the combination of the resource and destination IP address and source and location Ethernet address
the combination of a resource IP resolve and harbor number or a destination IP resolve and port number*
the mix of the resource and location sequence and acknowledgment numbers
the mix of the source and destination sequence numbers and also port numbers2. A host machine needs come send a large video file across the network while providing data interaction to various other users. Which feature will allow different communication streams to take place at the exact same time, without having a solitary data stream utilizing all easily accessible bandwidth?
acknowledgments3. A host device sends a data packet come a web server via the HTTP protocol. What is used by the carry layer to happen the data stream come the suitable application top top the server?
source port number
destination harbor number*4. What is a beneficial feature of the UDP transport protocol?
acknowledgment of got data
fewer delays in transmission*
tracking of data segments using sequence numbers
the capability to retransmit lost data5. I m sorry scenario describes a function detailed by the transfer layer?
A college student is using a classroom VoIP call to call home. The unique identifier melted into the phone is a deliver layer address used to contact an additional network device on the exact same network.
You are watching: Compared to udp, what factor causes additional network overhead for tcp communication?
A college student is playing a quick web-based movie with sound. The movie and also sound room encoded in ~ the deliver layer header.
A student has actually two web web browser windows open in bespeak to access two internet sites. The transfer layer ensures the correct net page is delivered to the correct web browser window.*
A that company worker is accessing a web server located on a this firm network. The transfer layer styles the display so the net page shows up properly no issue what machine is being supplied to watch the web site.6. What is the complete selection of TCP and UDP famous ports?
0 come 255
0 to 1023*
256 – 1023
1024 – 491517. What walk a customer application choose for a TCP or UDP resource port number?
a random value in the famous port range
a random worth in the range of the registered ports*
a predefined worth in the well-known port range
a predefined value in the variety of the registered ports8. Compared to UDP, what factor causes added network overhead because that TCP communication?
network website traffic that is brought about by retransmissions*
the identification of applications based upon destination harbor numbers
the encapsulation into IP packets
the checksum error detection9. Which transport layer feature is provided to insurance session establishment?
UDP ACK flag
TCP 3-way handshake*
UDP sequence number
TCP port number10.Which 2 flags in the TCP header are supplied in a TCP three-way handshake to develop connectivity in between two network devices? (Choose two.)
URG11. Which variable determines TCP window size?
the quantity of data to be transmitted
the variety of services contained in the TCP segment
the amount of data the location can procedure at one time*
the quantity of data the source is qualified of sending out at one time12. During a TCP session, a destination device sends one acknowledgment number to the resource device. What go the acknowledgment number represent?
the total variety of bytes that have been received
one number more than the succession number
the following byte the the location expects to receive*
the last sequence number the was sent by the source13. A computer is downloading a large document from a server. The TCP home window is 1000 bytes. The server is sending out the file using 100-byte segments. How many segments will certainly the server send before it calls for an acknowledgment native the PC?
1000 segments14. Which two TCP header fields are supplied to check receipt the data?
acknowledgment number*15. What wake up if the very first packet that a TFTP deliver is lost?
The customer will wait indefinitely for the reply.
The TFTP application will certainly retry the request if a reply is not received.*
The next-hop router or the default gateway will provide a reply through an error code.
The transport layer will certainly retry the query if a answer is no received.16. What does a client do when it has UDP datagrams to send?
It simply sends the datagrams.*
It queries the server to view if the is prepared to receive data.
It sends out a streamlined three-way handshake to the server.
It sends out to the server a segment with the SYN flag collection to synchronize the conversation.17. A technician wishes to use TFTP to carry a large file from a record server come a far router. I beg your pardon statement is correct about this scenario?
The file is segmented and also then reassembled in the correct order through TCP.
The paper is segmented and then reassembled in the exactly order at the destination, if necessary, through the upper-layer protocol.*
The record is no segmented, because UDP is the deliver layer protocol the is provided by TFTP.
Large files must be sent by FTP no TFTP.18. To fill in the blank.
During a TCP session, the SYN flag is used by the customer to request communication with the server.19. To fill in the blank using a number.
A complete of 4 messages are exchanged during the TCP session termination procedure between the client and the server.
