300-410 Practice Question: Which TWO statements about Policy-Based Routing…
Which TWO statements about Policy-Based Routing (PBR) are true? (Choose TWO.)
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
✓
PBR is applied on the inbound interface of the router.
PBR uses a route-map with match and set commands to override the routing table for selected traffic. The 'set interface' command can specify an outgoing interface, and if that interface is down, the packet is dropped unless a 'set ip next-hop' is also configured as a backup. PBR does not affect the router's own originated traffic by default. The 'set ip default next-hop' is used only when there is no explicit route in the routing table, not for overriding an existing route. PBR is applied on the inbound interface.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
PBR is applied on the inbound interface of the router.
Why this is correct
PBR is configured with 'ip policy route-map' under the interface, which processes incoming packets.
- ✗
If a 'set interface' command specifies a down interface, the packet is automatically routed using the routing table.
Why it's wrong here
If the specified interface is down, the packet is dropped unless a fallback 'set ip next-hop' is configured.
- ✗
PBR can be used to override the routing table for locally generated packets.
Why it's wrong here
By default, PBR does not apply to locally generated packets; 'ip local policy route-map' is needed for that.
- ✗
The 'set ip default next-hop' command overrides the routing table even when a route exists.
Why it's wrong here
The 'set ip default next-hop' is only used when there is no explicit route in the routing table.
- ✓
PBR uses a route-map to define match criteria and set actions for traffic.
Why this is correct
The route-map contains match statements (e.g., match ip address) and set statements (e.g., set ip next-hop) to control traffic forwarding.
