  5. 11ac
A
  1. 11a
  2. 11ac

Explanation: 802.11a operates at 5 GHz only; so does 802.11ac.

Incorrect answers: 802.11b and g operate at 2.4 GHz. 802.11n operates at either 2.4 or 5 GHz. The IEEE 802.11 wireless standards are collectively known as 802.11x. However, there is no actual 802.11x standard; it was not used in order to avoid confusion. 802.11x is instead a variable that you may sometimes see that refers to two or more 802.11 technologies.

Q
  • Which of the following types of RAM has a Peak Transfer rate of 21,333 MB/s?

DDR4-1600
DDR4-2133
DDR4-2400
DDR4-2666

A

DDR4-2666

Explanation: DDR4-2666 has a peak transfer rate of 21,333 MB/s. It runs at an I/O bus clock speed of 1333 MHz and can send 2666 megatransfers per second (MT/s). It is also known as PC4-21333. The math: To figure out the data transfer rate of DDR4 from the name “DDR4-2666,” simply multiply the 2666 by 8 (bytes) and solve for megabytes: 21,333 MB/s. To figure out the data transfer rate of DDR4 by the consumer name “PC4-21333,” just look at the number within the name and add “MB/s” to the end. To figure out the data transfer rate when given only the I/O bus clock speed (for example, 1333 MHz), multiply the clock speed by 2 and then multiply that number by 8 and solve for megabytes: 1333 MHz × 2 × 8 = 21,333 MB/s. However, keep in mind that a RAM module such as DDR4-2666 is often inaccurately referred to as a 2666-MHz RAM module, but really that is the MT/s.

Incorrect answers: DDR4-1600 has a peak transfer rate of 12,800 MB/s; it is also known as PC4-12800. DDR4-2133 has a peak transfer rate of 17,066 MB/s; it is also known as PC4-17000. DDR4-2400 has a peak transfer rate of 19,200 MB/s; it is also known as PC4-19200.

Q
  • Which of the following is a possible symptom of a failing CPU?

CPU is beyond the recommended voltage range.
Computer won’t boot.
BIOS reports low temperatures within the case.
Spyware is installed into the browser.

A

CPU is beyond the recommended voltage range.

Explanation: If the CPU is running beyond the recommended voltage range for extended periods of time, it can be a sign of a failing CPU. The problem could also be caused by overclocking. Check in the UEFI/BIOS to see whether or not the CPU is overclocked.

Incorrect answers: If the computer won’t boot at all, another problem might have occurred, or the CPU might have already failed. Low case temperatures are a good thing (if they aren’t below freezing!), and spyware is unrelated to this issue.

Q
  • What is an LCD display’s contrast ratio defined as?

Power Consumption
Display Resolution and Brightness
The Brightest and Darkest Outputs
Power Savings

A

The Brightest and Darkest Outputs

Explanation: Contrast ratio is the brightness of the brightest color (measured as white) compared to the darkest color (measured as black). Static contrast ratio measurements are static; they are performed as tests using a checkerboard pattern. But there is also the dynamic contrast ratio, a technology in LCD displays that adjusts dynamically during darker scenes in an attempt to give better black levels. It usually has a higher ratio, but it should be noted that there is no real uniform standard for measuring contrast ratio.

Incorrect answers: Power consumption deals with the number of watts that the display uses. Display resolution is the number of pixels on the screen, measured horizontally by vertically. Displays often have a brightness setting as well as a contrast setting. The brightness setting is used to increase or decrease the amount of light put out by the display. Power savings is another concept altogether and can be adjusted by enabling the power savings feature of the operating system, ultimately using fewer watts and conserving energy while increasing the life span of the display.

Q
  • Which of the following devices limits network broadcasts, segments IP address ranges, and interconnects different physical media?

Switch
WAP
Firewall
Router

A

Router

Explanation: A router can limit network broadcasts through segmenting and programmed routing of data. This is part of a router’s job when connecting two or more networks. It is also used with different media. For example, you might have a LAN that uses twisted-pair cable, but the router connects to the Internet via a fiber-optic connection. That one router will have ports for both types of connections.

Incorrect answers: A switch connects multiple computers on the LAN; it does not limit IP-based network broadcasts. However, the switch does not segment by IP address; it communicates with computers and segments the network via MAC addresses. Also, the switch normally uses one type of media—twisted pair, connecting to RJ45 ports. However, it is possible that the switch might connect to another switch by way of a specialized fiber-optic connector. A wireless access point (WAP) connects the computers on the wireless LAN (WLAN). It often has only one connection, a single RJ45 port. A hardware-based firewall usually connects to the network via RJ45; regardless, it has only one or only a few connections. It doesn’t deal with routing or broadcasts; instead, it prevents intrusion to a network.

  • Which of the following operating CPU temperatures is typical?

60 Fahrenheit
60 Celsius
72 Fahrenheit
72 Celsius

A

60 Celsius

Explanation: A typical operating temperature for CPUs is 60° Celsius. Keep in mind that the operating range may be above or below that. Many computers hover around 30° to 35° Celsius.

Incorrect answers: On the other hand, 72° Celsius becomes much less typical, even if the user is overclocking the system. A temperature of 60° Fahrenheit is equal to 15.5° Celsius. A processor will not run that cold (but it would be pretty efficient if it did!). A temperature of 72° Fahrenheit falls within the range of room temperature and is what you should set the room temperature for computers to run at their best.

  • Which of the following is NOT a configuration that can be made in the UEFI/BIOS?
Boot Sequence
Temperature Thresholds
Overclocking
Install Drives
Intrusion Detection
A

Intrusion Detection

Explanation: You cannot install drivers to the UEFI/BIOS. Drivers are software that allows the operating system to communicate with hardware; they can be configured in the Device Manager in Windows.

Incorrect answers: The rest of the answers can be configured in the BIOS. The boot sequence (also known as boot priority or boot order) allows you to select which device will be booted off first. (The hard drive is the most secure.) Temperature thresholds allow you to set alerts and possibly shut down the system if the CPU runs too hot. Overclocking occurs when the CPU’s voltage is raised and the speed is increased. Overclocking is not recommended, but if you do configure it, you should set temperature thresholds. Intrusion detection can be enabled and will log if a person opened the computer case.

Q

To perform a network installation of Windows, which of the following must be supported by the computer’s network interface card?

PXE
PCIe
PCL
PnP

A

PXE

Explanation: Network installations require that the network card be configured for Preboot eXecution Environment (PXE). This allows the network card to boot off the network, locate a network installation server, and request that the installation begin. This configuration might be done in the UEFI/BIOS of the computer (if the network adapter is integrated to the motherboard), within a special program in Windows, or in one that boots from disc or other removable media (if the network adapter is an adapter card).

Incorrect answers: Peripheral Component Interconnect Express (PCIe) is an expansion bus that accepts video cards, network adapter cards, sound cards, and so on. PCL stands for Printer Command Language, developed by HP so that a computer can properly communicate with impact or thermal printers. PnP stands for plug and play, a Windows technology that allows devices to be located and installed automatically.

1000 bits per second
1,000,000,000 bits per second
1 gigabit per second

A

1,000,000,000 bits per second
1 gigabit per second

Explanation: 1000 Mbps is 1000 megabits per second, otherwise notated as 1,000,000,000 bits per second, or 1 gigabit per second.

Incorrect answers: Data transfer is measured in bits per second (bps), not bits per minute. Consequently, 1000 bits per second would be very slow. At their peak, dial-up modems would transfer 56,000 bits per second, and that is considered the slowest Internet access you could find in the United States.

  • Which of the following is the typical speed of an SATA hard disk drive?

1000 Mbps
3.1 GHz
32 GB
7200 RPM

A

7200 RPM

Explanation: A typical speed of a magnetic hard disk drive is 7200 RPM—rotational speed, that is. Other common rotational speeds include 5400 RPM, 10,000 RPM, and 15,000 RPM. Note: Solid-state hard drives do not have a magnetic disk and therefore are not given an RPM rating or a latency rating.

Incorrect answers: A common network data transfer rate is 1000 Mbps. SATA hard drives commonly have a DTR of 6 Gb/s (600 MB/s). Note that 3.1 GHz is a
common CPU frequency, and 32 GB might be the amount of RAM you install in a computer or the size of a USB flash drive.

  • Your organization relies heavily on its server farm for resources and is less reliant on the client computers. Which type of client computer is most likely used by the organizations?

Virtualization Workstation
Client/Server
Thin Client
Thick Client

A

Thin Client

Explanation: In this scenario, the organization probably has thin client computers for its users. These computers have operating systems that are embedded in flash memory, and the rest of the information they require comes from a server. Thin clients normally have no hard drive; this is why they are referred to as diskless workstations.

Incorrect answers: Virtualization workstations definitely need a hard drive and require lots of other resources; they are not as dependent on servers. Client/server is a type of networking organizational technique. However, thin clients often log in to a server. Thick clients are, for the most, part PCs, the typical desktop computer.

Cleans the drum

A

Conditions the drum to be written to.
Transfers toner from the drum to the paper

Explanation: Know the main steps of the laser printer imaging process: processing, charging, exposing, developing, transferring, fusing, and cleaning. In the charging step, the drum is conditioned/charged by the primary corona wire (negatively charging it) and is prepared for writing. In the transferring step, the paper is positively charged by the transfer corona wire, preparing it to accept the toner from the drum.

Incorrect answers: In the fusing step, the toner is fused to the paper with heat and pressure. In the cleaning step (the last step), the receptacle, rollers, and other items are cleaned and readied for the next print job.

Q
  • A Customer reports that when this computer is turned on, the screen is blank except for some text and a flashing cursor. He also tells you that there are numbers counting upward when the computer beeps and then freezes. Which of the following is the most likely cause of this problem?

The computer has faulty memory.
There is a corrupt MBR
The OS is corrupted
The computer is attempting to boot off the Network.

A

The computer has faulty memory.

Explanation: Chances are that the computer has faulty memory or a memory module that needs to be reseated properly. The flashing cursor on the screen tells you that the system is not posting properly. The numbers counting up are the system checking the RAM. If the system beeps and freezes during this count-up, the RAM has an issue. It could also be incompatible with the motherboard.

Incorrect answers: A corrupt MBR would either give a message stating “missing OS” or “the MBR is corrupt.” However, most systems today are GPT-based, not MBR-based. If the OS was corrupted, you would get a message to that effect. If the computer attempts to boot off the network, you will see gray text and a spinning pipe sign as it attempts to find a DHCP server.

  • A customer reports that print jobs sent to a local printer are printing as blank pieces of paper. Which of the following can help you determine the cause?

Reload the printer drivers.
Stop and restart the print spooler
Replace the printer cable
Print an internal test page.

A

Print an internal test page.

Explanation: First, try printing an internal test page, meaning from the printer’s onscreen display. If that doesn’t work, you need to start troubleshooting the printer. Perhaps the toner cartridge is empty, or maybe a corona wire is malfunctioning.

Incorrect answers: If the test page prints fine, you can check the printer drivers and other settings at the computer that uses the printer. Restarting the spooler should not help in this situation. If the spooler stalled, no paper should come out of the printer. Likewise, the printer cable should not have to be replaced.

Q
  • Which of the following measurements is the typical latency of an SATA hard drive?

300 MB/s
7200 RPM
64 MB
4.2 ms

A

4.2 ms

Explanation: The typical latency of an SATA magnetic-based hard disk drive is 4.2 ms (milliseconds). When you are dealing with magnetic drives, latency is the delay in time before a particular sector on the platter can be read. It is directly linked to rotational speed. A hard drive with a rotational speed of 7200 RPM has an average latency of 4.2 ms.

Incorrect answers: Note that 300 MB/s is the data transfer rate of an SATA revision 2.0 hard drive; it is also expressed as 3.0 Gb/s. Also, 7200 RPM is the rotational speed of the drive, and 64 MB is a common amount of cache memory on a hard drive; it is usually DRAM.

Q
  • A Customer wants users to be able to store additional files in a cloud-based manner when necessary and remove them when they are not needed anymore. What is this known as?
Resource Pooling
Virtual Application Streaming
Shared Resources
On-Demand
Synchronization Application
A

Synchronization Application

Explanation: On-demand means that a customer can get access to cloud-based services 24 hours a day, 7 days a week and that the customer can get additional space if needed on a temporary basis. This links with scalability to a certain extent.

Incorrect answers: Resource pooling occurs when resources (RAM and CPU), servers, and infrastructure are shared by multiple customers. However, shared resources, in general, are resources that are shared for use by remote users. Virtual application streaming refers to applications (such as email clients) that are served from a cloud provider and run within a virtual machine or instance of some sort. Synchronization applications are programs that will aid in the synchronization of data between a client and a server on the cloud. For example, a single synchronization program might take care of the sync of data for several programs, such as email, calendar, and contacts.

Q
  • Which of the following is used to measure TDP?

Volts
Watts
Ohms
Amps

A

Watts

Explanation: The thermal design power (TDP) of a CPU is measured in watts. For example, a typical Core i7 CPU might be rated at 140 watts or less. The less the wattage rating, the less the computer’s cooling system needs to dissipate heat generated by the CPU.

Incorrect answers: Volts is potential energy; it is a measurement commonly associated with internal PC components running at 5- or 12-volt DC and with typical household and business AC outlets running at 120 volts or 240 volts. Ohms is the measurement used for impedance, or the resistance to electricity. Amps is the measurement for electric current. A typical computer might use 4 amps of current if it has a 500-watt power supply.
