Question 7

Referring to the exhibit, each leaf node is a QFX5100 acting as a VXLAN Layer 2 Gateway using EVPN signaling. Leaf 2 and Leaf 3 are both attached to the same EVPN Ethernet segment. Leaf 2 has been elected the designated forwarder for VLAN 200 on that Ethernet segment.
In this scenario, which two actions will Leaf 1 perform with the broadcast Ethernet frame received from Host A? (Choose two.)

A. Leaf 1 will send a VXLAN encapsulated copy of the Ethernet frame to Leaf 2 only. B. Leaf 1 will strip the VLAN tag from the Ethernet frame before encapsulating it in VXLAN. C. Leaf 1 will send a VXLAN encapsulated copy of the Ethernet frame to both Leaf 2 and Leaf 3. D. Leaf 1 will change the VLAN tag of the Ethernet frame to 200 before encapsulating it in VXLAN.
