300-410 Practice Question: Runs the following command on Router R1: R1# show…
A network engineer runs the following command on Router R1:
R1# show ip policy Interface Route-map
GigabitEthernet0/0 PBR-SET
R1# show route-map PBR-SET
route-map PBR-SET, permit, sequence 10 Match clauses:
ip address (access-lists): 160
Set clauses:
ip next-hop 192.168.1.2
ip tos 184Policy routing matches: 300 packets, 24000 bytes
R1# show access-lists 160
Extended IP access list 160
10 permit ip 10.0.0.0 0.255.255.255 any R1# show interfaces GigabitEthernet0/0
GigabitEthernet0/0 is up, line protocol is up Internet address is 10.0.0.1/24
Based on this output, a packet from source 10.0.0.5 to destination 8.8.8.8 arrives on GigabitEthernet0/0. What is the most likely behavior?
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 packet is forwarded to 192.168.1.2 with the ToS field set to 184.
The packet matches ACL 160 (source 10.0.0.0/8). The route map sets both next-hop and ToS. The next-hop 192.168.1.2 must be reachable for PBR to apply. Assuming it is reachable (not shown but implied by matches), the packet will be forwarded to 192.168.1.2 with ToS set to 184 (which is 0xB8, or IP precedence 5, DSCP 46).
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 packet is forwarded using the routing table because the next-hop is not specified correctly.
Why it's wrong here
The next-hop is specified; the 300 matches indicate it is working.
- ✓
The packet is forwarded to 192.168.1.2 with the ToS field set to 184.
Why this is correct
The route map matches the packet and sets both next-hop and ToS, so the packet is policy-routed with the new ToS value.
- ✗
The packet is dropped because the ToS value is invalid.
Why it's wrong here
ToS 184 is a valid value (binary 10111000).
- ✗
The packet is forwarded to 192.168.1.2 but the ToS is not changed.
Why it's wrong here
The set clause includes ip tos, so ToS is changed.
