    You want to perform multiple backups of only those files that are modified since the last normal backup. You also want to ensure that the backed up files use minimum amount of media. In this case, you will take a:

    • Normal backup.

    • Differential backup.

    • Incremental backup

    • Copy backup

    Correct Answer
    A. Incremental backup
    Explanation
    An incremental backup is the best choice in this scenario because it only backs up the files that have been modified since the last normal backup. This means that it will use the minimum amount of media since it only includes the changes made since the last backup. Differential backup would include all the changes made since the last normal backup, not just the modified files. A copy backup would create a duplicate copy of all the files, regardless of whether they have been modified or not.

     What does an assigned IP address 169.254.0.12 indicate? 

    • The computer is configured with a static IP address.

    • The computer is using a dial-up modem.

    • The computer is being used as an Internet shared connection host

    • The computer is configured for DHCP and cannot connect to the DHCP server

    • The computer has been configurd to work with a Linux system.

    Correct Answer
    A. The computer is configured for DHCP and cannot connect to the DHCP server
    Explanation
    The assigned IP address 169.254.0.12 indicates that the computer is configured for DHCP and cannot connect to the DHCP server. This address falls within the Automatic Private IP Addressing (APIPA) range, which is used when a computer is unable to obtain an IP address from a DHCP server. The APIPA address is assigned automatically by the computer itself, allowing it to communicate with other devices on the local network. However, since it cannot connect to the DHCP server, it is unable to obtain a valid IP address.

  • 22. 

    What does FDISK do? 

    • Performs low-level formatting of the hard drive.

    • Fixes bad sectors on the hard drive.

    • Recovers lost clusters on the hard drive.

    • Creates partitions on the hard drive.

    Correct Answer
    A. Creates partitions on the hard drive.
    Explanation
    FDISK is a utility that is used to create partitions on a hard drive. Partitions divide the hard drive into separate sections, allowing different file systems or operating systems to be installed on each partition. This enables better organization and management of data on the hard drive. FDISK does not perform low-level formatting, fix bad sectors, or recover lost clusters on the hard drive.

    Rate this question:

  • 23. 

    Which of the following RAID levels uses a fault-tolerance technique known as "disk mirroring"?

    • Raid 0

    • Raid 1

    • Raid 5

    • Raid 10

    Correct Answer
    A. Raid 1
    Explanation
    RAID 1 is the correct answer because it uses disk mirroring as a fault-tolerance technique. In RAID 1, data is written simultaneously to two or more drives, creating an exact copy or mirror of the data. This ensures that if one drive fails, the data can still be accessed from the remaining drive(s). RAID 0 does not provide fault tolerance, RAID 5 uses parity for fault tolerance, and RAID 10 combines disk striping and mirroring.

    Rate this question:

  • 24. 

    What does the term "Map Network Drive" mean?

    • Map the host HDD into memory locations.

    • Map a shortcut to a network location.

    • Map the path to the local area network gateway.

    • Send instructions to a user to map the remote local area network.

    • A schematic drawing of all mapped adapter locations on the network system.

    Correct Answer
    A. Map a shortcut to a network location.
    Explanation
    The term "Map Network Drive" refers to the process of creating a shortcut to a network location on a computer. This allows the user to easily access and navigate to the network location as if it were a local drive or folder on their computer. It simplifies the process of accessing files and resources stored on a network, making it more convenient for users to work with networked data.

    Rate this question:

  • 25. 

    What is the minimum number of disks required for RAID 5?

    • 1

    • 2

    • 3

    • 4

    • 5

    • 6

    Correct Answer
    A. 3
    Explanation
    RAID 5 requires a minimum of 3 disks. In RAID 5, data is striped across multiple disks with parity information distributed across all the disks. This provides fault tolerance as the system can continue to function even if one disk fails. The minimum number of disks required is 3 because at least two disks are needed for data storage and one disk is needed for parity information.

    Rate this question:

  • 26. 

    What utility can you use to verify if a remote computer is accepting connections on the PORT you are connected to?

    • Ftp

    • Telnet

    • Snmp

    • Ping

    Correct Answer
    A. Telnet
    Explanation
    Telnet is the correct answer because it is a utility that allows you to establish a connection with a remote computer and verify if it is accepting connections on a specific port. By using Telnet, you can attempt to connect to the remote computer on the port you are connected to and check if the connection is successful. If the connection is established, it means that the remote computer is accepting connections on that port. If the connection fails, it indicates that the remote computer is not accepting connections on that port.
