4A0-101 Question 71

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

Options:

Questions 72

When an OSPF adjacency is stuck in the "ExchStart" state, what is the most likely cause?

Options:

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

Questions 73

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 74

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 75

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

4A0-101 Question 77

What triggers convergence of the routing protocol when the link between switch 1 and switch 2 goes down?

Options:

Convergence is triggered when the adjacency between routers R1 and R2 drops as a result of Hello timeouts. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

Convergence is triggered when the physical interfaces between routers R1 and R2 go down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

Convergence will not be triggered because switches cannot run routing protocols between them.

Convergence is triggered when the switches notify the routers about the link state information. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged

Convergence is triggered when an LSA is sent from router R1 to router R2 to indicate that the link is down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

Questions 78

Which of the following features are supported by IS-IS? Choose three answers.

Options:

PDU authentication.

The ability to customize the link cost metric.

Use of Bellman-Ford routing algorithm.

Classless routing.

Updates sent as layer 3 multicast.

Questions 79

Which of the following statements regarding IS-IS Hello packets are true? Choose two answers.

Options:

Different types of Hello packets are exchanged on point-to-point networks than on broadcast networks.

L1/L2 Hello packets are exchanged on broadcast links.

Different L1 and L2 Hello packets are exchanged on broadcast links.

By default, Hello packets are sent every 5 seconds, and the timeout to declare a neighbor down is 15 seconds.

4A0-101 Question 80

Router R2 advertises the network 192.168.3.0/24 to router R1 via OSPF. A route policy has been constructed to discard the route on router R1; however, it is not working. What is the problem?

Options:

The prefix list reject should be "192.168.3.0/16 exact".

Router R1 should be configured as an OSPF "asbr".

The policy "reject" should be set for import rather than export.

The policy was likely not "committed" after creation.

This is not possible because OSPF cannot use import policies.
