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.)
Answer(s): A,B
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.
EVPN Overview
You have a two spine and four leaf CRB topology and you must ensure that the hosts connected to the leaf devices have reachability to all IRB interface addresses, including the local spine IRBaddresses, and the virtual gateway address.Which two configuration parameters must be used to accomplish this task? (Choose two.)
Answer(s): B,D
B) Configure virtual-gateway-accept-data under the IRB interface. This configuration is necessary to ensure that the IRB interfaces on the spine devices can handle traffic destined to the virtual gateway IP address.D) Configure proxy-macip-advertisement under the IRB interface. This enables the advertisement of proxy MAC/IP routes to remote VTEPs. This is essential in a CRB (Centralized Routing and Bridging) topology to ensure that all hosts, including those connected to the spine devices, have reachability to all IRB interface addresses.

You are troubleshooting a connectivity issue across a VXLAN overlay network. In the exhibit, you are using the ping overlay command from a local VTEP residing on a OFX 5120 to a remote VTEP residing on a separate QFX5120.What is the problem in this situation?
Answer(s): C
Which event triggers the generation of a EVPN type-4 route?
Answer(s): D
An EVPN Type-4 route, also known as an Ethernet Segment (ES) route, is generated when a new Ethernet Segment Identifier (ESI) is configured. The ESI represents an Ethernet segment for multi- homing purposes in EVPN. When a new ESI is configured on an interface, it triggers the generation of an EVPN Type-4 route to advertise the Ethernet segment's existence and its multi-homed state to other VTEPs in the EVPN instance. This helps in providing redundancy and load balancing in a multi- homed EVPN environment.
