This 350-401 practice question tests your understanding of bgp. 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.

What is the effect of this configuration?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Routes received from 10.0.0.2 will have their origin set to incomplete, making them less preferred compared to IGP origin.
The route-map SET_ORIGIN is applied as an inbound filter to neighbor 10.0.0.2. When a route is received, the 'set origin incomplete' command changes the origin attribute to incomplete (value 2). In BGP path selection, origin incomplete is the least preferred origin type, making these routes less preferred than routes with IGP (value 0) or EGP (value 1) origin.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Routes received from 10.0.0.2 will have their origin set to incomplete, making them less preferred compared to IGP origin.
Why this is correct
Correct. Incomplete origin is the least preferred.
Related concept
Read the scenario before looking for a memorised answer.
✗
Routes sent to 10.0.0.2 will have their origin set to incomplete.
Why it's wrong here
Incorrect. The 'in' keyword applies to inbound updates.
✗
The router will not advertise any routes with origin incomplete to other peers.
Why it's wrong here
Incorrect. The origin is changed, but routes are still advertised.
✗
The configuration is invalid because origin cannot be changed with a route-map.
Why it's wrong here
Incorrect. Origin can be set with route-map.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the directionality of route-maps (in vs out) and the fact that origin can be modified with a route-map, leading candidates to mistakenly think the route-map applies to outbound updates or that origin is immutable.
Trap categories for this question
Keyword trap
Incorrect. The 'in' keyword applies to inbound updates.
Detailed technical explanation
How to think about this question
The BGP origin attribute is a well-known mandatory attribute that indicates how the route was introduced into BGP: IGP (0) via network command, EGP (1) via EGP protocol, or incomplete (2) via redistribution. Changing origin to incomplete on inbound routes can be used to deprioritize specific external routes without using AS-path prepending or local preference, which is useful in multi-homed scenarios where you want to influence return traffic without altering other attributes.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A network engineer at a university connects two campus buildings via a fibre link. Both routers run OSPF, but no adjacency forms — even though both routers can ping each other. The engineer finds one router is in area 0 and the other in area 1. OSPF adjacency requires matching area numbers, hello/dead timers, and network type. IP reachability alone is not enough.
