A user notices that a laser printer is having paper jams after the paper reaches the transfer corona assembly. What piece of equipment could MOST LIKELY be malfunctioning that is causing a problem at this point?
Static-charge eliminator strip
The static-charge eliminator strip takes the transfer corona charge away from the paper. Without the strip, the charge may stay on the paper, causing it to stick to the EP cartridge.
A problem with the high-voltage power supply would result in the printer not powering on. A problem with the toner cartridge could result in blank pages. A problem with the EP drum could result in repetitive marks and defects in prints.

SATA
The image is of a SATA connector, commonly used for internal hard drives.
When a user loses connectivity to the network, what is the FIRST item to check?
Loose cable
When a user suddenly loses connectivity, it usually means a loose cable, especially if they are in an area that's well-traversed in the office. Check the cable that connects to the network card; it should have blinking link lights to indicate that it's connected.
NIC drivers would not likely be an issue unless the user has administrative access to the workstation. NIC cards do not need a separate power supply. A poor cable signal is less likely than a loose cable.
A user wants to print a large job on both the front and back sides of the paper.
Which of the following settings should the technician advise the user to change in the printer settings?
Duplex
What type of connectivity device is used to terminate network runs in a telecommunications closet?
Punchdown block
A punchdown block can be found in a telecommunications closet mounted on a networking rack. Network drops from work areas are terminated (punched down) in the back, and cables with RJ-45 connectors connect the front to a switch or router. Punchdown blocks provide a neat way to keep cables organized. Switches and routers are network connectivity devices. A terminator is another name for a terminating resistor, which is sometimes needed at the end of a length of coaxial cable.
What do you call a collection of circuits that provide both peripheral and interface functions for a processor?
Chipsets
A chipset is used as a way to describe the circuitry integrated on a motherboard. The chipset works in conjunction with the CPU to access and control all the components of the computer. For example, the CPU is connected to the Northbridge through the frontside bus. The Northridge and the Southbridge are integrated chips on the motherboard that connect to the various peripheral and hardware components such as RAM, PCIe, LAN, and more.
Expansion slots are slots that allow devices that expand a computer's functionality. A bus is a pathway that sends data between components. The Southbridge is a subset of a chipset.
A user prints their report out on an inkjet printer, but the lines of text are unevenly spaced. What should be replaced in the printer to fix this issue?
Stepper Motor
The stepper motor and the attached belt are responsible for movement of the print head. If the motor malfunctions, it can result in uneven lines or characters that are scrunched together.
Problems with the pickup roller could result in paper jams. Problems with a transformer could result in power issues. Problems with separator pads could result in paper-feeding problems.
An administrator comes across a cable with a connector that is square-shaped and requires releasing a latch to connect. What type of connector are they looking at?
SC
An SC (subscriber connector) is a type of fiber-optic connector. It is not as popular as the ST (straight tip) fiber-optic connectors. SCs require pressing a button to release the latch in order to be unplugged.
A Lucent connector (LC) uses a mini form factor (MFF). A straight-tip (ST) connector is round and uses a twist-and-lock attachment. An RJ-45 is the rectangular connector used for Ethernet LANs.
The common Ethernet standard for the 100BaseT over CAT-5 twisted-pair cable has a maximum speed of 100 Mbps and a maximum distance of how many meters?
100 meters
100BaseT over CAT-5 allows for 100 Mbps transfer rates, but it has a maximum distance of 100 meters before the signal suffers from degradation.
What should you do with an inkjet printer to ensure that the image on the screen is printed exactly the same on paper?
Calibrate the printer
Each printer driver installation lets you calibrate your printer to your PC monitor. This ensures that the image on the screen has the same colors and brightness as the image printed on paper.
The other answer choices are for laser printers.
Clean the rollers
Add more toner
Adjust tension on ribbon cables
A technician needs to recommend an internet connection for a customer who travels around the world and wants to have connectivity while visiting remote camping locations. Some of the locations the customer visits have limited or unreliable cellular service.
Satellite
After prints were coming out faded, a user added a brand new toner cartridge to a laser printer. Now, the pages are coming out completely blank. What is MOST LIKELY causing the problem?
Toner Catridge Sealing tape
Given the situation, the user most likely forgot to remove the sealing tape from the toner cartridge. The toner cartridge has sealing tape to keep the toner inside during shipping.
If the toner was just replaced, it would not be empty. A static-charge eliminator strip is something that should be worn around the wrists when working with computer components. An issue with the transfer corona assembly wouldn't have caused the faded pages.
A company needs to run a cable that supports 10 Gbps, runs for miles, is impervious to electrical interference, and cannot be wiretapped. Which type of cable should they run?
SMF Fiber
Single-mode fiber (SMF) can transmit for 10 Gbps for up to 25.85 miles. Fiber is also immune to electrical interference and wiretapping.
CAT-7 UTP is susceptible to interference. MMF fiber only runs for up to 300 meters. RG-6 coax can be wiretapped.
You are adding paper to a printer that uses tractor-feed paper, which requires lining the holes up with pins on the paper-forwarding mechanism. What type of printer are you maintaining?
Impact
An impact printer typically requires paper that always feeds at a consistent rate. To achieve this, the paper will have holes on the outside edges, which is fed into the printer using a tractor-feed mechanism. Thermal printers use special paper and heat to create images, whereas laser printers use the electrophotographic process. Inkjet printers spray drops of ink onto paper.
A company is looking for a service that will host popular software development tools for them in the cloud. The company does not want to manage the software or hardware themselves. Which type of cloud service would best suit their needs?
PaaS
Platform as a Service (PaaS) can include hosting software development tools in the cloud so that clients do not have to worry about maintaining them. That lets the client focus on building their app rather than worrying about the environment or hardware that the software development tools are hosted on.
Infrastructure as a Service (IaaS) lets a customer lease network resources that they can use as they wish. Software as a Service (SaaS) provides a single application over the cloud, such as file storage or a word processor. Business Processes as a Service (BPaaS) offers services specific for businesses, such as payroll and help desk support.

It won’t fit.
Feedback: DDR3 and DDR4 memory slots are both keyed, but the keys are in different places. DDR3 has 240 pins and DDR4 has 288 pins. Therefore, the memory will not fit into the slots on the motherboard.
How many lumens are typically required for a projector in an office where ambient light is reasonably controlled, meaning that outside light is filtered and lights inside the room can be dimmed?
2,500
2,500 lumens is considered a low, but acceptable, illumination for an office setting when the ambient light is under control. It's recommended for projectors located in a medium-sized room where lighting is controlled.
In some settings, a higher level of lumens is required, such as 5,000 to 6,000
An engineer is experiencing unexpected reboots on a graphics workstation when rendering complex 3-D models. The workstation is configured with a 115V power supply that is rated at 200W and connected to a UPS. The central processing unit contains 16 hyperthreaded cores, and a discrete graphics solution utilizing an 8-pin power connector is installed in a PCI Express x16 slot. Which of the following indicates where the technician should begin troubleshooting?
The power supply, as 200W is insufficient when the GPU is heavily tasked
A user is experiencing multiple paper jams with an inkjet printer. What two things could be contributing to this?
Worn pickup roller or wrong paper type
If the pickup roller is worn down, it won't have enough friction to push the paper through the printer correctly. Likewise, if the paper is too smooth, it won't create enough friction to move properly.
A broken stepper motor would have trouble moving the print head carriage. A blown transformer would not power up the printer. An empty ink cartridge would result in blank pages.
The gaming industry has pushed forward much of today's current computer technology. Which of the following is generally the preferred expansion slot of gamers?
PCie
PCIe is the preferred choice for gamers due to its extremely high bit-rate ability. It offers gigabit-per-second transfer rates. With additional technologies such as the ATI CrossFire and NVidia SLI, you can incorporate several PCIe graphics cards into one computer for massive graphical capabilities.
PCI and AGP are expansion slot types with outdated technologies. A communications and network riser (CNR) slot is an outdated slot for networking, audio, and telephony.
If nothing appears on the screen when the computer is turned on, what would be a good first step to take?
Check cabling
The computer does a hardware check before booting the operating system. Always check what's easier first, such as the cabling on the hard drive and monitor. Also, ensure that the cables are inserted properly to avoid boot issues. In instances where there is no video, ensure that all cables are firmly inserted into the monitor and video ports on the computer.
Heat issues would not immediately affect the display. Trying a new monitor should be tried after checking the cables. Brightness levels should not go completely dark
An impact printer prints garbled characters. What could be the cause of this?
Bad printer control board
A bad printer control board can lead to a printer printing garbled characters. The printer control board should be replaced in this situation.
A worn out printer ribbon would result in faded characters being printed. A loose print head cable would result in small blank lines going through the print occasionally. A printer head pin that is stuck would result in dark lines going through the print.
Which of the following socket types is made for Intel-based processors?
LGA 1200
Any socket type labeled with LGA is Intel-based. Since the socket will vary depending on the motherboard design, you need to know the socket type on a motherboard to identify which CPU you can install. This is very important because the sockets are not universal but rather specific.
The other answer choices are for AMD processors. Socket TR4, AM4, FM2
An administrator wants to determine if a user's network card is working properly. What device can they use with the network card to see if it can send and receive data properly?

A technician is implementing a SOHO wireless solution with three access points. Which of the following actions would avoid high latency?
Configuring all devices with different channels
A user reports that they cannot access any network resources. The result of running the ipconfig command shows an IP address that starts with 169.254.x.x. What could be causing the problem?
DHCP Server
An address that starts with 169.254.x.x is an APIPA address, which is assigned if the computer cannot receive an address from a DHCP server. To fix this, find out why the DHCP server is not assigning addresses.
A problem with a DNS server would result in the inability to use domain names to contact servers while contacting by IP address would still work. A problem with an FTP server would result in only file transfers not working. A problem with an SSH server would result in not being able to make encrypted terminal connections to a server.
Several users who share a multifunction printer in an office have reported unintended, thin, vertical lines that cover the entire height of every page printed from the printer.
Perform the drum-cleaning procedure.
Which of these has its communication managed by the Southbridge subset of the chipset?
PCI
The Southbridge is used with virtually all peripherals. Modern motherboards typically come with integrated ports such as PS/2, LAN, USB, audio digital/analog, and FireWire ports that fall under the jurisdiction of the Southbridge.
The AGP slot, RAM, and CPU are all connected to the Northbridge.
