A router is participating in an OSPFv2 domain. What will always happen if the dead interval expires before the router receives a hello packet from an adjacent DROTHER OSPF router?
OSPF will remove that neighbor from the router link-state database
Which parameter is commonly used to identify a wireless network name when a home wireless AP is being configured?
SSID
What are some parameters that should match in order for pair of routers to form an adjacency when running OSPFv2?

What does the SPF algorithm consider to be the best path to a network?
The path that includes the fastest cumulative bandwidth links
What is one of the router ID in OSPF routing?
The router ID can be used to break a tie in the election process
What happens immediately after two OSPF routers have exchanged hello packets and have formed a neighbor adjacency?
They exchange abbreviated lists of their LSDBs.
