   You want to enable the border leaf device to send Type 5 routes of local networks to the border leaf device in another data center. What must be changed to the configuration shown in the exhibit to satisfy this requirement?

   • AAdd a VLAN configuration with an l3-interface to the tenant1 routing instance.
   • BMove vrf-target target: 65000:1 to the evpn hierarchy.
   • CChange :5001 in the route-distinguisher to :10010.
   • DAdd encapsulation vxlan to the evpn hierarchy.

   Select 3

   Which three statements are correct about symmetric IRB routing with EVPN Type 2 routes? (Choose three.)

   • AAn L3 interface (IRB) is required for each local VLAN.
   • BSymmetric routing requires MAC-VRF.
   • CSymmetric routing is less efficient than asymmetric routing.
   • DSymmetric routing supports the EVPN service VLAN bundle.
   • ESymmetric routing requires an extra transit VNI for each VRF.

   You are troubleshooting an IP fabric for your data center. You notice that your traffic is not being load balancing to your spine devices from leaf devices. Referring to the configuration shown in the exhibit, what must be configured to solve this issue?

   • AThe load-balance policy must have a from statement that matches on protocol bgp.
   • BThe multipath multiple-as configuration must be configured for each peer in the BGP spine group.
   • CThe load-balance policy must be applied as an export policy to your BGP spine group.
   • DThe load-balance policy must be applied to the forwarding table under the routing-options hierarchy.

8. Question 8 · 48 in bank

   You are using a single tenant data center with a bridged overlay architecture. In this scenario, how do hosts of the different virtual networks communicate with each other?

   • Ausing anycast gateway addresses configured on the leaf devices
   • Busing EVPN Type 5 routes
   • Coff-fabric using an external device
   • Dusing virtual gateway addresses configured on the spine

9. Question 9 · 48 in bank

   Which statement is correct about a collapsed fabric EVPN-VXLAN architecture?

   • AFully meshed back-to-back links are needed between the spine devices.
   • BBorder gateway functions occur on border leaf devices.
   • CIt supports multiple vendors in the fabric as long as all the spine devices are Juniper devices deployed with L2 VTEPs.
   • DUsing Virtual Chassis at the leaf layer increases resiliency.
