    Which of the following cable types is required for a BNC connector?

    • Fiber Optic

    • Coaxial

    • CAT5

    • CAT3

    Correct Answer
    A. Coaxial
    Explanation
    A BNC connector is commonly used for coaxial cables, which transmit signals over long distances with minimal loss. Coaxial cables consist of a central conductor, an insulating layer, a metallic shield, and an outer insulating layer. This design allows for efficient transmission of high-frequency signals, making them suitable for applications such as television broadcasting and computer networking. Fiber optic cables, on the other hand, use light signals for data transmission and are not compatible with BNC connectors. CAT5 and CAT3 cables are used for Ethernet networking and telephone connections respectively, and are not typically used with BNC connectors.

    Which of the following must be performed when installing a touch screen?

    • Disable the keyboard

    • Calibration

    • Boot the computer in safe mode

    • Disable the mouse

    Correct Answer
    A. Calibration
    Explanation
    Calibration is necessary when installing a touch screen because it ensures that the touch screen accurately responds to touch inputs. This process involves adjusting the sensitivity and accuracy of the touch screen so that it can correctly interpret and respond to user interactions. By calibrating the touch screen, it ensures that the touch inputs are registered correctly and that the user's actions are accurately translated on the screen.

    Which of the following chipsets is responsible for controlling the data flow between the RAM and the processor?

    • Northbridge

    • DMA controller

    • CMOS

    • Southbridge

    Correct Answer
    A. Northbridge
    Explanation
    The Northbridge chipset is responsible for controlling the data flow between the RAM and the processor. It acts as a bridge connecting the CPU to the main memory and high-speed peripherals. It handles tasks such as coordinating data transfers, managing memory access, and controlling the system bus. The Northbridge chipset plays a crucial role in ensuring efficient communication and data transfer between the processor and RAM, making it the correct answer.

    The most effective use of clusters on a hard drive is in which of the following file systems?

    • FAT12

    • FAT16

    • FAT32

    • NTFS

    Correct Answer
    A. NTFS
    Explanation
    The most effective use of clusters on a hard drive is in the NTFS file system. NTFS (New Technology File System) is a modern file system that provides better performance, reliability, and security compared to the older FAT file systems. NTFS uses a more efficient cluster allocation method, allowing for larger cluster sizes and reducing wasted space on the hard drive. This results in improved disk performance and better storage utilization.

    Which of the following RAM types is used to resolve certain memory errors?

    • Non-ECC

    • Non-parity

    • ECC

    • Parity

    Correct Answer
    A. ECC
    Explanation
    ECC (Error Correcting Code) RAM is used to resolve certain memory errors. It is designed to detect and correct single-bit memory errors, ensuring data integrity and preventing system crashes or data corruption. ECC RAM is commonly used in servers, workstations, and other critical systems where data accuracy is crucial. Non-ECC and non-parity RAM do not have error correction capabilities, while parity RAM can detect but not correct errors. Therefore, ECC RAM is the correct choice for resolving memory errors.

    A first level help desk support technician receives a call from a customer and works with the customer to resolve the call for several minutes unsuccessfully. Which of the following should the technician do NEXT?

    • Continue working with the customer until the problem is resolved.

    • Explain to the customer that they receive a call back when someone more qualified is available.

    • Explain to the customer that the problem cannot be resolved and end the call.

    • Escalate the call to another technician.

    Correct Answer
    A. Escalate the call to another technician.
    Explanation
    The technician should escalate the call to another technician because they have been unable to resolve the issue after working with the customer for several minutes. By escalating the call, the technician can ensure that the problem is addressed by someone with more expertise or experience, increasing the chances of a successful resolution for the customer.

    Which of the following cable types supports a transmission speed no greater than 100 Mbps per the IEEE specification?

    • CAT3

    • CAT4

    • CAT5

    • CAT6

    Correct Answer
    A. CAT5
    Explanation
    CAT5 cable supports a transmission speed no greater than 100 Mbps per the IEEE specification. CAT5 cables are commonly used for Ethernet networks and can support speeds up to 100 Mbps. However, they are not capable of supporting higher speeds such as those provided by CAT6 cables.

    Which of the following IP addresses is in a class A range?

    • 15.26.2.1

    • 156.10.2.5

    • 192.168.0.1

    • 202.45.16.8

    Correct Answer
    A. 15.26.2.1
    Explanation
    The IP address 15.26.2.1 is in a class A range because it falls within the range of 1.0.0.0 to 126.0.0.0. Class A IP addresses have the first octet as the network portion and the remaining three octets as the host portion. In this case, the first octet is 15, which is within the range for class A addresses.

    Which of the following memory modules uses a 240-pin connector?

    • DDR

    • SIMM

    • DDR2

    • RAMBUS

    Correct Answer
    A. DDR2
    Explanation
    DDR2 memory modules use a 240-pin connector. DDR (Double Data Rate) memory modules use a 184-pin connector, SIMM (Single In-Line Memory Module) uses a 72-pin or 30-pin connector, and RAMBUS memory modules use a 184-pin or 232-pin connector. Therefore, the correct answer is DDR2.
