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:Network protocols are implemented in hardware, or software, or both. They interact with each other within different layers of a protocol stack. Protocols have nothing to do with the installation of the network equipment. Network protocols are required to exchange information between source and destination devices in both local and remote networks. 6. Which statement is true about the TCP/IP and OSI models?
Explain:The TCP/IP internet layer provides the same function as the OSI network layer. The transport layer of both the TCP/IP and OSI models provides the same function. The TCP/IP application layer includes the same functions as OSI Layers 5, 6, and 7. 7. What is an advantage of using standards to develop and implement protocols?
Explain:Standards-based protocols enable products from different manufacturers to interoperate successfully. Standards-based protocols enable many manufacturers to implement that protocol. If different manufacturers implement different requirements within the same protocol, then their products will not be interoperable. 8. What three application layer protocols are part of the TCP/IP protocol suite? (Choose three.) Explain:DNS, DHCP, and FTP are all application layer protocols in the TCP/IP protocol suite. ARP and PPP are network access layer protocols, and NAT is an internet layer protocol in the TCP/IP protocol suite. 9. What are proprietary protocols?
Explain:Proprietary protocols have their definition and operation controlled by one company or vendor. Some of them can be used by different organizations with permission from the owner. The TCP/IP protocol suite is an open standard, not a proprietary protocol. 10. What is an advantage of network devices using open standard protocols?
Explain:An advantage of network devices implementing open standard protocols, such as from the TCP/IP suite, is that clients and servers running different operating systems can communicate with each other. Open standard protocols facilitate innovation and competition between vendors and across markets, and can reduce the occurrence of monopolies in networking markets. 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:The TCP/IP model contains the application, transport, internet, and network access layers. A file transfer uses the FTP application layer protocol. The data would move from the application layer through all of the layers of the model and across the network to the file server. 12. Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model? (Choose three.)
Explain:The TCP/IP model consists of four layers: application, transport, internet, and network access. The OSI model consists of seven layers: application, presentation, session, transport, network, data link, and physical. The top three layers of the OSI model: application, presentation, and session map to the application layer of the TCP/IP model. 13. At which layer of the OSI model would a logical address be encapsulated?
Explain:Logical addresses, also known as IP addresses, are encapsulated at the network layer. Physical addresses are encapsulated at the data link layer. Port addresses are encapsulated at the transport layer. No addresses are encapsulated at the physical layer. 14. At which layer of the OSI model would a logical address be added during encapsulation?
Explain:Logical addresses, also known as IP addresses, are encapsulated at the network layer. Physical addresses are encapsulated at the data link layer. Port addresses are encapsulated at the transport layer. No addresses are encapsulated at the physical layer. 15. Which PDU format is used when bits are received from the network medium by the NIC of a host? Explain:When received at the physical layer of a host, the bits are formatted into a frame at the data link layer. A packet is the PDU at the network layer. A segment is the PDU at the transport layer. A file is a data structure that may be used at the application layer. 16. Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model? Explain:At the transport layer, a host computer will de-encapsulate a segment to reassemble data to an acceptable format by the application layer protocol of the TCP/IP model. 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:When a host needs to send a message to another host located on the same network, it can forward the message directly. However, when a host needs to send a message to a remote network, it must use the router, also known as the default gateway. This is because the data link frame address of the remote destination host cannot be used directly. Instead, the IP packet has to be sent to the router (default gateway) and the router will forward the packet toward its destination. Therefore, if the default gateway is incorrectly configured, the host can communicate with other hosts on the same network, but not with hosts on remote networks. 20. Which characteristic describes the default gateway of a host computer?
Explain:The default gateway is the IP address of an interface on the router on the same network as the sending host. 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:The EIA is an international standards and trade organization for electronics organizations. It is best known for its standards related to electrical wiring, connectors, and the 19-inch racks used to mount networking equipment. 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 Other Quetions24. 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?
Explanation: When a PC wants to send data on the network, it always knows the IP address of the destination. However, it also needs to discover the MAC address of the destination. ARP is the protocol that is used to discover the MAC address of a host that belongs to the same network. 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? Explanation: TCP provides reliable delivery of data. UDP provides unreliable delivery of data. DHCP is used for the automatic assignment of IP addresses. ARP is used to discover the MAC address of a device on the 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?
Explanation: A frame is encapsulated with source and destination MAC addresses. The source device will not know the MAC address of the remote host. An ARP request will be sent by the source and will be responded to by the router. The router will respond with the MAC address of its interface, the one which is connected to the same network as the source. 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?
What characteristic of electricity is expressed in watts?
Explanation: Watts is the unit used to measure the electrical power. Power refers to the work required to move electrons through a circuit multiplied by the number of electrons flowing through a circuit per second. [sociallocker id=”54558″] [/sociallocker] |
