   A service provider has two routers connected over an Ethernet segment. The routers are configured with different OSPF hello intervals. Router A has a hello interval of 10 seconds, and Router B has a hello interval of 30 seconds. What is the most likely result of this configuration?

   • CThe routers will form an adjacency, but the dead interval will be set to the higher value.
   • DThe routers will not form an adjacency because the hello intervals do not match.
