As data travels on the media in a stream of 1s and 0s how does a receiving node identify the beginning and end of a frame? The transmitting node inserts start and stop bits into the frame. The transmitting node sends a beacon to notify that a data frame is attached. The receiving node identifies the beginning of a frame by seeing a physical address. The transmitting node sends an out-of-band signal to the receiver about the beginning of the frame. Explanation: When data travels on the media, it is converted into a stream of 1s and 0s. The framing process inserts into the frame start and stop indicator flags so that the destination can detect the beginning and end of the frame. If the two values do not match, then the frame is discarded. Fill in the blank.

- Which two Frame Relay router reachability issues are resolved by configuring logical subinterfaces? Choose two. Link-state routing protocols are unable to complete neighbor discovery. LMI status inquiry messages sent to the network are not received. 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? 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? Inverse ARP is providing false information to the R1 router. 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? 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. Fill in the blank. Use an acronym. The encapsulation frame-relay ietf command enables Frame Relay encapsulation and allows connection to a device from a different vendor. Match the characteristics with the type of WAN link. Not all options are use.
- What does TCP do if the sending source detects network congestion on the path to the destination? The source host will send a request for more frequent acknowledgments to the destination. The source will decrease the amount of data that it sends before it must receive acknowledgements from the destination. The destination will request retransmission of the entire message. The source will acknowledge the last segment that is sent and include a request for a smaller window size in the message.
- Explanation: If the source determines that TCP segments are either not being acknowledged or not acknowledged in a timely manner, then it can reduce the number of bytes it sends before receiving an acknowledgment. Notice that it is the source that is reducing the number of unacknowledged bytes it sends. This does not involve changing the window size in the segment header. What is a characteristic of UDP? UDP datagrams take the same path and arrive in the correct order at the destination. Applications that use UDP are always considered unreliable. UDP reassembles the received datagrams in the order they were received. UDP only passes data to the network when the destination is ready to receive the data. Explanation: UDP has no way to reorder the datagrams into their transmission order, so UDP simply reassembles the data in the order it was received and forwards it to the application.
- It just sends the datagrams. It queries the server to see if it is ready to receive data. It sends a simplified three-way handshake to the server. It sends to the server a segment with the SYN flag set to synchronize the conversation. Explanation: When a client has UDP datagrams to send, it just sends the datagrams. What happens if the first packet of a TFTP transfer is lost? The client will wait indefinitely for the reply. The TFTP application will retry the request if a reply is not received. The next-hop router or the default gateway will provide a reply with an error code. The transport layer will retry the query if a reply is not received. A host device is receiving live streaming video. How does the device account for video data that is lost during transmission?
- The device will immediately request a retransmission of the missing data. The device will use sequence numbers to pause the video stream until the correct data arrives. The device will delay the streaming video until the entire video stream is received. The device will continue receiving the streaming video, but there may be a momentary disruption. Explanation: When TCP is used as the transport protocol, data must be received in a specific sequence or all data must be fully received in order for it to be used.
- TCP will use sequence numbers, acknowledgments and retransmission to accomplish this. However, when UDP is used as the transport protocol, data that arrives out of order or with missing segments may cause a momentary disruption, but the destination device may still be able to use the data that it has received. This technology results in the least amount of network delay by providing minimal reliability. Since live streaming video applications use UDP as the transport protocol, the receiver will continue showing the video although there may be a slight delay or reduction in quality. UDP is the preferred protocol for applications that provide voice or video that cannot tolerate delay. Which three application layer protocols use TCP?
