Which networking feature consolidates multiple physical network interfaces into a single logical interface to improve throughput and provide fault tolerance?

• A. Virtual NIC
• B. NIC Teaming
• C. VPN
• D. Trunk port

Answer: (B)

NIC teaming is the technique of merging multiple physical network interfaces into one logical channel to boost overall throughput and provide fault tolerance. By combining adapters, traffic can be distributed across several NICs, increasing the effective bandwidth, and if one path or connection fails, the remaining NICs can continue handling traffic, keeping the connection active. This often uses standards like 802.3ad/LACP and requires either switch support (-link aggregation) or a switch-independent setup, depending on the environment. This concept is distinct from a virtual NIC, which is just a single virtual interface for a VM; a VPN, which creates a secure tunnel over a network; and a trunk port, which carries multiple VLANs on a switch link.
