  • flow control
  • access method
  • response timeout

Pregunta 2

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

Pregunta 3

Pregunta

Respuesta
  • access control
  • decoding
  • encapsulation
  • flow control

Pregunta 4

Pregunta
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?
Respuesta
  • HTTP, IP, TCP, Ethernet
  • HTTP, TCP, IP, Ethernet
  • Ethernet, TCP, IP, HTTP
  • Ethernet, IP, TCP, HTTP

Pregunta 5

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

Pregunta 6

Pregunta
Which statement is true about the TCP/IP and OSI models?
Respuesta
  • The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.
  • 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 first three OSI layers describe general services that are also provided by the TCP/IP internet layer.​

Pregunta 7

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

Pregunta 8

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

Pregunta 9

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

Pregunta 10

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

Pregunta 11

Pregunta
Refer to the exhibit. If Host1 were to transfer a file to the server, what layers of the TCP/IP model would be used?
Image:

Respuesta
  • only application and Internet layers
  • only Internet and network access layers
  • only application, Internet, and network access layers
  • application, transport, Internet, and network access layers
  • only application, transport, network, data link, and physical layers
  • application, session, transport, network, data link, and physical layers

Pregunta 12

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

Pregunta 13

Pregunta
At which layer of the OSI model would a logical address be encapsulated?
Respuesta
  • physical layer
  • data link layer
  • network layer
  • transport layer

Pregunta 14

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

Pregunta 15

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

Pregunta 16

Pregunta
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.)
Image:
641b86cc-e830-4bd5-9e68-12ce24bda05b (image/png)
Respuesta
  • A packet with the destination IP address of RouterB.
  • A frame with the destination MAC address of SwitchA.
  • A packet with the destination IP address of RouterA.
  • A frame with the destination IP address of RouterA.
  • A frame with the destination MAC address of RouterA.
  • A packet with the destination IP address of ServerB.
  • A frame with the destination MAC address of ServerB.

Pregunta 17

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

Pregunta 18

Pregunta
What will happen if the default gateway address is incorrectly configured on a host?
Respuesta
  • 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.

Pregunta 19

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