Question 1

A small company's local area network has grown to the point where assigning IP addresses and other NIC parameters statically is no longer possible. What actions can a network administrator take to make network interface card configuration easier?

Accepted Answer

Incorporate a DHCP Server into the network.

Answer

A DHCP (Dynamic Host Configuration Protocol) server automates the process of assigning IP addresses and other network configuration parameters to devices on a network. This eliminates the need for manual static configuration, making network management much easier and more scalable for growing networks.

Question 2

A PC has been set up as a print server that will be accessible at all times. When the computer is not in use, it should be turned off to save energy. When a print job is received, what feature of the Network Interface Card allows a shut down or sleeping PC to wake up?

Accepted Answer

Wake-on-LAN

Answer

Wake-on-LAN (WoL) is a network standard that allows a computer to be turned on or woken up by a network message, often called a 'magic packet.' This feature is implemented in the Network Interface Card (NIC) and BIOS/UEFI settings, enabling the PC to listen for this specific packet even when powered off or in a low-power state. For a print server that needs to be accessible on demand without being constantly on, WoL allows it to wake up only when a print job is received, saving energy.

Question 3

A client complains that his laptop takes an excessive amount of time to boot up. You have a feeling he has a lot of processes running during startup. On a Windows 10 laptop, what utility would you use to view which processes are running?

Accepted Answer

Task Manager

Answer

Task Manager is a built-in Windows utility that provides comprehensive information about processes, applications, performance, and startup items. To view which processes are running during startup on a Windows 10 laptop, you would navigate to the 'Startup' tab within Task Manager. This tab lists all applications configured to launch automatically when Windows starts, allowing you to identify and disable unnecessary programs that contribute to slow boot times.

Question 4

A user notices that her hard drive is running out of capacity and decides to upgrade to a larger drive. She wants to delete all temporary files from her hard disk till then. What utility should she use to accomplish this?

Accepted Answer

Disk cleanup

Answer

Disk Cleanup is a utility built into Windows operating systems designed to free up disk space by identifying and removing various types of unnecessary files. These files typically include temporary internet files, temporary application files, system error memory dump files, and contents of the Recycle Bin. Running Disk Cleanup helps users quickly reclaim storage capacity and improve system performance by eliminating accumulated clutter.

Question 5

To create a new directory, a user uses the Windows command prompt. What command should you use to accomplish this?

Accepted Answer

MD

Answer

In the Windows command prompt, the `MD` command, which stands for 'Make Directory,' is used to create a new directory or folder. For example, typing `MD MyNewFolder` would create a directory named 'MyNewFolder' in the current working directory. This command is fundamental for organizing files and structuring the file system directly from the command-line interface.
