What three application layer protocols are part of the TCP/IP protocol suite? (Choose three.)
DHCP DNS FTP
Which statement is true about the TCP/IP and OSI models?
The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.
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? (https://ccnav6.com/wp-content/uploads/2017/05/p15-exa3-ccna2.png)
The VLAN that is used by PC-A is not in the list of allowed VLANs on the trunk.
If the default gateway is configured incorrectly on the host, what is the impact on communications?
The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks.
Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model? (Choose three.)
application presentation session
Refer to the exhibit. If Host1 were to transfer a file to the server, what layers of the TCP/IP model would be used? (https://ccnav6.com/wp-content/uploads/2017/05/i275370v1n1_275370.jpg)
application, transport, Internet, and network access layers
What type of communication will send a message to all devices on a local area network?
broadcast
Which address does a NIC use when deciding whether to accept a frame?
destination MAC address
What process is used to place one message inside another message for transfer from the source to the destination?
encapsulation
What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?
flow control
What is a benefit of using a layered model for network communications?
fostering competition among device and software vendors by enforcing the compatibility of their products
What is the general term that is used to describe a piece of data at any layer of a networking model?
protocol data unit
What are proprietary protocols?
protocols developed by organizations who have control over their definition and operation
Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model?
segment
Which IEEE standard enables a wireless NIC to connect to a wireless AP that is made by a different manufacturer?
802.11
What is an advantage of network devices using open standard protocols
A client host and a server running different operating systems can successfully exchange data.
Which statement is correct about network protocols?
They define how messages are exchanged between the source and the destination.
Which address provides a unique host address for data communications at the internet layer?
logical address
A computer in a given network is communicating with a specific group of computers. What type of communication is this?
multicast
At which layer of the OSI model would a logical address be encapsulated
network layer
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?
the MAC address of the default gateway
What is a function of Layer 4 of the OSI model?
to describe the ordered and reliable delivery of data between source and destination
Match each description to its corresponding term. (Not all options are used.) (https://ccnav6.com/wp-content/uploads/2017/05/2017-05-23_190456.png)

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.) (https://ccnav6.com/wp-content/uploads/2017/05/i214638v1n1_214638.jpg)
A packet with the destination IP address of RouterB. A frame with the destination MAC address of RouterA.
Which protocol is used by a computer to find the MAC address of the default gateway on an Ethernet network?
ARP
What statement describes the function of the Address Resolution Protocol?
ARP is used to discover the MAC address of any host on the local network.
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?
HTTP, TCP, IP, Ethernet
What is an advantage of using standards to develop and implement protocols?
Products from different manufacturers can interoperate successfully.
Which protocol is responsible for controlling the size and rate of the HTTP messages exchanged between server and client?
TCP
Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?
Segments are sent from the transport layer to the internet layer.
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?
TCP
What will happen if the default gateway address is incorrectly configured on a host?
The host cannot communicate with hosts in other networks.
Which PDU format is used when bits are received from the network medium by the NIC of a host?
frame
Which command is used to remove only VLAN 20 from a switch?
no vlan 20
Which characteristic describes the default gateway of a host computer?
the logical address of the router interface on the same network as the host computer
