CCNA Semester 1 - Skills Based Final Exam - Student Training Guidelines - Exam Overview and Administration This exam is for use with regular CCNA classes taught by local academies to high school and college students. The skills-based exam consists of three parts; 1) Cable Build and Test, 2) Network Concepts and 3) Network Connection. All three should be completed (total possible of 100 points) and the total score combined with the Semester 1 online assessment exam to establish a course grade. Scores from chapter exams and completion of labs as well as points for participation and attendance may also count toward the final grade. The guidelines presented here are recommendations and instructors have flexibility in assigning point values and administering the exam. Students should be made aware of what they will be tested on early in the course in order to study and prepare adequately for the exam. The exam may be administered by dividing the class into three groups with each group starting on a different part of the exam and then rotating as they complete each portion. Exam Part 1 – Cable Build / Test – (Practical hands-on, Est. time 25 min., 20 Points) Objective: Build a straight–wired Ethernet cable for connection of a PC to a hub or switch and test it with a basic cable tester for correct pinouts and continuity. The cable should be CAT 5 and wired to the T568A or B standards. Length will vary depending on physical conditions. This cable may be used to connect the PC to the hub or switch used in Part 3 of this exam. Preparation / Tools: Length of CAT 5 cable, (2) RJ45 connectors, Wire cutter/Stripper tool, Crimping tool, Basic cable tester or Fluke LAN Cable meter 620. Exam Part 2 - Network Concepts – (Oral or Written, Est. time 25 min., 30 Points) Objective: Answer 3 networking concepts questions from a pool of approved questions. Any student may have to answer any question and will know the questions ahead of time. Responses may be given verbally to the instructor / proctor or written depending on instructor and student preferences. Preparation / Tools: List of questions and rubric for assessment. These are found in the instructor’s version of the Semester 1 curriculum in the Preface, Chapter 0 under First Semester Finals. Rubrics are also provided to help assess the accuracy and completeness of student’s answers. Exam Part 3 - Network Connection – (Practical hands-on, Est. time 25 min., 40 Points) Objective: Connect a PC to a LAN and configure the IP network settings for attachment to an Ethernet hub or switch that is attached to a router. Determine the subnet mask and host range given the number of bits borrowed and the subnet number used. Demonstrate connectivity by pinging the router and opening a web page on it. When the PC is successfully connected to the LAN, problems will be introduced into the PC and/or network to demonstrate troubleshooting skills. Document the problems encountered during troubleshooting and the steps taken to correct them.

After the PC is successfully connected to the network, the student should leave and the instructor will introduce problems into the PC or network which must be resolved and documented in the space provided. Include the following: symptoms, causes, details of tests done, detailed problem results (from layer 1 testing), detailed solutions. Instructor notes: A list of potential problems and causes can be found in the instructor’s version of the Semester 1 curriculum in the Preface, Chapter 0 under First Semester Finals. Each student should be assigned a workstation number that will become the useable subnet # with which they perform this assessment. Make sure each student has an appropriate assigned subnet number before starting. Router configuration allows all workstations to maintain connectivity so that you may test a class of up to 30 students simultaneously depending on your classroom environment. Refer to the router configuration at the end of the instructor guidelines to set up the router. Students must have the ability to alter the IP network settings on their workstations. Students will be using a class C network 193.5.5.0 which is divided into subnets by borrowing 5 bits from the network portion of the address. The subnet number assigned is the same usable subnet (1 st , 2 nd 3 rd etc.) as their workstation number. The proctor must initial each step. The following example uses workstation / subnet 2.

Use a 2514 router with 2 Ethernet interfaces. ! Both interfaces e1 and e0 need to be connected to the hub. Router password is: skills1. Router IOS should be at least version 11.2 but preferably version 12. Students will be prompted for a password when accessing the router through the browser. This indicates successful completion of the connectivity portion of the Sem 1 skills based assessment. You may disable the password on the router if you wish for your students to see the web based interface. (WARNING: this allows the students access to the router configuration) Therefore, you may wish to wait until after testing is complete to disable the password and show the web-based interface as a demo instead. The following router configuration may be 1) keyed in manually at the router console, 2) entered via the SETUP utility or 3) uploaded using the HyperTerminal Transfer / Send Text File option. Prior to configuring the router, erase the existing startup configuration file. Router> enable (Enter current enable password) Router# erase start (Erases startup configuration file) Router# reload (Don’t save the existing configuration and let the router reload Refer to semester 2 labs for the procedures for loading the configuration file from a tftp server or from HyperTerminal. After the router reboots, you may use the default setup mode or enter config mode with the following command. Router# config t Router configuration commands for Semester 1 Skill-based exam Router IOS Command Purpose / Function ip http server Enables the web server function Enable secret skills1 Sets secret password to skills1 router rip Enables RIP routing protocol service network 152.20.0.0 Enables RIP advertisements to be broadcast and received for network 152.20.0.0 (on interface E1) network 193.5.5.0 Enables RIP advertisements to be broadcast and received for network 193.5.5.0 (on interface E0) int e0 Selects interface E0 for configuration ip address 193.5.5.1 255.255.255.0 Sets IP address and subnet mask for E0 no shutdown Brings up interfaces E0 int e1 Selects interface E1 for configuration ip address 152.20.71.237 255.255.0.0 Sets IP address and subnet mask for E1 no shutdown Brings up interfaces E1 Copy the new running configuration to the startup NVRAM with the following command.
