You are deploying MC-LAG as shown in the exhibit.
Which statement is correct when using active/standby mode?
A. A spanning tree protocol should be used to avoid Layer 2 loops between Server A and both switches.
B. VCCP is used to exchange MAC addresses between MC-LAG peers.
C. All traffic from Server A to Host 1 will traverse the link between Server A and ex2.
D. Only ICCP control traffic is allowed through the ICL-PL connection.
Answer: C
Question #12 (Topic: )

Referring to the exhibit, PE1 and PE2 are acting as MPLS Layer 3 VPN PEs to provide the
DCI between DC1 and DC2, which are IP Fabrics. Leaf 1 and Leaf 2 are QFX5100 Series
devices acting as VXLAN Layer 2 Gateways using EVPN signaling for the same VXLAN
segment.
Which statement is correct about the Edge1 device in this scenario?

Which statement is correct about the Edge1 device in this scenario?
A. Edge1 must be configured for MP-BGP using EVPN signaling.
B. Edge1 must be configured for MP-BGP using L3VPN signaling.
C. Edge1 must be configured for BGP labeled unicast on its PE1-facing interface.
D. Edge1’s routing table must contain an IP route to both Leaf1 and Leaf2.
Answer: D
Question #13 (Topic: )
You must manually configure VXLAN on a QFX5100.
Which protocol is required to perform this task?
Which protocol is required to perform this task?
A. DVMRP
B. EBGP
C. PIM
D. MSDP
Answer: C
Question #14 (Topic: )
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?

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.
Answer: D
Question #15 (Topic: )
What are two methods used to scale an IBGP IP Fabric? (Choose two.)
A. spanning tree
B. redundant trunk groups
C. route reflection
D. confederations
Answer: C,D
