What is different about using IPv6 with Frame Relay compared to using IPv4?
The protocol to obtain the Layer 3 address of the opposite device
The encapsulation method
The length of the Layer 2 and Layer 3 headers
The IP address and the length of the DLCI number
The maximum average data rate that a service provider guarantees to a customer is known as the
CIR
What are two reasons Frame Relay is more cost-effective than leased lines?
Time division multiplexing
Uses less equipment
Optimized packet routing
Shares bandwidth across a large customer base
Dynamic IP addressing
In what situation would it be best to use Frame Relay subinterfaces?
When IPv6 is used
when VLSM is used
When static routing is used
Any time EIGRP or OSPF is used across the Frame Relay cloud
A router in a Frame Relay network needs to forward a message received from a host. What two methods does the router use to identify the correct VC to forward the message?
The router forwards the frame to all ports in the network and learns the address from the reply frame.
The destination host IP address is embedded in the DLCI.
The router searches Inverse ARP tables for maps of DLCIs to IP addresses.
A table of static mappings can be searched.
The router broadcasts a request for the required IP address.
Used to obtain neighbor IP address
A unique connection number
Used as a result of congestion
A connection between two sites
What is an advantage of configuring subinterfaces in a Frame Relay environment?
Makes the DLCIs globally significant
Eliminates the need for using Inverse ARP
reduces split horizon issues
Improves flow control and bandwidth usage
If Inverse ARP is not available for use, how can a network administrator still provide a Frame Relay connection to the service provider and forward routing updates?
Use dynamic mapping.
Use static mapping with the broadcast keyword.
Use an LMI type of cisco.
Use the ietf keyword when activating Frame Relay.
What DLCI number is used to send traffic from RouterA and what is the IP address of RouterB?
50 and 10.10.10.2
103 and 10.10.10.1
50 and 10.10.10.1
103 and 10.10.10.2
Which bit is set by a Frame Relay switch to inform the source station that there is congestion on the network?
BECN
CIR
DE
FCS
FECN
What are three mechanisms used by Frame Relay to reduce network overhead caused by congestion? (Choose three.)
BECN
NTP
DLCI
FECN
DE
per-VC flow control
LMI
What keyword is used in a Frame Relay static map configuration when OSPF is used among various sites of a corporation?
broadcast
cisco
Ietf
Ospf
How are Frame Relay virtual circuits identified?
CIR
DLCI
Mac
VPI
Spid
Which statement is a correct deduction from the Frame Relay configuration that is shown?
The router is using a Cisco proprietary encapsulation.
The router will dynamically learn the LMI type from the Frame Relay switch.
The router can communicate with a non-Cisco Frame Relay switch.
The router Frame Relay interface is configured for point-to-point subinterfaces.
