When users map a drive to a file share, they use the Server Message Block (SMB) protocol over TCP port 445. Therefore, you need to open outbound port 445 on the home computers to allow access to the file share in the Azure Storage account.
Here's a brief overview of the other options and why they're not the correct choice:
A. Port 80 is used for HTTP traffic, not SMB.
B. Port 443 is used for HTTPS traffic, not SMB.
C. Port 445 is the correct choice, as mentioned above.
D. Port 3389 is used for Remote Desktop Protocol (RDP), not SMB.
Therefore, the correct answer is C. 445.
