CCNA Exploration Network Fundamentals

Exploration Network Fundamentals : Skills Based Final Option 1

Scenario In this Skills Based Assessment students will create a small network that requires connecting network devices and configuring host computers and one Cisco router for basic network connectivity. Subnet A and Subnet B are subnets that are currently needed. Subnet C and Subnet D are anticipated subnets, not yet connected to the network. The 0th subnet will be used. Switch1 has a default configuration, and does not require additional configuration. Common utility commands will be used to test and document the network.

Task 1: Design the Logical LAN Topology. Total points: 35 Time: 20 minutes. Given an IP address and mask of 168.78.192.0 /21 (address / mask), design an IP addressing scheme that satisfies the following requirements: Subnet Subnet A Subnet B Subnet C Subnet D

Number of Hosts 257 103 61 954

The 0th subnet is used. No subnet calculators may be used. All work must be shown on the reverse of this Final. Subnet A Student Specification Input Number of bits in the subnet 23 IP mask (binary) 11111111.11111111.11111110.00000000 New IP mask (decimal) 255.255.254.0 Maximum number of usable 30 subnets (including the 0th subnet) Number of usable hosts per 510 subnet IP Subnet 168.78.196.0 First IP Host address 168.78.196.1 Last IP Host address 168.78.197.254

Points (6 points)

Subnet B Student Specification Input Number of bits in the subnet 25 IP mask (binary) 11111111.11111111.11111111.10000000 New IP mask (decimal) 255.255.255.128 Maximum number of usable 116 subnets (including the 0th subnet) Number of usable hosts per 126 subnet IP Subnet 168.78.198.0 First IP Host address 168.78.198.1 Last IP Host address 168.78.198.126

Subnet C Student Specification Input Number of bits in the subnet 26 IP mask (binary) 11111111.11111111.11111111.11000000 New IP mask (decimal) 255.255.255.192 Maximum number of usable 230 subnets (including the 0th subnet) Number of usable hosts per 62 subnet IP Subnet 168.78.198.128 First IP Host address 168.78.198.129 Last IP Host address 168.78.198.190

Points (6 points)

Subnet D Student Specification Input Number of bits in the subnet 22 IP mask (binary) 11111111.11111111.11111100.00000000 New IP mask (decimal) 255.255.252.0 Maximum number of usable 16 subnets (including the 0th subnet) Number of usable hosts per 1022 subnet 168.78.192.0 /22 IP Subnet First IP Host address 168.78.192.1 Last IP Host address 168.78.195.254

Points (6 points)

Host computers will use the first IP address in the subnet. The network router will use the LAST network host address. Write down the IP address information for each device: Device Host1 Router1-Fa0/0 Host2

IP address 168.78.196.1

Router1-Fa0/1

168.78.198.126

168.78.197.254 168.78.198.1

Mask

255.255.254.0 255.255.254.0 255.255.255.12 8 255.255.255.12 8

Gateway 168.78.197.254 ------------168.78.198.126

Points (11 points)

-------------

Task 2: Configure the Physical Topology. Total points: 15 Time: 5 minutes. Step 1: Physically connect lab devices.

Figure 1. Cabling the network. Cable the network devices as shown in Figure 1. If not already enabled, turn power on to all devices. Step 2: Visually inspect network connections. After cabling the network devices, take a moment to verify the connections. Correct Cabling LAN cable between Host1 and Router1 Fa0/0 LAN cable between Switch1 and Router1 Fa0/1 LAN cable between Switch1 and Host2 Console cable between Host1 and Router1

Task 4: Verify Network Connectivity. Total points: 20 Time: 15 minutes. Step 1: Use the ping command to verify network connectivity. Network connectivity can be verified with the ping command. **NOTE: If pings to host computers fail, temporarily disable the computer firewall and retest. To disable a Windows firewall, select Start | Control Panel | Windows Firewall, select OFF, and OK. Use the following table to methodically verify connectivity with each network device. Take corrective action to establish connectivity if a test fails:

In addition to the ping command, what other Windows command is useful in displaying network delay and breaks in the path to the destination? Answer: _______(4 points) Instructor Sign-off Task 4: ______________________ Points: _________ of 20

Task 5: Cleanup NOTE: DO NOT PROCEED WITH CLEANUP UNTIL YOUR INSTRUCTOR HAS GRADED YOUR SKILLS BASED FINAL AND HAS INFORMED YOU THAT YOU MAY BEGIN CLEANUP. Unless directed otherwise by the instructor, restore host computer network connectivity, then turn off power to the host computers. Before turning off power to the router and switch, remove the NVRAM configuration file (if saved) from Router1 with the privileged exec command erase startup-config. Disconnect and neatly put away all LAN cables that were used in the Final. Remove anything that was brought into the lab, and leave the room ready for the next class.
