You are an employee of ISP A. You must not allow traffic between ISP B and ISP C to cross your network, but customers of ISP B and ISP C must be able to reach your customers.Referring to the exhibit, which two actions would do this? (Choose two.)
A.
Use communities to identify and filter routes.
B.
Use policy to filter routes on AS number.
C.
Use origin code to identify and filter routes.
D.
Use the well-known no-advertise community.
I think D is not corret. Using no-advertise community is meaning all of routers in ISP A cannot receive any routes from R1?

D is incorrect since “no-advertise” well-known community does not exist.

The right answers must be A & B.
Answers C & D simply don’t make sense:
The Origin code sheds no light on who the source of the route advertisement is so its useless here.
If we use the no-advertise well-known community, then routes learnt from ISP B are still advertised to ISP C and vice-versa leading to transit traffic.
