The answer is that the weight command sets the weight of all routes learned from neighbor 10.6.6.7 to 200, making them preferred over routes with lower weight. This is correct because BGP weight is a Cisco-proprietary, locally significant attribute where a higher weight is always preferred over a lower one, and the default weight for eBGP routes is 0. On the Cisco CCNP ENARSI 300-410 exam, this question tests your understanding of BGP path selection and the weight attribute configuration, often appearing in scenarios where you must influence outbound traffic without altering attributes sent to other routers. A common trap is confusing weight with local preference—remember that weight is local to the router and takes precedence over local preference in the BGP best-path algorithm. For a quick memory tip, think “Weight wins first” since it is the very first tiebreaker checked in the BGP decision process.

This 300-410 practice question tests your understanding of bgp troubleshooting. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It sets the weight of all routes learned from 10.6.6.7 to 200, making them preferred over routes with lower weight.
The weight command assigns a weight value to routes from a specific neighbor. Weight is a Cisco-specific attribute that is local to the router. Higher weight is preferred over other routes. The default weight for eBGP routes is 0, so weight 200 makes routes from this neighbor preferred.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
It sets the weight of all routes learned from 10.6.6.7 to 200, making them preferred over routes with lower weight.
Why this is correct
Weight is locally significant and higher weight wins.
It sets the weight of routes sent to 10.6.6.7 to 200.
Why it's wrong here
The weight command is applied to routes received from the neighbor.
✗
It has no effect because weight is only configurable under route-map.
Why it's wrong here
Weight can be configured directly under the neighbor or via route-map.
✗
It sets the MED value to 200 for routes from this neighbor.
Why it's wrong here
Weight is a different attribute than MED.
Common exam traps
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Trap categories for this question
Command / output trap
The weight command is applied to routes received from the neighbor.
Detailed technical explanation
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
OSPF neighbours must agree on key parameters.
Router ID selection can affect neighbour relationships and LSDB output.
OSPF cost influences the preferred path.
A route can appear in OSPF information but not become the installed route.
TExam Day Tips
→Check area mismatch first when OSPF adjacency fails.
→Review passive interfaces when a network is advertised but no neighbour forms.
→Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
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.

What is the correct answer to this question?
The correct answer is: It sets the weight of all routes learned from 10.6.6.7 to 200, making them preferred over routes with lower weight. — The weight command assigns a weight value to routes from a specific neighbor. Weight is a Cisco-specific attribute that is local to the router. Higher weight is preferred over other routes. The default weight for eBGP routes is 0, so weight 200 makes routes from this neighbor preferred.
