Which DLCI will be used to send the ping? 110  115 220 225 2 Which methods are used to minimize heavy traffic on a Frame Relay network? (Choose two.) FRADs or routers set ECN bits to request that the Frame Relay switch reduce the flow of frames on the link. Windowing is used to reduce the size of the frames sent across the link. The Frame Relay switch will drop low priority packets that have the DE bit set.  When a switch sees its queue increasing, it notifies DTEs to reduce the flow of traffic.  If congestion occurs, all frames are dropped until the congestion clears. 3 What is the purpose of the FCS field in a Frame Relay frame? It serves to distinguish one frame from the next. It is used to signal network congestion. It is used to detect if the frame has been corrupted and should be discarded.  It determines which VC should be used for transmission. 4 What does a DLCI of 1023 indicate about a frame? The LMI type is ANSI. The LMI type is IETF. The LMI type is Cisco. The LMI type is Q933a. The encapsulation is Cisco. The encapsulation is IETF. 5 Which of the following DLCIs are reserved? 16 127 255 1023  2048 6 Which of the following 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 7 What is created between two DTEs in a Frame Relay network? switched parallel circuit permanent virtual circuit  limited access circuit ISDN circuit Frame Relay circuit 8 Which statement identifies a reason for using subinterfaces in Frame Relay networks? Subinterfaces overcome routing update and split-horizon issues that occur with multipoint physical interfaces.  A subinterface does not require an IP address and therefore saves address space. Multipoint subinterfaces override the split-horizon rules and allow broadcast traffic to be forwarded by default. Subinterfaces provide greater reliability and reachability in Frame Relay networks by requiring a mesh topology for network configurations. Subinterfaces increase the number of DLCIs that can be configured in a Frame Relay network. 9 Which features make Frame Relay technology a cost-effective alternative to a mesh of access lines? (Choose three.) allows a single interface to support multiple PVCs  minimizes the equipment required to be purchased by the customer  requires one router interface for each PVC allows the customer to do dial on demand routing over analog lines rather than paying for access lines allows the customer to pay for the average bandwidth requirement rather than the maximum bandwidth requirement  10 Which commands were added to the configuration to produce the output shown in the graphic? (Choose two.) Router(config)# ip route 192.168.192.4 255.255.255.0 17 broadcast Router(config-if)# frame-relay lmi-type cisco 17 Router(config-if)# frame-relay map ip 192.168.192.4 17 broadcast  Router(config-if)# ip address 192.168.192.4 255.255.255.0 DLCI 17 static Router(config-if)# interface S0/0.1 point-to-point Router(config-if)# encapsulation frame-relay cisco  11 Which of the following statements are true about a basic Frame Relay WAN connection between a customer and the service provider? (Choose two.) DTE devices such as routers and FRADs transmit user data.  DTE devices such as Frame Relay switches transport the data between DTE devices. An Ethernet connection between the router and the frame relay switch allow access to the frame relay network. Serial connections between the customer and the frame relay network are used to transport data.  The Frame Relay WAN is a mesh of interconnected routers. 12 How does Frame Relay technology 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. 13 Why are full mesh topologies seldom found in large Frame Relay networks? Additional hardware is required to achieve the mesh. The additional virtual circuits slow the link access speeds. The required number of links becomes prohibitive.  Additional interfaces are required since each can only support 10 virtual circuits. The speed of transmission slows in inverse proportion to the square of the number of links. 14 Which bits are set in the data frames to request that a device reduce the flow of data sent to or from a Frame Relay switch? EIR bits ECN bits  CIR bits DE bits Window bits 15 Which data link layer protocol is used to carry frames across a Frame Relay link?

What can be concluded from the output shown in the graphic? (Choose three.) The output in the debug frame-relay lmi command will indicate status 0x2 for DLCI 18.  DLCI 16 was programmed on the switch, but the remote router may be misconfigured.  The frame relay switch is sending LMI status messages about DLCI 16 to the Singapore router.  Congestion has been experienced on DLCI 18. Some packets have been set to be dropped if congestion is experienced on the PVC. 17 When troubleshooting a frame-relay connection, an administrator entered the show interface s0/0 command and received the output shown in the graphic. The line protocol is down. Which of the following are possible reasons for this problem? (Choose two.) The cable between the CSU/DSU and the router is disconnected.

A single multipoint subinterface is used to establish PVC connections to multiple physical interfaces on remote routers. Each multipoint link is in its own subnet. The physical interface does not have an IP address.  Split-horizon is disabled allowing routing updates to be re-transmitted on every subinterface. Multipoint subinterfaces require the encapsulation frame-relay command to be issued individually for each subinterface to operate correctly. 19 Which of the following occurs when the command frame-relay map ip 10.1.1.1 22 is configured on the router? (Choose two.) DLCI 22 will replace the MAC address in the ARP table for entry 10.1.1.1 The remote circuit with DLCI 22 can receive a ping. Inverse-ARP will be used to add an entry for 10.1.1.1 into the frame-relay map table using DLCI 22. Pings to 10.1.1.1 will be sent on the circuit labeled DLCI 22.  The router will use DLCI 22 to forward data to 10.1.1.1.  20 How is a permanent virtual circuit defined in a Frame Relay network that is carrying IP traffic? It is given a fixed locally significant identification number.  It has a specific IP address. It is identified by the MAC address of the router interface.
