The service label is swapped at each hop in the transport network.

A.

The router with router ID 10.10.10.5 is an ASBR.

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

A.

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.

B.

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.

C.

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

D.

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

E.

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.

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.

A.

Not So Stubby Area

B.

Stub Area

C.

Backbone Area

D.

Standard Area

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?

A.

The system ID

B.

The loopback address

C.

The sequence number of the hello packet

D.

The device that first initiated communication becomes the DIS

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

A.

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

B.

IS-IS routers exchange updates using IP multicast packets.

C.

IS-IS routers exchange updates using Ethernet multicast packets.

D.

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

B.

configure router static-route 139.120.121.0/24 next-hop 138.120.199.1

D.

configure router static-route 139.120.121.0/24 next-hop 139.120.121.2
