We truly value your contribution to the website. 1. What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?
Explain: 2. What type of communication will send a message to all devices on a local area network?
Explain:Broadcast communication is a one-to-all communication. A unicast communication is a one-to-one communication. Multicast is a one-to-many communication where the message is delivered to a specific group of hosts. Allcast is not a standard term to describe message delivery. 3. What process is used to place one message inside another message for transfer from the source to the destination?
Explain:Encapsulation is the process of placing one message format into another message format. An example is how a packet is placed in its entirety into the data field as it is encapsulated into a frame. 4. A web client is sending a request for a webpage to a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to prepare the request for transmission?
Explain:1. HTTP governs the way that a web server and client interact.2. TCP manages individual conversations between web servers and clients.3. IP is responsible for delivery across the best path to the destination. 4. Ethernet takes the packet from IP and formats it for transmission. 5. Which statement is correct about network protocols?
Explain: 6. Which statement is true about the TCP/IP and OSI models?
Explain: 7. What is an advantage of using standards to develop and implement protocols?
Explain: 8. What three application layer protocols are part of the TCP/IP protocol suite? (Choose three.)
Explain: 9. What are proprietary protocols?
Explain: 10. What is an advantage of network devices using open standard protocols?
Explain:
11. Refer to the exhibit. If Host1 were to transfer a file to the server, what layers of the TCP/IP model would be used?
Explain: 12. Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model? (Choose three.)
Explain: 13. At which layer of the OSI model would a logical address be encapsulated?
Explain: 14. At which layer of the OSI model would a logical address be added during encapsulation??
Explain: 15. Which PDU format is used when bits are received from the network medium by the NIC of a host?
Explain: 16. Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model?
Explain:
17. Refer to the exhibit. HostA is attempting to contact ServerB. Which two statements correctly describe the addressing that HostA will generate in the process? (Choose two.)
Explain: 18. Which address does a NIC use when deciding whether to accept a frame?
19. What will happen if the default gateway address is incorrectly configured on a host?
Explain: 20. Which characteristic describes the default gateway of a host computer?
Explain:
21. Match the description to the organization. (Not all options are used.)
ISOC -> The organization promotes the open development, evolution, and use of the internet throughout the world
Explain:
22. Match the protocol function to the description while taking into consideration that a network client is visiting a web site. (Not all options are used.)
Place the options in the following order: managing the individual conversations between web servers and web clients –> transport protocol Explain:When a web client visits a web server, several network communication protocols are involved. These different protocols work together to ensure that the messages are received and understood by both parties. These protocols include the following:Application Protocol – governing the way a web server and a web client interactTransport Protocol – managing the individual conversations between web servers and web clientsInternet Protocol – taking the formatted segments from the transport protocol, encapsulating them into packets, assigning them the appropriate addresses, and delivering them across the best path to the destination hostNetwork Access Protocol – preparing packets to be transmitted over the network media Network Time Protocol is used to synchronize clocks between computer systems. It is not involved in this case.
23. Match each description to its corresponding term. (Not all options are used.) Place the options in the following order:– not scored – message encoding -> the process of converting information from one format into another acceptable for transmission message encapsulation -> the process of placing one message format inside another message format– not scored – message sizing -> the process of breaking up a long message into individual pieces before being sent over the network 24. A computer in a given network is communicating with a specific group of computers. What type of communication is this?
25. Which protocol is responsible for controlling the size and rate of the HTTP messages exchanged between server and client? 26. A user is viewing an HTML document located on a web server. What protocol segments the messages and manages the segments in the individual conversation between the web server and the web client? 27. Which IEEE standard enables a wireless NIC to connect to a wireless AP that is made by a different manufacturer?
28. What is a function of Layer 4 of the OSI model?
29. What is a benefit of using a layered model for network communications?
30. What is the general term that is used to describe a piece of data at any layer of a networking model?
31. Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?
32. What statement describes the function of the Address Resolution Protocol?
33. Which address provides a unique host address for data communications at the internet layer?
34. Which protocol is used by a computer to find the MAC address of the default gateway on an Ethernet network? 35. If the default gateway is configured incorrectly on the host, what is the impact on communications?
36. Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. Based on the configured network, what IP address would PC1 and PC2 use as their default gateway?
37. A user sends an HTTP request to a web server on a remote network. During encapsulation for this request, what information is added to the address field of a frame to indicate the destination?
38. Refer to the exhibit. PC-A and PC-B are both in VLAN 60. PC-A is unable to communicate with PC-B. What is the problem?
39. Which command is used to remove only VLAN 20 from a switch?
