質問 1：
Referring to the exhibit, each node in the IP fabric is peering to its directly attached neighbor using EBGP. Each node is peering using physical interface IP addresses. Leaf 2 and Leaf 3 are advertising the 10.1.1/24 network into EBGP. Spine 2 must be configured so that it can load-share traffic destined to the 10 1.1/24 network over both next-hop A and next-hop B.

Which two actions must be performed to accomplish this task? (Choose two.)
A. Use multihop
B. Use advertise inactive
C. Use multipath multipath-As
D. Use a load-balancing policy applied to the forward table
正解：C,D

質問 2：
What is the purpose of the command shown in the exhibit?

A. To stop the transmission of transit multicast traffic when there are no interested receives attached to a remote VTEP
B. To stop the reception of transit multicast traffic when there are no interested receives attached to the local VTEP
C. To disallow IGMP request for the group 239.0.01 from host attached to the local VTEP
D. To disable the group2390.0.1 across the entire VXLAN.
正解：A

質問 3：
Your colleague has begun working on the base configuration for an active-active multihomed EVPN connection shown in the exhibit.

A. The underlay should support the PIM protocol
B. The underlay should advertise the host connected interlaces on all leaf device
C. Each device in the underlay should advertise its loopback address
D. The underlay should be configured with a separate VRF tor each potential tenant
正解：C
