Selected Answer: C
While file-level encryption (option A) can help protect the confidentiality of files during transmission, it does not specifically prevent the transfer of files to external parties through IM applications. Encryption ensures that files are securely transmitted, but it does not control whether files are sent externally.

Selected Answer: C
Correct answer is C. B is not a solution, app level firewall is not a DLP solution. If IM is allowed in the org, app level firewall wont prevent sharing sensitive files over IM. What you need is a DLP solution, but that is not part of the answers, so Policy is the next best choice.

I think answer is B because it's asking to prevent the transfer of files so it has to be stopped. Application level firewall should be able to do it.
