Answer : A

Automated data discovery and classification tools provide continuous and systematic identification of data assets across the enterprise, ensuring accuracy and reducing manual errors. Internal updates (B) and departmental reporting (D) depend on human diligence; periodic manual audits (C) are time-bound and may miss changes between reviews.

''Automated discovery ensures a current and reliable data inventory, critical for privacy compliance.''

Answer : B

Validation and certification of data destruction is the most important consideration when choosing a method for data destruction, because it provides evidence that the data has been destroyed beyond recovery and that the organization has complied with the applicable information security frameworks and legal requirements. Validation and certification can also help to prevent data breaches, avoid legal liabilities, and enhance the organization's reputation and trustworthiness. Different methods of data destruction may have different levels of validation and certification, depending on the type of media, the sensitivity of the data, and the standards and guidelines followed. For example, some methods may require a third-party verification or audit, while others may generate a certificate of destruction or a report of erasure. Therefore, the organization should choose a method that can provide sufficient validation and certification for its specific needs and obligations.

Answer : C

The best way to safeguard the encryption keys is to ensure that they are stored in a cryptographic vault. A cryptographic vault is a secure hardware or software module that provides cryptographic services and protects the keys from unauthorized access, modification, or disclosure. A cryptographic vault can also provide other functions, such as key generation, key backup, key rotation, key destruction, and key auditing. A cryptographic vault can enhance the security and privacy of the encrypted data by preventing key compromise, leakage, or misuse. A cryptographic vault can also comply with the security standards and best practices for key management, such as the ISO/IEC 27002, NIST SP 800-57, or PCI DSS.Reference:

Answer : A

Anonymization is a technique that removes or modifies all identifiers in a data set to prevent or limit the identification of the data subjects. Anonymization is the IT privacy practitioner's best recommendation for an organization that uses analytics derived from archived transaction data to create individual customer profiles for customizing product and service offerings, as it would protect the privacy of the customers by reducing the linkability of the data set with their original identity, and also comply with the data minimization principle that requires limiting the collection, storage and processing of personal data to what is necessary and relevant for the intended purposes. Anonymization would also preserve some characteristics or patterns of the original data that can be used for analysis or customization purposes, without compromising the accuracy or quality of the results. The other options are not as effective as anonymization in this situation. Discontinuing the creation of profiles is not a feasible or desirable option, as it would prevent the organization from achieving its business objectives and providing value to its customers. Implementing strong access controls is a security measure that restricts who can access, view or modify the data, but it does not address the issue of collecting or retaining more personal data than necessary or relevant.Encrypting data at rest is a security measure that transforms plain text data into cipher text using an algorithm and a key, making it unreadable by unauthorized parties, but it does not address the issue of collecting or retaining more personal data than necessary or relevant, and may require additional security measures to protect the encryption keys or certificates1, p.75-76Reference:1: CDPSE Review Manual (Digital Version)

Answer : C

Domain name system (DNS) sinkhole is a technology that redirects malicious or unwanted domain names to alternative destinations, such as a fake or harmless website, a warning page, or a null address. DNS sinkhole is the most effective technology deployed at an enterprise level to block malicious tracking of user internet browsing, as it would prevent users from accessing websites that use tracking technologies, such as cookies, web beacons, or fingerprinting, to collect and analyze user behavior or preferences. DNS sinkhole would also protect users from other malicious activities, such as malware distribution, phishing attempts, or botnet command and control. The other options are not as effective as DNS sinkhole in blocking malicious tracking of user internet browsing at an enterprise level. Web application firewall (WAF) is a technology that monitors and filters incoming and outgoing web traffic to protect web applications from attacks, such as cross-site scripting (XSS), SQL injection, or denial-of-service (DoS), but it does not block malicious tracking of user internet browsing. Website URL blacklisting is a method of blocking access to websites that are known or suspected to be malicious or harmful, but it does not block malicious tracking of user internet browsing from unknown or legitimate websites that use tracking technologies.Desktop antivirus software is a technology that scans and removes viruses, malware, spyware, or other threats from desktop computers or devices, but it does not block malicious tracking of user internet browsing from websites that use tracking technologies1, p.92Reference:1: CDPSE Review Manual (Digital Version)
