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
the IP address of the destination host
the MAC address of the destination host
the IP address of the default gateway
3.
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
avoiding possible incompatibility issues by using a common set of developing tools
enhancing network transmission performance by defining targets for each layer
simplifying protocol development by limiting every layer to one function
4.

flow control
encapsulation
access method
response timeout
5.
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?

broadcast
HTTP
multicast
unicast
ARP
10.
What is a function of Layer 4 of the OSI model?
to represent data to the user, including encoding and dialog control
to specify the packet type to be used by the communications
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
11.
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.
12.
Which IEEE standard enables a wireless NIC to connect to a wireless AP that is made by a different manufacturer?
802.11
802.1
802.3
802.2
13.
If the default gateway is configured incorrectly on the host, what is the impact on communications?
The host is unable to communicate on the local network.
There is no 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.
14.
What statement describes the function of the Address Resolution Protocol?
ARP is used to discover the IP address of any host on the local network.
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 a different network.
ARP is used to discover the MAC address of any host on the local network.
15.
At which layer of the OSI model would a logical address be encapsulated?
transport layer
physical layer
network layer
data link layer
16.
What is the general term that is used to describe a piece of data at any layer of a networking model?
protocol data unit
segment
frame
packet
17.
Which statement is true about the TCP/IP and OSI models?
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.
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.
18.
Which address provides a unique host address for data communications at the internet layer?
Layer 2 address
data-link address
physical address
logical address
19.

ARP
TCP
20.
Which address does a NIC use when deciding whether to accept a frame?
source MAC address
destination MAC address
source Ethernet address
destination IP address
source IP address
21.

22.
What are proprietary protocols?
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
