Answer: C 


Q8. A Service Provider connects to a client site that has two CEs. These CEs have a backdoor link for backup. OSPF is used as the routing protocol in this environment. You want to ensure that client traffic prefers the service provider connections for routing instead of the secondary connection. Which option describes the default behavior and the action that accomplishes your goal? 

A. The routes to the Service Provider are not preferred, due to the increased OSPF cost through the service provider network. Ensure that the cost on the links to the service provider are lower than the secondary connection. 

B. The routes to the Service Provider are seen as external type 1 in the OSPF database. Configure a domain ID that is the same across all PEs, to ensure that customers see routes as intra-area. 

C. The routes to the Service Provider are seen as inter-area OSPF routes through the network. Configure a sham link to create a new intra-area path across the service provider network between the PE routers that service the client. 

D. The routes to the Service Provider are seen as equal and cause nondeterministic traffic patterns. Ensure that the secondary connection has a higher cost than the links to the service provider. 

Answer: C
