Question 66General Subjects - Assistant Engineer

The correct answer is B. The explanation is as follows: 1) The statement is true that the LAN is a dual redundant network and the partitioned CAN is also a dual redundant network, with both networks being interconnected. 2) This is correct because the block diagram illustrates a distributed automation system with two separate area networks - a dual redundant LAN and a dual redundant partitioned CAN - that are interconnected, allowing communication between the two networks. 3) The other options are incorrect because they do not accurately describe the interconnectivity between the two redundant networks as shown in the diagram. 4) In summary, the key aspects that make option B the correct answer are the dual redundancy of both networks and the interconnectivity between them, as depicted in the illustrated block diagram.
