Scenario Requiring Understanding of Multiple Concepts
A 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.Slide11

Suppose
this NIC has failed.
Replacement NICs are not
available for
and no

Step 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.

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.Slide22
