300-410 Practice Question: Router R2 has the following configuration: ```…

Router R2 has the following configuration:

```

interface GigabitEthernet0/2
 ip address 10.2.2.2 255.255.255.0
 ip policy route-map CHECK

! route-map CHECK permit 10 match ip address 101 set interface GigabitEthernet0/3 !

access-list 101 permit tcp any any eq 80

``` What is the effect of 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

✓

Incoming TCP packets with destination port 80 on G0/2 are forwarded out G0/3, overriding the routing table.

The route-map matches TCP traffic with destination port 80 (HTTP) and sets the output interface to GigabitEthernet0/3. This is applied inbound on GigabitEthernet0/2.

Answer analysis

Option-by-option breakdown

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

  • ✓

    Incoming TCP packets with destination port 80 on G0/2 are forwarded out G0/3, overriding the routing table.

    Why this is correct

    PBR matches the ACL and sets the output interface, bypassing the routing table.

  • ✗

    Outgoing TCP packets with source port 80 on G0/2 are forwarded out G0/3.

    Why it's wrong here

    PBR is applied inbound, and the ACL matches destination port 80, not source.

  • ✗

    All TCP traffic is forwarded out G0/3 regardless of port.

    Why it's wrong here

    The ACL specifically matches port 80, so only HTTP traffic is affected.

  • ✗

    The configuration is invalid because 'set interface' cannot be used with a route-map.

    Why it's wrong here

    'set interface' is a valid PBR action.

Variation 1. Which statement about PBR and the 'set interface' command is correct?

medium
  • A.The 'set interface' command can only be used with point-to-point interfaces.
  • B.If the specified interface is down, the router uses the routing table.
  • C.The 'set interface' command requires a next-hop IP address to be specified.
  • ✓ D.The 'set interface' command forces the packet out the specified interface, and if the interface is down, the packet is dropped.

Why D: The 'set interface' command forces the packet out a specific interface, overriding the routing table. If the interface is down, the packet is dropped unless a fallback is configured.
