Comprehensive and Detailed Explanation
To enable file sharing across different operating systems, CompTIA A+ emphasizes the use of:
✔ SMB (Server Message Block)
The primary file-sharing protocol used by Windows.
Also supported on macOS and Linux (via Samba).
Allows shared folders, printers, and network browsing.
✔ FTP (File Transfer Protocol)
A cross-platform file transfer service supported by all major OSs.
Commonly used to upload/download files between systems of different types.
These two protocols are explicitly listed in CompTIA objectives under network protocols and file services.
Why the other options are incorrect
A. NTP – Time synchronization, not file sharing.
C. IMAP – Email protocol, not related to file sharing.
E. ROP – Not a file-sharing protocol (Return-Oriented Programming = security exploit).
F. LDAP – Directory service for authentication, not file sharing.
Final Answer: B, D
