• D. Ensure that the newly instead card's MAC addresses are present in the DHCP configuration for ZTP.

Exhibit:

Devices spine1 and spine have been configured as distributed Layer 3 gateways in the VXLAN topology, and devices leaf1 and leaf3 have been configured as layer 2 gateways. Device host must be able to communicate with device host?
Which two statements are true? (Choose two.)

• A. Traffic from host1 to host2 will transmit the VXLAN tunnel from leaf1 to leaf3.
• B. An IRB interface must be configured on devices spine1 and spine2.
• C. An IRB interface must be configured on device leaf1 and leaf2.
• D. Traffic from host1 to host will transit a VXLAN tunnel to spine or spine2 then a VXLAN from spine1 or spine2 to leaf 3.

Your manager asks you to secure ARP and DHCP traffic across your local Ethernet links In this scenario, which technology will accomplish this task?

• A. A firewall filter
• B. MAC sec
• C. SSL
• D. IPsec

Which two statements define the use of route targets and route distinguishers in an EVPN? (Choose two.)

• A. Route distinguishers identify the VRF into which the route should be placed
• B. Route targets identify the VRF into which the route should be placed
• C. Route distinguishers ensure that routes from different client remain unique within the data center domain
• D. Route targets ensure that routes from different clients remain unique within the data center domain

You are logged in to Leaf 1. When examining the routing table, you notice that you have no routes from Leaf 2.

Referring to the exhibit, which two commands would you use to troubleshoot the problem? (Choose two.)

• A. From Spine 1, issue the show route advertising-protocol bgp 172.16.1.2 command.
• B. From Leaf 2, issue the show route advertising-protocol bgp 172.16.1.2 command.
• C. From Spine 1, issue the show route advertising-protocol bgp 172.16.1.1 command.
• D. From Leaf 1, issue the show route receive-protocol bgp 172.16.1.1 command.
