Chapter 3 Test

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

192.168.1.1

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

802.11

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 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

An IP address, and port

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

Assisting in protocol design because protocols that operate at a specific layer have defined information that they act upon and a defined interface to the layers above and below. ( Fostering competition because products from different vendors can work together. Preventing technology or capability changes in one layer from affecting other layers above and below. Providing a common language to describe networking functions and capabilities.

What type of communication will send a message to all devices on a local area network

Broadcast

What three application layer protocols are part of the TCP/IP protocol suite? (Choose three

DHCP DNS FTP

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

Destination MAC address

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

Frame. Frame is used to receive bits from the network medium by the NIC of a host becase the NIC filters the different frames show random messages don't pop up on the screen.

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

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

What is an advantage of network devices using open standard protocols

Open standards are good because they encourage interoperability, competition, and innovation.

What is an advantage of using standards to develop and implement protocols

Products from different manufacturers can interoperate successfully

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

Protocol data unit

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

Segments go from transport layer, to 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

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

TCP

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

The VLAN that is used by PC-A is not in the list of allowed VLANs on the trunk.

What is a function of Layer 4 of the OSI model

The function of layer 4 is the transport of raw data. Basically, layer 4 can contain different sized boxes of information, and it makes sure that those boxes get to the right destination.

What will happen if the default gateway address is incorrectly configured on a host

The host cannot communicate with hosts in other networks

Which statement is correct about network protocols

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

Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model

application presentation session

. 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 (Flow control is the management of data flow between computers or devices or between nodes in a network so that the data can be handled at an efficient pace)

. Which command is used to remove only VLAN 20 from a switch

no vlan 20

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 mode

segment

If the default gateway is configured incorrectly on the host, what is the impact on communications

the Ethernet data link frame cannot be sent directly to the destination host because the host is not directly reachable in the network of the sender

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
