Selected Answer: A

First, FortiGate uses the most specific route, which is the one with the longest netmask (smallest subnet). If there are two or more routes with the same longest netmask, the device selects the one with the shortest distance. After that, FortiGate uses the lowest metric as the tiebreaker for dynamic routes. In the case of static routes, FortiGate uses the lowest priority instead. If there are multiple routes with the same netmask, distance, metric, and priority, FortiGate shares the traffic among all of them. This is called equal-cost multi-path (ECMP). ECMP is supported for static, BGP, and OSPF routes. Pagina 363 Network_Security_Support_Engineer_7.4_Study_Guide
