D. Link aggregation: Link aggregation, also known as Ethernet bonding, link bundling, or port trunking, is the process of combining multiple network connections in parallel to increase throughput and redundancy. When a connection had previously worked successfully, link aggregation protocols such as LACP (Link Aggregation Control Protocol) or PAgP (Port Aggregation Protocol) may prioritize using that connection again, provided it's available and operational. This is typically achieved through load-balancing algorithms that take into account the status of each link and its past performance,. effectively prioritizing connections that have previously demonstrated reliability and success.
