CCNA Semester 3 - Skills Based Final Exam - Student Training Instructor 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) Router Configuration and 2) Troubleshooting and 3) Network Concepts. All 3 parts should be completed (total possible of 100 points) and the total score combined with the Semester 3 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 based on their classroom environment and schedule. Emphasis should be on the hands-on portion of 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 groups (teams) of four. Try to ensure that teams are evenly matched with a variety of skill levels. Teams should be formed about 2/3 of the way through the class to allow them time to work together and to minimize team dropout. Hand out page one (only) of exam Part 1 from the exam copy when teams are formed to allow adequate preparation for the exam. Part 1 will require access to one router per student. Four students can be tested simultaneously on Parts 1 and 2 (if 6 routers are available) while another group is working on Part 3 Network Concepts portion of the exam. Exam Part 1 – Router Configuration – (Practical hands-on, Max. time 40 min., 60 Points) Objective: Manually configure a router and an attached workstation for a school network with a WAN connection to the district office. The district office router is already configured and the IP addresses are given. The network subnet mask and the host range for an assigned subnet must be determined and an Access Control List (ACL) must be applied to block certain traffic from the school to the district office. Each student will configure one router and an attached workstation. Preparation / Tools: Standard 5-router / workstation lab setup plus one additional router if available. If 6 routers are available, 4 students can be tested simultaneously. If 5 routers are available, 3 students can be tested simultaneously. Workstations should have HyperTerminal and a TFTP server installed. Backups of the configuration files for all 5 (or 6) routers on floppy or CD should be available for quick restore. The configuration of the district office routers; DO1 and DO2 are included at the end of these guidelines. CCNA Semester 3 - Skills Based Final Exam - Student Training Instructor Guidelines - Exam Overview and Administration – Cont. Exam Part 2 - Troubleshooting – (Practical hands-on, Max. time 20 min., 20 Points.) Objective: Troubleshoot problems after the workstation and router have been configured. After the workstation and router are successfully configured, the individual will be asked to leave and problems will be introduced to demonstrate troubleshooting skills. Problems encountered during troubleshooting and the steps taken to correct them must be documented. Each student will have to troubleshoot the workstation and the router they configured. Preparation / Tools: Develop a list of 5 to 10 potential problems to be introduced. Problems should focus on OSI layers 3 and 4 resulting in loss of network connectivity or causing the ACL not to function correctly. Examples include: 1) Change workstation IP settings, 2) Change router IP / interface configuration, 3) Change the ACL statements, 4) Change the interface or remove the ACL from an interface on the router. 5) Change the routing protocol used. Exam Part 3 - Network Concepts – (Oral or Written, Est. time 20 min., 20 Points) Objective: Answer 2 networking concepts questions from a pool of approved questions. Any student may have to answer any question and should 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 which can be found in the instructor’s version of the Semester 3 curriculum in the Preface, Chapter 0 under Third Semester Finals. A Rubric is provided to help assess the accuracy and completeness of student’s answers. Semester 3 Skills Based Final – Part 1 Router Configuration Student Training Name: ___________________Date: ______________ Exam Part 1 Overview: You are the network administrator for a local elementary school. Your task is to setup and configure the router for your particular location. You must configure the router from the command line of the console interface using only IOS help. The district office routers, labeled DO1 and DO2, are already configured and their setup is given below. The district has decided to create 1024 subnets from class B network 171.17.0.0 to allow room for expansion. The district has also chosen to use IGRP for their routing protocol and has been assigned autonomous system number 139 by the ICANN. You will be assigned a Station Number for your school. This number is the same number as the usable subnet you are assigned to. For example, if you are station number 10, you will be assigned the 10 th usable subnet range from your district’s network. This is illustrated in the diagram by the letters SN and a number. For security purposes, all of the student workstations will be given the upper half of the available addresses in the host range of your school’s LAN. All of your major networking equipment (Routers, switches, servers, printers etc.) and faculty stations will be given the lower half of the available address within that same range. You will need to create and apply an access list that filters and denies the student’s stations TELNET access to the closest serial interface on the district router.
