Final answer:
The query involves configuring a DB server to prevent it from initiating outbound connections on a specific network interface, NIC2. Firewall rules can be used to enforce this policy, enhancing network security and managing the traffic according to the server's environment needs.
Step-by-step explanation:
The question pertains to a scenario involving a DB server, or database server, and its network interface controller (NIC). Specifically, the instruction is that the server should not initiate outbound connections on a particular network interface, in this case, NIC2. This might be part of a network security policy to segregate traffic and control the flow of data within the server's environment.
To ensure that the DB server does not initiate outbound connections on NIC2, a network administrator could use firewall rules. The rules can be configured to block all outbound traffic originating from NIC2's IP address or to permit only essential services if necessary. This is to maintain network security by enforcing a strict outbound traffic policy on specified interfaces. For example, in a Unix-based system, one could use iptables or ufw (Uncomplicated Firewall) to set up these restrictions. The commands would explicitly deny any outgoing packets from NIC2, ensuring that the DB server follows the set policy.
