CompTIA Network+ (N10-007) — Question 610

A network technician needs to distribute an updated OS for all network switches at company locations throughout the world. The technician wants to ensure file integrity since several locations do not have high-quality connectivity to the Internet.
Which of the following methods should be used to distribute the images while ensuring integrity?

Answer options

• A. Use a TFTP server and UDP protocol.
• B. Use an FTP server and provide the file hash.
• C. Use an HTTP server to share the file.
• D. Use a modem and dial-up connection.

Correct answer: B

Explanation

The correct answer is B because using an FTP server allows the technician to provide a file hash, which ensures the integrity of the distributed files. Options A and C do not offer a method for verifying file integrity, while D is an outdated method that would not be efficient for distributing large files like operating system images.
