3.The HoldDown
Timer used in Distance Vector protocols:
A.Sets the time limit of how long a router may keep a packet in its buffer, if the routing protocol is in the
process of converging
B.Determines the number of seconds a router will wait before sending another update to neighbor routers
C.Sets a specific period for routers to neither accept nor advertise a route from a destination where an
original route was recently lost

Correct:C
4.Click the Exhibit button. PE1 and PE2 are connected to the MPLS cloud. All MPLS labels from
PE1 and PE2 are working. Observing the shown topology, will this scenario work?
A.This scenario will not work because Gigabit Ethernet can’t be connected to FastEthernet over MPLS.
B.This scenario will work because the issues concerning Gigabit and FastEthernet over MPLS with
default behavior should not make any difference.
C.This scenario will not work because Gigabit usually has MTU over 9000 and FastEthernet 1500.
D.This scenario will not work because one side has dot1q header and another side is in port mode.
E.This scenario will work by configuring PWE Class using the Interworking feature. By default, the MTU
on each side is 1500, so this is an acceptable solution.
Correct:E

6.Which commands are valid in ethernet or ethernet VLAN attachment circuits?
A.match cos
B.match ethernet cos
C.match sourcemac

Correct:A D
7.OSPF is defined on a Frame Relay interface providing pointtomultipoint
connections. The
remote neighbors can reach this central site, but are complaining of routing failures between each
of the remote sites. The central router has all the routes for each remote site. Based on this
information, what can be diagnosed as the biggest potential problem?
A.An oversubscribed
Frame Relay switch will cause some packet loss.
B.There are problems in the use of OSPF Authentication.
C.There is an incorrect selection of the Designated Router.
D.There is an incorrect DLCI assigned on a pointtopoint
subinterface.
Correct:C
8.EIGRP applies the principle of Feasible Successor (FS) in resolving a new path to a lost route.
What statement regarding the FS is correct?
A.Information is stored for the FS as part of the LinkState
Routing updates forwarded for EIGRP.
B.EIGRP estimates the FS from each neighbor for each network after an exchange of database
information during the normal update process. It uses this information for path selection when a route is
lost.
C.When EIGRP is notified that a route is lost, it will always send requests to each neighbor for ways to
reach the lost route. The neighbor that returns the best path will qualify as the FS.
D.EIGRP nominates a central router as the FS for all lost routes during configuration.
Correct:B
9.What technology allows transporting Layer2 attachment circuits over IPonly
backbones?

C.Packet Cell Relay AAL5 Trunk Mode
D.Packed Cell Relay Trunk mode
E.AAL2oMPLS
Correct:A C

D.Change Status
E.Call Reference
Correct:A

B.There is a partial mesh of pseudowires.
C.Only L2TPv3 can be used for pseudowire establishment.
D.STP runs in the core.
E.There is splithorizon
to avoid loops.
Correct:A E
13.How many bits does TCI contain?
A.1
B.3
C.6
D.12
E.16
F.20
Correct:E
14.What command is used for Interworking configuration?
A.`interworking {etherner | ip} in interface config mode.
B.`interworking {etherner | ip} in pseudowireclass
config mode.
C.`Interworking {bridged | routed} in l2tpclass
mode.
D.`{ip | ethernet}Interworking in pseudowireclass
config mode.
Correct:B
15.A router is set to boot from flash, but cannot find boot commands in the configuration. Also,
valid files do not exist in the default flash device. The router will:
A.Boot from ROM, since there are no valid sources
B.Try to boot from the network, using a default filename
C.Terminate the boot process with an error message
D.Try to boot from the network, then boot from ROM as a backup
Correct:D
