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

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

A web server on HOST01 is listening on port 80.
Examine the IPTABLES rule shown:
[root@host01 ~] # iptables -L INPUT
Chain INPUT (policy ACCEPT)
targetportoptsourcedestination
ACCEPTtcp- - anywhereanywheretcp dpt:http
Another rule is then added:
[root@host01 ~] # iptables -A INPUT -P tcp - - dport 80 -j REJECT
What is the effect of this command on subsequent attempts to access the web server on HOST01 using port
80?

• A.New connection attempts timeout.
• B.New connection attempts are refused and the client informed of the refusal.
• C.New connection attempts succeed until a reload of the firewall rules.
• D.New connection attempts always succeed.
