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.

CCNA 1 Skills-Based Final Exam 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) St. Lawrence College - Comp11 Page 2 11/24/2003 CCNA 1: Networking Basics v3.0 – Skills-Based Assessment Copyright © 2003, Cisco Systems, Inc. CCNA 1 Skills-Based Final Exam Name: _______________________ Date: __________ Instructor: Parisien 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.
