- Which of the following has the fastest data throughput?
CD-ROM
Hard Drive
RAM
USB
RAM
Explanation: RAM is much faster than the rest of the options listed. For instance, if you have PC4-25600 DDR4 RAM (aka DDR4-3200), your peak transfer rate is 25,600 MB/s.
Incorrect answers: The rest of the devices in the incorrect answers are listed in descending order of data throughput: Hard drive: for example, 600 MB/s for SATA 3.0, 1969 MB/s for SATA Express, and 3500 MB/s for typical M.2 drives. M.2 is very fast but still a fraction of RAM speeds (as of the writing of this book in 2019). USB: for example, 5 Gbps for version 3.0 and 20 Gbps for version 3.2 (which equates to 2.5 GB/s) CD-ROM (typically 7.5 MB/s).

- You are configuring Bob’s computer to access the Internet. Which of the following are required? (Select All That Apply)
DNS Server Address Gateway Address Email Server Name DHCP Server Address Domain Name
DNS Server Address
Gateway Address
Explanation: To get on the Internet, the DNS server address is required so that the computer can get the resolved IP addresses from the domain names that are typed in. The gateway address is necessary to get outside the network.
Incorrect answers: Email server information is not necessary if the person is just looking to get on the Internet. A DHCP server address is not necessary either; however, it is an easier method. The beauty of DHCP is that you don’t need to know the DHCP server’s address to acquire an IP address. The domain name for your network is normally not needed, either; it is necessary only if you want to add the computer to the organization’s domain.

- You just configured the IP Address 192.168.0.105 in Windows. When you press the Tab Key, Windows automatically configures the Default Subnet Mask of 255.255.255.0. Which of the following IP Addresses is a suitable gateway address?
- 168.1.100
- 168.1.1
- 168.10.1
- 168.0.1
192.168.0.1
Explanation: 192.168.0.1 is the only suitable gateway address. Remember that the gateway address must be on the same network as the computer. In this case, the network is 192.168.0, as defined by the 255.255.255.0 subnet mask.
Incorrect answers: 192.168.1.100 is on the 192.168.1.0 network; so is 192.168.1.1. 192.168.10.1 is on the 192.168.10.0 network. Don’t forget that a zero at the end of an IP address denotes the network number.

- Special paper is needed to print on which type of printer?
Impact Thermal Laser Inkjet 3D
Thermal
Explanation: Regular paper can be used on all the listed printers except for thermal printers, which use specially coated paper that is heated to create the image.
Incorrect answers: A dot-matrix printer might use tractor-feed paper, but that is standard for many impact printers; it is also still considered regular paper. A laser printer or dot-matrix printer might use two-part paper, but two-part paper isn’t necessary for laser printers or dot-matrix printers to operate; thermal printers won’t work unless you use specially coated paper. Inkjet printers normally use standard copy paper for printing. Finally, 3D printers use a plastic filament, not paper.

- Which environmental issue affects a thermal printer the most?
Moisture
ESD
Dirt
Heat
Heat
Explanation: Heat is the number-one enemy to a thermal printer. Keeping a thermal printer or the thermal paper in a location where the temperature is too high could cause failure of the printer and damage to the paper.
Incorrect answers: Excessive moisture can cause rubber rollers and separation pads to fail over time, especially in laser printers. Electrostatic discharge (ESD) is always a foe, but only if you are working inside the printer. Dirt can clog up the works over time in any device. But by far, heat is what you have to watch for with thermal printers.

- Which of the following steps enables you to take control of a network printer from a remote computer?
Installing the Printer locally and accessing the Sharing Tab
Installing the Printer locally and accessing the spool settings.
Installing the Printer locally and accessing the Ports tab.
Connecting to the Printer via FTP
Installing the Printer locally and accessing the Ports tab.
Explanation: After you install the driver for the printer locally, you can then take control of it by going to the properties of the printer and accessing the Ports tab. Then click the Add Port button and select the Standard TCP/IP Port option. You have to know the IP address of the printer or the computer that the printer is connected to.
Incorrect answers: The Sharing tab enables you to share the printer so that remote users can use it; however, the remote user would then somehow have to connect to the printer. The spool settings can be set so that the computer spools documents before sending pages to the printer, which helps with less powerful printers and printer congestion. Some printers can be accessed via FTP, but usually they are controlled and accessed in another way. Either way, making a connection to the printer is not taking control of the printer.

- A Color laser printer produces images that are tinted blue. Which of the following steps should you perform to address this problem?
Clean the Toner Cartridge
Calibrate the Printer
Change the Fusing Assembly
Clean the Primary Corona
Calibrate the Printer
Explanation: After you install a printer, it is important to calibrate it for color and orientation, especially if you are installing a color laser printer or an inkjet printer. These calibration tools are usually built in to the printer’s software and can be accessed from Windows, or you can access them from the printer’s display.
Incorrect answers: If a toner cartridge needs to be cleaned, it probably has a leak and should be replaced. The fusing assembly needs to be changed only when it fails. Many printers will indicate when the fuser is at 20 percent life and needs to be replaced soon. If the fuser fails, the toner will fail to stick to the paper. The primary corona wire can be cleaned; it is near the drum. Cleaning it can help with other types of print quality problems, such as lines and smearing, though on many printers this is not necessary.
