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 straightwired 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.
Preparation / Tools: PC (Mac, Win 9x, NT or 2000) with access to a browser and Control Panel /
Network settings. Straight wired patch cable, hub or switch with router connected. 2514 Router
with IOS 12.0 attached to hub or switch and configured as indicated in the following instructor notes.
A list of potential problems and causes which can be found in the instructor’s version of the Semester
1 curriculum in the Preface, Chapter 0 under First Semester Finals.

Semester 1 Skills Based Final – Part 3 Network Connection

Router Configuration Instructor Notes Use the following configuration to set up the router for the skills test. 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
