Why each option
This question asks to identify which SD-WAN load balancing methods utilize interface weight values to distribute network traffic.
Source IP load balancing distributes traffic based on the source IP address, typically using hashing, and does not directly use interface weight for distribution.
Spillover load balancing prioritizes a primary interface until its capacity is met, then directs excess traffic to secondary interfaces, which is not primarily based on interface weight for continuous distribution.
Volume-based load balancing distributes traffic across interfaces based on their assigned weight, where interfaces with a higher weight are configured to handle a proportionally larger volume of data.
Session-based load balancing uses interface weight to distribute new sessions proportionally among available links, ensuring that interfaces with higher weights receive a greater share of new connection requests.
