CCNA 2 Routing and Switching Essentials v5 Chapter 7: Routing Dynamically – Check Your Understanding Questions Answers
1. What is the difference between interior and exterior routing protocols?
- Exterior routing protocols are used only by large ISPs. Interior routing protocols are used by small ISPs.
- Interior routing protocols are used to route on the Internet. Exterior routing protocols are used inside organizations.
- Exterior routing protocols are used to administer a single autonomous system. Interior routing protocols are used to administer several domains.
- Interior routing protocols are used to communicate within a single autonomous system. Exterior routing protocols are used to communicate between multiple autonomous systems.
2. Which factor directly affects the time to convergence?
- Data link layer protocol used
- Number of hosts
- Size of the network
- Type of applications used
3. Which classless routing protocol supports VLSM and CIDR, supports manual route summarization, and uses the multicast address 184.108.40.206?
4. What are two characteristics of link-state protocols compared to distance vector protocols? (Choose two.)
- They require a lot of hardware resources.
- They know of the network topology from the perspective of their neighbors.
- They compute their own knowledge of the network topology.
- They use hop counts to compute the network topology.
- They flood the routing table periodically.
5. Which classless routing protocol supports VLSM and CIDR, bounded and triggered updates, and uses the multicast address of 220.127.116.11?
6. Which algorithm is used by the OSPF routing process to construct the SPF tree on a router?
- DUAL algorithm
- Bellman-Ford algorithm
- Dijkstra’s algorithm
- Path vector protocol
7. What is an advantage of OSPF compared to RIP?
- Fast convergence
- Less complexity
- Less CPU processing
- Low memory requirements
8. A network administrator has examined the routing table of a router and noted that the entry for the destination network 172.16.4.0/24 begins with the letter D. What does this letter signify?
- The route to network 172.16.4.0/24 is directly connected.
- The route source was learned dynamically.
- That is the direct route for packets to that network.
- The route to this network is configured statically on the router.
9. What is the purpose of classifying Cisco IP routing table entries as ultimate route, level 1 route, level 1 parent route, and level 2 child routes?
- To enable the implementation of dynamic routing protocols
- To explain the operation of the routing table as a flat database
- To enable Cisco routers to implement both IPv4 and IPv6 routing
- To explain the operation of the hierarchical structure of the routing table
10. What are two functions of dynamic routing protocols? (Choose two.)
- to maintain routing tables
- to assure low router overhead
- to avoid exposing network information
- to discover the network
- to choose the path that is specified by the administrator
