Consider the network below, and assume that a provider network only wants to carry traffic to or from its customer networks. Which of the following statements are true? O B will advertise a route Bx to only one of peers A, C and D, since that will force all route traffic to x to be routed via that single peer, allowing B to peer with fewer provider networks. O B will advertise a route Bx to D but not to A, since B knows that D can reach both w and z. O B will advertise a route Bx to A C and D, since A, C and D need to know how to route to B's customer network x. O B will advertise a route Bx to A and D but not C, since it knows that C is also a provider for X
