1. What two actions will the EIGRP DUAL FSM take if a link to a network goes down? (Choose two.)

put the route into passive mode

query neighbors for a new route

search routing table for a feasible successor

run the SPF algorithm to find a new successor

search topology table for a feasible successor

2.

Host 192.168.1.66 in the network illustrated is unable to ping host 192.168.1.130. How must EIGRP be configured to enable connectivity between the two hosts? (Choose two.)

R1(config-router)# network 192.168.1.128

R1(config-router)# auto-summary

R1(config-router)# no auto-summary

R2(config-router)# no auto-summary

R2(config-router)# auto-summary

R2(config-router)# network 192.168.1.64

1. In the graphic, Host A has reached 50% completion in sending a 1 KB Ethernet frame to Host D when Host B wishes to transmit its own frame to Host C. What must Host B do?

Host B can transmit immediately since it is connected on its own cable segment.

Host B must wait to receive a CSMA transmission from the hub, to signal its turn.

Host B must send a request signal to Host A by transmitting an interframe gap.

Host B must wait until it is certain that Host A has completed sending its frame.

2. Ethernet operates at which layers of the OSI model? (Choose two.)

Network layer

Transport layer

Physical layer

Application layer

Session layer

Data-link layer
