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 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
• B.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
• 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 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

Your Oracle Linux server has a network interface eth0 but the ifcfg-eth0 file is missing from the /etc/sysconfig/network-scripts directly.
To set the IP address for the interface, you run this command as root: [root@station1]# ifconfig eth0 192.168.0.1 up
What is the effect of the command?

• A.The IP address 192.168.0.1 is assigned to eth0, but the interface is not activated until the network service is restarted.
• B.The IP address 192.168.0.1 is assigned to eth0, but the interface is not activated until the network service is reloaded.
• C.The IP address 192.168.0.1 is assigned to echo with the default netmask for that address, and the interface is activated immediately.
• D.The IP address 192.168.0.1 is not assigned to eth0 because the netmask is not specified.
