Multiple vAP in own VLANs with Windows DHCP

Hi.
I have need of little bit of help for this scenario, where I’m trying to combine CISCO with Mikrotik.
I have network divided in to several VLANs, for example VLAN 100, 101 and 102, for every floor separately. All the computers are connected to access switches CISCO Catalyst 2960X and the main switch is Layer 3 Catalyst 3850. This is a core switch and is making whole the routing, although, there is no VLAN filtering between, yet.
All VLAN are using Windows DHCP server, positioned in server’s VLAN10.
I have created 3 additional VLANs (VLAN103, VLAN104 and VLAN105) for wireless users, which should be connected via Microtik AP.
In this moment, I have only one RB951, for testing purposes, but if this works, I have plan to buy several, let’s say RouterBOARD cAP-2nD and put them on every floor.
My plan is to create, for starters, 3 SSID (VAP) for each VLAN, for ex:

SSID=sales, VLAN103,
SSID=accounting, VLAN104,
SSID=guest, VLAN105.
and so on…

VLAN105 should be isolated completely from the rest of the network.

What should I do?

I connected the RB951, one of the access switches, on a port, configured as a TRUNK.
The DHCP server is configured and ready. It’s the same Windows Server in VLAN10.

P.S.
I know, for scenario with multiple access points, I should use CAPsMAN configuration, but for now I want to try with one AP.

Regards,
