CCNA 1 Skills-Based Final Exam – Option 1 Solution 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 2. Calculate subnets 3. Cable and configure workstations All three parts must be completed for a possible total of 100 points. Scores from the online final exam, module exams, completed labs, participation, and attendance can be combined with the grade for this skills-based exam to yield the final course grade. 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 overview and guidelines portion can be handed out in advance to give the students time to prepare.
Part 1 – Build and Test Cable Estimated Time: 15 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 or T568B standards. This cable should be used in Part 3 of this exam. At the start of the exam, the instructor will indicate which one of the two standards to use.
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.
