What is an advantage of Frame Relay WAN technology compared with leased lines?
It supports both voice and data traffic.
It uses one interface to connect to several remote sites.
It provides permanent dedicated capacity to the customers.
It offers a guaranteed direct electrical circuit from end to end.
A router interface connects to a Frame Relay network over a preconfigured logical circuit that does not have a direct electrical connection from end to end. Which type of circuit is being used?
SVC
Full mesh
PVC
Hub and spoke
Dedicated leased line
Which technology allows a Layer 3 IPv4 address to be dynamically obtained from a Layer 2 DLCI?
Inverse Address Resolution Protocol
Inverse Neighbor Discovery
Address Resolution Protocol
Neighbor Discovery
A network administrator has statically configured the LMI type on the interface of a Cisco router that is running Cisco IOS Release 11.2. If the service provider modifies its own LMI type in the future, what step must the network administrator take?
The network administrator must modify the keepalive time interval to maintain connectivity with the LMI type of the service provider.
The network administrator simply has to verify connectivity with the provider, because the router has an LMI autosensing feature that automatically detects the LMI type.
The network administrator must statically set the LMI type to be compatible with the service provider.
The network administrator does not have to do anything, because all LMI types are compatible with one another.
Which two functions are provided by the Local Management Interface (LMI) that is used in Frame Relay networks? (Choose two.)
Simple flow control
Error notification
Congestion notification
Mapping of DLCIs to network addresses
Exchange of information about the status of virtual circuits
A network administrator of a large organization is designing a Frame Relay network. The organization needs redundancy between some key sites but not all. What WAN topology should the administrator choose to meet their needs?
Extended star
Full mesh
Star
Partial mesh
Which three notification mechanisms are used when congestion is present in a Frame Relay network? (Choose three.)
BECN
CIR
DE
DLCI
FECN
Inverse ARP
Why would a customer request a Frame Relay circuit with a CIR of zero?
To have better QoS
To have a backup circuit for critical data transmissions
To have a link with reduced costs
To have a circuit used for voice traffic
To have a circuit used for network management traffic
Refer to the exhibit. Which two statements are correct? (Choose two.)
The Frame Relay map was set by using the command frame-relay map.
The IPv4 address of interface S0/1/0 on RA is 192.168.1.2.
The DLCI that is attached to the VC on RA to RB is 62.
The IPv4 address of interface S0/1/1 on RB is 192.168.1.2.
A network administrator uses the following command to configure a Frame Relay connection on a router towards the service provider: R1(config-if)# frame-relay map ip 209.165.200.225 102 broadcast What is the purpose of using the broadcast keyword?
To enable dynamic IP address-to-DLCI mapping
To enable VoIP packet transmission across the link
To support dynamic routing protocol updates across the link
To support IP address to MAC address resolution for the interface in the service provider site
Which three actions can be taken to solve Layer 3 routing protocol router reachability issues when using Frame Relay? (Choose three.)
Use subinterfaces.
Disable Inverse ARP.
Disable split horizon.
Use a full mesh topology.
Configure static DLCI mappings.
Use the keyword cisco as the LMI type.
When would the multipoint keyword be used in Frame Relay PVCs configuration?
When global DLCIs are in use
When using physical interfaces
When multicasts must be supported
When participating routers are in the same subnet
A network engineer has issued the interface serial 0/0/1.102 point-to-point command on a router that will be communicating with another router over a Frame Relay virtual circuit that is identified by the DLCI 102. Which two commands would be appropriate for the network engineer to issue next? (Choose two.)
No ip address
No shutdown
Encapsulation frame relay
Frame-relay interface-dlci 102
Ip address 10.1.1.10 255.255.255.252
Which two Frame Relay router reachability issues are resolved by configuring logical subinterfaces? (Choose two.)
Frame Relay is unable to map a remote IP address to a DLCI.
Link-state routing protocols are unable to complete neighbor discovery.
LMI status inquiry messages sent to the network are not received.
Inverse ARP fails to associate all IP addresses to the correct DLCIs.
Distance vector routing protocols are unable to forward routing updates back out the incoming interface to other remote routers.
The show frame-relay pvc command is best utilized to display the number for which type of packets that are received by the router?
LMI status messages
Inverse ARP messages
Inverse Neighbor Discovery messages
FECN and BECN messages
Refer to the exhibit. A network administrator issues the show frame-relay map command to troubleshoot the Frame Relay connection problem. Based on the output, what is the possible cause of the problem?
The S0/0/1 interface of the R2 router is down.
The IP address on S0/0/1 of R3 is configured incorrectly.
Inverse ARP is providing false information to the R1 router.
The Frame Relay map statement on the R3 router for the PVC to R2 is configured with an incorrect DLCI number.
The S0/0/1 interface of the R2 router has been configured with the encapsulation frame relay ietf command.
Refer to the exhibit. A network administrator is configuring Frame Relay subinterfaces on R1. A distance vector routing protocol has also been configured. Data is routing successfully from R1 to networks that are connected to R2, R3, and R4, but routing updates between R2 and R3 are failing. What is the possible cause of this failure?
Subinterfaces cannot be used on multipoint Frame Relay links.
Two DLCI identifiers cannot be configured on one subinterface.
Multipoint Frame Relay networks cannot be used with this IP addressing scheme.
Split horizon is preventing successful routing table updates on the multipoint link.
