• Question 103:

  Which device replicates Broadcast, Unicast, and Multicast (BUM) frames to all remote sites in a Cisco ACI Multi-Site with multiple stretched bridge domains?

  A. remote spine node that translates the VNID to the locally significant value
  B. receiving leaf that learns the location for the sourced BUM traffic
  C. source leaf that floods the traffic to the specific multicast group or GlPo
  D. local spine that is elected the designated forwarder for each bridge domain
  D. local spine that is elected the designated forwarder for each bridge domain

• Question 104:

  A packet is routed between two endpoints on different Cisco ACI leaf switches. Which VXLAN VNID is applied to the packet?

  A. VRF
  B. EPG
  C. BD
  D. FD
  A. VRF

• Question 105:

  As part of a newly deployed ACI fabric, a pair of border leaf switches have been deployed to provide shared services for all tenants. The configured L3Out runs OSPF as the routing protocol. The requirement is to advertise the routes from the border leaf switches to the compute leaf switches. Which configuration must be implemented to meet these requirements?

  A. Configure a BGP route reflector policy for the Cisco ACI pod
  B. Define the shared L3Out in the common tenant
  C. Enable Import Route Control Enforcement in the L3Out policy
  D. Define the consumer subnet under the consumer EPG
  A. Configure a BGP route reflector policy for the Cisco ACI pod
