About NIC teaming NIC teaming is the process of combining multiple network cards together for performance, load balancing, and redundancy reasons. Use NIC teaming to group two or more physical NICs into a single logical network device called a bond. NIC teaming is also called as Load Balancing FailOver (LBFO), bandwidth aggregation, traffic failover, and so on. Benefits of NIC teaming NIC teaming helps in: Load balancing — Outgoing traffic is automatically load balanced based on destination address between the available physical NICs. Fault tolerance — If one of the underlying physical NICs is broken or its cable is unplugged, server/target host detects the fault condition and automatically move traffic to another NIC in the bond.

C. NIC teaming NIC (Network Interface Card) teaming, also known as link aggregation or load balancing/failover (LBFO), is a method of grouping multiple network cards together to function as a single unit. In this case, the network engineer has already connected two network cables from the server to a switch and configured Link Aggregation Control Protocol (LACP) on the switch. LACP is a method of grouping two or more physical Ethernet links to become one logical Ethernet link to increase bandwidth and provide redundancy. The next step is to configure the server side to recognise and utilise multiple network connections as a single connection. This can be achieved by configuring NIC teaming on the server.

In this scenario, the network engineer has connected two network cables from the server to a switch stack and configured LACP on the switchports. To take advantage of the increased bandwidth, the server needs to be configured with NIC teaming, which will allow it to use both network interfaces simultaneously. Load balancing, multipathing, and clustering are related but different techniques that may also be used to increase server performance and/or availability.

Bond multiple NICs: Bonding multiple NICs together can provide a single, high-speed connection to the server, effectively increasing the available bandwidth.

NIC teaming. Load Balancing would suggest multiple servers. Also the question stated two network cables was connected from the server which suggest there is two NICs.

Link Aggregation Control Protocol (LACP) is implemented specifically to enable port aggregation (AKA NIC teaming).

The answer is nic teaming because the question emphasize on switch configuration.

I also voted for NIC teaming but can someone explain why it's not load balancing?
