   Two Dell PowerSwitch routers are forming an OSPF adjacency over a point-to-point link. The routers have exchanged Hello packets and reached the 2-Way state. What is the next step in the database synchronization process?

   • AThe routers run the SPF algorithm to compute routes before exchanging databases.
   • BThe routers elect a designated router and backup designated router.
   • CThe routers immediately flood all LSAs to each other without any negotiation.
   • DThe routers exchange Database Description (DBD) packets to summarize their link-state databases.

   A Dell PowerSwitch router is connected to an OSPF network via a broadcast interface. The router has just been powered on and OSPF is enabled. What is the first state the router enters in the OSPF neighbor state machine?

   • ADown state
   • B2-Way state
   • CInit state
   • DExStart state

   A network administrator is comparing OSPF to a distance-vector protocol like RIP for a campus network. The administrator notes that OSPF converges faster and is less prone to loops. What is the primary reason for this advantage?

   • AOSPF uses a hold-down timer to prevent routes from changing during convergence.
   • BOSPF sends periodic full routing table updates to all neighbors.
   • COSPF routers maintain a complete map of the network and calculate routes independently using the SPF algorithm.
   • DOSPF uses split horizon to prevent routing loops.

   In a single-area OSPF network, what is the role of an internal router?

   • AIt connects different OSPF areas.
   • BIt is elected to represent other routers on a multi-access segment.
   • CIt has all its interfaces in the same OSPF area and runs OSPF normally.
   • DIt connects OSPF to other routing protocols.
