[All 4A0-100 Questions]

Where would you expect to find a P router in a service provider's network?

AAt the edge of the provider's network facing the customer.

BAt the edge of the customer's network facing the provider.

CIn the core of the provider's network.

DOn the customer premises.

Show Suggested Answer

Suggested Answer: C

A P router (Provider router) is located in the core of the service provider's network. Its functions include:

Forwarding MPLS-labeled packets between PE routers.

Not interacting directly with customer routes or routing instances.

Having no knowledge of VPN routing or customer-specific services.

Option C is correct -- P routers sit in the MPLS core, isolated from customer edge.

I’m not so sure. Could it be A? Edge routers are important too.

I remember studying that P routers handle traffic between different networks, so option C makes sense to me.

I think a P router is more likely to be in the core of the provider's network, but I'm not completely sure.
