Which component displays the second level of DMR displays?

• A. ITU
• B. Ethernet hub
• C. ITUs
• D. DMR network level

Answer: (C)

Understanding how DMR displays are organized helps you see why the second-level displays are ITUs. In a DMR system, information is shown in layered views. The top level presents the overall DMR network view, giving a broad snapshot of the network as a whole. The second level is represented by ITUs, which provide the mid-level context and grouping within the DMR structure. The bottom layer would include individual radios or terminals, which aren’t the focus here. An Ethernet hub is simply a network device, not a DMR display level, and a single ITU would describe just one unit rather than the collective mid-level display context. So, ITUs is the component that corresponds to the second level of DMR displays.
