   An administrator is configuring EVPN multihoming on two Juniper Mist leaf switches. They have configured the same ESI on the interfaces facing the access switch, but the two leaves are not forming the EVPN multihoming adjacency. What is the most likely cause?

   • ASTP is blocking the interfaces
   • BThe access switch is not configured with the same ESI
   • CThe ESI value is too long
   • DBGP EVPN is not enabled or the EVPN instance is not configured on both leaves

   A network team is evaluating EVPN multihoming for a campus fabric to improve resilience. They currently use STP to prevent loops. What is the primary benefit of EVPN multihoming over STP in this scenario?

   • AIt eliminates the need for any loop-prevention mechanism
   • BIt simplifies configuration by removing the need for BGP
   • CIt allows all redundant links to be active simultaneously, improving bandwidth utilization
   • DIt provides faster convergence than STP but still blocks redundant links

   What is a required configuration step for EVPN multihoming on Juniper Mist-enabled switches?

   • AConfiguring the same ESI on all switches that share the multihomed Ethernet segment.
   • BConfiguring a unique ESI on each switch in the fabric.
   • CEnabling STP on all switches to prevent loops.
   • DDisabling BGP on all switches in the fabric.

   An administrator is configuring EVPN multihoming on two Juniper Mist leaf switches. They have assigned the same ESI to the interfaces facing the access switch. What additional configuration is required on the leaf switches to enable the EVPN multihoming functionality?

   • AEnable BGP EVPN and configure the EVPN instance with the ESI
   • BEnable LACP on both leaf interfaces
   • CConfigure the same IP address on both leaf interfaces
   • DEnable STP on the interfaces to prevent loops

   In an EVPN multihoming setup, a link between an access switch and a leaf switch fails. The access switch is still connected to a second leaf. How does the network detect this failure and what is the immediate impact on traffic?

   • AThe access switch must manually switch to the second leaf
   • BThe failure is detected by the DF election process, which blocks all traffic until re-election
   • CThe leaf detects the link failure via BFD and withdraws its routes; traffic is re-routed to the remaining leaf
   • DThe ESI is changed to a new value to trigger re-convergence
