300-410 Policy-Based Routing (PBR) Practice Question

This 300-410 practice question tests your understanding of policy-based routing (pbr). This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.

Router R6 has the following configuration:

```

interface GigabitEthernet0/7
 ip address 10.6.6.6 255.255.255.0

! route-map PBR-MISS permit 10 match ip address 104 set ip next-hop 192.168.4.1 !

access-list 104 permit ip 10.6.6.0 0.0.0.255 192.168.0.0 0.0.255.255

``` What is missing in this configuration?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

The interface is missing the 'ip policy route-map PBR-MISS' command.

The configuration shown includes the 'ip policy route-map PBR-MISS' command on the interface, making the policy routing active. The route-map and ACL are correctly configured. Therefore, no missing configuration element exists among the options.

Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The interface is missing the 'ip policy route-map PBR-MISS' command.

    Why this is correct

    The interface already has the 'ip policy route-map PBR-MISS' command, so this is not missing.

    Related concept

    Standard ACLs match source addresses.

  • The route-map is missing a 'set interface' command.

    Why it's wrong here

    A 'set interface' command is not required; 'set ip next-hop' is sufficient for PBR.

  • The ACL is missing a 'deny any any' statement.

    Why it's wrong here

    ACLs do not necessarily need a 'deny any any' statement; traffic not matching the permit is handled normally.

  • The route-map sequence number must be 1.

    Why it's wrong here

    Route-map sequence numbers can be any number, not just 1.

Common exam traps

Common exam trap: ACLs stop at the first match

ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.

Trap categories for this question

  • Command / output trap

    A 'set interface' command is not required; 'set ip next-hop' is sufficient for PBR.

Detailed technical explanation

How to think about this question

ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.

KKey Concepts to Remember

  • Standard ACLs match source addresses.
  • Extended ACLs can match source, destination, protocol and ports.
  • The first matching ACL entry is used.
  • There is usually an implicit deny at the end.

TExam Day Tips

  • Check inbound versus outbound direction.
  • Read the ACL from top to bottom.
  • Look for a broader permit or deny above the intended line.

Key takeaway

ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

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.

Visual reference

Source Router + ACL permit 10.0.0.0/8 deny any Server 10.0.0.5 ✓ 192.168.1.1 ✗ dropped ACLs evaluate top-down; first match wins — implicit deny all at end

What to study next

Got this wrong? Here's your next step.

Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related 300-410 ACL questions on filtering logic and placement.
