structurally a list of numbered nodes, and each node can contain any number of if-match and apply clauses working together.

Memory tip: Think of nodes as OR gates stacked vertically, and if-match clauses within a node as AND gates in a single row - a route must pass ALL filters in one row to trigger that row's action, but only needs to pass ONE row to exit the policy. This "vertical OR, horizontal AND" mental model covers all four facts at once.
