In this scenario, what must be corrected to solve the connectivity problem?

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?
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 . 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.
D . 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.
