Answer
(a) The cable layout for these compounds is given below:
Main compound - Resource compound - Training compound - Finance compound
(b)
(i) A repeater should be placed between the Resource Compound and the Finance Compound due to the 135-meter distance, as it is used to regenerate and amplify signals to cover longer distances without losing quality.
(ii) A hub or switch connects multiple devices within a compound, allowing them to communicate with each other and the broader network. So, there should be one hub per compound.
