Ap or SM?

Hello, I am sorry because that cuestion. I am a beginner on Canopy but I would need a very simple explanation from you.

I have seen that you can choose between SM or AP over the same equipment, I am talking about a 5700 or similar. However, I have seen that if you have to buy one, you must choose the correct one, SM or AP where the first one is cheaper than second one.
THERE IS ANY POSSIBILITY THAT AP SUPPORT THAT OPTION? That is to say, AP can be configured as SM but not the oposite. It could be?
Thanks a lot for any response.

If you are asking if the SM can function as an AP the answer is no.

Turn AP to SM is possible
Turn SM to AP is not possible.

Hope it helps.
