CCNP 2: Remote Access Chapter 6

1
When split-horizon updates are needed to protect against routing loops, what is the recommended Frame Relay configuration?

with the ip split-horizon command

with a full mesh

with subinterfaces

as a star by using a partial mesh*

with the ip unnumbered interface command



2
The Frame Relay LMI includes support for which items? (Choose three.)

a keepalive mechanism*

a status mechanism*

local addressing

a multicast mechanism*

a unicast mechanism



3
A Cisco router is configured with the command encapsulation frame-relay on an interface. If both Cisco and non-Cisco equipment are installed at the destination, what is required to ensure communication with the non-Cisco equipment?

they must selectively configure encapsulation-type per DLCI*

they must use dynamic configuration

they must use Inverse ARP

they must use LMI type q933



4
Which Frame Relay network topology provides a multipoint PVC connection by using a single interface?

bus

partial mesh

full mesh

Star*



5
Which command displays the LMI traffic statistics that show the number of status messages that are exchanged between the local router and the Frame Relay switch?

show interfaces serial

show frame-relay pvc

show frame-relay map

show frame-relay lmi*



6
Which functions does the broadcast keyword provide when it is used with the frame-relay map command? (Choose three.)

forwards broadcasts when multicasting is enabled

forwards broadcasts when multicasting is not enabled*

simplifies the configuration of OSPF for broadcast networks

provides regular routing-table updates*

simplifies the configuration of OSPF for nonbroadcast networks*



7
What information is already known by the router with Inverse ARP?

Layer 3 IP address and the DLCI

Layer 2 DLCI*

MAC address and DLCI

Layer 3 IP address



8
Which possible PVC states will LMI report as the status of a configured PVC? (Choose three.)

listening

Active*

stopped

Inactive*

Deleted*

down



9
When does a Frame Relay map need to be created manually?

the DLCI-to-Layer 3 address table overflows

multicast is used in the Frame Relay environment

support for LMI autosensing and Inverse ARP are absent*

Inverse ARP is manually configured



10
Which protocol is a signaling standard between the DTE and the Frame Relay switch?

DLCI

LCI

LMI*

FRAD



11
Which command can be used to configure the Frame Relay circuit number into a router?

frame-relay map 05QHD101545-080TCOM-002

frame-relay circuit 05QHD101545-080TCOM-002

frame-relay interface 05QHD101545-080TCOM-002

description Circuit 05QHD101545-080TCOM-002*



12
What is the connection between the customer and the service provider known as when using Frame Relay?

DTE

DCE

NNI

UNI*



13
Which command displays the current map entries and information about the connections?

show interfaces serial

show frame-relay pvc

show frame-relay map*

show frame-relay lmi



14
Which technology advancement makes Frame Relay the preferred replacement for X.25?

connection-oriented data-link technology

error-free digital transmission*

windowing and retransmission mechanisms

comprehensive error correction



15
What is the most popular Frame Relay topology?

bus

full mesh

star or hub and spoke*

partial mesh


16
Which command is required for all point-to-point subinterfaces?

ip unnumbered interface

frame-relay interface-dlci*

frame-relay map

ip split-horizon



17
Which issue is critical to a partial mesh NBMA Frame Relay network design?

broadcasts

multicasts

split-horizon updates

routing updates*



18
To configure basic Frame Relay using Inverse ARP and LMI autosensing, which two tasks should be accomplished? (Choose two.)

configure a Frame Relay map

configure a Layer 3 address*

configure a Layer 2 address (DLCI)

set the encapsulation type to Frame Relay*



19
What identifies the Frame Relay virtual circuit?

FRAD

DCE

LCI

DLCI*



20
When would an SVC be used?

for frequent and consistent data transfer

for a permanently established connection

for sporadic data transfer*

for secure data transfer
