Netacad CCNA Chapter 3 Exam

7 What is an advantage of network devices using open standard protocols? Competition and innovation are limited to specific types of products. A client host and a server running different operating systems can successfully exchange data. Network communications is confined to data transfers between devices from the same vendor. Internet access can be controlled by a single ISP in each market.

A client host and a server running different operating systems can successfully exchange data.

3 What three application layer protocols are part of the TCP/IP protocol suite? (Choose three.) NAT DNS ARP DHCP FTP PPP

DNS DHCP FTP

21 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? Ethernet, TCP, IP, HTTP HTTP, TCP, IP, Ethernet HTTP, IP, TCP, Ethernet Ethernet, IP, TCP, HTTP

HTTP, TCP, IP, Ethernet

17 Refer to the exhibit. If Host1 were to transfer a file to the server, what layers of the TCP/IP model would be used? only application, transport, network, data link, and physical layers only Internet and network access layers only application and Internet layers application, session, transport, network, data link, and physical layers application, transport, Internet, and network access layers only application, Internet, and network access layers

application, transport, Internet, and network access layers

20 What type of communication will send a message to all devices on a local area network? unicast multicast broadcast allcast

broadcast

14 Which PDU format is used when bits are received from the network medium by the NIC of a host? file segment frame packet

frame

13 At which layer of the OSI model would a logical address be added during encapsulation? network layer physical layer transport layer data link layer

network layer

6 What are proprietary protocols? protocols developed by private organizations to operate on any vendor hardware a collection of protocols known as the TCP/IP protocol suite protocols developed by organizations who have control over their definition and operation protocols that can be freely used by any organization or vendor

protocols developed by organizations who have control over their definition and operation

10 Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model? segment bits packet frame

segment

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.) preparing packets to be transmitted over the network media managing the individual conversations between web servers and web clients governing the way a web server and a web client interact taking the segments from the transport protocol, encapsulating them into packets, and assigning them with appropriate addresses With application protocol internet protocol network access protocol network time protocol transport protocol

transport protocol managing the individual conversations between web servers and web clients internet protocol taking the segments from the transport protocol, encapsulating them into packets, and assigning them with appropriate addresses message encapsulation governing the way a web server and a web client interact network time protocol (is used to synchronize clocks between computer systems. It is not involved in this case.) N/A network access protocol preparing packets to be transmitted over the network media

16 What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly? access method response timeout flow control encapsulation

flow control

18 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.) A frame with the destination MAC address of RouterA. A packet with the destination IP address of RouterA. A frame with the destination MAC address of ServerB. A frame with the destination MAC address of SwitchA. A packet with the destination IP address of RouterB. A packet with the destination IP address of ServerB.

A frame with the destination MAC address of RouterA. A packet with the destination IP address of ServerB.In order to send data to ServerB, HostA will generate a packet that contains the IP address of the destination device on the remote network and a frame that contains the MAC address of the default gateway device on the local network.

4 Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model? (Choose three.) network session application data link presentation transport physical

Application Presentation Session

22 What is an advantage of using standards to develop and implement protocols? Products from different manufacturers can interoperate successfully. Standards provide flexibility for manufacturers to create devices that comply with unique requirements. Different manufacturers are free to apply different requirements when implementing a protocol. A particular protocol can only be implemented by one manufacturer.

Products from different manufacturers can interoperate successfully.

19 Which statement is true about the TCP/IP and OSI models?​ The TCP/IP network access layer has similar functions to the OSI network layer.​ The OSI Layer 7 and the TCP/IP application layer provide identical functions. The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.​ The first three OSI layers describe general services that are also provided by the TCP/IP internet layer.​

The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.​

15 What will happen if the default gateway address is incorrectly configured on a host? The host cannot communicate with other hosts in the local network. The switch will not forward packets initiated by the host. The host will have to use ARP to determine the correct address of the default gateway. The host cannot communicate with hosts in other networks. A ping from the host to 127.0.0.1 would not be successful.

The host cannot communicate with hosts in other networks.

5 Which statement is correct about network protocols? Network protocols define the type of hardware that is used and how it is mounted in racks. They all function in the network access layer of TCP/IP. They define how messages are exchanged between the source and the destination. They are only required for exchange of messages between devices on remote networks.

They define how messages are exchanged between the source and the destination.

Match the description to the organization. (Not all options are used.) This organization is responsible for overseeing and managing IP address allocation, domain name management, and protocol identifiers. This organization is the largest developer of international standards in the world for a wide variety of products and services. It is known for its Open Systems Interconnection (OSI) reference model. This organization promotes the open development, evolution, and use of the Internet throughout the world. WITH ISOC ISO EIA IANA

2 Which address does a NIC use when deciding whether to accept a frame? source IP address source MAC address source Ethernet address destination MAC address destination IP address

destination MAC address

9 What process is used to place one message inside another message for transfer from the source to the destination? access control flow control encapsulation decoding

encapsulation

12 Which characteristic describes the default gateway of a host computer? the logical address assigned to the switch interface connected to the router the physical address of the router interface on the same network as the host computer the physical address of the switch interface connected to the host computer the logical address of the router interface on the same network as the host computer

the logical address of the router interface on the same network as the host computer. (The default gateway is the IP address of an interface on the router on the same network as the sending host.)
