Flex Connect Provisioning Scenario

Dear Folks,

As I have did installation of WLC's before, it is my first time to do flex connect scenario. Based on the scenario, kindly advise, if I assume correctly the logic related with Flex Connect . Consider I have a HQ site with WLC installed and objective is to have AP's installed in local and in a remote site. Basic tests has passed, as both networks can see each other.
Now Details as follows
HQ WLC :
Vlan 100 - AP - Management (DHCP in Core Switch itself local)
Vlan 101 - AP - EMP (DHCP in DHCP Server)
Vlan 102 - AP - Guest (DHCP in DHCP Server)

Remote Site :
 Vlan 200 - AP - Management (DHCP in local switch)
Vlan 201 - AP - EMP (DHCP in local switch )
Vlan 202 - AP - Guest (DHCP in local switch )

Questions are as follows :
1. AP's in HQ can be directly provisioned using local mode as controller is in the same area  . No need to change to flex connect ,right ?
2. Once Controller is up, can we provision AP directly in remote site for flex connect, or should we provision it in HQ and then transfer to remote site. The reason for this question is , AP's were already mounted and if need to be provisioned, needs to be taken out for the ceiling.  
3. If there is controller dedicated for Guest Access in DMZ, does it require any AP license or basic license is just required ?


Please advise .

Thanks ,
SID

Correct.
2. Once Controller is up, can we provision AP directly in remote site for flex connect, or should we provision it in HQ and then transfer to remote site. The reason for this question is , AP's were already mounted and if need to be provisioned, needs to be taken out for the ceiling.  
Send the APs to site.  Before they go you can prime them (configure them with the WLC IP) if you want but it's not mandatory as long as DHCP option 43 is configured at the remote site for the scope.  They will connect to the WLC as long as they can connect to its management IP.  Once they join just change the AP's mode to FlexConnect.  This is actually a common deployment scenario.  (If you configure them at HQ your VLAN IDs are different so they might not work when they get to the site they need to be at!)
3. If there is controller dedicated for Guest Access in DMZ, does it require any AP license or basic license is just required ?
Buy a controller with the least available number of APs.  If you have a 5508 as the Guest Anchor, buy the AIR-CT5508-12-K9.  If you have a 2504 buy the AIR-CT2504-5-K9.  No APs will directly join this WLC so it's not a problem.
