CCNA Discovery 3 Module 6 Exam Answers Version 4.0
1. • HQ is a DROTHER.
2. • A DR is not elected.
• OSPF neighbor routers are statically defined.
3. • The default-information originate command is applied on R1.
4. • neighbor adjacencies
5. • R3 to R2 to R1
6. • router ospf 1
network 192.168.10.64 0.0.0.63 area 0
network 192.168.10.192 0.0.0.3 area 0
7. • network 10.8.0.0 0.3.255.255 area 0
8. • The router with the highest OSPF priority setting wins the election for DR.
9. • Router2(config-router)# network 172.16.32.0 0.0.15.255 area 0
10.• All routers in the same area have identical link-state databases when converged.
• Calculating the shortest path for each destination is accomplished with the SPF algorithm.
11. • The DR and BDR do not change until the next election.
12. • Elections are required in broadcast multiaccess networks.
• Elections are sometimes required in NBMA networks.
13. • The timer intervals on the routers do not match.
14. • It is the OSPF cost metric.
15. • provides a stable OSPF router ID on router B
16. • The router views 10.16.1.64/30 and 10.16.1.64/27 as two different networks.
17. • Distance vector protocols take existing routes from their neighbors and add to them. Link-state protocols independently calculate full routes.
18. • 192.168.0.0/24 through 192.168.15.0/24
19. • 224.0.0.5
20. • R2 will be DR and R3 will be BDR.
21. • isolation of network instability
22. • Routers have direct knowledge of all links in the network and how they are connected.
• After the initial LSA flooding, routers generally require less bandwidth to communicate changes in a topology.
23. • Each router has a link-state database containing the same status information.
24.• The OSPF routing configuration on RTRC has a missing or incorrect network statement.
