- Updating and maintaining routing tables
4. Which two statements are true regarding classless routing protocols? (Choose two.)
- Classless routing protocols reduce the amount of address space available in an organization.
- Classless routing protocols send complete routing table updates to all neighbors.
- Classless routing protocols support VLSM and CIDR.

5. In the context of routing protocols, what is convergence time?
- A measure of protocol configuration complexity
- The amount of time a network administrator needs to configure a routing protocol in a small to medium-sized network
- The amount of time for the routing tables to achieve a consistent state after a topology change
- The capability to transport data, video, and voice over the same media
6. Which two events will trigger the sending of a link-state packet by a link-state routing protocol? (Choose two.)
- A change in the topology
- A link to a neighbor router becoming congested
- The initial startup of the routing protocol process
- The requirement to periodically flood link-state packets to all neighbors
- The router update timer expiring
7. Which two requirements are necessary before a router configured with a linkstate routing protocol can build and send its link-state packets? (Choose two.)
- The router has built its link-state database.
- The router has constructed an SPF tree.
- The router has determined the costs associated with its active links.
- The router has established its adjacencies.
- The routing table has been refreshed.
8. Which two statements describe the OSPF routing protocol? (Choose two.)
- It automatically summarizes networks at the classful boundaries.
- It calculates its metric by using bandwidth.
- It has an administrative distance of 120.
- It uses Dijkstra’s algorithm to build the SPF tree.
- It is used primarily as an EGP.
9. How do EIGRP routers establish and maintain neighbor relationships?
- They compare known routes to information received in updates.
- They dynamically learn new routes from neighbors.
- They exchange hello packets with neighboring routers.
- They exchange neighbor tables with directly attached routers.
- They exchange routing tables with directly attached routers.
