Test Prep 1 Flashcards
What is a tool that would allow you to easily identify a network cable that was not labeled in the wiring closet during its installation?
Cable Tester
Punchdown Tool
Multimeter
Tone Generator and Probe
Tone Generator and Probe (Fox and Hound)
EXPLANATION:
A Tone Generator and Toner Probe is an excellent tool that allows you to easily detect which cable goes to which port on a Patch Panel in a Wiring Closet. While you could use a Cable Tester (If both ends of the Cable were available to the tech), a Tone Generator and Probe are much more efficient at identifying cables that were not properly labeled. A Tone Generator is connected to a Wall Jack, sends a repeating signal over the Cable. The Probe can then be used to detect which cable is connected to the Wall Jack by detecting the signal being sent by the Tone Generator. The Probe needs to be near or touch the cable with the tone generator attached to identify it positively.
A Cable Tester is used to ensure a cable is properly created as patch cable (Straight Through) or a Cross Over Cable. Cable Testers provide detailed information on the physical and electrical properties of a cable.
Punchdown Tools are used to connect an ethernet cable to the back of a Patch Panel, a punchdown block or the back of a network wall jack.
Multimeter can measure the Voltage or Amperage and Resistance of a Circuit. A Multimeter can be a hand-held device useful for basic fault finding and field service work or a bench instrument that can measure electricity with a High degree of accuracy.

- A Computer tech is configuring a NAS for a company to store their corporate data. The tech has installed x3 6TB Hard Drives operating at 7200 RPM in a RAID 5 Config. HOw much usable storage space is contained in the NAS?
6TB
18TB
12TB
3TB
12TB
EXPLANATION:
RAID 5 provides block-level stripping with distributed parity to provide redundancy using a minimum of 3 Disks. Since the NAS uses a RAID 5 config, it is a stripped array with parity. The 3 6TB HDDs are installed, but 33% of the storage capacity will store the parity information. This leaves only 12 TB of usable storage space in the NAS when using the RAID 5 Config.
A Technician needs to upgrade the RAM in a Database Server. The server’s memory must support maintaining the Highest Levels of Integrity. Which of the following type of RAM should the tech install?

- The large multi-function printer in your office is shared between 12 people. Unfortunately, it has stopped working, and the Techs have determined it must be replaced. A New Printer has been ordered, but it will be 2 weeks until it arrives. The only other printer available in your office is the manager’s printer, but it is connected via USB to their Workstation. ONe of the Techs would like to share the Manager’s printer with the other 12 Employees for the next 2 weeks as a temporary workaround. Unfortunately, there is no space wired network jacks available in the office to connect the printer to the Network directly, but there is a Wireless Access point nearby. Which of the following is the BEST way for the Tech to allow the 12 employees to access the manager’s printer?
Configure a New Printer on each user’s workstation and point it to the Manager’s IP Address.
Share the Printer Directly from the Manager’s Computer by Creating a Share and giving the other employees access to the Share.
Purchase a Portable Wireless Print Server and Connect the Printer to it using a USB
Provide a USB thumb drive to each employee so they can transfer their files to the manager’s computer for direct printing.
Purchase a Portable Wireless Print Server and Connect the Printer to it using a USB.
EXPLANATION:
The BEST solution would be to use a wireless print server to connect the printer to it using USB. This wireless print server can then receive the print jobs directly from all of the network users.
It is not recommended that the technician create a share on the manager’s computer or set the printer configuration to the manager’s IP address since all print jobs would fail anytime the manager shut down or restarted their computer.
Using a USB drive to transfer the files to the manager’s computer each time someone wanted to print is also not a good solution since this is difficult for the users and will be disrupting the manager’s work every time someone needed to print something.
- Which type of Technology imitates Hardware without relying on the CPU being able to run the Software code directly?
Virtual Machine
Emulator
Hypervisor
Simulator
Emulator
EXPLANATION:
Emulators emulate Hardware without relying on the CPU being able to run Code directly.
Virtual Machines use CPU Self-Virtualization, to whatever extent it exists, to provide a Virtual interface to the real hardware.
A Simulator is a limited scope that is usually used in training to mimic a real system’s functionality.
Emulators were created before Virtualization and operate much slower than a True Virtualization environment with a Hypervisor.
- Which of the following is True of a Dedicated Video Card in a Computer System?
Less Expensive than an integrated Video Card
Can be upgraded or replaced.
Share the use of the System’s Memory
Cannot be upgraded or replaced.
Can be upgraded or replaced.
EXPLANATION:
It is more expensive to have a Dedicated GPU or Video Card, but it does provide Higher Performance than an Integrated GPU. A Dedicated GPU also can be upgraded with a Newer Graphics Card in the future to increase performance.
An Integrated Video card is built as part of the main system Motherboard or CPU. An Integrated GPU is cheaper than a Dedicated GPU, but it has limited performance and shares the use of the Computer’s System RAM. An Integrated Video Card cannot be upgraded since it is part of the Processor or Motherboard.
If a System is being designed for Gaming, Video Editing, or 3D Rendering, it should use a separate Video Card with a Dedicated GPU.

- A Client has asked you to build a computer to use as part of their Home Theater (HTPC) System. The HTPC will be used primary to stream videos in their living room and must have a small form factor to fit into their entertainment center next to their surround sound system. Which of the following motherboards would be the BEST choice for an HTPC System?
ITX
ATX
Mini-ITX
Micro-ATX
Mini-ITX
EXPLANATION:
Mini-ITX is the most commonly used Form Factor for HTPC Systems because they require the smallest fans or passive cooling, which minimizes the noise productid by the system.
Micro-ATX Motherboards also require a larger (And Louder) Fan to keep the system cooled, so it is a poor choice for an HTPC.
An ATX or ITX Motherboard is a bad choice since they are larger and would not fit into a Traditional HTPC Case.

- An Inkjet Printer is printing images and text at an angle, and sometimes they don’t print at all. Which of the following would a technician perform to align a printer?
Replace the Print Head
Maintenance Cleaning
Calibration
Replace the Cartridge
Calibration
EXPLANATION:
The Tech should first calibrate the printer and perform a Print Test. Usually it aligns the print heads during calibration and prints out a test page with a code for the user to enter and print another test page to ensure it is properly aligned. A Printer that has alignment problems will not print documents accurately. Your printer can become misaligned if there is any paper stuck in the machine, print cartridges are clogged or dirty, improper installation of cartridges, and using low-quality cartridges. Additionally, a printer can become misaligned after the machine completes a large print job.
