 - The question should not be written all capitalized and in fact also not be needed. Because the network manager is supposed to know what he is doing when he assigns subnet-ranges to vlans (e.g.). These ranges can usually be found by examining the vlan assigned interface-address in the running configuration of master (switches) in the network where the accompanying subnet  mask is then also defined (e.g.)
