NSE7 Advanced Networking and SD-WAN Practice Question
An administrator configures a route-map to match prefix-list 'PREFIX' and set metric 20. Which OSPF route redistribution uses this route-map correctly?
⚠ Common exam trap
Watch out — candidates often confuse the global 'set route-map' under 'config router ospf' (which is not a valid command in FortiOS) with the per-redistribution 'set route-map' inside 'config redistribute', leading them to select option C instead of A.
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
✓
config router ospf config redistribute "connected" set route-map "RM" end
In FortiOS, the route-map is applied to a specific redistribution rule under 'config router ospf' using the 'set route-map' command within the 'config redistribute' block. This correctly associates the route-map 'RM' with the redistribution of connected routes into OSPF, matching the prefix-list 'PREFIX' and setting the metric to 20.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
config router ospf config redistribute "connected" set route-map "RM" end
Why this is correct
Route-map is applied in the redistribute configuration.
- ✗
config router policy config route-map edit "RM" config rule set match-ip-address "PREFIX" set set-metric 20 end end
Why it's wrong here
This defines the route-map but does not apply it.
- ✗
config router ospf set route-map "RM"
Why it's wrong here
Route-map is not set at the global OSPF level.
- ✗
config router prefix-list edit "PREFIX" set rule permit 10.0.0.0/8 end
Why it's wrong here
This defines a prefix-list, not a route-map.
