1. Which best describes the benefit of using Frame Relay as opposed to a leased line or ISDN service?
• Customers can define their virtual circuit needs in far greater combinations, with increments as small as 64 kbps.
Customers pay for an end-to-end connection that includes the local loop and the network link.
• Customers only pay for the local loop and the bandwidth they purchase from the network provider.
Connecting new sites requires new lower cost circuit installations when compared to ISDN dialup costs or adding additional
hardware for leased service.
2. What two methods does Frame Relay technology use to process frames that contain errors? (Choose two.)
• Frame Relay services depend on the upper layer protocols to handle error recovery.
It requires the receiving device to request that the sender retransmit erroneous frames.
FECN, BECN, and DE bits are set in the frames to minimize errors.
• The receiving device drops any frames that contain errors without notifying the sender.
The frame relay switch notifies the sender that errors were detected.
3. What best describes the use of a data-link connection identifier (DLCI)?
local address identifying a destination router across a Frame Relay network
• locally significant address used to identify a virtual circuit
logical address identifying the interface between a router and a Frame Relay switch
logical address used to identify the DCE
4. What is created between two DTEs in a Frame Relay network?
ISDN circuit
limited access circuit
switched parallel circuit
• virtual circuit
5. Which two items allow the router to map data link layer addresses to network layer addresses in a Frame Relay network? (Choose two.)
ARP
RARP
Proxy ARP
• Inverse ARP
• LMI status messages
ICMP
