Which term describes the ability to group two or more physical network connections into a single logical link to improve throughput and reliability?

• A. NIC Teaming
• B. Network Topology
• C. NetBIOS
• D. Network Monitor

Answer: (A)

Grouping two or more physical network connections into a single logical link is NIC teaming, also known as link aggregation or bonding. The idea is to treat multiple NICs as one combined path so you can send traffic across several interfaces, which boosts overall available bandwidth and provides redundancy. With NIC teaming, traffic can be distributed across the NICs (load sharing), so multiple connections contribute to throughput, and if one link or NIC fails, the others keep the connection alive (fault tolerance). In practice, the effectiveness depends on how the aggregation is configured and whether the switch supports compatible techniques (like LACP) to form a true port-channel. The other terms don’t capture this concept: network topology refers to the layout of devices, NetBIOS is a name service, and a network monitor is a traffic-capturing tool.
