Question 8

An engineer configures Cisco ACI Multi-Site and must specify the control plane TEP IP for spines. Which statement describes control plane TEP IP in this situation?

  • A. The unique IP address is defined on each spine node that belongs to a fabric and is used to establish MP-BGP EVPN and VPNv4 adjacencies with the spine nodes in remote sites.
  • B. The unique IP address is defined on each spine node that belongs to a fabric and is used to establish VXLAN adjacencies with the spine nodes in remote sites.
  • C. The common anycast address is shared by all the spine nodes in the same site and is used to perform headend replication for BUM traffic.
  • D. The common anycast address is shared by all the spine nodes at the same site and is used to source and receive unicast VXLAN data plane traffic.

Question 10

An engineer is implementing the Cisco ACI fabric but is experiencing loops detected from endpoints. When the issue was investigated, it was discovered that the packets are received with the same source IP address but from different leaf switch ports. The engineer must prevent the issue from happening in the future and make sure that the port is brought back up if it was disabled due to the loop discovered. Which set of actions must be taken to meet these requirements?

  • A. Enable the enforce endpoint check and set the Rouge EP detection interval
  • B. Enable the rogue endpoint and set the Error Disabled Recovery Policy
  • C. Enable the remote endpoint limit and set the Interface override
  • D. Enable reverse path forwarding and set the Hold Interval
