NEW QUESTION 46
Which type of OSPF LSA has the following characteristics: It is flooded only within the area it originates from and can be originated by any OSPF router within the area (including non-DR routers).

Type 1 Router LSA

Type 2 Network LSA

Type 3 Summary LSA

Type 4 ASBR LSA

NEW QUESTION 47
When an OSPF adjacency is stuck in the “ExchStart” state, what is the most likely cause?

The MTU does not match on both interfaces

OSPF is not enabled on one of the routers

The Router ID is the same on both routers

A OSPF Hello has not been received from the neighbor

NEW QUESTION 48
If OSPF is used in a multi-area OSPF network, which of the following statements regarding route summarization is true?

Manual route summarization can only be done on autonomous system border routers.

Manual route summarization must be done on all the backbone routers to be effective. Manual route summarization is optional on the routers in non-backbone areas.

Manual route summarization is done on the ABRs. By default, automatic summarization is done; however, it may not be optimal for all networks.

Manual route summarization is done on the ABRs. By default, no route summarization is done and all routes are advertised to all areas.

NEW QUESTION 49
In an OSPF Hello packet what fields must match all neighbor routers on the segment? (Choose 3)

Area ID

Hello and Dead Intervals

Stub flag

DR and BDR addresses

The list of neighbors

NEW QUESTION 50
Identify two attributes of Distance Vector Protocols: (Choose two)

Use split horizon by default.

Send information about directly connected links to neighbors at periodic intervals.

Use holddown timers when topologies change to allow for convergence.

Maintain multiple databases: neighbor, topology and routing.

NEW QUESTION 51
Click the exhibit button.

If router R2 redistributes the IS-IS route to 192.168.3.0/24 into OSPF, router R3 will receive two routes to 192.168.3.0/24. What will be the preference of these two routes? Assume that all IS-IS routers are L1/L2 capable and are in the same are a. Choose two answers.

The OSPF internal preference

The IS-IS Level 1 internal preference

The IS-IS Level 2 internal preference

The OSPF external preference

The IS-IS Level 2 external preference

The IS-IS Level 1 external preference

NEW QUESTION 52
In an IP datagram, which field identifies the receiving application

The protocol field of the transport layer header

The port field of the transport layer header

The protocol field of the network layer header

The port field of the network layer address

NEW QUESTION 53
An OSPF adjacency is stuck in the exstart state. What is the most likely cause?

The MTU does not match on both interfaces.

OSPF is not enabled on one of the routers.

The router ID is the same on both routers.

An OSPF Hello has not been received from the neighbor.

The interfaces are configured as point-to-point on one side and broadcast on the other.

NEW QUESTION 54
Which of the following commands can be used to display the number of SPF computations that have been performed on a router?

show router ospf area <area-id>

show router ospf neighbor

show router ospf interface

show router ospf status

NEW QUESTION 55
If a Router originates a type 1 router LSA with the E bit set what types of areas can it belong to? Select all that apply.

Not So Stubby Area

Stub Area

Backbone Area

Standard Area

NEW QUESTION 56
Refer to the exhibit.

Assume that OSPFv3 is properly configured on all routers and that R4 advertises its system prefix into Area 0. Which of the following statements best describes how R5 learns R4’s IPv6 system prefix?

With a Router LSA originated by R1

With a Router LSA originated by R5

With a Router LSA originated by R4

With an Inter-Area Prefix LSA originated by R1

With an Inter-Area Prefix LSA originated by R5

With an Inter-Area Prefix LSA originated by R4

NEW QUESTION 57
Click on the exhibit.

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?

‘asbr’ is missing from router R1’s configuration.

Router R1 needs to have an export policy added to it.

Router R5 does not have an export policy for these prefixes.

Router R1 needs to have an import policy added to it.

NEW QUESTION 58
What are the ways the RID can be created on an Nokia 7750 SR router? (Choose three)

From the last 32 bits of the chassis MAC address

From the first 32 bits of the chassis MAC address

The loopback IP address

By using the command “config router ospf rid X.X.X.X”

From the system IP address

From the highest interface IP address

NEW QUESTION 59
Click the exhibit button.

Two neighboring OSPF routers have exchanged the packets shown. What state is the adjacency in?

Full; both routers are exchanging Helios to maintain the adjacency.

The adjacency is down.

The adjacency is in exstart state.

The adjacency is in the exchange state.

NEW QUESTION 60
When are virtual links used in OSPF?

When two areas need to communicate and there is no area 0.

When an area needs to traverse another area to reach area 0.

When two areas are connected to area 0, but there is no direct path between them.

When an area needs to connect directly to another area without using area 0.

NEW QUESTION 61
What type of LSA is used to flood information about prefixes from one OSPF area to other attached areas?

Type 1

Type 3

Type 4

Type 7

NEW QUESTION 62
Which of the following statements apply to link state protocol behavior? Choose three answers.

Routers broadcast the entire route table to all neighbors.

Information about directly connected links is sent to all neighbors.

An adjacency database is maintained by each router.

The sequence number for an update is incremented as it is flooded from router to router.

The topological database is the same for all routers in a single area.

NEW QUESTION 63
What is the default inbound metric for RIP on the Nokia 7750 SR?

Whatever the advertised metric happens to be.

A value of 1.

This must be administratively set as there is no default value.

A value of 15.

NEW QUESTION 64
An operator configures an Nokia 7750 SR with a loopback interface and IPv6 address. The operator then configures a routing policy to redistribute the loopback prefix into OSPFv3. What type of LSA is used to advertise the route to other OSPFv3 routers in the same area?

Router LSA

AS External LSA

Intra-Area Prefix LSA

Inter-Area Prefix LSA

Network LSA

None of the statements are correct.
