Question 21.  Which of the following describe the process identifier that is used to run OSPF on a router?
1. It is locally significant.
2. It is globally significant.
3. It is needed to identify a unique instance of an OSPF database.
4. It is an optional parameter required only if multiple OSPF processes are running on the router.

Question 22.  Your company is running IGRP using an AS of 10. You want to configure EIGRP on the network but want to migrate slowly to EIGRP and don't want to configure redistribution. What command would allow you to migrate over time to EIGRP without configuring redistribution?

Question 23.  What is the administrative distance of OSPF?

Question 24.  A network administrator needs to configure a router with a distance-vector protocol that allows classless routing. Which of the following satisfies those requirements?

Question 25.  Which command will display all the EIGRP feasible successor routes known to a router?

Question 26.  Where are EIGRP successor routes stored?

Question 27.  Which EIGRP information is held in RAM and maintained through the use of Hello and update packets?
1. Neighbor table
2. STP table
3. Topology table
4. DUAL table

Question 28.  Which is true regarding EIGRP successor routes?
1. A successor route is used by EIGRP to forward traffic to a destination.
2. Successor routes are saved in the topology table to be used if the primary route fails.
3. Successor routes are flagged as "active" in the routing table.
4. A successor route may be backed up by a feasible successor route.
5. Successor routes are stored in the neighbor table following the discovery process.

Question 29. . What are reasons for creating OSPF in a hierarchical design?
1. To decrease routing overhead
2. To speed up convergence
3. To confine network instability to single areas of the network
4. To make configuring OSPF easier

Question 30. . If routers in a single area are configured with the same priority value, what value does a router use for the OSPF Router ID in the absence of a loopback interface?
