A network administrator wants to balance the amount of data between two networking cards. Which of the following can be used for two or more networking cards?

NIC bonding aggregates multiple physical NICs into a single logical interface, allowing the operating system or switch to distribute outbound and inbound traffic across the member adapters. This provides both load balancing of bandwidth and fault tolerance if one NIC fails, and it requires a compatible switch supporting LACP (IEEE 802.3ad) on the other end for active-active configurations.

A proxy server forwards client requests on behalf of users and can cache content - it operates at the application layer and has no function in balancing traffic between physical NICs.

Firewall ACLs define permit and deny rules for traffic flows - they control access policy but do not distribute traffic across multiple network interface cards.

VLANs logically segment a network at Layer 2 - they partition broadcast domains but do not combine or load-balance traffic across multiple physical NICs.
