Q: 2
You are implementing traffic engineering in your MPLS network. You must ensure that the MPLS
routes are used to traverse your network. Your solution should not affect IGP routes in your route
tables.
In this scenario, which traffic engineering setting will accomplish this behavior?

Option B
B is the way to go here since 'mpls-forwarding' makes sure only the MPLS traffic engineering paths are used for forwarding, but it doesn't touch regular IGP routing tables. That's what the question is getting at. I'm pretty sure about this since it's straight from Juniper docs. Disagree?
Don’t think it’s B this time, I’m picking D. People sometimes pick A here but that one can be a bit misleading.
D , because bgp can direct traffic paths and sometimes that's how TE is set. But A feels like a trap option.
A isn’t right, B is. With mpls-forwarding, you keep IGP routing untouched and let MPLS pin TE paths, which is the whole point here. Pretty sure that’s what the exam expects-unless they sneak in LSP distribution tweaks.
You want to force MPLS to handle the forwarding without touching IGP routes, so B.
A isn't right here, it's B. Super clear wording in this one.
