config help with Vlans

Good day all.

I need some help im new to mikrotik and testing it a bit.

My goal is to put up 3 Aps with trunk or tagged ports to have a management network and Data with the 4th port with same config to comunicate back to the main site.

I know in the past you could set all the interfaces as slaves with new firmware im lost.

A. RB750ip —> Trunk —> B. RB750 up

Unit be must have all the ports in the same trunk.

Please assist
