Question 1 of 14
1. Question
1 pointsWhich TCP/IP model layer is closest to the end user?Correct
Incorrect
End users use applications to interact with and use the network. The application layer of the TCP/IP model is closest to the end user. Application layer protocols are used to communicate and exchange messages with other network devices and applications. The layers of the TCP/IP model are from top to bottom (memory aid – ATIN): application, transport, internet, network access

2. Question
1 pointsWhat is an advantage of SMB over FTP?Correct
Incorrect
SMB and FTP are client/server protocols that are used for file transfer. SMB allows the connecting device to access resources as if they were on the local client device. SMB and FTP use the TCP protocol for connection establishment and they can transfer data in both directions. FTP requires two connections between the client and the server, one for commands and replies, the other for the actual file transfer.

4. Question
2 pointsWhich three protocols or standards are used at the application layer of the TCP/IP model? (Choose three.)Correct
Incorrect
HTTP, MPEG, and GIF operate at the application layer of the TCP/IP model. TCP and UDP operate at the transport layer. IP operates at the internet layer.

5. Question
1 pointsTrue or False?
In FTP transactions, an FTP client uses the pull method to download files from an FTP server.
Correct
Incorrect
The File Transfer Protocol (FTP) is a commonly used application layer protocol. FTP allows for data transfers between a client and a server. During data transfers, the FTP client downloads (pulls) data from the server. The FTP client can also upload (push) data to the server.

Question 6 of 14
6. Question
1 pointsOn a home network, which device is most likely to provide dynamic IP addressing to clients on the home network?Correct
Incorrect
On a home network, a home router usually serves as the DHCP server. The home router is responsible for dynamically assigning IP addresses to clients on the home network. ISPs also use DHCP, but it usually assigns an IP address to the Internet interface of the home router, not the clients on the home network. In businesses, it is common to have a file or other dedicated server provide DHCP services to the network. Finally, a DNS server is responsible for finding the IP address for a URL, not for providing dynamic addressing to network clients.

7. Question
1 pointsWhat is a common protocol that is used with peer-to-peer applications such as WireShare, Bearshare, and Shareaza?Correct
Incorrect
The Gnutella protocol is used when one user shares an entire file with another user. A person would load a Gnutella-based application such as gtk-gnutella or WireShare and use that application to locate and access resources shared by others.

Question 8 of 14
8. Question
1 pointsWhat is true about a client-server network?Correct
Incorrect
In a client-server network, a dedicated server responds to service requests from clients. The roles of client and server are not shared on each host in the network. In a peer-to-peer network, computers are connected via a network and can share resources. Each host can function as a server or a client based on the nature of the transaction and what resources are used or requested. A hybrid network is one in which a server supplies index information that enables a peer to locate resources on other peers. In this case the peers can still have the role of client or server depending on the nature of the network transaction.

9. Question
1 pointsWhich protocol can be used to transfer messages from an email server to an email client?Correct
Incorrect
SMTP is used to send mail from the client to the server but POP3 is used to download mail from the server to the client. HTTP and SNMP are protocols that are unrelated to email.

10. Question
1 pointsA wired laser printer is attached to a home computer. That printer has been shared so that other computers on the home network can also use the printer. What networking model is in use?Correct
Incorrect
Peer-to-peer (P2P) networks have two or more network devices that can share resources such as printers or files without having a dedicated server.

11. Question
3 pointsWhich three layers of the OSI model provide similar network services to those provided by the application layer of the TCP/IP model? (Choose three.)Correct
Incorrect
The three upper layers of the OSI model, the session, presentation, and application layers, provide application services similar to those provided by the TCP/IP model application layer. Lower layers of the OSI model are more concerned with data flow.

12. Question
2 pointsA user is attempting to access http://www.cisco.com/ without success. Which two configuration values must be set on the host to allow this access? (Choose two.)Correct
Incorrect
In order to use a URL such as http://www.cisco.com, the DNS protocol must be used in order to translate the URL into an IP address. Furthermore, the host device requesting this web page must have a default gateway configured in order to communicate with remote networks.

13. Question
1 pointsWhy is DHCP preferred for use on large networks?Correct
Incorrect
Static IP address assignment requires personnel to configure each network host with addresses manually. Large networks can change frequently and have many more hosts to configure than do small networks. DHCP provides a much more efficient means of configuring and managing IP addresses on large networks than does static address assignment.

14. Question
1 pointsWhich command is used to manually query a DNS server to resolve a specific host name?Correct
Incorrect
The nslookup command was created to allow a user to manually query a DNS server to resolve a given host name. The ipconfig /displaydns command only displays previously resolved DNS entries. The tracert command was created to examine the path that packets take as they cross a network and can resolve a hostname by automatically querying a DNS server. The ping command was created to test reachability on a network and can resolve a hostname by automatically querying a DNS server.
