Network engineers are more concerned with which layer?
Correct answer: C. middle layer
- A. lower layer
- B. upper layer
- C. middle layer
- D. network layer
Explanation
The middle layer, specifically the network layer (layer 3) of the OSI model, is the primary area of focus for network engineers. This layer is responsible for routing data packets across networks. Network engineers design, configure, and maintain the devices that operate at this layer, such as routers and switches. They are also responsible for ensuring that networks are efficient and reliable.
