Which two functions does NIC teaming support for sharing bandwidth equally among multiple VMs?

• A. Load Balancing and Fault Tolerance
• B. High Availability and Security
• C. Resource Allocation and Traffic Monitoring
• D. Dynamic IP Changes and Locality Awareness

Answer: (A)

NIC teaming is a solution that allows multiple network interface cards (NICs) to work together to increase network throughput and provide redundancy. The capability for load balancing is key to equalizing bandwidth among virtual machines (VMs). By distributing network traffic across the teamed NICs, load balancing ensures that no single NIC becomes a bottleneck, leading to better performance and more efficient use of resources.

Fault tolerance is another critical function of NIC teaming. In this context, if one NIC fails, the other NICs can take over, maintaining network connectivity without interruption. This redundancy is crucial in environments that require high availability, as it minimizes downtime and ensures that network services remain accessible.

While the other options mention functions like high availability and security, resource allocation and traffic monitoring, or dynamic IP changes and locality awareness, they do not directly relate to efficient bandwidth sharing among VMs. Instead, load balancing and fault tolerance specifically address the need for optimal network traffic distribution and resilience against hardware failures, making them the correct functions supported by NIC teaming in this context.
