- A
Routes advertised to 10.1.1.2 will have the MED set to 50, influencing inbound path selection in AS 65001.
Correct. The route-map sets MED on outbound updates, affecting how AS 65001 selects the path to reach networks in AS 65000.
- B
Routes advertised to 10.1.1.2 will have the MED set to 50, influencing outbound path selection from AS 65000.
Why wrong: Incorrect. MED is used for inbound path selection; it affects how other ASes choose paths to reach the local AS.
- C
Routes received from 10.1.1.2 will have the MED set to 50.
Why wrong: Incorrect. The route-map is applied to outbound updates (out), not inbound.
- D
The MED value will be set to 50 for all routes in the BGP table.
Why wrong: Incorrect. The route-map only affects routes advertised to the specified neighbor, not all routes.
Quick Answer
The correct answer is that routes advertised to 10.1.1.2 will have the MED set to 50, influencing inbound path selection in AS 65001. This is because the route-map SET_MED is applied outbound to the neighbor, and the set metric command modifies the Multi-Exit Discriminator attribute, which is a metric used to tell a neighboring AS which path to prefer when multiple entry points exist into the local AS. On the ENCOR 350-401 exam, this question tests your understanding of BGP path manipulation and the critical distinction between inbound and outbound route-map application—a common trap is confusing the direction, as MED is set outbound to affect inbound decisions. Remember that MED is a hint to the neighbor, not a local preference, and it is only compared when paths come from the same neighboring AS. A useful memory tip: "MED is sent out to influence what comes in."
CCNP Network Function Virtualization Practice Question
This 350-401 practice question tests your understanding of network function virtualization. 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.
Consider the following BGP configuration:
router bgp 65000
bgp router-id 1.1.1.1
neighbor 10.1.1.2 remote-as 65001 neighbor 10.1.1.2 route-map SET_MED out
! route-map SET_MED permit 10 set metric 50
What is the effect of this configuration?

Correct answer & explanation
Routes advertised to 10.1.1.2 will have the MED set to 50, influencing inbound path selection in AS 65001.
The route-map SET_MED is applied to outbound updates to neighbor 10.1.1.2, setting the MED (Multi-Exit Discriminator) attribute to 50. MED is a metric that influences inbound path selection in the neighboring AS (AS 65001), telling its routers which path to prefer when multiple entry points exist into AS 65000. Therefore, option A correctly describes the effect.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between inbound and outbound route-map application, and the trap here is confusing that MED influences inbound path selection in the receiving AS, not outbound path selection from the advertising AS.
Detailed technical explanation
How to think about this question
MED is an optional non-transitive BGP attribute that is exchanged between ASes and is used to discriminate among multiple entry points into the same AS. Lower MED values are preferred. In this configuration, the set metric 50 command under the route-map modifies the MED for all routes sent to 10.1.1.2, which is useful for influencing traffic from AS 65001 to prefer this path over others with higher MED values. Note that MED is typically compared only when paths come from the same neighboring AS.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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.
