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:

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 2

When pseudonymization is used in a dataset, the data is divided into restricted access data and non-identifiable dat

a. This restricted access data includes gender, occupation, and age, whereas the non-identifiable data includes only nationality. Is this correct?



Answer : B

Pseudonymization does not remove data identifiability but rather reduces the direct link to an individual (GDPR Article 4(5)). Non-identifiable data includes attributes like gender and occupation, whereas restricted access data includes directly identifying details such as names. Anonymization, not pseudonymization, ensures complete irreversibility.


Question 3

Scenario 4:

Berc is a pharmaceutical company headquartered in Paris, France, known for developing inexpensive improved healthcare products. They want to expand to developing life-saving treatments. Berc has been engaged in many medical researches and clinical trials over the years. These projects required the processing of large amounts of data, including personal information. Since 2019, Berc has pursued GDPR compliance to regulate data processing activities and ensure data protection. Berc aims to positively impact human health through the use of technology and the power of collaboration. They recently have created an innovative solution in participation with Unty, a pharmaceutical company located in Switzerland. They want to enable patients to identify signs of strokes or other health-related issues themselves. They wanted to create a medical wrist device that continuously monitors patients' heart rate and notifies them about irregular heartbeats. The first step of the project was to collect information from individuals aged between 50 and 65. The purpose and means of processing were determined by both companies. The information collected included age, sex, ethnicity, medical history, and current medical status. Other information included names, dates of birth, and contact details. However, the individuals, who were mostly Berc's and Unty's customers, were not aware that there was an arrangement between Berc and Unty and that both companies have access to their personal data and share it between them. Berc outsourced the marketing of their new product to an international marketing company located in a country that had not adopted the adequacy decision from the EU commission. However, since they offered a good marketing campaign, following the DPO's advice, Berc contracted it. The marketing campaign included advertisement through telephone, emails, and social medi

a. Berc requested that Berc's and Unty's clients be first informed about the product. They shared the contact details of clients with the marketing company. Based on this scenario, answer the following Questio n:

Questio n:

Based on scenario 4, Berc shared personal information of its clients with an international marketing company even though an adequacy decision was absent. Which of the following is a valid reason to do so?



Answer : C

Under Article 46 of GDPR, in the absence of an adequacy decision, controllers can transfer data only if appropriate safeguards (e.g., Standard Contractual Clauses, Binding Corporate Rules) are in place.

Option C is correct because safeguards such as SCCs allow data transfers when no adequacy decision exists.

Option A is incorrect because adequacy decisions are a legal requirement, not optional.

Option B is incorrect because a CISO cannot authorize GDPR data transfers.

Option D is incorrect because reputation does not ensure GDPR compliance.

Recital 108 (Legally binding commitments for data protection)

Question 4

Scenario: 2

Soyled is a retail company that sells a wide range of electronic products from top European brands. It primarily sells its products in its online platforms (which include customer reviews and ratings), despite using physical stores since 2015. Soyled's website and mobile app are used by millions of customers. Soyled has employed various solutions to create a customer-focused ecosystem and facilitate growth. Soyled uses customer relationship management (CRM) software to analyze user data and administer the interaction with customers. The software allows the company to store customer information, identify sales opportunities, and manage marketing campaigns. It automatically obtains information about each user's IP address and web browser cookies. Soyled also uses the software to collect behavioral data, such as users' repeated actions and mouse movement information. Customers must create an account to buy from Soyled's online platforms. To do so, they fill out a standard sign-up form of three mandatory boxes (name, surname, email address) and a non-mandatory one (phone number). When the user clicks the email address box, a pop-up message appears as follows: ''Soyled needs your email address to grant you access to your account and contact you about any changes related to your account and our website. For further information, please read our privacy policy.' When the user clicks the phone number box, the following message appears: ''Soyled may use your phone number to provide text updates on the order status. The phone number may also be used by the shipping courier." Once the personal data is provided, customers create a username and password, which are used to access Soyled's website or app. When customers want to make a purchase, they are also required to provide their bank account details. When the user finally creates the account, the following message appears: ''Soyled collects only the personal data it needs for the following purposes: processing orders, managing accounts, and personalizing customers' experience. The collected data is shared with our network and used for marketing purposes." Soyled uses personal data to promote sales and its brand. If a user decides to close the account, the personal data is still used for marketing purposes only. Last month, the company received an email from John, a customer, claiming that his personal data was being used for purposes other than those specified by the company. According to the email, Soyled was using the data for direct marketing purposes. John requested details on how his personal data was collected, stored, and processed. Based on this scenario, answer the following Questio n:

Questio n:

The GDPR indicates that the processing of personal data should be based on a legal contract with the data subject. Based on scenario 6, has Soyled fulfilled this requirement?



Answer : C

Under Article 6(1) of GDPR, processing personal data must have a lawful basis, such as consent, contract, legal obligation, or legitimate interest. Additionally, under Article 13, controllers must inform users before collecting their data.

Soyled failed to disclose that personal data would be shared with the network before collection, which violates GDPR transparency requirements. Option C is correct. Option A is incorrect because informing about email collection does not mean lawful processing. Option B is incorrect because the information was not disclosed at the right time. Option D is incorrect because explicit consent is not necessarily required if another lawful basis applies.


GDPR Article 6(1) (Lawfulness of processing)

GDPR Article 13(1) (Transparency in data processing)

Question 5

Why should the controller implement appropriate technical and organizational measures?



Answer : B

GDPR Article 25 requires controllers to implement appropriate measures ensuring data protection. This includes transparency measures that allow data subjects to monitor the processing of their personal data, fulfilling their rights under Articles 12-22.

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:

Questio n:

Based on scenario 2, Soyled only has three mandatory fields in its sign-up form. On which GDPR principle is this decision based?



Answer : C

Under Article 5(1)(c) of GDPR, the data minimization principle states that personal data must be adequate, relevant, and limited to what is necessary for processing.

Soyled's decision to have only three mandatory fields (name, surname, and email) aligns with data minimization since it only collects the minimum data needed for account creation. Option C is correct. Option A is incorrect as transparency relates to informing users. Option B is incorrect because purpose limitation focuses on using data only for specific purposes. Option D is incorrect because storage limitation concerns data retention periods.
