When transmitting a payment instruction, which of the following will help verify that the instruction was not duplicated?
Correct Answer: D
When transmitting data, a sequence number and/or time stamp built into the message to make it unique can be checked by the recipient to ensure that the message was not intercepted and replayed. This is known as replay protection, and could be used toverify that a payment instruction was not duplicated. Use of a cryptographic hashing algorithm against the entire message helps achieve data integrity. Enciphering the message digest using the sender's private key, which signs the sender's digital signature to the document, helps in authenticating the transaction. When the message is deciphered by the receiver using the sender's public key, it ensures that the message could only have come from the sender. This process of sender authentication achieves nonrepudiation .

Correct Answer: B
Question 579
Which of the following is MOST important to determine when conducting an audit Of an organization's data privacy practices?
Correct Answer: D
Explanation The answer D is correct because the most important thing to determine when conducting an audit of an organization's data privacy practices is whether the systems inventory containing personal data is maintained. A systems inventory is a list of all the systems, applications, databases, and devices that store, process, or transmit personal data within the organization. Maintaining a systems inventory is essential for data privacy because it helps the organization to identify, classify, and protect the personal data it holds, as well as to comply with the relevant privacy laws and regulations. A systems inventory also enables the organization to perform data protection impact assessments (DPIAs), data breach notifications, data subject access requests, and data retention and disposal policies. The other options are not as important as option D. Whether a disciplinary process is established for data privacy violations (option A) is a policy issue that may deter or sanction the employees who violate the data privacy rules, but it does not directly affect the data privacy practices of the organization. Whether strong encryption algorithms are deployed for personal data protection (option B) is a technical issue that may enhance the security and confidentiality of the personal data, but it does not address the other aspects of data privacy, such as accuracy, consent, and purpose limitation. Whether privacy technologies are implemented for personal data protection (option C) is also a technical issue that may support the data privacy practices of the organization, but it does not guarantee that the organization follows the best practices or complies with the applicable laws and regulations.
