I didnt add any answers. THe dumps i was using had a lot incorrectanswers. But you can get correct answers from dumps and 9tut.com...i just want to share my questions before i sleep. I have to do at least this for you guyz.. . Please make sure do all simulations and questions in 9tut.com before you do exams and i will keep post all new questions soon.

After adding R3 router, no routing updates are being exchanged between R3 and the new location. All other inter connectivity and Internet access for the existing locations of the company are working properly.
The task is to identify the fault(s) and correct the router configuration to provide full connectivity between the routers.
Access to the router CLI can be gained by clicking on the appropriate host. All passwords on all routers are cisco.
IP addresses are listed in the chart below.
