Free Practice Questions for Nokia 4A0-113 Exam

Question 1

In an OSPF environment, what must a router receive after it sends out an update?

AThe router must receive an acknowledgment

BThe router must receive a Hello

CThe router must receive a new sequence number

DThe router must receive a Link State Packet

Correct Answer: A. The router must receive an acknowledgment

Question 2

Which of the following statements regarding OSPF routing updates on a multi-access network segment is true?

AIn multi-access networks, a DR and BDR are elected only if there are more than two routers connected to the network segment.

BIn multi-access networks, a DR and BDR are elected only if the subnet masks on the router interfaces are less than /30

CIn multi-access networks, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.

DIn multi-access networks, a DR and BDR are elected. The DR sends link-state advertisements describing the network.

Correct Answer: D. In multi-access networks, a DR and BDR are elected. The DR sends link-state advertisements describing the network.

Question 3

Which of the following statements best describes the function of an OSPF Type 4 LSA?

AA Type 4 LSA is originated by an ABR to describe a route to an ASBR to routers outside the area.

BA Type 4 LSA is originated by an ASBR to describe a route to itself to routers outside the area.

CA 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.

DA 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.

Correct Answer: A. A Type 4 LSA is originated by an ABR to describe a route to an ASBR to routers outside the area.

Question 4

A static route is created using the command "static-route 0.0.0.0/0 next-hop 3.3.3.1". What command could be used to test the static route on an Nokia 7750 SR?

APing static 3.3.3.1

BPing static 0.0.0.0/0

CPing 3.3.3.1

DPing 0.0.0.0

Correct Answer: C. Ping 3.3.3.1

Question 5

What is the protocol number for OSPF in the IP header?

AOSPF uses TCP, so the protocol number is 6.

BOSPF uses UDP, so the protocol number is 17.

COSPF does not use IP.

DOSPF has its own protocol number of 89.

Correct Answer: D. OSPF has its own protocol number of 89.

Question 6

What is the metric and maximum routable value for RIP?

AHop count and 16

BHop count and 15

CLink cost and 15

DLink cost and 16

Correct Answer: B. Hop count and 15

Question 7

Which of the following commands can be used to display the number of SPF computations that have been performed on a router?

Ashow router ospf area

Bshow router ospf neighbor

Cshow router ospf interface

Dshow router ospf status

Correct Answer: A. show router ospf area

Question 8

What is the default preference value for a static route in the Nokia 7750 SR router?

A0

B5

C10

D15

Correct Answer: B. 5

Question 9

When redistributing OSPF into RIP V2 what must be taken into consideration for the redistribution to take place?

AThe metric must be set accordingly for RIP

BThe subnet mask must be removed from the OSPF route

CYou must divide the cost of the OSPF route by three

DThe router must be configured as an ASBR

Correct Answer: A. The metric must be set accordingly for RIP

Question 10

In an IP datagram, which of the following fields identifies the receiving application?

AThe protocol field of the transport layer header.

BThe port field of the transport layer header.

CThe protocol field of the network layer header.

DThe port field of the network layer address.

Correct Answer: B. The port field of the transport layer header.
