CCNA 1 Skills-Based Final Exam

Exam Overview and Guidelines

The overall goal of this skills-based assessment is for the student to connect two PCs to create a small LAN using Ethernet and have the PCs communicate using IP. The student must demonstrate the ability to properly terminate a straight-through Ethernet patch cable and connect two PCs through a hub or switch. In addition, they must be able to create a subnet scheme and configure IP settings in order for the PCs to communicate. The exam consists of three parts: 1. Build and test a patch cable (You may use your cables from previous labs) 2. Calculate subnets 3. Cable and configure workstations All three parts must be completed for a possible total of 100 points. Students should be made aware of what they will be tested early on in the course in order to study and prepare adequately for the exam. The exam overview and guidelines portion can be handed out in advance to give them time to prepare.

Part 1 ­ Build and Test Cable

Estimated Time: 30 minutes Possible Score: 30 points

Objective

Build a straight-through Ethernet cable for connection of two PCs using a hub or switch. Test the cable with a cable tester for correct pinouts and continuity. Use Category 5 or 5e cable and T568A standards. This cable should be used in Part 3 of this exam.

Preparation / Tools

A length of Category 5 or 5e cable, two RJ-45 connectors, wire cutter and stripper tool, crimping tool, basic cable tester, Fluke LAN Cable Meter 620 or Fluke LinkRunner.

Part 2 ­ Subnet Calculation

Estimated Time: 30 minutes Possible Score: 30 points

Objective

Given a Class A, B, or C IP address, and specific requirements for the number of subnets, the student should be able to do the following: · · · · Determine the minimum number of bits to be borrowed Identify the subnet mask Identify the subnetwork address of a particular subnet Determine the range of addresses for a particular subnet

Preparation / Tools

Obtain subnet requirements from the instructor. Provide all subnet calculations in Part 2 of the exam. Use a separate piece of paper to show all your work. No computerized subnet calculation tools are permitted.

Part 3 - Workstation Configuration and Cabling

Estimated Time: 30 minutes Possible Score: 40 points

Objective

Connect two PCs to a hub or switch. Use two straight-through cables, one of them built in Part 1 of the exam. Configure the network settings for each PC. Specify the IP address, subnet mask, and default gateway based on the results from Part 2 of the exam. Use the command prompt or run a utility to display the IP configuration settings for each PC. Use the ping command to demonstrate connectivity between the PCs.

Preparation / Tools

· · Two PCs with Windows 9x, Me, NT, 2000, or XP installed. Two straight-through patch cables and a hub or a switch and connection to router (programmed by instructor)

Part 1 - Build and Test Cable (You may use cable from previous

labs.) Obtain a piece of Category 5 or 5e cable and two RJ-45 connectors. Use a crimping tool to attach the RJ-45 connectors to the cable. Wire the cable as a straightthrough using either the T568A or T568B standard as indicated below. Use a cable tester to verify that the cable is functional. Cable standard to be used: T568A _____ 1. Are the correct wires in the correct position on pins 1 thru 8? Note: Refer to the labs for colors and the correct pinout. _______ (10)

2. Is the sheathing inside the connector and untwisting within specs? _______ (10) Note: Sheathing should be inside and untwisted less than a 1/2 inch. 3. Does cable test OK with cable tester? _______ (10) Note: Lights should come on or the LCD readout should show continuity Part 1 Points Scored: _______ (30)

Part 2 - Subnet Calculation using Classful Addressing

Obtain the following Network address, subnet requirements and IP address information from the instructor. Host IP address: _______________________ Subnet mask: _______________________

Fill in the following blanks based on the above information (2 pts each). Major network information: 1. Network ID Class: (A, B, or C) _______ 2.
