Consider the exhibit.

Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:

This scenario describes all-active Layer 2 EVPN multi-homing with a host connected through a LAG to Leaf1 and Leaf2. The LAG subinterface is associated with the MAC-VRF on both participating leaves, and the Ethernet Segment ES-1 is configured for all-active multi-homing. In all-active operation, both leaf routers can be active attachment points for host-originated traffic, and remote traffic can use EVPN multi-homing mechanisms to reach the segment. Option D is false because the host does not know or use the EVPN Designated Forwarder state when sending BUM traffic. The host forwards over its LAG based on its local LAG hashing and LACP behavior. DF election is an EVPN PE-side mechanism used mainly to control which PE forwards BUM traffic from the EVPN overlay toward the Ethernet Segment, preventing duplicate delivery to the multihomed access network. The host itself does not selectively forward all BUM traffic toward the DF. That distinction is critical: DF controls overlay-to-segment replication, while the host's LAG controls host-to-leaf link selection. Reference: all-active L2 EVPN multi-homing, host LAG behavior, DF election scope, BUM forwarding.
