HOTSPOT You need to recommend which inbound ports to the network and outbound ports to Office 365 must be allowed on the company’s firewall after the planned upgrade. The solution must meet the security requirements. Which inbound and outbound ports should you recommend? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. 
I don’t think you should recommend any inbound ports for Teams cloud-just outbound 80 (HTTP) and 443 (HTTPS). Inbound is only needed on-prem or when you're running local services, which isn’t the case here. The question trips people up with those inbound distractors. Pretty sure outbound 80/443 is all you need for Office 365 connectivity. Let me know if I’m missing something.
I don’t think it needs inbound ports at all for Teams cloud, just outbound 80 and 443. Common mistake to allow unnecessary inbound traffic here from exam reports. Outbound only.
