A cloud administrator set up a link between the private and public cloud through a VPN tunnel. As part of the migration, a large set of files will be copied. Which of the following network ports are required from a security perspective?
Answer(s): B
Given the VPN is taking care of the secure part of the equation, I guess you could technically get away with "D", but NetBIOS is deprecated. SFTP is better suited for moving large files compared to SMB. There's no mention of overhead concern here so securely transferring your files (SFTP) over a secure connection (VPN) isn't something I would see as being problematic (can never be too secure). SMB may need to rely on NetBios to communicate, but ONLY if the device in question is old and is unable to support direct hosting of SMB over TCP/IP.
