Which line in the OpenVPN server.conf file supplies a DNS server for DHCP clients?

• A. push "dhcp-option DNS 10.142.232.4"
• B. push "dhcp DNS 10.142.232.4"
• C. push "option DNS 10.142.232.4"
• D. push "dhcpoption DNS 10.142.232.4"

Answer: (A)

The correct answer is the line that uses the syntax `push "dhcp-option DNS 10.142.232.4"`, as it accurately specifies the command to push a DNS server option to DHCP clients connecting to the OpenVPN server. In OpenVPN configuration, the `push` directive is used to send configuration options to clients, and the `dhcp-option` specifies options that are typically used by DHCP clients, such as DNS server addresses. The format follows a specific structure: `push "dhcp-option <option-type> <value>"`, where `<option-type>` can be various DHCP-related settings, and `<value>` is the specific configuration setting being provided. In this case, `DNS` is the option being provided, followed by the IP address of the DNS server. Other options do not conform to the correct syntax required by OpenVPN. For instance, the use of "dhcp" alone without "option" is incorrect, and similarly for "option" without the correct preceding structure. Additionally, incorrectly formatted terms such as "dhcpoption" and the lack of quotes or correct structure lead to invalid configurations. Thus, understanding the correct syntax and use of directives in OpenVPN is crucial to properly set up services that rely
