第3题：
As the Ezonexam network administrator, you are required to have a firm understanding of the OSI model. Why does the data communication industry use the layered OSI reference model? (Choose two)
A．It enables equipment from different vendors to use the same electronic components, thus saving research and development funds
B．It encourages industry standardization by defining what functions occur at each layer of the model
C．It divides the network communication process into smaller and simpler components; thus aiding component development, design and troubleshooting
D．It provides a means by which changes in functionality in one layer require changes in other layers
E．It supports the evolution of multiple competing standards and thus provides business opportunities for equipment manufacturers
解析：Explanation:
The OSI (Open System Interconnection) reference model was created as a reference point for communications devices. A layered approach is used to segment the entire telecommunications process into a series of smaller steps.
A is correct because it encourages a level of standardization by encouraging that functions be compared to known layers.
D is also correct because it allows engineers to focus on the development, refining, and perfection of simpler components.

Which layer of the OSI reference model is responsible for ensuring reliable end-to-end delivery of data?
A. Application
B. Presentation
C. Session
D. Transport
E. Network
F. Data-Link
D 解析：Explanation:
A key function of the transport layer is to provide connection services for the protocols and applications that run at the levels above it. These can be categorized as either connection-oriented services or connectionless services. Some protocol suites, such as TCP/IP, provide both a connection-oriented and a connectionless transport layer protocol, to suit the needs of different applications.
The transport layer is also the place in the layer stack where functions are normally included to add features to end-to-end data transport. Where network layer protocols are normally concerned with just "best effort" communications, where delivery is not guaranteed. Transport layer protocols are given intelligence in the form. of algorithms that ensure that reliable and efficient communication between devices takes place. This encompasses several related jobs, including lost transmission detection and handling, and managing the rate at which data is sent to ensure that the receiving device is not overwhelmed.
Transmission quality, meaning ensuring that transmissions are received as sent, is so important that some networking references define the transport layer on the basis of reliability and flow-control functions. However, not all transport layer protocols provide these services. Just as a protocol suite may have a connection-oriented and a connectionless transport layer protocol, it may also have one that provides reliability and data management services, and one that does not. Again, this is the case with TCP/IP: there is one main transport layer protocol; TCP, that includes reliability and flow control features, and a second, UDP, that doesn't.
