Question 1
On a Linux router, packet forwarding for IPv4 has been enabled. After a reboot, the machine no longer forwards IP packets from other hosts. The command:
echo 1 > /proc/sys/net/ipv4/ip_forward
temporarily resolves this issue.
Which one of the following options is the best way to ensure this setting is saved across system restarts?
- Add echo 1 > /proc/sys/net/ipv4/ip_forward to the root user login script
- Add echo 1 > /proc/sys/net/ipv4/ip_forward to any user login script
- In /etc/sysct1.conf change net.ipv4.ip_forward to 1
- In /etc/rc.local add net.ipv4.ip_forward = 1
- In /etc/sysconfig/iptables-config add ipv4.ip_forward = 1
Correct answer: C

Question 5
Which of the statements below are correct regarding the following commands, which are executed on a Linux router? (Choose two.)
- Packets with source or destination addresses from fe80::/64 will never occur in the FORWARD chain
- The rules disable packet forwarding because network nodes always use addresses from fe80::/64 to identify routers in their routing tables
- ip6tables returns an error for the second command because the affected network is already part of another rule
- Both ip6tables commands complete without an error message or warning
- The rules suppress any automatic configuration through router advertisements or DHCPv6

Question 9
When the default policy for the netfilter INPUT chain is set to DROP, why should a rule allowing traffic to localhost exist?
- All traffic to localhost must always be allowed
- It doesn’t matter; netfilter never affects packets addressed to localhost
- Some applications use the localhost interface to communicate with other applications
- syslogd receives messages on localhost
- The iptables command communicates with the netfilter management daemon netfilterd on localhost to create and change packet filter rules
Correct answer: C
