26. A user has connected a USB 3.0 device to a computer using a 3 ft (1m) USB 3.0 cable. However, instead of an expected data transfer rate of up to 5 Gb/s, the user notes a data transfer rate of no more than 450 Mb/s. What is the most probable reason for this lower than expected data transfer rate?

    • The device was connected to a USB 2.0 port on the computer.
    • The cable used exceeds the maximum length that allows USB 3.0 to transfer data at 5Gb/s.
    • The device was connected to a USB 1.1 port on the computer.
    • The USB 3.0 cable is faulty.
      

      Answers Explanation & Hints: USB 2.0 allows transmission speeds up to 480 Mb/s and USB 1.1 allows transmission rates of up to 12 Mb/s in full-speed mode. A transmission speed of 450 Mb/s would indicate that a USB 2.0 port was used on the computer because USB devices can only transfer data up to the maximum speed allowed by the specific port. The generally accepted maximum length of a USB 3.0 cable is 9.8 ft (3m) which is three times the length of the cable used in this example, so the cable length is acceptable for full USB 3.0 capability. If a USB cable is faulty then no data transfer at all is likely to occur.

    • Establish a plan of action to resolve the problem.
    • Establish a theory of probable cause.
    • Document findings, actions, and outcomes.
      

      Answers Explanation & Hints: By suspecting that an operating system service pack has failed to install successfully, the technician has established a theory of probable cause of the problem. The next step would be to test the theory to determine the cause of the problem, followed by establishing a plan of action to resolve the problem. Documentation is the final step and would occur after the solution has been verified and the system restored to full functionality.

35. A computer locks up frequently, and no error message can be seen on screen. The problem occurs every time the user attempts to restart the computer. What is the most likely reason for this problem?

    • The index service is not running.
    • The power supply has failed.
    • A startup file has become corrupted.
    • The CPU is overheating.
      

      Answers Explanation & Hints: If the power supply has failed the PC would turn off or could display a stop error message if the failure is partial. The index service not running does not cause a PC to lockup. No startup file is likely to be corrupted as the issue appears during normal operation. An overheading CPU would cause the computer to lockup.

36. A technician suspects that a power supply is faulty. How can it be checked?

    • by checking the temperature of the power supply
    • by using a multimeter
    • by taking apart the power supply
    • by powering up the PC after disconnecting each connector in turn
      

      Answers Explanation & Hints: The temperature of the power supply does not indicate if it is operational. A PC technician should never open a power supply as dangerous voltages might still be present even when disconnected. Disconnecting the connectors in turn and powering the PC is not a recommended practice. In the absence of a power supply tester, a multimeter can allow to check if voltages are present.

82. What is an advantage of using a printer that is connected to a hardware print server compared with a computer-shared printer?

    • A computer that shares a printer always allows for faster printing of documents.
    • A hardware print server is always available to all users.
    • A computer that shares a printer always prioritizes the printing tasks.
    • A hardware print server will have more memory to store the print job than a computer will have that shares a printer.
      

      Answers Explanation & Hints: A PC sharing a printer is usually running multiple tasks simultaneously besides printing and is therefore slower to process and send documents to the printer. A disadvantage of hardware print servers is that they frequently contain less storage space for the print queue compared with a dedicated print server or a computer-shared printer.

83. A technician wants to allow many computers to print to the same printer, but does not want to affect the performance of the computers. What will the technician do to achieve this?

    • Use a software print server.

    • network cable
    • pick up roller
    • drum
    • fuser
      

      Answers Explanation & Hints: The drum is a metal cylinder that holds an electrostatic charge to pick up the toner powder. If the drum is defective, then the charge on the cylinder will not hold the correct latent image to attract the toner.

89. A technician is called to work on a laser printer that prints vertical lines on every printed page. Which laser printer part should be checked first?

    • pickup rollers
    • RAM
    • toner cartridge
    • wiper blade
      

      Answers Explanation & Hints: A vertical line could be a sign of a faulty drum or a problem with the toner cartridge. The toner cartridge is the easiest one to test if it is faulty and can be reused later if it turns out to not be the problem.

90. A technician is called to troubleshoot a problem where a user claims that none of the print jobs from this morning have printed. The technician sees that there is only one printer installed in the device list and it is a network printer shared with other users. What should the technician check?

    • the print queue
    • the IP address of the printer
    • the fuser assembly
    • the user rights to the printer
      

      Answers Explanation & Hints: A networked printer might have a backed up print queue caused by the printer being offline, out of paper, or a paper jam. There might also be a document stuck in the print queue causing all of the others after it to not print. Check the printer for any issues first then check the print queue and see if sending a different document to the top of the queue or canceling the document at the top of the queue frees up the printer.

91. A user reports that a “Document failed to print” message appears every time the network printer is restarted. What could be a cause of the problem?

    • The fuser is faulty.
    • The IP address on the printer is statically assigned.
    • The user rights to the printer have been configured incorrectly.
    • The IP address assigned to the printer is a duplicate IP address.
      

      Answers Explanation & Hints: Networked printers are commonly assigned a static IP address. A DHCP reservation can be made and the MAC address of the printer can be entered at the DHCP server so that the printer receives the same IP address each time, or a technician can just manually enter an IP address into the printer. Each device must have a unique IP address, and a duplicate one would cause a network printer to not function.

92. What are two functions of hypervisors? (Choose two.)

    • to partition the hard drive to run virtual machines
    • to protect the host from malware infection from the virtual machines
    • to manage virtual machines
    • to allocate physical system resources to virtual machines
    • to share the antivirus software across the virtual machines
      

      Answers Explanation & Hints: The hypervisor does not protect the hosting OS from malware. Neither does it allow sharing software across virtual machines. The hard drive of the supporting computer does not need to be partitioned to run virtual machines. The hypervisor creates and manages virtual machines on a host computer and allocates physical system resources to them.

93. A computer technician is asked to configure a workstation with two virtual machines. What would be the purpose of the configuration?

    • to have redundancy in case of hard drive failure
    • to increase the performance of the computer

    • to allow multiple applications, that require more RAM than is installed, to be active simultaneously
      

      Answers Explanation & Hints: In the process of virtualization, virtual machines are created. Different operating systems can be installed on each virtual machine without interfering with one another.

94. A computer technician creates a virtual environment. Which security measure should the technician take for the virtual machine running Windows 10, if any?

    • Each virtual machine should have antivirus software installed.
    • Because each virtual machine contains an operating system that is different from what is on the host computer, no security software is needed.
    • A hardware firewall should be placed between each virtual machine and the internet or it will be necessary to ensure that the Windows firewall is enabled on each virtual machine.
    • The virtual machine must use the same secure passwords as the host computer uses.
      

      Answers Explanation & Hints: Virtual machines are susceptible to the same security threats that a host computer is. All security measures that are recommended for a computer in a home or business environment should also be taken within the virtual environment.

101. A company owns servers for a particular corporate application. The servers are housed in an external data center. The company has an agreement with a cloud provider to spin up additional servers for the same application during peak usage. Which cloud model is the company using?

     • community
     • hybrid
     • private
     • public
       

       Answers Explanation & Hints: A private cloud is a cloud-based service where the company manages the devices or applications within the cloud. They are just located away from the business at a provider site. If a company is using a public cloud, a provider manages the devices or the applications or both for the company. A hybrid cloud is a combination of two types of clouds, and a common practice is a private and public cloud combination.

102. What is meant by a cloud service being metered?

     • The company is charged a monthly or annual fee for a specific service.
     • The company is charged based on the amount of service used.
     • The company is allowed unlimited access to a service during specific periods of time.
     • A special device is attached to the demarcation point where the service provider network ends and the company network starts.
       

       Answers Explanation & Hints: An unmetered cloud service is one where the service is free or it is charged on a monthly or annual basis. A metered cloud service has the charge based on how much the service is used. A company can also have an unmetered service up to a particular point and then the company is assessed additional charges based on how much additional services the company used.

103. A company has a few employees that are designers. The designers do not have the CAD application loaded on their local computer. Instead, the designers use a CAD application hosted by the application developer. Which type of virtualization is the company using?

     • DaaS

     • PaaS
     • SaaS
       

       Answers Explanation & Hints: Software as a Service (SaaS) is a cloud computing type that provides access to one or more applications through a server. This server is not owned or managed by the company using the application.

104. A Windows 10 computer has several printers configured in the Control Panel Devices and Printers window. Which printer will the computer choose to be the first option for printing?

     • the printer that is set as the default printer
     • the software-based printer that is used to create PDF files
     • the software-based printer that is used to create XPS files
     • a manual selection, which is always needed
       

       Answers Explanation & Hints: The Default Printer option is set globally and will be the first printer to print a job unless another printer is selected in a Per-Document manner. Software-based printers are just instances of different kinds of printers, but to be chosen to do the job, they will need to be selected as a default or Per-Document printer. Selecting a printer every time a printing job sends is not needed.

105. What problems can be resolved by implementing QoS and traffic engineering protocols in an enterprise VoIP network?

     • excessive latency and jitter
