NEW QUESTION # 67
What option in the client configuration file would tell OpenVPN to use a dynamic source port when making a connection to a peer?

A. src-port
B. nobind
C. source-port
D. remote
E. dynamic-bind

Answer: B

Explanation:
Explanation
The option that would tell OpenVPN to use a dynamic source port when making a connection to a peer is nobind. This option instructs OpenVPN to not bind to a specific local port number, but instead use an ephemeral port number chosen by the operating system. This allows multiple OpenVPN instances to connect to the same remote server or peer without port conflicts. The other options are either invalid or have different meanings:
src-port: This is not a valid OpenVPN option and will cause an error.
remote: This option specifies the host name or IP address and port number of the remote server or peer to connect to. It does not affect the source port of the client.
source-port: This is not a valid OpenVPN option and will cause an error.
dynamic-bind: This is not a valid OpenVPN option and will cause an error.

NEW QUESTION # 70
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?

A. Add echo 1 > /proc/sys/net/ipv4/ip_forward to the root user login script
B. In /etc/sysconfig/iptables-config add ipv4.ip_forward = 1
C. In /etc/sysct1.conf change net.ipv4.ip_forward to 1
D. Add echo 1 > /proc/sys/net/ipv4/ip_forward to any user login script
E. In /etc/rc.local add net.ipv4.ip_forward = 1

Answer: C

Explanation:
Explanation
The /etc/sysct1.conf file is used to configure kernel parameters at runtime. The net.ipv4.ip_forward parameter controls whether IP packet forwarding is enabled for IPv4. Setting it to 1 enables packet forwarding, while setting it to 0 disables it. This setting is applied at boot time and persists across system restarts. The other options are either incorrect or temporary solutions that do not survive a reboot. References: LPIC-2 201 exam objectives, LPIC-2 201-450 Exam Prep: Network Configuration
