What is the purpose of interface bonding?

Interface bonding, also known as link aggregation, is a feature of the Gaia operating system that groups multiple physical network interfaces into a single logical interface. This serves two primary purposes. The first is High Availability, where one interface can take over if another fails (Active/Backup mode). The second is Load Sharing, where traffic is distributed across all interfaces in the bond (e.g., using LACP 802.3ad), which increases the total available throughput.

A. This is only partially correct. High availability is one of the two main purposes of bonding, but it omits the load-sharing function.
B. While a bonded interface can be used for synchronization traffic, this is not its fundamental purpose. Bonding is a general networking feature, not one specific to sync.
C. This is only partially correct. Load sharing for increased throughput is a key function, but this answer omits the high availability aspect.
