   What is the purpose of the designated forwarder (DF) election in EVPN multihoming?

   • ATo select a PE to handle all unicast traffic for the segment.
   • BTo determine the active path for the Spanning Tree Protocol.
   • CTo select a single PE to forward BUM traffic for a multihomed Ethernet segment, preventing duplicate frames.
   • DTo elect a route reflector for the EVPN control plane.

   An administrator is configuring EVPN multihoming on a pair of Juniper Mist-enabled leaf switches. The access switch connects to both leaves. The administrator wants to ensure that the two leaf switches recognize the access switch's links as belonging to the same multihomed segment. What must be configured identically on both leaves?

   • AThe route distinguisher (RD) for the EVPN instance
   • BThe BGP peer group name
   • CThe Ethernet Segment Identifier (ESI) on the interfaces facing the access switch
   • DThe local IP address used for the EVPN overlay

   In an EVPN all-active multihoming setup, two leaf switches are connected to the same access switch. A host behind the fabric sends traffic to a server connected to the access switch. How does the fabric decide which leaf switch receives the traffic from the host?

   • AThe designated forwarder (DF) for the segment receives all traffic
   • BThe leaf switch that advertised the MAC route for the server receives the traffic
   • CThe traffic is sent to the leaf with the lower IP address
   • DThe remote leaf load-balances the traffic across both leaf switches based on a hash of packet headers

   What is the role of the Ethernet Segment Identifier (ESI) in EVPN multihoming?

   • AIt is used to select the route reflector for the EVPN control plane.
   • BIt is used to assign IP addresses to the multihomed links.
   • CIt uniquely identifies a multihomed link or Ethernet segment shared by multiple PE devices.
   • DIt identifies the MAC address of the access switch.

   What is a primary benefit of using EVPN multihoming in a campus fabric architecture?

   • AIt automatically configures all switches in the fabric without any manual intervention.
   • BIt eliminates the need for any Layer 2 control protocol in the fabric.
   • CIt increases the bandwidth of a single link by combining multiple physical links into one logical link.
   • DIt provides redundant connectivity from an access switch to multiple aggregation switches, improving link and node resilience.
