Sh mac-address-table on switches in packet tracer only shows the trunk ports?

Regarding the VTP lab sim, i typed sh mac-address-table on l2 switch. But it made an output only showing trunk ports whereas according to the question it has to show all ports. why not?

edit : do not get me wrong. this command can output neighbor's ports once learned but on that sim, it showed and output which consists of ports belong to neighbors without interacting the workstations, how could this be?

    Till the host don't send any data on the network, the switch can't learn the mac addresses.
    Did you checked the static addresses in the running config? :)

    Wait! i have already said that on my edit. However, the sim requires from me to answer the questions from the perspective of SW-Ac3. When i type sh mac-address-table, i only see trunk ports and their mac addresses on this switch. But, i need to
    catch the "learned" mac addresses by that switch. Since PCs are not assigned any IP addresses, i can not seem to
    examine the "learned" mac addresses.

    sh vlan doesn't help. sh mac-address-table shows only that Switch's trunk ports connected to other switches and router. Would you tell me how you see fa 0/8 for the question 1?

    That mac address is associated with one of the switch's port. You can find the answer in the running config.
