> Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?

Frames are sent from the network access layer to the internet layer.

Data is sent from the internet layer to the network access layer.

Segments are sent from the transport layer to the internet layer.

Packets are sent from the network access layer to the transport layer.

> A computer in a given network is communicating with a specific group of computers. What type of communication is this?

Unicast

Multicast

HTTP

ARP

Broadcast

> 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.

The host can communicate with other hosts on remote networks, but is unable to communicate with hosts on the local network.
There is no impact on communications.

The host is unable to communicate on the local network.

> Which address provides a unique host address for data communications at the internet layer?

Physical address

Data-link address

Logical address

Layer 2 address

> Match the description to the organization.

> Which IEEE standard enables a wireless NIC to connect to a wireless AP that is made by a different manufacturer?

802.2

802.3

802.1

802.11

> 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?

10.1.1.1

172.16.1.1

192.168.1.1

192.168.1.10

192.168.1.2

> What is a benefit of using a layered model for network communications?

Simplifying protocol development by limiting every layer to one function

Avoiding possible incompatibility issues by using a common set of developing tools
Fostering competition among device and software vendors by enforcing the compatibility of their products
Enhancing Network transmission performance by defining targets for each layer

> Which protocol is responsible for controlling the size and rate of the HTTP messages exchanged between server and client?

DHCP

TCP

HTTP

ARP

> At which layer of the OSI model would a logical address be encapsulated?

Data link layer

Physical layer

Transport layer

Network layer

> What is a function of Layer 4 of the OSI model?

To describe the ordered and reliable delivery of data between source and destination

To apply framing information to the packet, based on the attached media

To specify the packet type to be used by the communications

To represent data to the user, including encoding and dialog control

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

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.

> What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?

Response timeout

Encapsulation

Flow control

Access method

> What statement describes the function of the Address Resolution Protocol?

ARP is used to discover the IP address of any host on a different network.

ARP is used to discover the MAC address of any host on the local network.

ARP is used to discover the IP address of any host on the local network.

ARP is used to discover the MAC address of any host on a different network.

> 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 destination host

The IP address of the destination host

The MAC address of the default gateway

The IP address of the default gateway

> Which address does a NIC use when deciding whether to accept a frame?

Source IP address

Destination IP address

Source Ethernet address

Destination MAC address

Source MAC address

> What is an advantage of network devices using open standard protocols?

Network communications is confined to data transfers between devices from the same vendor.

Competition and innovation are limited to specific types of products.

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.

> What are proprietary protocols?

A collection of protocols known as the TCP/IP protocol suite

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

Protocols developed by private organizations to operate on any vendor hardware

Protocols that can be freely used by any organization or vendor

> 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, IP, TCP, Ethernet

Ethernet, TCP, IP, HTTP

HTTP, TCP, IP, Ethernet

Ethernet, IP, TCP, HTTP

TCP

ARP

HTTP

DHCP

> What is the general term that is used to describe a piece of data at any layer of a networking model?

Segment

Packet

Frame

> Which PDU format is used when bits are received from the network medium by the NIC of a host?

Frame

Segment
