L3 Switching methods

[amrelec]

Which one of the methods below, in Layer 3 switching, uses a forwarding information base (FIB)?

A. Route caching

B. Demand-based switching

C. Flow-based switching

D. Topology-based switching

my answer (according to the CCNP BCMSN for David Hucaby) Page 295 is Choice "D" [Topology-based switching]

but,

I read it as "A" in some other sources.

What's the Correct answer?

Hello,

D is the right one

FIB is one of  the CEF tables, and CEF is topology driven

Hope to help
