Select 2
Options
A By default, the QFX5100 will send copies of the multicast packets to all locally attached devices in the same VLAN.
B By default, the QFX5100 will send copies of the multicast packets to locally attached devices in the same VLAN that are interested receivers only.
C By default, the QFX5100 will encapsulate the multicast packets in VXLAN and forward them to remotely connected VTEPs with interested receives only.

Question
You have built a mixed-mode VCF consisting of two QFX5100-24Qs as spines, two QFX5100-48S as leaf nodes, and one EX4300 as a leaf node. The VCF is working for all devices, except the EX4300 40GbE fabric links will not join the VCF. In this scenario, what must be corrected to solve the connectivity problem?
Options
A Reboot all of the VCF members.
B Power off all of the VCF members and power up the spines before powering up the leafs.
C Turn off authonegotiation on the EX4300 and the attached spine interfaces, and then use the request virtual-chassis vc-port set command on the spine ports connected to the EX4300.
D Zeroize the EX4300, cleat all the tables with the clear ethernet-switching tables command on all members, and reissue the request virtual-chassis mixed-mode command.
