    Explanation
    Random access memory (RAM) is considered to be a computer's main storage because it is responsible for temporarily storing data that the computer is actively using. Unlike other types of memory such as ROM, BIOS, or CMOS, RAM can be both read from and written to, making it ideal for storing and accessing data quickly. It allows the computer to quickly retrieve and manipulate data, which is essential for running programs and performing tasks efficiently.

    (202) Which interrupt request (IRQ) line number is normally used for the floppy disk controller?

    • 2.

    • 4.

    • 6.

    • 8.

    Correct Answer
    A. 6.
    Explanation
    IRQ line number 6 is normally used for the floppy disk controller. The floppy disk controller is a device that manages the reading and writing of data to a floppy disk. IRQ lines are used to signal the CPU when a device needs attention or when a specific event occurs. IRQ line 6 is typically assigned to the floppy disk controller, allowing it to communicate with the CPU and perform its functions effectively.

    (204) The hard drives in a redundant array of independent disks (RAID) array are presented to the server as 

    • One single hard drive.

    • A collection of hard drives.

    • A single RAID array.

    • A single RAID array.

    Correct Answer
    A. One single hard drive.
    Explanation
    The correct answer is one single hard drive. In a redundant array of independent disks (RAID) array, multiple hard drives are combined to appear as a single hard drive to the server. This is done through a technique called disk striping, where data is divided and distributed across the drives in the array. The server sees and interacts with the RAID array as if it were a single drive, providing increased performance, fault tolerance, and storage capacity.

    (204) Which technology is often used in redundant array of independent disks (RAID) array that can be daisy chained? 

    • Small computer system interface (SCSI).

    • Serial attached (SAS) SCSI.

    • Serial advanced technology attachment (SATA).

    • Peripheral component interconnect express (PCIe).

    Correct Answer
    A. Small computer system interface (SCSI).
    Explanation
    SCSI (Small Computer System Interface) is often used in redundant array of independent disks (RAID) arrays that can be daisy chained. SCSI allows multiple devices to be connected in a chain, with each device having its own unique identifier. This allows for easy expansion and scalability in RAID arrays, as additional disks can be added to the chain without disrupting the existing setup. SCSI also offers high data transfer rates and supports multiple devices on a single bus, making it a suitable technology for RAID arrays.

    (210) Which type of backup would you use at the end of the week to save all data that you select on your systems? 

    • Incremental.

    • Differential.

    • Daily.

    • Normal.

    Correct Answer
    A. Normal.
    Explanation
    At the end of the week, a normal backup would be used to save all the selected data on the systems. A normal backup involves backing up all the selected data regardless of whether it has been modified or not. This ensures that a complete copy of all the data is saved and can be restored if needed. Incremental backups only save the data that has changed since the last backup, differential backups save all the data that has changed since the last normal backup, and daily backups save all the data that has changed within a day.

    (211) What is a set of rules that can be set to affect active directory leaf objects to control what can be done by a user? 

    • Access control lists.

    • Access policy objects.

    • Group policy objects.

    • Group rules sets.

    Correct Answer
    A. Group policy objects.
    Explanation
    Group policy objects are a set of rules that can be set to affect active directory leaf objects to control what can be done by a user. These objects allow administrators to manage and enforce various settings, such as security settings, software installation, and user preferences, across a network. By applying group policy objects, administrators can ensure consistent and centralized control over the configuration and behavior of user accounts and computers in an active directory environment.

    (212) Which of the following is not one of the elements that most graphical user interfaces are composed of? 

    • Windows.

    • Icons.

    • Menus.

    • Programs.

    Correct Answer
    A. Programs.
    Explanation
    Most graphical user interfaces are composed of windows, icons, and menus. Programs, on the other hand, are not an element of the graphical user interface itself, but rather the software applications that run within the interface. While programs may be accessed and interacted with through the interface, they are not considered a fundamental element of the interface itself.

    (214) Which software program manages an IP address allocation for a network?

    • Dynamic host configuration protocol (DHCP).

    • Domain name service (DNS).

    • Active directory (AD).

    • DHCP server.

    Correct Answer
    A. Dynamic host configuration protocol (DHCP).
    Explanation
    The correct answer is Dynamic host configuration protocol (DHCP). DHCP is a software program that manages the allocation of IP addresses for a network. It automatically assigns IP addresses to devices on a network, eliminating the need for manual configuration. DHCP also handles other network configuration parameters such as subnet masks, default gateways, and DNS server addresses. It allows for efficient management and allocation of IP addresses, making it an essential component of network administration.
