Nokia OSPF Routing Protocol Exam 4A0-113 Free Questions https://www.passquestion.com/ 4A0-113 .html An interface is configured on a router for OSPF but the command "show router ospf neighbor" does not show any neighbors. Which of the following is NOT a possible cause? A.An OSPF database description packet has not been received from the neighbor. B.The interface facing the neighbor is down. C.The interface is included in a different area than the neighbor router. D.The router has not received a valid OSPF Hello packet from its neighbor. Answer : A Question 1 Which of the following statements best describes the function of an OSPF Type 4 LSA? A.A Type 4 LSA is originated by an ABR to describe a route to an ASBR to routers outside the area. B.A Type 4 LSA is originated by an ASBR to describe a route to itself to routers outside the area. C.A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the backbone area to provide routing information. D.A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the stub area to provide routing information. Answer : A Question 2 Which of the following statements concerning OSPFv3 is false? A.MD5 Authentication is not supported. B.Router LSAs do not carry IPv6 prefix information C.NSSA is not supported in OSPFv3. D.OSPFv3 uses a 32-bit router ID. Answer : C Question 3 A router receives an OSPF database description packet from a neighbor that references an LSA, which is already in the router's LSDB. The sequence number in the DBD packet is lower than the sequence number of the LSA in the LSDB. What action does the router take? A.The router sends a link-state update to its neighbor. B.The router sends a link-state acknowledgement to its neighbor. C.The router updates the information in its LSDB with the information received from its neighbor. D.The router sends a link-state request to its neighbor. E.The router takes no action. Answer : A Question 4 Which LSA type is not found in point-to-point only OSPF networks? A.Type 1 Router LSA B.Type 2 Network LS A C.Type 3 Summary LSA D.Type 5 External LSA Answer : B Question 5 What is the default priority value used for electing the DR on an Nokia 7750 SR running OSPF on an Ethernet? A.Priority of 0 B.Priority of 1 C.Priority of 64 D.Priority of 255 Answer: B Question 6 Which of the following statements regarding the election of the designated router (DR) by OSPF routers are true? (Choose two) A.The router with the lowest priority is the DR. B.The router with the highest priority is the DR. C.If priorities are the same, the DR is chosen based on the lowest RID. D.If priorities are the same, the DR is chosen based on the highest RID. Answer: B, D Question 7 What are the types of networks supported on an Nokia 7750 SR for OSPF? (Choose 2) A.Broadcast B.Non-Broadcast Multi-Access C.Point-to-Point D.Point-to-Multipoint Answer: A, C Question 8 What are the ways the RID can be created on an Nokia 7750 SR router? (Choose three) A.From the last 32 bits of the chassis MAC address B.From the first 32 bits of the chassis MAC address C.The loopback IP address D.By using the command 'config router ospf rid X.X.X.X' E.From the system IP address F.From the highest interface IP address Answer: A, D, E Question 9 The route table on router R2 shows the system address of router R5 but it does not show any of the interfaces from the non-OSPF area. What may be causing this? A.'asbr' is missing from router R1's configuration. B.Router R1 needs to have an export policy added to it. C.Router R5 does not have an export policy for these prefixes. D.Router R1 needs to have an import policy added to it. Answer : C Question 10
