A manager wants to distribute a report to several other managers within the company. Some of them reside in remote locations that are not connected to the domain but have a local server. Because…

S/MIME (Secure/Multipurpose Internet Mail Extensions) is specifically designed to encrypt and sign email messages, which is not a viable option here since emailing the report is explicitly ruled out due to attachment size limits.

SSH (Secure Shell) provides an encrypted channel for secure remote file transfer via SCP or SFTP, making it ideal for transferring sensitive files to remote servers not connected to the domain, as it requires no domain infrastructure and encrypts data in transit.

SNMPv3 (Simple Network Management Protocol version 3) is a network device monitoring and management protocol, not a file transfer protocol, so it cannot be used to distribute reports.

FTPS (FTP Secure) is an extension of FTP that adds TLS/SSL encryption, enabling secure file transfers of large files to remote local servers without email size restrictions, making it appropriate for distributing sensitive reports over untrusted networks.

SRTP (Secure Real-time Transport Protocol) is designed to encrypt real-time audio and video streaming data, not for file distribution or transfer of documents.

HTTPS (HTTP Secure) uses TLS/SSL to encrypt web-based file transfers, allowing managers at remote locations to securely download or upload large reports through a web interface without requiring domain membership or email.

LDAPS (Lightweight Directory Access Protocol Secure) is used for secure directory service queries and authentication against domain controllers, not for file transfer, and would be irrelevant to remote locations not connected to the domain.
