SELF-PACED LEARNING


TEACH CONCEPTS, NOT ANSWERSA+ 901/902 Objectives Expect Conceptual Knowledge

• “Given a scenario…”• “Compare and contrast…”• “Summarize and explain…”


TEACH CONCEPTS, NOT ANSWERSTypical Questions to Check for Factual Knowledge

• What is the maximum segment length for a 100BaseTX cable?

• What is the maximum speed of 100BaseTX Ethernet?• What is the maximum segment length for 100BaseFL

multimode fiber?• What is the cause of attenuation in network cabling?


TEACH CONCEPTS EXAMPLE #1Scenario Requiring Understanding of Multiple ConceptsA client has contacted you to assist in resolving an issue with their network. The onsite technician has received numerous calls from users in the shipping department complaining that the network connection for all of the shipping computers is dropping intermittently. The technician has checked the CAT5e cable currently installed between the office space network closet and the switch in the shipping department and found it is wired correctly. The technician does not want to relocate any network hardware, is content with Fast Ethernet speeds, and has no plans for future network growth.

Refer to the following floorplan and explain your recommendation to solve the network issue while being careful to meet the requirements of the client. Be sure to include detailed specifications for any changes you recommend.


TEACH CONCEPTS EXAMPLE #1


TEACH CONCEPTS EXAMPLE #2Use Diagram 1 to verify you have received valid IP configuration values. Do the values on your lab computer match the values on the diagram?


INVESTIGATE & DISCOVERSuccessful Discovery Learning Requires:

• Resources and Tools for Student to Discover Solutions• Clear Objectives and Expectations• Instructor Assistance, One-on-One or Small Groups• Instructor Check for Understanding• Answer Students Questions with Probing Questions

o Drive the Student Back to Resourceso Help Student Connect Concepts


DISCOVERY LEARNING EXAMPLE #1For this lab you will need:

The knowledge you gained from Labsim 8.2, textbook Ch 24 Notebook computer and power adapter (see your instructor) Antistatic precautions Jewelers screwdriver set

Step 1 Before beginning any type of upgrade or repair of a notebook computer several factors must be taken into consideration.

a. What is the first step in repairing a notebook computer when you are unsure how to disassemble the computer? Why is this step important?

b. You completed the first step as defined above. Before you take the first screw out of a notebook computer, what is the next step you should take after powering down the computer?


DISCOVERY LEARNING EXAMPLE #2a. Remove the wireless NIC.

- What expansion bus interface is used on this wireless NIC?

- You should have disconnected a white and black wire from the wireless NIC. What do these wires connect to (opposite the NIC)?

- What would be the outcome if you forgot to reattach these wires when you reassembled the computer?

- Suppose this NIC has failed. Replacement NICs are not available for and no used NICs can be found anywhere. How might you get the computer connected to the wireless LAN so the user can continue working?


LABS, EXERCISES, & SCENARIOSHands-on Learning Must:

• Be Practical & Applicable to Real-World• Be Challenging & Comprehensive• Follow the Same Investigate & Discover Principles (not step-

by-step)• Promote Collaboration & Teamwork• Have Multiple Instructor Sign-off Points

o Check for Understanding


HANDS-ON EXAMPLE #1Using Diagram 1, manually configure your lab computer’s IP configuration settings to connect to the lab network without using DHCP.If the IP configuration parameters are configured correctly, you should be able to open a Web browser and navigate to http://mailserver.localTry it. Can you reach this URL?


HANDS-ON EXAMPLE #1If you do not have access to a physical or virtual machine, use a screenshot for the student to fill-in.

Using Diagram 1 and the following screenshot, manually configure the lab computer’s IP configuration settings to connect to the lab network without using DHCP.


HANDS-ON EXAMPLE #2Configure the host with the parameters that meet the following requirements.Subnet: 10.0.0.0IP address: Last valid address in subnetSubnet mask: Default class subnet maskDefault gateway: First valid address in subnetPreferred DNS server: Last valid address in the 192.11.2.0 subnet Alternate DNS server: First valid address in the 199.255.0.0 subnet


HANDS-ON EXAMPLE #3Step 2 Many times, when a computer is infected with malware or while you are in the process of cleaning a computer of malware, the explorer.exe process gets halted. This can cause some rather ugly things to happen. Let’s make something ugly happen and then make things beautiful again.

a. Using the tool you documented in Step 1, kill the explorer.exe process.Close the tool you documented in Step 1. Write your observations of what happened.


HANDS-ON EXAMPLE #3b. Now that’s ugly. The Start orb or Start Menu button is gone. The

tool you documented in Step 1 is gone. The screen is blank. Now what? How can we resolve this issue without restarting the computer?

Resolve this issue using the tool you documented in Step 1.

Write your observations of what happened.

Be prepared to show these steps to your instructor.


HANDS-ON EXAMPLE #4STOP: You must show this lab and your configuration to your instructor before continuing. Have your instructor sign here.____________


TROUBLESHOOTING EXAMPLE #1Step 1 A user is complaining about the print quality of their inkjet printer. When you arrive at the customer’s location to check the printer, you print a page that looks similar to the following figure.


TROUBLESHOOTING EXAMPLE #1a. Using the Canon Inkjet printer you installed while doing Lab 7.2.1,

locate the process you would use to print this page.

b. What test print did you select to print this test page?

c. What is the first thing you should do to the printer to attempt to clean-up this test print?

d. If this first process did not resolve the issue, what would you do next?

e. If the first and second process did not resolve the issue, what would you do next?


TROUBLESHOOTING DECISION TREE Number Problem Next Step

1.0 Problems with the monitor

1.1 Monitor is turned off Check the LED light on front of monitor.

1.2 No power to monitor Plug power to monitor into a different outlet.

1.3 Monitor needs adjusting Adjust buttons on front of monitor.

1.4 Hardware problem with monitor Exchange monitor for a known good one.

1.5 For CRT monitor, EMI interference Press degauss button or remove interference.


Number Problem Next Step

10.0 Problems with Windows system files and device drivers

10.1 NIC drivers are corrupted or out of date Update the NIC drivers

10.2 System files are corrupted, but can still boot to Windows desktop Run the System File Checker utility

10.3 Recent changes to the system are causing a problem Apply a restore point.

10.4 Corrupted system files; unable to boot to desktop Boot from a DVD and repair the system.

10.5 Windows is locked or generally giving trouble Restart Windows

10.6 Video drivers are corrupted Enable low-resolution video (640x480)

10.7 Windows errors resulted in the BSOD View logs available in Event Viewer

10.8 Corrupted registry is affecting Windows 7 startup Boot using the Last Known Good Configuration
