• Question 113:

  You are about to switch a Red Hat Enterprise Linux 6 (RHEL6) system from the Red Hat Network to the Unbreakable Linux Network (ULN).

  Consider this output:

  # rpm 璹a *rhn*

  rhnlib-2.5.22-12.e16.noarch yum-rhn-plugin-0.9.1-36.e16.noarch rhn-setup-1.0.0-73.e16.noarch rhn-client-tools-1.0.0-73.e16.noarch rhn-check-1.0.0-73.e16.noarch rhnsd-4.9.3-2.e16.x86_64

  Identify four minimum steps that you should perform to successfully switch this system from RHN to ULN.

  A. Create a ULN account if it doesn't exist already.
  B. Ensure you have a valid Oracle Linux support agreement.
  C. Install the uln_register.tgz package.
  D. Install the uln_register.tgz and uln_register-gnome.tgz packages.
  E. Run the uln_register command as the root user and answer the prompts.
  F. Install the Unbreakable Enterprise kernel (UEK).
  G. Run the yum update command.
  H. Reboot your system.
  A. Create a ULN account if it doesn't exist already.
  C. Install the uln_register.tgz package.
  E. Run the uln_register command as the root user and answer the prompts.
  F. Install the Unbreakable Enterprise kernel (UEK).

  Switching from RHN to ULN

  This procedure is for a Red Hat Enterprise Linux 6 system.

  If you have an Oracle Linux 6 system that is registered with the Red Hat Network (RHN), you can use theuln_register utility to register.

  (A)You must have a ULN account before you can register a system with ULN.

  To register your system with ULN instead of RHN:

  1. (C) Download the uln_register.tgz package from http://linux-update.oracle.com/rpms to a temporary directory.

  2. xtract the packages using the following command. # tar -xzf uln_register.tgz

  3. Change to the uln_migrate directory and install the registration packages.

  4. # cd ./uln_migrate # rpm -Uvh *.rpm

  5. Run the uln_register command. # uln_register

  6. Follow the instructions on the screen to complete the registration. The uln_register utility collects information about your system and uploads it to Oracle.

• Question 114:

  Which two conditions should be met in order to successfully configure an openssh client on Oracle Linux?

  A. The openssh-server package must not be installed.
  B. The openssh package must be installed.
  C. The sshd daemon must not be started.
  D. The openssh-client package must be installed.
  E. The ssh-agent must be started.
  F. ssh keys must be generated by any user using the ssh client.
  B. The openssh package must be installed.
  D. The openssh-client package must be installed.

  ---

  To connect to an OpenSSH server from a client machine, you must have the openssh-clients and openssh packages installed on the client machine.

• Question 115:

  B. to allow a non-root user to bring a network interface up or down using the ifconfig command
  C. to allow a non-root user to bring a network interface up or down using the ethtool command
  D. to allow a non-root user to bring a network interface up or down using the ifup, ifdown, and ifconfig commands

• Question 119:

  Which three statements are true about the User Private Group scheme in Oracle Linux?

  B. The umask for the jules user is 002 in /etc/bashrc
  C. Users belonging to a group to which user jules also belongs, are automatically able to write to the private group belonging to the jules user.
  D. If a user jules is added with the user add jules command, a group called jules is also added. but no other user may be a member of that group.
  E. A directory owned by a group to which several users belong, and which has the setgid fa turned on, has shared write access to all members of the group.
  F. The User private Group scheme is enabled by default in Oracle Linux.
  D. If a user jules is added with the user add jules command, a group called jules is also added. but no other user may be a member of that group.
  E. A directory owned by a group to which several users belong, and which has the setgid fa turned on, has shared write access to all members of the group.
  F. The User private Group scheme is enabled by default in Oracle Linux.

  ---

  DF (not A): By default, Oracle Linux implements the user private group (UPG) scheme where adding a user account also creates a corresponding UPG with the same name as the user, and of which the user is the only member.

  E: When setgid permission is applied to a directory, files that were created in this directory belong to the group to which the directory belongs, not the group to which the creating process belongs. Any user who has write and execute permissions in the directory can create a file there. However, the file belongs to the group that owns the directory, not to the user's group ownership.
