Barry's preferred communication protocol for uploading files to a web-based storage service with efficiency and security would be C. SFTP (Secure File Transfer Protocol).
SFTP is the most secure option for uploading files to a web-based storage service because it uses strong encryption to protect the data during transmission.
So, FTP, on the other hand, is not secure by default, as it transmits data in plain text, which can be easily intercepted by eavesdroppers. While SMTP and SNMP are also communication protocols, they are not designed for file transfer and do not provide the same level of security as SFTP.
Barry wants to upload a series of files to a web-based storage service, so that people Barry has granted authorization can retrieve these files. Which of the following would be Barry's preferred communication protocol if he wanted this activity to be efficient and secure? (D4, L4.1.2) A.SMTP (Simple Mail Transfer Protocol) B.FTP (File Transfer Protocol) C.SFTP (Secure File Transfer Protocol) D.SNMP (Simple Network Management Protocol)
