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 fundsB．It encourages industry standardization by defining what functions occur at each layer of the modelC．It divides the network communication process into smaller and simpler components; thus aiding component development, design and troubleshootingD．It provides a means by which changes in functionality in one layer require changes in other layersE．It supports the evolution of multiple competing standards and thus provides business opportunities for equipment manufacturers
