Free Cisco 350-801 Actual Exam Questions - Question 5 Discussion

A vs C? Normalization usually means changing called number format before routing.

B. Toll fraud restriction in the IOS router offers a direct way to block unauthorized calls at the network edge, which is more effective than just route patterns inside UCM.

Guessing D here. Ad hoc conference restriction stops users from setting up random conferences that might be exploited to generate toll charges without authorization. The other options focus on routing or router settings, but this one directly blocks a common fraud tactic inside the UCM system itself. It’s less about where calls go and more about what users can do once connected.

A/B? A seems logical because route patterns limit where calls can go within UCM, which can stop unwanted toll calls. But B also makes sense since routers can add another layer of control on outbound calls. The question specifically says “in Cisco UCM,” so I’m thinking B might be outside UCM’s scope, but it’s still relevant for preventing toll fraud overall. C and D don’t really address toll fraud directly, so probably less likely.

Maybe A makes more sense since route patterns directly control call routing in Cisco UCM, which can block unauthorized toll calls. B seems more about router-level controls, not UCM specifically.

Isn’t toll fraud mostly about controlling outbound calls? Wondering if B fits best here.
