3.You are a Cisco certified expert. You have been contracted by the TestKing Pro chain to fix a problem
that was caused by a MCP certified technician who could not complete the configuration of the routers.
This TestKing Pro chain has three stores and wanted to maintain their bicycle repair business in a centralized manner through network connectivity. They then asked the local MCP certified technician to
configure the routers, but the technician failed to establish connectivity among the routers.
The routers are named TestKing1, TestKing2, and TestKing3, respectively.
Identify the faults(s) and make the appropriate change(s) to rectify the configuration of the routers. The
MCP technician configured the routers with the specification that follows:
.The routers are named TestKing1, TestKing2, and TestKing3.
.RIP is the routing protocol
.Clocking is provided on the serial 0 interfaces
.The password on each router is “testking“
.The subnet mask on all interfaces is the default mask.
.The IP addresses are listed in chart below.
