第十一章

1、End systems use port numbers to select the proper application. What is the smallest port number that can be dynamically assigned by a host system?

终端系统使用端口号来选择合适的应用程序。主机系统可以动态分配的最小端口号是什么？
A.1
B.64
C.128
D.256
E.512
F.1024

端口号个数2^16。1~1024是系统维护分配

在数据传输期间，接收主机的主要职责是什么？(选择两个)
A.throughput 吞吐量
B.encapsulation封装
C.acknowledgment确认
D.bandwidth带宽
E.segmentation分段
F.reassembly重组

3、TCPIP connection-oriented sessions begin with a three-way handshake.Which items describe the handshake process?(Choose three.,)[多选]

面向TCP连接的会话以三方握手开始。哪些项目描述握手过程？(选择三.，)[多选]
A.acknowledge确认
B.synchronize同步
C.encapsulate封装
D.negotiate谈判
E.create创造
F.propagate宣传

4、What is the purpose of TCP/UDP port numbers?

TCP/UDP端口号的用途是什么？
A.indicate the beginning of a three-way handshake
表示三方握手的开始
B.reassemble the segments into the correct order
B.将分段重新组装成正确的顺序
C.identify the number of data packets that may be sent without acknowledgment
C.确定可能在没有确认的情况下发送的数据包数量
D.track different conversations crossing the network at the same time
同时跟踪跨网络的不同对话

5、Which of the following describes the operation of TCP window size?

下面哪个描述TCP窗口大小的操作？

A.Window size increases as all data transfers.
随着所有数据的传输，窗口大小增加。
Window size is the TCP process used prepare data for transmission
窗口大小是TCP进程，用于传输的准备数据。
C.window size is decreased if packets are lost.
如果数据包丢失，窗口大小会减小。
D.Window size of 15 means that the next byte expected is byte number 15.
窗口大小为15意味着下一个字节是字节号15。

6、Which of the following protocols operate at the application layer of the OSl model?(Choose two.)[多选

以下哪一种协议在OSL模型的应用层操作？(选择两种)[多选
A.FTP
B.TCP
C.UDP
D.HTTP

7、Which of the following services is used to translate a web address into an lP address?Which of the following services is used to translate a web address into an IP address?

以下哪个服务被用来将一个Web地址转换成一个IP地址？
A.DNS
B.WINS
C.DHCP
D.Telnet

8、Which protocols can be used to transfer files between systems?(Choose two)

哪些协议可用于在系统之间传输文件？(选择两个)
A.TFTP
B.DNS
C.SNMP
D.FTP
E.DHCP

9、What does TCP use to begin the three-way handshaking process?

TCP用来开始三方握手过程的是什么？
A.The destination host sends an ACK segment.
目标主机发送一个ACK段。
B.The sending host sends a SYN segment.
发送主机发送一个SYN段。
C.The sending host sends a SYN and ACK segment.
发送主机发送SYN和ACK段。
D.The destination host sends a SYN segment.
目标主机发送一个SYN段。
