The application layer is the highest layer (layer 7) of the OSI model, and is reserved for end user applications. Since FTP is itself an application, layer 7 is the highest layer used.

Incorrect Answers:
B, C, D, E, F, G. In any given FTP session, all of these layers will be used at some point but they are incorrect because the question asked for the highest layer used by FTP.

第9题：

You configure your Windows 2000 Professional computer for Internet Connection Sharing and for TCP/IP filtering as shown in the exhibit.

You test your TCP/IP filtering configuration from another client computer. You can access web sites, but you cannot access FTP sites.

What should you do to be able to access FTP sites?

A．Add Port 21 to the TCP Ports section.

B．Add Port 138 to the TCP Ports section.

C．Add Port 21 to the IP Ports section.

D．Add Port 138 to the IP Ports section.


正确答案：A
解析：Explanation: The FTP protocol uses the TCP port 21. In the exhibit the UDP port 21 has been incorrectly added instead of the TCP port.

Incorrect answers:
B: The FTP protocol uses Port 21 not Port 138.

C: The port 21 should be added as a TCP port 21, not as a UDP port or as an IP protocol. IP is also a network protocol and not a port.

D: The FTP protocol uses TCP port 21 not port 138. IP is also a network protocol and not a port.

第10题：

The File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer （ ） between a client and server on a computer network.FTP is built on a （请作答此空） model architecture using separate control and data connections between the client and the server. FTP users may authenticate themselves with a （ ） sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS (FTPS) or replaced with SSH File Transfer Protocol (SFTP).The first FTP client applications were （ ） programs developed before operating systems had graphical user interfaces, and are still shipped with most Windows, Unix, and Linux operating systems. Many FTP clients and automation utilities have since been developed for desktops, servers, mobile devices, and hardware, and FTP has been incorporated into productivity applications, such as HTML editors.FTP may run in （ ） mode, which determines how the data connection is established. In both cases, the client creates a TCP control connection from a random, usually an unprivileged, port N to the FTP server command port 21.In active mode, the client starts listening for incoming data connections from the server on port M. It sends the FTP command PORT M to inform the server on which port it is listening. The server then initiates a data channel to the client from its port 20, the FTP server data port.In situations where the client is behind a firewall and unable to accept incoming TCP connections, passive mode may be used. In this mode, the client uses the control connection to send a PASV command to the server and then receives a server IP address and server port number from the server, which the client then uses to open a data connection from an arbitrary client port to the server IP address and server port number received.Both modes were updated in September 1998 to support IPv6. Further changes were introduced to the passive mode at that time, updating it to extended passive mode.

A.browser-server
B.user- server
C.client-server
D.business -customer

The File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer files between a client and server on a computer network.FTP is built on a client-server model architecture using separate control and data connections between the client and the server.
