Question 4

Which method changes the forwarding decision that a router makes without first changing the routing table or influencing the IP data plane?

    Correct Answer: C

    Policy-based routing (PBR) changes the forwarding decision that a router makes without first changing the routing table or influencing the IP data plane. PBR allows routers to make forwarding decisions based on policies set by network administrators rather than strictly following the routing table. This method enables more flexible and customized routing solutions without altering the fundamental routing information base (RIB) or impacting the forwarding information base (FIB).

PBR takes precedence from Routing table when it comes to routing decisions iff it is configured already. So it makes sense that it is answered as C.

Its D. The key word in this question is first lol... Without FIRST, meaning its changing whatever follows. After the routing table changes the FIB will update and the router will use that for the forwarding decision. Cisco giving us a english exam as well smh..

[Removed]Option: D

So the only answer here that changes the routing table is D, and the router does use that to make forwarding decisions after all so im going with D.

Lol the way its worded can be interpreted 2 different ways.

This is one of those English type questions. You really have to comprehend what they're asking. Without first, meaning changing these things first. That points to the FIB. Any changes made to the routing table/data plane populates the FIB which the routers uses to forward. PBR is thrown in there for confusion because the first portion of the question it fits but then it doesn't make sense once you read the entire question.

No, "without first changing x" means that it DOES NOT change X. Yes, it is "one of those English type questions", but you are misinterpreting it here...

Koume

I think is a spooky question but, i really go for C, as if you take all the sentece says "without first changing the routing table or influencing the IP data plane". when talks the routing table speak as the RIB, but also the Dataplane is clearly talking about the FIB. I understood that means without ifluencing both. and the only one that do tha is PBR.
