What are three benefits of EVPN that would improve the current E-line, E-LAN, and E-Tree delivery? (Choose three.)

• A.native support for multihoming
• B.integrated L2/L3 connectivity
• C.greater Multiprotocol Label Switching scale
• D.network resiliency between edge nodes
• E.efficient security provisioning

You must manually configure VXLAN on a QFX5100.
Which protocol is required to perform this task?

• A.EBGP
• B.MSDP
• C.DVMRP
• D.PIM

You are building a mixed-mode Virtual Chassis with two QFX5100-24Qs, four QFX3500-
48s, two EX4600-40Fs and two EX4300-48Ts. The Virtual Chassis will not provision.
In this scenario. which statement is correct?

• A.Mixed-mode Virtual Chassis only allows for eight members.
• B.EX4600s are only allowed with EX4300s.
• C.EX4600s must be preprovisioned as the master and backup.
• D.QFX3500s are not allowed in mixed mode.

Which three BGP messages pass EVPN information between devices? (Choose three.)

• A.notification messages
• B.open messages
• C.route-refresh messages
• D.keepalive messages
• E.update messages

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?

• A.Edge1's routing table must contain an IP route to both Leaf1 and Leaf2.
• B.Edge1 must be configured for MP-BGP using L3VPN signaling.
• C.Edge1 must be configured for MP-BGP using EVPN signaling.
• D.Edge1 must be configured for BGP labeled unicast on its PE1-facing interface.
