Hardware and Network Troubleshooting 6

Within the last five minutes, several users in one part of the building have called in to report that they have lost their network connection. The connection had been working earlier in the day. What is most likely the cause of the problem?

• Faulty network card drivers

• Incorrect TCP/IP configuration

• Bad network cable

• Faulty switch

A user reports that they cannot see their network shares or email, or even connect to the printer, but local applications are working fine. You ask what has changed since the last access, and the user mentions cleaning their desk. What might be the problem?

• The user might not have logged in.

• The printer, email, and file server could be offline.

• The network cable may not be connected.

• The Group Policy was reconfigured.

During a meeting, the manager mentions the projector has been problematic since the start of the meeting. They tried running the projector from a few laptops with no success. Multiple pop-ups were occurring, but it's unknown what the pop-up windows reported. What might be your next step?

• Open the log for information on failed jobs.

• Check the light source for failure.

• Verify that cables were attached.

• Allow the projector to cool down and try again.

A user reports the wireless Internet connection will randomly shut down in the afternoon. You check the Internet router by the window to find it still has power. What is the most likely cause of this problem?

• Network overloaded

• Printer queue full

• Wireless router overheating

• Workstation requires patching

A technician is troubleshooting a suspected hard drive issue. They are following the troubleshooting methodology. As part of identifying the problem, what should they do?

• If necessary, conduct external or internal research based on symptoms.

• Question the user and identify user changes to the computer.

• Document findings, actions, and outcomes.

• Determine next steps to resolve the problem.

A billing clerk just moved from their normal office out to a new office separated from the loading dock by a cement block wall. The shipping clerk on the loading dock doesn't have a problem with wireless connectivity, but the billing clerk can't get reception in their new office. When they step out onto the loading dock, their laptop works just fine. Why are they losing connectivity in their office?

• They're too far from the WAP.

• The cement walls block the signal.

• The shipping clerk's PC interferes with the signal.

• The billing clerk accidentally turned their Wi-Fi off.

Your spouse just began working from home. They've decided that they like to work on the kitchen island, so they moved the router into the kitchen to get a better signal. Now the Wi-Fi connection gets dropped periodically no matter where they are in the home. What is going on?

• Your service provider is limiting the bandwidth.

• The router is old and needs replacing.

• The motors in the kitchen appliances are interfering with the Wi-Fi signal.

• Your spouse needs a better laptop to work from home.

You've moved to a new two-story townhouse and are trying to decide where to put your router. The townhouse is a rather open concept with the dining room near its center. Which of the following options would be best?

• On a stand in the corner of the dining room.

• Next to the metal staircase, so they'll be a good signal upstairs.

• Hide it behind the sofa.

• Set it on a sunny windowsill to reflect the signal back in.

Your friend dropped their iPad and it landed on its corner, on a rock. Now the screen has three large cracks from the corner radiating outward.

• Recycle it and get a new one.

• If possible, back up the device.

• The digitizer and glass need replacing.

• The display assembly needs replacing.

You are troubleshooting a difficult network connectivity problem. You have tested your theory to determine cause and found that you were wrong. According to troubleshooting theory, you have two choices for next steps. What are they? (Choose two.)

• Tell the user that the problem has been fixed, and document it as such.

• Verify full system functionality and document findings, actions, and outcomes.

• Escalate the issue.

• Establish a new theory of probable cause.
