This is an individual assessment
Assessment Duration: 50 minutes
The sample specifications are designed to assist you in preparation for the actual Practical
Assessment 1.
Instructions:
You have 50 minutes to complete the actual assessment.
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 sections including addressing, routing and troubleshooting.
In this sample test, there are only 2 sections including address and routing.
The actual exam is closed book. Any type of reference materials, either from lecture notes
or practical exercises, are NOT allowed.
The usage of personal computing devices, including mobile phones, calculators and laptops
are NOT allowed.
Internet access is NOT allowed.

Scenario: You have been given a block of IPv4 addresses 192.168.0.0/24 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. Devices
which are connected with serial links must have a reference clocking to synchronize each
other. Only one end of the serial link controls the clock rate like a master/slave relationship.
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.

(1) IP Addressing Instructions
2 usable addresses 100.0.0.0/24 are used for the link between routers R1 and R3:
Assign the first usable IP address of 100.0.0.0/24 on the interface Se3/0 of R1.
Assign the second usable IP address of 100.0.0.0/24 on the interface Se2/0 of R3.
Two addresses of Subnet 1 are used for the link between routers R1 and R2:
Assign the first usable IP address of Subnet 1 on the interface Se2/0 of R1.
Assign the second usable IP address of Subnet 1 on the interface Se2/0 of R2.
Subnet 2 connects to router R1:
Assign the first usable IP address of Subnet 2 on the interface Fa0/0 of R1.
Assign the last usable IP address of Subnet 2 on SERVER2.
Subnet 3 connects to router R1:
Assign the first usable IP address of Subnet 3 on the interface Fa1/0 of R1.
Assign the last usable IP address of Subnet 3 on SERVER3.
Subnet 4 is reserved for future use.
Subnet 5 connects to router R2:
Assign the first usable IP address of Subnet 5 on the interface Fa0/0 of R2.
Assign the last usable IP address of Subnet 5 on SERVER5.
Subnet 6 connects to router R2:
Assign the first usable IP address of Subnet 6 on the interface Fa1/0 of R2.
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.

SAMPLE TEST
5 / 5
I. Network Topology
Task 1: Build a Network Topology
You may use Cisco Packet Tracer to build a network topology and label the routers and
workstations accordingly as shown in Figure1.
II. IP Addressing Configuration
Task 2: Subnet the Address Space
Use Table 1 to record the subnet information.
Task 3: Configure IP Addressing
Use Table 2 Addressing Table to assign the specified IP addresses to workstations and
router interfaces, according to the IP addressing specifications.
Task 4: Test and Troubleshoot
After you have configured your addressing assignment with Packet Tracer, you can Ping
utility to verify your answer and exercise your troubleshooting skills.
III. Routing Configuration
Task 5: Record Static Routing Tables
Use Tables 3-5 to record static routing information for R1, R2 and R3.
Task 6: Configure Static Routing
Implement static routing for each router.
Task 7: Test and Troubleshoot
Once again, after you have configured static routing with Packet Tracer, you can use Ping
utility to verify your routing configuration and exercise your troubleshooting skills.
