Methods for Ensuring File Integrity during OS Distribution

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?

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.

B.

Option B is the correct answer: Use an FTP server and provide the file hash.

To distribute an updated OS for all network switches at company locations throughout the world, the network technician must consider several factors, such as ensuring file integrity and handling the issue of low-quality connectivity at some locations.

Using a TFTP server and UDP protocol (Option A) is not a good choice since UDP is an unreliable protocol that does not provide any error checking or reliability, making it unsuitable for transferring large files over a long distance.

Using an HTTP server to share the file (Option C) might be a good choice for file distribution, but it doesn't provide file integrity checks, which means that there is no way to ensure that the file has not been tampered with during the transfer.

Using a modem and dial-up connection (Option D) is not an ideal solution since it is an outdated technology that is slow and prone to errors, which could cause significant delays and potential corruption of the file.

Using an FTP server and providing the file hash (Option B) is the best solution since it allows for a reliable file transfer while also ensuring the file's integrity. FTP is a reliable protocol that provides error checking and can handle low-quality connectivity. Additionally, providing the file hash allows the recipients to verify the file's integrity and ensure that it has not been tampered with during the transfer.

In summary, the best method to distribute the updated OS for all network switches at company locations throughout the world while ensuring file integrity is to use an FTP server and provide the file hash.
