  B. Procure additional bandwidth.
  C. Use dynamic routing toward the WAN.
  D. Add an additional link to the WAN.
  C. Use dynamic routing toward the WAN.

  A. Enable route-filtering on OSPF backbone routers for spoke traffic
  B. Advertise low AD value for transit traffic on hub sites.
  C. OSPF backbone area advertises summarized routes to hub.
  D. Redistribute EIGRP 200 and 300 with low cost into BGP
  C. OSPF backbone area advertises summarized routes to hub.
