- Q1What is a possible reason for creating an OSPF network with multiple areas?to simplify configurationto ensure that an area is used to connect the network to the Internetto reduce SPF calculationsto provide areas in the network for routers that are not running OSPF30s
- Q2What is a possible reason for creating an OSPF network with multiple areas?to simplify configurationto reduce use of memory and processor resourcesto provide areas in the network for routers that are not running OSPFto ensure that an area is used to connect the network to the Internet30s
- Q3What is used to facilitate hierarchical routing in OSPF?frequent SPF calculationsthe election of designated routersthe use of multiple areasautosummarization30s
- Q4Which statement correctly describes OSPF type 3 LSAs?Type 3 LSAs are known as router link entries.Type 3 LSAs are generated without requiring a full SPF calculation.Type 3 LSAs are used for routes to networks outside the OSPF autonomous system.Type 3 LSAs are known as autonomous system external LSA entries.30s
- Q5Which statement correctly describes OSPF type 3 LSAs?Type 3 LSAs are used to update routes between OSPF areas.Type 3 LSAs are known as autonomous system external LSA entries.Type 3 LSAs are used for routes to networks outside the OSPF autonomous system.Type 3 LSAs are known as router link entries.30s
- Q6Which characteristic describes both ABRs and ASBRs that are implemented in a multiarea OSPF network?They usually have many local networks attached.They both run multiple routing protocols simultaneously.They are required to reload frequently and quickly in order to update the LSDB.They are required to perform any summarization or redistribution tasks.30s
- Q7What type of OSPF LSA is originated by ASBR routers to advertise external routes?type 2type 5type 3type 130s
- Q8What OSPF LSA type is used to inform routers of the router ID of the DR in each multiaccess network in an OSPF area?type 3type 2type 4type 130s
- Q9Which statement is correct?The routing table contains routes from multiple areas.The entry for 172.16.200.1 represents a loopback interface.The routing table contains two intra-area routes.To reach network 172.16.2.0, traffic will travel through the GigabitEthernet0/0 interface.120s
- Q10Which statement is correct?The routing table contains two intra-area routes.The entry for 172.16.200.1 represents a loopback interface.To reach network 192.168.1.0, traffic will exit via the Serial0/0/0 interface.To reach network 172.16.2.0, traffic will travel through the GigabitEthernet0/0 interface.120s
- Q11What routing table descriptor is used to identify OSPF summary networks that originate from an ABR?O E2O E1OO IA30s
- Q12A network administrator is verifying a multi-area OSPF configuration by checking the routing table on a router in area 1. The administrator notices a route to a network that is connected to a router in area 2. Which code appears in front of this route in the routing table within area 1?O IACOO E245s
- Q13What can be concluded about network 192.168.4.0 in the R2 routing table?The network can be reached through the GigabitEthernet0/0 interface.The network was learned from a router within the same area as R2.The network was learned through summary LSAs from an ABR.This network should be used to forward traffic toward external networks.120s
- Q14Which step in the design and implementation of a multiarea OSPF network is considered a planning step?Verify OSPF.Define the OSPF parameters.Configure OSPF.Troubleshoot the configurations.45s
- Q15Which step in the design and implementation of a multiarea OSPF network is considered a planning step?Troubleshoot the configurations.Gather the required parameters.Verify OSPF.Configure OSPF.45s
