Example of Assessment: Laboratory/Practical – Part 1
Addressing and Routing
This is an individual assessment
Assessment Duration: 50 minutes
The sample test is designed to assist you in preparation for the actual Practical Assessment 1.
Instructions:
• You have 50 minutes to complete the actual assessment. This exam is an open-book,
individual exam.
• You may use Cisco Packet Tracer to validate your answers as well as to exercise your
problem-solving skills. However, Packet Tracer files will not be marked and should not be
uploaded.
• In the actual test, there are three (3) sections including addressing, routing and
troubleshooting. In this sample test, there are only two (2) sections including addressing and
routing.
• You can use this sample test to test yourself with the time limits challenge.

SAMPLE TEST SOLUTIONS
Scenario: You have been given a block of IPv4 addresses 193.168.0.0/24 to create 8 subnets. Based
on the addressing instructions, (given in Section B) and routing specifications (given in Section C),
you are required to assign designated IP addresses for the hosts and router interfaces. Enter your
answers in the boxes in the tables below.
Section A - Addressing
This scenario involves with three generic routers (Router-PT). The routers are connected through a
point-to-point serial link as shown in Figure 1:
• R1 – R2 and R1 – R3 are connected through serial links. R3 is the ISP’s router.
• R1’s Serial2/0 interface connects to R2’s Serial2/0 interface.
• R1’s Serial3/1 interface connects to R3’s Serial2/0 interface.
• R1 connects to Subnets 1, 2 and 3.
• R2 connects Subnets 1, 5, 6, 7 and 8.
• The addresses of Subnet 1 are reserved for the link between R1 and R2.
• Each FastEthernet interface of the router is connected to a generic switch. Add one server to
each subnet (except Subnet 1) via a switch.

• Assign the last usable IP address of Subnet 6 on SERVER6.
Subnet 7 connects to router R2:
• Assign the first usable IP address of Subnet 7 on the interface Fa4/0 of R2.
• Assign the last usable IP address of Subnet 7 on SERVER7.
Subnet 8 connects to router R2:
• Assign the first usable IP address of Subnet 8 on the interface Fa5/0 of R2.
• Assign the last usable IP address of Subnet 8 on SERVER8.

Section B - Routing
This section provides the routing specifications. Your routing must follow these specifications
accordingly.
• From R1, configure one default route pointing to R3.
• From R1, configure one static route to reach the subnets 5-8 that are attached to R2.
• From R2, configure one default route pointing to R1.
• From R3, configure one static route to reach all other subnets that are attached to R1 and R2.
Routing recording: Use the following tables to record static routes for R1, R2, and R3.

workstations accordingly as shown in Figure1.
II. IP Addressing Configuration
Task 2: Subnet the Address Space
Use Table 1 to record the subnet information.
