Link Aggregation: Involves combining multiple physical network interfaces into a single logical interface. This creates increased bandwidth, improved fault tolerance, and load balancing, where traffic can be distributed across all links in the group. (CompTIA Server+ Objectives SK0-004: 2.4) Why other options are incorrect:
Most recently used algorithm: A concept used in memory management, not network traffic distribution.
Active-passive configuration: Used for failover with only one interface active at a time.
Failover: Ensures service continuity if an interface fails but does not inherently distribute load across multiple links.
