1 Examine the following routing table entry displayed by the show ip route
on a router running RIP and EIGRP.
D EX 172.25.0.0/16 [170/2221056] via 172.20.15.0, 00:40:41, Serial0
Which statement best describes this routing table entry?
route was imported from outside the EIGRP AS
route was redistributed into OSPF from RIP
route was redistributed into IGRP from RIP
route was imported into RIP from EIGRP EX
Ans.route was imported into RIP from EIGRP EX.
2 Which command will assign an OSPF priority?
RouterA# ip ospf priority 10
RouterA(config-if)# ip ospf priority 10
RouterA(config)# ip ospf priority 10
RouterA(config-router)# ip ospf priority 10
Ans.RouterA(config-if)# ip ospf priority 10.
3 During periods of congestion, what routing process schedules packets for
delivery to ensure that mission-critical and delay sensitive traffic is
processed first?
queuing
load balancing
packet sequencing
route optimization
compression
Ans.route optimization
4 How does RIPv2 recover from a link failure?
The least cost alternate route is selected from the routing table.
An alternate route is determined from subsequent scheduled routing updates.
A link failure broadcast is issued to neighboring routers, who respond with
alternate paths.
A route query is sent to neighboring RIPv2 routers.
Ans.An alternate route is determined from subsequent scheduled routing updates.
5 Which mechanism is used by Cisco's implementation of RIP and IGRP to
decrease the convergence time when a link fails?
triggered updates
time-driven timers
event-driven timers
topology updates
Ans.triggered updates.
