The Dynamic Host Configuration Protocol (DHCP) is a network protocol that dynamically assigns IP addresses and other network configuration parameters to devices on a network.
To ensure proper functionality of the DHCP server, two ports must be allowed on the server's local firewall:
Port 67: This port is used by the DHCP server to listen for requests from DHCP clients.
Port 68: This port is used by DHCP clients to send requests to the DHCP server.
Therefore, options D and E, which are ports 67 and 68 respectively, are the correct answers.
Options A and B, which are ports 20 and 21 respectively, are used by the File Transfer Protocol (FTP).
Option C, which is port 53, is used by the Domain Name System (DNS).
Option F, which is port 389, is used by the Lightweight Directory Access Protocol (LDAP).
Since these protocols are unrelated to DHCP, they are not required for the proper functionality of the DHCP server, and thus should not be allowed on the server's local firewall.
