Questions # 201:

Which of the following LSA types stay within an OSPF area, and are not flooded outside of the area? Choose two answers.

Options:

Router LSA

Network LSA

C Summary network LSA

Summary router LSA

Type 5 (AS external) LSAs

Questions # 202:

An OSPF router receives an update in which the sequence number, age, and checksum are the same as the entry already in the topological database. What action is taken by the router?

Options:

The link state information is not populated in the database but is forwarded to all neighbors

The link state information already in the database is overwritten and the age is reset

The link state information is not populated in the database and an acknowledgement is sent

The link state information is regarded as old and nothing is done.

Questions # 203:

What are the similarities between OSPF and IS-IS? Choose two.

Options:

Metric is cost based

Slow convergence

Automatic summarization

Support CIDR

Questions # 204:

What acts as the tie breaker on an Alcatel-Lucent 7750 SR if the priorities are the same when IS-IS is electing a DIS?

Options:

The system ID

The loopback address

The sequence number of the hello packet

The device that first initiated communication becomes the DIS

Questions # 205:

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

Options:

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.

Questions # 206:

What command is used on the Alcatel-Lucent 7750 SR to define the default action to be taken if a packet does not match any entry in an IP filter?

Options:

config>filter# default-action XXX

config>filter>ip-filter# default-action XXX

config>filter# default-mode XXX

config>filter>ip-filter# default-mode XXX

Question # 208

In the topology shown, router R1 is an ASBR configured to export external routes to OSPF. Assuming that there are no stub networks, which of the following statements regarding type 4 LSA generation is true?

Options:

Router R1 generates a type 4 LSA that is flooded to areas 0, 1, and 2.

Router R3 generates a type 4 LSA that is flooded to areas 0, 1, and 2.

Router R3 generates a type 4 LSA that is flooded to areas 0 and 2.

Questions # 210:

Identify two attributes of Distance Vector Protocols: (Choose two)

Options:

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.

Options:

The router with router ID 10.10.10.5 is an ASBR.

The router with router ID 10.10.10.3 is an ASBR.

The router with router ID 10.10.10.5 originated the AS summary LSA in its own area.

The router with router ID 10.10.10.4 is in the same area as the router with router ID 10.10.10.5.

Questions # 213:

Which one of the commands below will create a static route to network 2.3.4.0/24 on the AlcatelLucent 7750 SR router?

Options:

Options:

Neighbor, adjacency, route table

Neighbor, topology, forwarding

Topology, routing, forwarding

There are only two databases: adjacency and topology

Questions # 215:

What command will show the OSPF neighbors, and their status on the Alcatel-Lucent 7750 SR?

Options:

Show ospf neighbors

Show router ospf neighbors

Options:

Questions # 217:

If two routers running IS-IS protocols are exchanging Hello packets with different authentication types, which of the following statements regarding the adjacency state established between them is true?

Options:

Different authentication types are not possible because IS-IS only supports password authentication.

An adjacency will not be formed

The two routers negotiate the authentication type and then reach the up state.

Only an L2 adjacency will form, as long as both routers are L2 capable.
