    When installing a network adapter into a client computer, a technician notices that the contacts on the adapter need to be cleaned. Which solution should the technician use to clean the contacts?

    • A.

      Isopropyl alcohol

    • B.

      Mild detergent

    • C.

      Slightly abrasive cleanser

    • D.

      Glass cleaner

    Correct Answer
    A. Isopropyl alcohol
    Explanation
    Isopropyl alcohol is the correct solution to clean the contacts on a network adapter. Isopropyl alcohol is commonly used as a cleaning agent for electronic components because it evaporates quickly, leaves no residue, and is safe to use on sensitive electronics. It effectively removes dirt, dust, and oils from the contacts without causing any damage. Mild detergent, slightly abrasive cleanser, and glass cleaner may be too harsh or leave residue on the contacts, which could interfere with the proper functioning of the network adapter.

    Class ... fire extinguishers are good for gasoline and kerosene fires.

    Correct Answer
    B
    Explanation
    Class B fire extinguishers are designed to handle flammable liquid fires such as gasoline and kerosene. These types of fires involve combustible liquids that can easily spread and ignite. Class B extinguishers are effective in extinguishing these fires by smothering the flames and cutting off the oxygen supply. They are typically filled with a foam or dry chemical agent that can quickly suppress the fire. Therefore, it is appropriate to use Class B fire extinguishers for gasoline and kerosene fires.

    A network administrator has finished migrating from a peer-to-peer network to a new client-server network configuration. What are two advantages of the new configuration? (Choose two.)

    • A.

      The total cost of the new solution is considerably lower.

    • B.

      Data resources and access are centrally controlled.

    • C.

      Personnel costs are lower because a dedicated network administrator is no longer necessary.

    • D.

      Data is more secure in the event of hardware failures.

    • E.

      Individual users are in control of their own computers and network resources.

    Correct Answer(s)
    B. Data resources and access are centrally controlled.
    D. Data is more secure in the event of hardware failures.
    Explanation
    The new client-server network configuration allows for central control of data resources and access, ensuring that all data is stored and managed in a centralized location. This improves efficiency and streamlines the management of data within the network. Additionally, the new configuration provides increased security in the event of hardware failures, as data is stored on dedicated servers rather than individual computers. This reduces the risk of data loss and ensures that data can be easily recovered in case of hardware failures.

    A ......... is used to draw heat away from the cpu.

    Correct Answer
    fan
    Fan
    Explanation
    A fan is used to draw heat away from the CPU. Fans are commonly used in computer systems to cool down the CPU and prevent it from overheating. They work by circulating air around the CPU, dissipating the heat generated by its operation. The movement of the fan blades creates airflow, which helps to remove the hot air and bring in cooler air, thus maintaining a safe operating temperature for the CPU.
