- A
If a packet matches a route-map sequence with a 'permit' keyword, the set actions are applied, and no further sequences are evaluated.
If a packet matches a route-map sequence with a 'permit' keyword, the set actions are applied, and no further sequences are evaluated. This is correct.
- B
If a packet matches a route-map sequence with a 'deny' keyword, the packet is dropped immediately.
Why wrong: If a packet matches a route-map sequence with a 'deny' keyword, the packet is not dropped; instead, the route-map skips to the next sequence. This is incorrect.
- C
The 'match ip address' command in a PBR route map can reference a named or numbered ACL, but not a prefix list. [CORRECT]
Correct. In PBR, the 'match ip address' command can reference either a named or numbered standard/extended ACL, but it cannot directly reference a prefix list. To use a prefix list, a separate 'match ip address prefix-list' command is required.
- D
If no sequence in a PBR route map matches a packet, the packet is forwarded using the routing table (normal routing).
If no sequence in a PBR route map matches a packet, the packet is forwarded using the routing table (normal routing). This is correct.
- E
The 'set ip next-hop' command can be used in a route-map sequence with a 'deny' keyword to override the default behavior.
Why wrong: The 'set ip next-hop' command is used in a permit sequence, not a deny sequence. Using it in a deny sequence does not override the default behavior. This is incorrect.
PBR Route-Map Sequence Numbers
This 300-410 practice question tests your understanding of policy-based routing (pbr). Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: pBR route-map processing. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO statements about PBR and route-map sequence numbers are true? (Choose TWO.)
Quick Answer
The answer is that if no sequence in a PBR route map matches a packet, the packet is forwarded using the routing table via normal routing. This is correct because route maps used for Policy-Based Routing are evaluated in ascending sequence number order, and each sequence contains match and set statements; when a packet fails to match any permit sequence, the implicit deny at the end of the route map is triggered, meaning the packet is not policy-routed but instead follows the standard destination-based routing table. On the Cisco CCNP ENARSI 300-410 exam, this concept tests your understanding of how PBR route-map sequence numbers control traffic flow, and a common trap is assuming that an unmatched packet is dropped—it is not, it simply reverts to normal routing. Remember that the 'match ip address' command can reference an ACL or prefix list, and the 'set' commands in a permit sequence execute only when match conditions are met. Memory tip: "No match, no PBR—back to the routing table."

Correct answer & explanation
If a packet matches a route-map sequence with a 'permit' keyword, the set actions are applied, and no further sequences are evaluated.
Route maps used for PBR are evaluated in sequence number order. Each sequence can have match and set statements. If a packet matches a permit sequence, the set actions are applied and evaluation stops. A deny sequence does not drop the packet; it causes the router to skip to the next sequence. If no sequence matches, the packet is forwarded using normal routing (implicit deny). In PBR, the 'match ip address' command can reference a named or numbered ACL, but not a prefix list. To match a prefix list, you must use the 'match ip address prefix-list' command separately.

Key takeaway
PBR route-map processing
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
