Question 1

Scenario 8: MA store is an online clothing retailer founded in 2010. They provide quality products at a reasonable cost. One thing that differentiates MA store from other online shopping sites is their excellent customer service.

MA store follows a customer-centered business approach. They have created a user-friendly website with well-organized content that is accessible to everyone. Through innovative ideas and services, MA store offers a seamless user experience for visitors while also attracting new customers. When visiting the website, customers can filter their search results by price, size, customer reviews, and other features. One of MA store's strategies for providing, personalizing, and improving its products is data analytics. MA store tracks and analyzes the user actions on its website so it can create customized experience for visitors.

In order to understand their target audience, MA store analyzes shopping preferences of its customers based on their purchase history. The purchase history includes the product that was bought, shipping updates, and payment details. Clients' personal data and other information related to MA store products included in the purchase history are stored in separate databases. Personal information, such as clients' address or payment details, are encrypted using a public key. When analyzing the shopping preferences of customers, employees access only the information about the product while the identity of customers is removed from the data set and replaced with a common value, ensuring that customer identities are protected and cannot be retrieved.

Last year, MA store announced that they suffered a personal data breach where personal data of clients were leaked. The personal data breach was caused by an SQL injection attack which targeted MA store's web application. The SQL injection was successful since no parameterized queries were used.

Based on this scenario, answer the following Questio n:

According to scenario 8, by storing clients' information in separate databases, MA store used a:



Answer : A

Separating databases for different types of data aligns with the principle of Data Protection by Design and by Default under Article 25 of GDPR. By structuring data storage in a way that limits access and minimizes exposure, MA Store is proactively implementing security measures that prevent unauthorized access and mitigate risks in case of a breach. This approach supports the confidentiality, integrity, and availability of personal data as required by GDPR.

Last year, MA store announced that they suffered a personal data breach where personal data of clients were leaked. The personal data breach was caused by an SQL injection attack which targeted MA store's web application. The SQL injection was successful since no parameterized queries were used.

Based on this scenario, answer the following Questio n:

How could MA store prevent the SQL attack described in scenario 8?



Answer : A

The SQL injection attack exploited vulnerabilities in the web application due to the lack of parameterized queries. GDPR mandates security measures under Article 32, which includes data integrity and confidentiality safeguards. Using parameterized queries and prepared statements at the database level would prevent attackers from injecting malicious SQL code. TLS encryption (option B) is crucial for secure communication but does not directly address SQL injection threats. Similarly, data minimization (option C) is a general best practice but does not provide specific protection against SQL injection.


Question 3

Scenario 8: MA store is an online clothing retailer founded in 2010. They provide quality products at a reasonable cost. One thing that differentiates MA store from other online shopping sites is their excellent customer service.

Based on this scenario, answer the following Questio n:

What did MA store use when storing clients' address and payment details in its system?



Answer : B

MA Store uses encryption with a public key to protect clients' addresses and payment details, which aligns with the definition of pseudonymization under Article 4(5) of GDPR. Pseudonymization is a technique that reduces the linkability of data subjects to their personal data, thus minimizing the risk of unauthorized access. Encryption is specifically mentioned as a security measure in Article 32(1)(a) of GDPR, reinforcing that personal data should be protected against unauthorized access or breaches.


Question 4

Scenario 8: MA store is an online clothing retailer founded in 2010. They provide quality products at a reasonable cost. One thing that differentiates MA store from other online shopping sites is their excellent customer service.

Based on this scenario, answer the following Questio n:

According to scenario 8, MA store analyzed shopping preferences of its customers by analyzing the product they have bought in the customer's purchase history. Which option is correct in this case?



Answer : B

Since the data is pseudonymized (not fully anonymized), it remains personal data under GDPR and cannot be retained indefinitely. Article 5(1)(e) of GDPR states that personal data must be kept only for as long as necessary for the intended processing purpose. Additionally, Recital 26 of GDPR clarifies that pseudonymized data is still considered personal data if re-identification is possible. Therefore, MA Store must implement a retention policy that ensures the data is deleted or further anonymized once it is no longer needed for analysis.

Based on this scenario, answer the following Questio n:

Which de-identification method has MA store used when analyzing the shopping preferences of its customers?



Answer : B

MA Store replaces customer identities with a common value when analyzing shopping preferences, ensuring that the data subject's identity cannot be retrieved. This method aligns with k-anonymity, where personal identifiers are removed or generalized to protect individuals from re-identification. The goal of k-anonymity is to prevent unique identification by ensuring that each data entry is indistinguishable from at least k-1 other entries. This is an effective way to process data while maintaining compliance with GDPR principles of data minimization (Article 5(1)(c)) and anonymization.


Question 6

Questio n:

Under GDPR, the controller must demonstrate that data subjects have consented to the processing of their personal data, and the consent must be freely given.

What is the role of the DPO in ensuring compliance with this requirement?



Answer : B

Under Article 7(1) of GDPR, controllers must be able to demonstrate that the data subject has given consent. The DPO advises on ensuring these procedures are in place but does not collect or approve consent directly.

Option B is correct because the DPO must verify that consent records exist and meet GDPR standards.

Option A is incorrect because informing data subjects about withdrawal rights is the controller's duty, not the DPO's.

Option C is incorrect because the DPO does not personally maintain consent logs.

Option D is incorrect because DPOs do not approve legal bases for processing---this is the controller's responsibility.


GDPR Article 7(1) (Controller must demonstrate valid consent)

GDPR Article 39(1)(b) (DPO ensures compliance with data protection obligations)

Question 7

Scenario:

ChatBubble is a software company that stores personal data, including usernames, emails, and passwords. Last month, an attacker gained access to ChatBubble's system, but the personal data was encrypted, preventing unauthorized access.

Questio n:

Should the data subjects be notified in this case?



Answer : C

Under Article 34(3)(a) of GDPR, if personal data is encrypted or otherwise protected, notification to data subjects is not required unless the risk is high.

Option C is correct because encryption renders the data unintelligible to unauthorized parties, reducing risk.

Option A is incorrect because not all breaches require data subject notification---only those posing high risks.

Option B is incorrect because the number of affected individuals does not determine notification requirements.

Option D is incorrect because notification is based on risk assessment, not supervisory authority requests alone.


GDPR Article 34(3)(a) (No notification required if encryption makes data inaccessible)

Recital 86 (Notification is necessary only if data loss poses a significant risk)
