You are implementing VXLAN broadcast domains in your data center environment. Which two statements are correct in this scenario? (Choose two.)

• A.The VNI must match the VLAN tag to ensure that the remote VTEP can decapsulate VXLAN packets.
• B.A VXLAN packet does not contain a VLAN ID.
• C.Layer 2 frames are encapsulated by the source VTEP.
• D.The VNI is a 16-bit value and can range from 0 through 16.777.215.

Referring to the exhibit, why is the active source field blank for the entry that uses the
00:0c:29:e8:b7:39 MAC address?

• A.This entry is associated with a multicast EVPN route.
• B.The EVPN route for this host does not have a valid next hop.
• C.The ARP lookup for this host has failed.
• D.The host for this entry is locally connected to leaf1.

You are asked to build out the VXLAN control plane.
In this scenario, which two protocols provide this capability? (Choose two.)

• A.IS-IS
• B.PIM-SM
• C.MBGP
• D.OSPF

Referring to the exhibit, when Host A sends an ARP request for Host B's IP address, which Junos feature does leaf1 require to send an ARP response back to Host A without having to send a broadcast frame over the fabric?

• A.proxy NDP
• B.DAD
• C.GARP
• D.proxy ARP

Why is a designated forwarder required in a multihomed CE-to-PE VXLAN environment using EVPN signalling?

• A.The designated forwarder is required to prevent flooding of MAC addresses to multihomed hosts.
• B.The designated forwarder is required to prevent a traffic storm from being received on multihomed hosts.
• C.The designated forwarder is required to prevent duplicate packets from being received on multihomed hosts.
• D.The designated forwarder is required to prevent packets from looping between the PEs.
