What does Document Certification do for a document?

• A. Adds a watermark
• B. Encrypts the document
• C. Applies a password
• D. Verifies the authenticity of a document

Answer: (D)

Document Certification is about binding a trusted digital certificate to a document so you can prove who created it and that its content hasn’t been altered since certification. This lets others verify the document’s authenticity and integrity by checking the signature against the issuing certificate. It’s different from adding a watermark, encrypting the file, or applying a password, which are about marking ownership or controlling access. Certification provides a verifiable seal of origin and integrity, and any unauthorized changes would be detectable because they would break the certification.
