The hash function is one way and irreversible. Explanation: A cryptographic hash function should have the following properties:The input can be any length. The output has a fixed length. The hash value is relatively easy to compute for any given input. The hash is one way and not reversible. The hash is collision free, meaning that two different input values will result in different hash values A security specialist is tasked to ensure that files transmitted between the headquarters office and the branch office are not altered during transmission.

Applications that use UDP are always considered unreliable. UDP reassembles the received datagrams in the order they were received. Explain: 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. What does a client do when it has UDP datagrams to send? It just sends the datagrams. 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. Explain: 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 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.

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.

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.

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.
