CompTIA Security+ (SY0-601) — Question 827

A tax organization is working on a solution to validate the online submission of documents. The solution should be carried on a portable USB device that should be inserted on any computer that is transmitting a transaction securely. Which of the following is the BEST certificate for these requirements?

Answer options

Correct answer: A

Explanation

A User certificate is specifically designed to authenticate individual users, making it the most suitable choice for validating online document submissions from a USB device. A Self-signed certificate lacks the trustworthiness needed for secure transactions, while a Computer certificate focuses on device authentication rather than individual users. A Root certificate is used to establish trust for other certificates, but it does not directly validate submissions.
