What message field is used by TCP to reassemble and reorder received segments?

Explanation: At the transport layer, TCP uses the sequence numbers in the header of each TCP segment to reassemble the segments into the correct order.

Which of the following characteristics are associated with UDP sessions?

Which two characteristics are associated with UDP sessions? (Choose two.)

  • Destination devices receive traffic with minimal delay.
  • Transmitted data segments are tracked.
  • Destination devices reassemble messages and pass them to an application.
  • Received data is unacknowledged.
  • Unacknowledged data packets are retransmitted.

What important information is added to the TCP IP transport layer?

What important information is added to the TCP/IP transport layer header to ensure communication and connectivity with a remote network device? Explanation: The destination and source port numbers are used to identify exactly which protocol and process is requesting or responding to a request.

What does TCP do if the sending source detects network?

What does TCP do if the sending source detects network congestion on the path to the destination? The source will decrease the amount of data that it sends before it must receive acknowledgements from the destination.

What happens if part of an FTP message?

What happens if part of an FTP message is not delivered to the destination? The message is lost because FTP does not use a reliable delivery method. The FTP source host sends a query to the destination host. The part of the FTP message that was lost is re-sent.

What does a client do when it has UDP data to send?

Explanation: When a client has UDP datagrams to send, it just sends the datagrams.

Which layer of the TCP IP is responsible for formatting compressing and encrypting data?

The presentation layer The presentation layer is responsible for translation, encryption, and compression of data.

  • meeting the reliability requirements of applications, if any.
  • multiplexing multiple communication streams from many users or applications on the same network.
  • identifying the applications and services on the client and server that should handle transmitted data.

When should an administrator establish a network baseline?

Explanation: An effective network baseline can be established by monitoring the traffic at regular intervals. This allows the administrator to take note when any deviance from the established norm occurs in the network.

What happens if the first packet of an FTP 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.

Which layer is responsible for end to end delivery explain?

Transport
Transport- The fourth layer of the OSI model, responsible for reliable end-to-end delivery and error recovery.

What happens if part of an FTP message is lost?

The part of the FTP message that was lost is re-sent. What happens if part of an FTP message is not delivered to the destination? – The message is lost because FTP does not use a reliable delivery method. – The FTP source host sends a query to the destination host. – The part of the FTP message that was lost is re-sent.

What happens if a TFTP request is not received?

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.

Why do FTP messages have sequence and acknowledgment numbers?

Because FTP uses TCP as its transport layer protocol, sequence and acknowledgment numbers will identify the missing segments, which will be re-sent to complete the message. A host device needs to send a large video file across the network while providing data communication to other users.

Why does FTP use TCP as its transport layer protocol?

Explanation: Because FTP uses TCP as its transport layer protocol, sequence and acknowledgment numbers will identify the missing segments, which will be re-sent to complete the message. 11. What type of applications are best suited for using UDP?
