السؤال #1
You have implemented IPv6 automatic 6-to-4 tunneling between three IPv6 subnets as shown in the network exhibit. (Click the Exhibit(s) button.) You have used the following commands to implement the automatic 6-to-4 tunnel: Your supervisor has assigned the task of verifying the automatic 6-to-4 tunnel to one of your colleagues. Your colleague runs the show running-config command and finds that incorrect IPv6 addresses have been assigned to the tunnel interfaces of the routers. Which of the following IPv6 ad
A. 2002::c0a8:2d01/64 to the Fa0/1 interface of rtrA
B. 2002:c0a8:4b01::1/64 to the Fa0/1 interface of rtrB
C. 2002:c0a8:7d01::1/64 to the Fa0/1 interface of rtrC
D. 2002:c0a8:4b01::1/64 to the Fa0/1 interface of rtrA

السؤال #11
R2 is a route reflector, and R1 and R3 are route reflector clients. The route reflector learns the route to 172.16.25.0/24 from R1, but it does not advertise to R3. What is the reason the route is not advertised?A. R2 does not have a route to the next hop, so R2 does not advertise the prefix to other clients.
B. Route reflector setup requires full IBGP mesh between the routers
C. In route reflector setup, only classful prefixes are advertised to other clients
D. In route reflector setups, prefixes are not advertised from one client to another
