QUESTION NO: 1

You are a Cisco certified expert. You have been contracted by the Labvn Pro chain to fix a
problem that was caused by a MCP certified technician who could not complete the
configuration of the routers. This Labvn 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 Lab1, Lab2, and
Lab3, 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 Lab1, Lab2, and Lab3.
• RIP is the routing protocol
• Clocking is provided on the serial 0 interfaces
• The password on each router is "cisco"
• The subnet mask on all interfaces is the default mask.
• The IP addresses are listed in chart below.

Lab1
E0 192.168.27.1
E1 192.168.29.1
S0 192.168.31.1
Secret password: cisco

Lab2
E0 192.168.35.1
S0 192.168.33.1

QUESTION NO: 2

You are a network technician at Cisco, Inc. Cisco has recently opened a third office in a
foreign country and bought a router to connect this office to the other two already on the
network. The names of the routers are Lab1, Lab2, and Lab3. Configure the Lab3's router's IP
addresses on the E0 and S1 interfaces so that the E0 interface receives the first usable
subnet while the S1 interface receives the second usable subnet from the network
192.168.101.0/28. Both interfaces should receive the first available IP of the subnet. The zero
subnet should not be used. The routers have been configured
with the following specifications.
 The routers are named Lab1, Lab2, and Lab3.
 RIP is the routing protocol.
 Clocking is provided on the serial 0 interfaces
 The secret password on the Lab3 router is "cisco"

 The subnet mask of all networks other than 192.168.101.0 is the default mask.
 The IP addresses are listed in the chart below.

QUESTION NO: 3

Three sites, Lab1, Lab2, and Lab3 are connected via a WAN. At each site a router provides
serial connectivity to the Wan and an Ethernet connection to a LAN. All three routers are
configured, and the network is functional. Configure and apply an access list will prevent
telnet access to the Lab1 router while allowing all other traffic to pass. The access list
should not contain more than three (3) statements and should be applied to the Lab1 router.
The routers have been previously configured with the following specifications:
 The routers are named Lab1, Lab2, and Lab3.
 RIP is the routing protocol.
 The clocking signal is provided on the serial 0 interfaces.
 All passwords on all routers are "cisco".
 The subnet mask on all the interfaces is the default mask.
 IP addresses are listed in the chart below.

Lab1
E0 192.168.149.1
S0 192.168.199.1
Secret password: cisco

Lab2
E0 192.168.155.1
