As part of a network upgrade project, your task is to document the existing network infrastructure so it can be used for future expansions and troubleshooting. Which type of network diagram would be most beneficial because it shows both the physical elements and their logical interconnections?
Creating a diagram that combines physical and logical views offers a complete picture of the network. The physical portion shows tangible details such as device locations, cable runs, and rack layouts, while the logical portion illustrates IP addressing, VLANs, and traffic flow. Having both perspectives in a single diagram (or paired companion diagrams) streamlines troubleshooting and makes it easier to predict how changes to one layer will affect overall connectivity.
