Chapter 8

Which set of commands will configure dialer watch on RTRA to watch for the Ethernet networks on RTR D?


RTRA(config-if)#dialer watch-list 1 ip 172.10.10.0
RTRA(config-if)#dialer watch-list 1 ip 172.10.20.0

RTRA(config)#dialer watch-group 2 ip 172.10.10.0 255.255.255.0
RTRA(config)#dialer watch-group 2 ip 172.10.20.0 255.255.255.0

RTRA(config-if)#dialer watch-group 1 ip 172.10.10.0
RTRA(config-if)#dialer watch-group 1 ip 172.10.20.0

RTRA(config)#dialer watch-list 2 ip 172.10.10.0 255.255.255.0 X
RTRA(config)#dialer watch-list 2 ip 172.10.20.0 255.255.255.0 X

Which routing protocol uses the variance command to provide unequal-cost load balancing?

BGP
EIGRP X
OSPF
RIPv2
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
When OSPF is used and both lines are up in the above diagram, what happens to the traffic that is traveling from RTR A to RTR B?

The traffic will be load-balanced across both links. X
All traffic will travel over the path associated that is with the higher IP address.
All traffic will travel over the path that is associated with the lower IP address.
The traffic will be unequally load-shared across the links depending on the physical line attributes.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
When configuring dialer watch, why is it advantageous to configure a small value for the dialer idle-timeout command?

The router should periodically check whether the primary link has been re-established at the expiration of each idle timeout. X
The router can quickly use the backup link for other profiles if no interesting traffic is traversing it.
The router should activate the backup link for short durations to check for incoming traffic at the expiration of each idle. timeout.
The router can use the backup link for load sharing if the primary link returns at the expiration of the idle timeout.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
When the backup delay is configured, what does disable-delay specify in the command?

the number of seconds that elapse after the primary line comes up before the Cisco IOS software deactivates the secondary line X
the number of seconds that elapse after the primary line goes down before the Cisco IOS software activates the secondary line
the number of seconds that the primary line stays down after the Cisco IOS software activates the secondary line
the number of seconds that elapse after the secondary line comes up before the Cisco IOS software deactivates the primary line
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
In the following command, what does the number 60 represent?

Router(config-if)# backup delay 30 60

the number of seconds that elapse after the primary line goes down before the Cisco IOS software activates the secondary line
the number of seconds that the primary line stays down after the Cisco IOS software activates the secondary line
the number of seconds that elapse after the primary line comes up before the Cisco IOS software deactivates the secondary line X
the number of seconds that elapse after the secondary line comes up before the Cisco IOS software deactivates the primary line
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
What is the purpose of the the keyword never when configuring backup delay?

It enables the primary line to remain active after it is activated.
It enables the secondary line to remain active after it is activated.
It prevents the primary line from being activated or deactivated.
It prevents the secondary line from being activated or deactivated. X
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Which set of router commands is required to turn on unequal-cost load sharing so that RTR A will select the path A-B-E as well as the lowest cost path A-C-E to Network X?

RTRA(config)# router eigrp 1 X
RTRA(config-router)# variance 2 X

RTRA(config)# router eigrp 1
RTRA(config-router)# variance 1

RTRA(config)# router eigrp 1
RTRA(config-router)# neighbor RTRC 20

RTRA(config)# router eigrp 1
RTRA(config-router)# neighbor RTRB 10
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
In the following configuration, what does the number 2 represent?

router(config-if)# backup load 2 1

The primary line will be activated when the backup line falls below a threshold of 2 percent.
The backup line will be activated when the primary line exceeds a threshold of 2 percent. X
The backup line will be activated when the primary line exceeds a threshold of 20 percent.
The primary line will be activated when the backup line falls below a threshold of 20 percent.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Which IOS command is used to specify an interface for backup?

router(config)# interface backupinterface-type number
router(config)# backup interfaceinterface-type number
router(config-if)# backup interfaceinterface-type number X
router(config-if)# interface backupinterface-type number
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
When defining interesting traffic in a dialer watch configuration, why should routing protocol traffic be denied?

to prevent the back up line from being advertised in the routing protocol
to prevent periodic Hello packets from resetting the idle timeout X
to prevent periodic Hello packets from enabling the backup line
to allow the static route to take precedence over the routing protocol
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
When using OSPF, what happens to the traffic traveling from RTR A to RTR B when both lines are up?

The traffic will be load-balanced.
All traffic will travel over the path with the higher cost.
The traffic will travel over both paths.
All traffic will travel over the path with the lower cost. X
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
When the backup delay is configured, what does the keyword enable-delay modify?

the number of seconds that elapse after the primary line comes up before the Cisco IOS software deactivates the secondary line
the number of seconds that elapse after the primary line goes down before the Cisco IOS software activates the secondary line X
the number of seconds that the primary line stays down after the Cisco IOS software activates the secondary line
the number of seconds that elapse after the secondary line comes up before the Cisco IOS software deactivates the primary line
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
RTR A depends on dynamic routing protocol information to route to Network X. Which backup method would activate the ISDN interface to RTR D in the event that Network X is no longer available in the routing table on RTR A?

floating static
dialer watch X
backup load
backup delay
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Which technology allows a router to monitor the existence of a specified route in the routing table, and when that route is not present, initiate a dial-up backup link?

floating static route
backup load command
load-threshold command
dialer watch X
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
When backup load is configured, what is the purpose of the enable-threshold portion of the following command syntax?

Router(config-if)# backup load {enable-threshold | never} {disable-load | never}

the percentage of the primary line that must be exceeded before the backup line is deactivated
the percentage of the primary line that must be exceeded before the backup line is activated X
the length of time that the primary line must be exceeded before the backup line is deactivated
the length of time that the primary line must be exceeded before the backup line is activated
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Which dial backup IOS commands are used to define the period of time to wait before the backup link is enabled?

Router(config-if)# delay interface {enable-delay | never} {disable-delay | never}
Router(config-if)# backup delay {enable-delay | never} {disable-delay | never} X
Router(config)# delay interface {enable-delay | never} {disable-delay | never}
Router(config)# backup delay {enable-delay | never} {disable-delay | never}
