質問 3：
An EVPN-signaled VXLAN overlay has been deployed in the network shown in the exhibit. An EVPN LAG has been configured to connect host1 to the network, and device leaf1 has been elected as the designated forwarder.

In this scenario, which statement is true?
A. The Ieaf3 device will only receive an advertisement to the LAG segment from leaf1.
B. Broadcast packets sent from host2 will not be forwarded to Ieaf2.
C. The Ieaf3 device can utilize both leaf1 and Ieaf2 to forward unicast packets from host2 to host1.
D. An ICCP control link must be configured between leaf1 and Ieaf2.
正解：A

質問 4：

Which two configuration parameters would be applied to accomplish this task? (Choose two.)
A. Configure auto-export under both routing instances.
B. Apply policy irb-A under instance Tenant_c and apply policy irb-c under instance Tenant_A as import policies.
C. Apply policy irb-A under instance Tenant A and apply policy irb-c under instance Tenant_c as export policies.
D. Configure vrf-table-label under both routing instances.
正解：B,D

質問 6：
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 host will transit a VXLAN tunnel to spine or spine2 then a VXLAN from spine1 or spine2 to leaf 3.
B. An IRB interface must be configured on device leaf1 and leaf2.
C. Traffic from host1 to host2 will transmit the VXLAN tunnel from leaf1 to leaf3.
D. An IRB interface must be configured on devices spine1 and spine2.
正解：C,D

質問 7：

- lower latency with East-West traffic.
Which architecture should you use in this scenario?
A. bridge overlay architecture
B. centrally-routed bridging architecture
C. edge-routed bridging architecture
D. collapsed spine architecture
