Examine the ssh connection and disconnection shown:

What is checked when the oracle user on the host FAROUT attempts to connect to the oracle user on the host WAYOUT on subsequent occasions? (Choose the best answer.)

• A. The ssh server on host WAYOUT, compares the public host key supplied by host FAROUT with the public host key that was saved in the /oracle/.ssh/known_hosts file on server WAYOUT
• B. The ssh server on host WAYOUT, compares the public host key supplied by host FAROUT with the public host key that was saved in the /oracle/.ssh/authorized_keys file on server WAYOUT
• C. Hosts FAROUT and WAYOUT swap public host keys and compare them to the keys that were saved locally in the /oracle/.ssh/known_hosts file
• D. The ssh client on host FAROUT, compares the public host key supplied by host WAYOUT with the public host key that was saved in the /oracle/.ssh/known_hosts file on server FAROUT
• E. The ssh client on host FAROUT, compares the public host key supplied by host WAYOUT with the public host key that was saved in the /oracle/.ssh/authorized_keys file on server FAROUT

Examine this extract from the /etc/ssh/sshd_config file:
passwordAuthentication no
What is the effect of this parameter settings on the use of openSSH commands on both the client and server?

• C. Passwords are not required and no ssh-keygen is required either. Only passphrase are required.

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