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


正确答案：BC
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.
