Questions # 221:

Graceful Restart is supported by what IGPs?

Options:

RIPv1 and RIPv2

OSPF

IS-IS

BGP

Questions # 222:

Which of the following best describes how IS-IS routers exchange updates on an Ethernet interface?

Options:

IS-IS routers exchange updates by sending UDP packets to a multicast address.

IS-IS routers exchange updates using IP multicast packets.

IS-IS routers exchange updates using Ethernet multicast packets.

IS-IS routers exchange updates by sending packets to the subnet broadcast address.

Questions # 223:

Which of the following statements regarding distance vectors protocols are true?

(Choose two answers).

Options:

RIPv1, RIPv2, and BGP are distance vector protocols.

OSPF and IS-IS are distance vector protocols.

Routing tables are exchanged between neighbors; however, no routing table is transmitted beyond the immediate neighbor.

Distance vector protocols use the Dijkstra SPF algorithm.

Routers that participate in distance vector routing protocols maintain full knowledge of distant routers and how they interconnect

Questions # 224:

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

Options:

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.

Questions # 225:

When configuring a filter, where should the most explicit entries be placed?

Options:

At the bottom

In the middle

At the top

It does not matter where they are placed.

Questions # 226:

Which of the following best describes the actions after an IS-IS router receives on a broadcast interface, a newer LSP than the one in its database?

Options:

The router sends a copy of the LSP from its database to its neighbor

The router updates its database with the LSP and floods a copy to its other neighbors.

The router updates its database with the LSP, acknowledges the LSP with a PSNP and floods a copy to its other neighbors.

The router updates its database with the LSP and acknowledges it with a PSNP.

Questions # 227:

What are the types of routers in an IS-IS topology? Choose all that apply.

Options:

Level 0

Level 1

Level 2

Level 0/1

Level 1/2

Questions # 228:

Which of the following conditions will prevent an OSPF adjacency from reaching the full state? Choose three answers.

Options:

MTU mismatch

Incorrect subnet mask

System interface not included in OSPF

Area ID not the same

Different metric set on each end of the link

Router ID not defined

Question # 229

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.

Router R3 generates a Type 4 LSA that is flooded to area 0, and router R6 generates a Type 4 LSA that is flooded to area 2.

Questions # 230:

Which of the following statements describe the major features of OSPF? Choose two answers.

Options:

Fast reroute capability

Control traffic prioritization

Route redistribution

Traffic engineering extensions

Cut through forwarding

Questions # 231:

What command allows analysis of the Dijkstra calculation on the Alcatel-Lucent 7750 SR?

Options:

There is no such calculation in IS-IS

Show router isis database

Show router isis dijykstra

Show router isis spf

Questions # 232:

What must be configured on the Alcatel-Lucent 7750 SR for RIP to advertise locally attached links?

Options:

A policy statement within the router identifying what is to be advertised

Access-lists denoting what is to be advertised

Default metrics for each link

A group and neighbor statement for each peer

Questions # 233:

Which of the following statements regarding area border routers in an OSPF network is true?

Options:

The term backbone router has the same definition as the term area border router.

An OSPF network needs at least one area border router to function.

Area border routers connect the backbone area to other areas in an OSPF network.

By definition, an area border router must perform route summarization between areas.

Questions # 234:

How are LSPs acknowledged on IS-IS broadcast links?

Options:

The LSP is acknowledged by sending a PSNP PDU.

The LSP is acknowledged by sending an LSP PDU.

The LSP is acknowledged by sending a Hello PDU.

LSP are not acknowledged on broadcast links. The DIS sends periodic CSNPs to maintain database synchronization

Questions # 235:

What is the metric and maximum routable value for RIP?

Options:

Hop count and 16

Hop count and 15

Link cost and 15

Link cost and 16

Questions # 236:

Exhibit

Question # 236

Given the two configurations shown, identify the two incorrect statements below: (Choose two)

Options:

Both routers will generate OSPF Hello packets.

The system interface is missing in one configuration so OSPF will not operate correctly.

The interface type settings differ, but OSPF will still operate correctly.

Metric values differ, but this does not prevent OSPF operation.

Questions # 237:

Which of the following is an optional parameter when configuring IS-IS protocol on a router?

Options:

Configure IS-IS interfaces

Enable IS-IS

Configure level capabilities

Specify an area address

Questions # 238:

Question # 238

The OSPF packets shown have been exchanged between two neighbors. What state is the OSPF adjacency in?

Options:

The adjacency state is two way because both routers have received a database description packet.

The adjacency is in the exchange state. The next step is to exchange link state request and link state update packets.

The adjacency is in the ex start state. The routers have exchanged database description packets, but still have to negotiate the starting sequence number.

The adjacency state is full. The routers are exchanging database description packets to notify each other that all link state advertisements have been received.

Questions # 239:

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

Options:

The router must receive an acknowledgment

The router must receive a Hello

The router must receive a new sequence number

The router must receive a Link State Packet

Questions # 240:

A router is configured with the command "configure router ecmp 4". There are two best paths to a given destination with an equal cost in the IGP. Which of the following best describes the handling of traffic to this destination?

Options:

The router installs two routes for the destination with two different next hops. A hashing algorithm is used to distribute traffic over the two paths.

The router installs two routes for the destination with two different next hops. Traffic is evenly distributed over the two paths.

The router installs four routes for the destination with four different next hops. A hashing algorithm is used to distribute traffic over the four paths.

The router installs four routes for the destination with four different next hops. Traffic is evenly distributed over the four paths.

The router installs one route for the destination. Traffic is evenly distributed over the two paths.
