Software Management
Question 1 of 25
Configuring yum to point to a custom repository can be done in either /etc/yum.conf or in which of the following?

*   Any file name with a .repo extension in /etc/yum.repos.d/ directory.
    Same directory as yum.conf but with a .repos extension
    Any file under /etc/yum/ as long as it has a .repo extension
    Any where in the file /etc/sysconfig/yum
    Any file under /etc/sysconfig/ with a .repo extension


The command ???yum list all??? will list all available packages and available groups of packages in all enabled repositories.

    TRUE
  * FALSE


Which command would discover the names of packages that are not yet installed on your system but available in enabled repositories?

    yum available -y
    yum available
    yum available list
    yum find available
  * yum list available


What approach could be used to construct a command, using yum, that would install multiple packages from enabled yum repositories?

    Use yum install then list all package names encapsulated within double quotation marks.
  * Use yum install then list the package names using a space delimiter.
    This can only be done using the graphical user interface system-config-packages.
    Use yum install then list the package names using a comma delimiter.
    This can only be done using scripts.


Which of the following commands will install a package that is not part of a yum repository?

    None of the above.
    yum install --disablerepos <package name>
  * yum localinstall <package name>
    yum localrepo <package name>
    yum local <package name>

Which of the following commands will list only documentation from the installed iptables rpm package?

    rpm -ql iptables
    rpm -qpd iptables
    rpm -q --documentation iptables
  * rpm -qd iptables
    rpm -qa iptables


To create a private repository you should proceed as follows: - Install the createrepo software package - Create a <directory> where files can be shared (via FTP or HTTP) - Create a subdirectory called Packages and copy all packages to be published in Packages - run createrepo -v <directory>

    FALSE
  * TRUE

Consider the following settings when configuring persistent static TCP/IP settings in a network interface configuration file. Of the settings listed which, if any, are incorrect?

    IPADDR=<ip address>
    NETMASK=<network mask>
 *  BOOTPROTO=dhcp
    ONBOOT=yes
    DEVICE=<device name>


Which of the following files is used to configure client side DNS settings?

 *  /etc/resolv.conf
    /etc/sysconfig/dns
    /etc/resolve.conf
    /etc/hosts
    /etc/host


To assign a persistent machine hostname to a machine, modify or add an entry to the following file.

*   /etc/sysconfig/network
    /etc/hosts
    /etc/sysconfig/hostname
    /etc/resolve.conf
    /etc/sysconfig/network-scripts/hostname


Which command would persistently enable routing in the kernel?

    echo 1 > /proc/sys/net/ipv4/ip_forward
    sysctl -w net.ipv4.ip_forward = 1
    /proc/sys/net/ipv4/ip_forward
 *  Add the following line to the /etc/sysctl.conf file: net.ipv4.ip_forward = 1
    Rebooting the system after any of these approaches will make the setting persistent.




Which of the following statements about SELinux permissive mode is TRUE?

    permissive mode will block all access to resources.
 *  permissive mode will not block access to a resource.
    permissive mode will allow access and does not log information.
    permissive mode of for testing purposes only.
    permissive mode will only block access to remote users and will log access information.


How do you check to see if SELinux is in 'enforcing' mode?

    selinuxchk
    getselinux
    cat /proc/selinux
    setenforce --check
 *  getenforce

How do you change the SELinux context of a file to its default context?

    setselinuxcon -d <filename>
    secon -d <filename>
    chmod -default-context <filename>
    chcon --defaults <filename>
 *  restorecon <filename>

To change to SELinux Booleans for a service you would use ???semanage boolean <service>???.

 *  FALSE
    TRUE

tip: " semanage boolean whatever_blabla -> bad command, too short ;)"

    getselogs
    selogchk
    There is no tool to analyze selinux log files.

    /etc/ntp/ntpd.conf
    /etc/ntpd.conf


Which critical mount option must be specified in /etc/fstab when persistently using filesystems on iSCSI storage?

    iqn
*   _netdev
    scsi

    masters
    forwarders
    root_hints
    recursion
    allow_recursion

(no time for find it in google ..., probably forwarders)
