You are troubleshooting an L3VPN that is part of an EVPN/MPLS DCI. You notice that the EVPN overlay BGP session toward 10.29.50.4 is unable to establish. Why is the BGP session failing to establish?
Refer to the exhibit. Referring to the exhibit, which two statements are correct? (Choose two.)
Which two statements about a DHCP relay in an EVPN-VXLAN fabric are correct? (Choose two.)
Which two combinations are supported when configuring a Virtual Chassis Fabric? (Choose two.)
Which protocol is used between VCF member devices to create a loop-free topology?
Which two statements are true Virtual Chassis? (Choose two.)
Referring to the exhibit, each node in the IP fabric is peering to its directly attached neighbor using EBGP. Each node is peering using physical interface IP addresses. Leaf 2 and Leaf 3 are advertising the 10.1.1/24 network into EBGP. Spine 2 must be configured so that it can load- share traffic destined to the 10 1.1/24 network over both next-hop A and next-hop B. Which two actions must be performed to accomplish this task? (Choose two.)
You are asked to enable plug-and-play line card switches in an active VCF without making any future Junos configuration charges. You are also required to ensure that all new line card are automatically upgrade to the correct Junos version without any manual intervention. In this scenario, which two actions will accomplish this task? (Choose two.)
You work in a data center where VMs and hosts are frequently moved. Your design needs to eliminate inefficient traffic flows. In this scenario, which two solutions will satisfy this requirement? (Choose two.)
Which two statements are correct about VXLANs? (Choose two.)

You are asked to implement VXLAN in your data center network. You must choose between implementing EVPN signaling and multicast signaling. Which two statements are correct in this scenario? (Choose two.)

A.
EVPN signaling reduces ARP flooding and multicast signaling does not.
Answers
A.
EVPN signaling reduces ARP flooding and multicast signaling does not.
B.
EVPN signaling propagates MAC addresses across the network and multicast signaling does not.
Answers
B.
EVPN signaling propagates MAC addresses across the network and multicast signaling does not.
C.
EVPN signaling uses a standards-based protocol and multicast signaling does not.
Answers
C.
EVPN signaling uses a standards-based protocol and multicast signaling does not.
D.
EVPN signaling enables distributed Layer 3 gateways and multicast signaling does not.
Answers
D.
EVPN signaling enables distributed Layer 3 gateways and multicast signaling does not.
Suggested answer: A, B

Explanation:

A) EVPN signaling reduces ARP flooding, while multicast signaling does not. EVPN uses BGP to distribute MAC address information, which can also include IP address bindings, thereby eliminating the need for ARP flooding across the VXLAN overlay. B. EVPN signaling propagates MAC addresses across the network, while multicast signaling does not. In an EVPN environment, MAC address advertisements are distributed via BGP EVPN routes, enabling efficient and scalable MAC address learning and distribution.
