Which networking configuration can improve communication redundancy on a server?

Establishing a NIC team is an effective way to improve communication redundancy on a server. This configuration involves combining multiple network interface cards (NICs) into a single logical interface. By doing this, if one NIC fails, the other NICs can continue to handle network traffic without interruption. This redundancy ensures continuous network availability and can enhance bandwidth by load balancing traffic across the teamed NICs.

In contrast, configuring a server with a single NIC would not provide redundancy, as there would be a single point of failure. Similarly, using static routes does not inherently provide redundancy; it simply defines specific paths for data transmission without any failover capability. Deploying multiple DHCP servers is aimed at ensuring availability of IP address allocation but does not directly contribute to communication redundancy for server connections. Thus, NIC teaming is the best choice for enhancing redundancy in server communications.
