What is a characteristic of Frame Relay that provides more flexibility than a dedicated line?
Customers use dedicated circuits in increments of 64 kb/s.
Dedicated physical circuits are installed between each site.
The Frame Relay cloud allocates as much bandwidth as required to active PVCs to maintain the connection.
One router WAN port can be used to connect to multiple destinations.
What are the two major criteria that constitute the cost of a Frame Relay circuit? (Choose two.)
circuit management fees
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?
hub and spoke
dedicated leased line
Which Frame Relay topology provides a connection from every site to every other site and maintains a high amount of reliability?
hub and spoke
Which technology allows a Layer 3 IPv4 address to be dynamically obtained from a Layer 2 DLCI?
Address Resolution Protocol
Inverse Neighbor Discovery
Inverse Address Resolution Protocol
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?
administrator must modify the keepalive time interval to maintain
connectivity with the LMI type of the service provider.
The network administrator does not have to do anything, because all LMI types are compatible with one another.
The network administrator must statically set the LMI type to be compatible with the service provider.
network administrator simply has to verify connectivity with the
provider, because the router has an LMI autosensing feature that
automatically detects the LMI type.
Which two functions are provided by the Local Management Interface (LMI) that is used in Frame Relay networks? (Choose two.)
mapping of DLCIs to network addresses
simple flow control
exchange of information about the status of virtual circuits
Which parameter would be specified in a Frame Relay provider contract for a particular company?
Inverse ARP enabled/disabled
Which three notification mechanisms are used when congestion is present in a Frame Relay network? (Choose three.)
Why would a customer request a Frame Relay circuit with a CIR of zero?
to have a circuit used for network management traffic
to have a backup circuit for critical data transmissions
to have better QoS
to have a link with reduced costs
to have a circuit used for voice traffic
Which provider-negotiated parameter would allow a customer to send data above the rate of the bandwidth specified by the CIR?
What is the purpose of applying the command frame-relay map ip 10.10.1.2 110 broadcast?
to support IPv6 traffic over the NBMA network by using DLCI 110
to allow Frame Relay frames to be broadcast over DLCI 110
to allow Frame Relay frames to be broadcast toward host 10.10.1.2
to allow Frame Relay frames to be broadcast on all Frame Relay interfaces
to configure a device with a static Frame Relay map that also allows the forwarding of routing updates
Refer to the exhibit. Which two statements are correct? (Choose two.)
The IPv4 address of interface S0/1/0 on RA is 192.168.1.2.
The IPv4 address of interface S0/1/1 on RB is 192.168.1.2.
The DLCI that is attached to the VC on RA to RB is 62.
The DLCI that is attached to the VC on RB to RA is 62.
The Frame Relay map was set by using the command frame-relay map.
Refer to the exhibit. Which statement is true about Frame Relay traffic on R1?
Traffic that exits subinterface Serial 0/0/0.102 is marked with DLCI 201.
Traffic on Serial 0/0/0 is experiencing congestion between R1 and the Frame Switch.
Traffic that is mapped to DLCI 201 will exit subinterface Serial 0/0/0.201.
Frames that enter router R1 from a Frame Relay neighbor will have DLCI 201 in the frame header.
three actions can be taken to solve Layer 3 routing protocol router
reachability issues when using Frame Relay? (Choose three.)
Disable Inverse ARP.
Use a full mesh topology.
Use the keyword cisco as the LMI type.
Disable split horizon.
Configure static DLCI mappings.
When would the multipoint keyword be used in Frame Relay PVCs configuration?
when multicasts must be supported
when using physical interfaces
when participating routers are in the same subnet
when global DLCIs are in use
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
encapsulation frame relay
ip address 10.1.1.10 255.255.255.252
frame-relay interface-dlci 102
Which two Frame Relay router reachability issues are resolved by configuring logical subinterfaces? (Choose two.)
LMI status inquiry messages sent to the network are not received.
Inverse ARP fails to associate all IP addresses to the correct DLCIs.
Frame Relay is unable to map a remote IP address to a DLCI.
Distance vector routing protocols are unable to forward routing updates back out the incoming interface to other remote routers.
Link-state routing protocols are unable to complete neighbor discovery.
to the exhibit. A network administrator has implemented the show
interfaces serial 0/1/0 command. What can be verified from the displayed
Router R1 connects to multiple sites through the serial 0/1/0 interface.
Router R1 is forwarding traffic on interface serial 0/1/0 using the local DLCI 1023.
Router R1 is not using the default LMI type.
Router R1 has been configured with Frame Relay via the ietf keyword.
show frame-relay pvc command is best utilized to display the number for
which type of packets that are received by the router?
FECN and BECN messages
Inverse Neighbor Discovery messages
Inverse ARP messages
LMI status messages
