A Newspaper conglomerate has a network configured following the schema below. Each branch consists of one LAN and all routers were completely configured and in full working order. However, just after a Network Admin made changes to the NewsC router -- users on that LAN cannot access NewA and NewsB networks. Please investigate and fix the problem. The routers have been configured with the following specifications: The routers are named NewsA, NewsB and NewsC. RIP is the routing protocol. The clocking is provided on the Serial 0 interfaces. The secret password on the NewsC router is "cisco". The subnet mask on all interfaces is the default mask.

Inside Tip: Click on Host F to connect to the Lab C router. For goodness sake -- write down the config(s) for each Lab along with a brief outline of the question before you attempt to do anything. If you do not -- you will fall apart in the exam. Miss a Lab - you're in trouble. Miss both of them and you will not pass the CCNA Exam. The trick here is to compare the output from the "show running-config" command with the configurations that you have written down. Look for a wrong IP address - is the network on the interface configured for RIP - has the clock rate been applied to the appropriate serial interface? The question in this Lab specifies that there is a potential problem with the "NewsC" router based on the premise that it was the last router that the Net Admin applied changes to. Are these changes correct? You do not need to "sniff" around the other routers to find additional issues. Focus on the "NewsC" router changes that may have brought the LAN to its knees. Again - get in the practice of writing down the config(s). Finally, it is always a smart thing to end with a "copy running-config startup-config" command to save your work, right?
