Questions and Answers
  • 1. 

    You need to change some settings on your Apache server. Which is the best tool to use for logging in remotely?

    • A.

      Rsh

    • B.

      Ssh

    • C.

      Rlogin

    • D.

      Telnet

    • E.

      Login

    Correct Answer
    B. Ssh
    Explanation
    SSH (Secure Shell) is the best tool to use for logging in remotely to an Apache server. It provides a secure and encrypted connection, ensuring that the data transmitted between the client and the server is protected from unauthorized access. On the other hand, tools like rsh, rlogin, telnet, and login do not provide the same level of security and encryption as SSH, making them less suitable for remote logins.

    Which of the following runlevel will reboot the system?

    • A.

      0

    • E.

      1

    Correct Answer
    D. 6
    Explanation
    Runlevel 6 is the correct answer because it is the runlevel that initiates a system reboot. In Linux, runlevels are specific operating modes that determine which services and processes are running. Runlevel 6 is typically used for system reboot, as it stops all processes and services, unmounts filesystems, and then restarts the system. Runlevels 0, 1, 2, and 4 have different purposes, such as shutdown, single-user mode, multi-user mode, or custom configurations, but they do not initiate a system reboot like runlevel 6 does.

    • B.

      Chmod 100 fifteen

    • C.

      Chmod 700 fifteen

    • D.

      Chmod fifteen 100

    • E.

      Chmod 770 fifteen

    Correct Answer
    C. Chmod 700 fifteen
    Explanation
    The correct answer is "chmod 700 fifteen". The command "chmod" is used to change the permissions of a file. The number "700" represents the permissions for the file, where the first digit (7) represents the permissions for the owner (root), the second digit (0) represents the permissions for the group, and the third digit (0) represents the permissions for other users. In this case, "7" gives the owner (root) read, write, and execute permissions, while "0" denies all permissions to the group and other users. Therefore, using "chmod 700 fifteen" will change the permissions of the file "fifteen" as desired.

    The cat command in Unix and Linux systems stands for "concatenate." Its primary function is to read, concatenate, and display the contents of files to the standard output. This means cat can be used to view the contents of a file, as well as to merge several files into one. For example, using cat file1 file2 > mergedfile combines the contents of file1 and file2 into a new file called mergedfile. This versatile command is essential for handling text data within the command line environment.

    E. >>
    Explanation
    ">>" is used for appending output to a file. Similarly, the cat command can be used to append text or data from one file to another using a command like cat file1 >> file2, which appends the contents of file1 to file2.

    If you are installing a software package from source code, the file will typically have which extension?

    • A.

      .src

    • B.

      .exe

    • C.

      .tgz

    • D.

      .bff

    • E.

      .bin

    Correct Answer
    A. .src
    Explanation
    When installing a software package from source code, the file will typically have the .src extension. This extension indicates that the file contains the source code of the software, which is the original code written by the developers. By compiling this source code, the software can be built and installed on the system. Other extensions like .exe, .tgz, .bff, and .bin are commonly used for executable or compressed files, but when installing from source code, the .src extension is the most appropriate.

    You have written a shell script that must be run as root in order to work properly. What is the most secure way to give a normal user the ability to run this program?

    • A.

      Set permissions to 777 on the script

    • B.

      Make the user a member of the root group

    • E.

      Change the group of the user to same of the owner

    Correct Answer
    D. Set the SUID bit on the script
    Explanation
    The most secure way to give a normal user the ability to run a shell script that must be run as root is to set the SUID (Set User ID) bit on the script. This allows the script to be executed with the privileges of the file's owner (in this case, root), even when it is run by a normal user.
