  B. Configure the TEP pool of the new pod to be routable across the IPN
  C. Configure MP-BGP on IPN routers that face the Cisco ACI spines
  D. Increase interface MTU for all IPN routers to support VXLAN traffic
  E. Connect all spines to the IPN
  B. Configure the TEP pool of the new pod to be routable across the IPN

• Question 7:

  Refer to the exhibit.

  

  Server S1 is connected to Cisco ACI using two NIC interfaces. NIC1 is an active interface and NIC2 is a standby interface. NIC2 uses its MAC address to send traffic to the Cisco ACI fabric when NIC1 is offline. The requirement is to update the IP address to use the MAC address of NIC2. Which action accomplishes this goal?

  A. Clear remote MAC entries.
  B. Set L2 Unknown Unicat to Proxy.
  C. Activate IP Data Plane Learning.
  D. Enable GARP EP Move Detection
  D. Enable GARP EP Move Detection

• Question 8:

  What is the purpose of enabling ARP flooding when VMs are migrated from a pre-existing network to Cisco ACI and their gateways remain configured in the legacy setup?

  A. to avoid endpoint flapping between the legacy network and the ACI fabric
  B. to prevent VMs from communicating with physical servers within the ACI fabric
  C. to allow communication between VMs and silent hosts
  D. to allow VMs to communicate with devices outside of their subnet
  A. to avoid endpoint flapping between the legacy network and the ACI fabric

• Question 9:

  Which PIM version must be configured in the Inter-Pod Network to allow broadcast, unknown unicast, and multicast flooding between Cisco ACI pods?

  A. Bidirectional PIM
  B. PIM dense mode
  C. PIM sparse mode
  D. Source Specific Multicast
  A. Bidirectional PIM

• Question 10:

  What is a design implication for Cisco ACI using an application-centric approach?

  A. Multiple VLANs and/or multiple EPGs are under one bridge domain
  B. VLAN numbers are in the names of the bridge domain and EPG objects
  C. One EPG is mapped to multiple bridge domains
  D. One VLAN equals one EPG equals one bridge domain
  A. Multiple VLANs and/or multiple EPGs are under one bridge domain
