質問 5：
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 6：
Referring to the exhibit,

you have a data center in which only the spine devices are using EVPN and VXLAN. The leaf nodes are multihomed in active-active mode to the spine nodes through ESI LAG interfaces. In this design, a link failure on the interface connecting the spine nodes would also cause all traffic from the spine to the leaf nodes to drop.
In this scenario, which command configured on which nodes would solve this problem?
A. the set protocols evpn no-core-isolation command on the leaf nodes
B. the set protocols evpn no-core-isolation command on the spine nodes
C. the disable protocols evpn no-core-isolation command on the leaf nodes
D. the disable protocols evpn no-core-isolation command on the spine nodes
正解：D

質問 7：
Referring to the exhibit, you have a data center with two PODs. Seamless EVPN-VXLAN stitching is used to facilitate communication between the PODs.

Which three statements are true in this scenario? (Choose three.)
A. A VXLAN tunnel can form between S1 and S2.
B. AVXLAN tunnel can form between L1 and L2.
C. AVXLAN tunnel can form between L2 and S3.
D. AVXLAN tunnel can form between L1 and L4.
E. AVXLAN tunnel can form between L2 and S1.
正解：A,C,E

質問 8：
Which statement is true about the route shown in the exhibit?

A. The route uses a type-1 route distinguisher.
B. The route target on this route is 1000
C. The VNI for this route is 304.
D. The route is an EVPN type-1 route.
正解：D
