You are the desktop engineer for your company. A user named John reports that he cannot connect his computer to the office Ethernet local area network (LAN). To troubleshoot the problem, you check to confirm that the network cable is attached properly from both port and computer end. The network cable is connected properly. What should you do next?

1. Check whether the link light on the NIC is on.
2. Check whether the NIC is seated properly in the motherboard.
3. Check whether the installed NIC is compatible with the computer.
4. Check whether the correct driver for the NIC is installed on the computer.

Answer:

A. Check whether the link light on the NIC is on.

Tutorial:

Before performing any of the other given troubleshooting steps, you must check whether the link light on the network interface card (NIC) is on. If the link light is on, it indicates that the connection between the NIC and the network exists. If the link light is off, it indicates that there is a problem with either the cable or the NIC.

After checking the link light status, you can perform other troubleshooting steps, such as checking whether the NIC is seated on the motherboard slot properly or whether the NIC is compatible with the computer. You can also check whether the correct driver for the NIC is installed.

What is the most recent software from Microsoft that helps you protect your computer from malware and spyware threats?

1. Microsoft Windows Malicious Software Removal Tool.
2. Windows Defender.
3. Microsoft AntiSpyware.
4. Ad-Aware SE Personal.

Answer:

B. Windows Defender.

Tutorial:

Windows Defender is the most recent software from Microsoft that helps you protect your computer from malware and spyware threats. Windows Defender is free software from Microsoft that protects your computer against pop-ups, slow performance and security threats caused by spyware and other potentially unwanted software.

You can use Windows Defender to remove and quarantine spyware on Windows XP, Windows Server 2003 and Windows Vista operating systems. Spyware and malware are malicious software that threaten the security and privacy of computer users. Spyware and malware are installed on a computer through deceit or trickery without a user's knowledge or consent. This type of spyware and malware can range from unwanted pop-up ads to programs that can record keystrokes or take over a computer. The best method to help prevent spyware and malware threats is to inform user about the risks involved and how to avoid these risks.

Microsoft Windows Malicious Software Removal Tool is not the most recent software from Microsoft that helps you protect your computer from malware and spyware threats. Microsoft Windows Malicious Software Removal Tool helps you remove specific, prevalent malicious software from computers that are running Microsoft Windows Server 2003, Microsoft Windows XP or Microsoft Windows 2000. However, this tool does not protect your computer from spyware and malware in real time. This tool searches your computer for malware and spyware only when you run it.

Microsoft AntiSpyware also is not the most recent software from Microsoft that helps you protect your computer from malware and spyware threats. Microsoft AntiSpyware is the previous version of Microsoft Defender.

Ad-Aware SE Personal is a free anti-spyware software from Lavasoft that provides you with advanced protection against spyware and malware. Ad-Aware SE Personal is not a Microsoft product.
