What is the primary purpose of password protection in PDFs? A. To prevent unauthorized opening of the document B. To restrict editing or printing C. To ensure data encryption D. Both A and B Correct Answer: D. Both A and B Explanation: Password protection in PDFs serves multiple security functions. Primarily, it restricts unauthorized users from opening the document, ensuring confidentiality. Additionally, passwords can be used to restrict editing, copying, printing, or extracting content, thereby safeguarding the document's integrity and intended use. Encryption is an underlying mechanism but not the sole purpose; passwords act as keys to access or restrict features. --- 2. Which encryption algorithm is commonly used in PDF security? A. RSA B. AES C. DES D. Both A and B Correct Answer: D. Both A and B Explanation: Modern PDFs typically employ robust encryption algorithms such as AES (Advanced Encryption Standard) for content encryption, offering high-security levels. RSA (Rivest–Shamir–Adleman) is often used for digital signatures and key exchange processes within PDF security frameworks. Combining asymmetric (RSA) and symmetric (AES) encryption methods enhances overall document security. --- 3. What role do digital signatures play in PDF security? A. To encrypt the content of the PDF B. To verify the authenticity and integrity of the document C. To restrict access to the PDF D. To allow editing of the document Correct Answer: B. To verify the authenticity and integrity of the document Explanation: Digital signatures in PDFs serve as electronic "fingerprints," confirming that the document originates from a trusted source and has not been altered since signing. They do not encrypt the entire content but instead provide verification of origin and integrity. This is crucial in legal, financial, and official communications. --- 4. Which feature allows for the permanent removal of sensitive information from a PDF? A. Redaction B. Encryption C. Password protection D. Digital signing Correct Answer: A. Redaction Explanation: Redaction is the process of permanently obscuring or removing sensitive or confidential information from a document. Unlike encryption, which can be reversed with the correct key, redaction ensures that the information cannot be recovered, making it ideal for compliance with privacy regulations. --- 5.
