According to the Free CIPP/E Study Guide, page 14, "the GDPR requires controllers to carry out a data protection impact assessment (DPIA) prior to processing where a type of processing, in particular using new technologies, and taking into account the nature, scope, context and purposes of the processing, is likely to result in a high risk to the rights and freedoms of natural persons." The GDPR also provides a list of examples of processing operations that require a DPIA, such as "a systematic and extensive evaluation of personal aspects relating to natural persons which is based on automated processing, including profiling, and on which decisions are based that produce legal effects concerning the natural person or similarly significantly affect the natural person" (Article 35(3)(a)). Therefore, the fact that Dynaroux plans to undertake profiling of its customers through analysis of their purchasing patterns would trigger a DPIA under the GDPR, as it involves a systematic and extensive evaluation of personal aspects based on automated processing that may significantly affect the customers. The other options are not necessarily cases where a DPIA is required, although they may involve other obligations under the GDPR, such as obtaining a valid legal basis, providing adequate safeguards, or informing the data subjects.

GDPR, Article 35

Under the GDPR, using CCTV on business premises involves the processing of personal data, which requires compliance with the data protection principles and obligations. However, notifying the appropriate data protection authority (DPA) is not one of the steps that a company should take before using CCTV, unless the DPA has specifically requested it or the CCTV involves high-risk processing that requires prior consultation. The other steps are necessary to ensure GDPR compliance, as explained below:
Performing a data protection impact assessment (DPIA) is a mandatory requirement for any type of processing that is likely to result in a high risk to the rights and freedoms of individuals, such as large-scale or systematic monitoring of public areas. A DPIA is a process that helps identify and mitigate the potential privacy risks of using CCTV, and document the measures taken to address them. A DPIA should include a description of the processing, its purpose and necessity, its risks and benefits, the safeguards and security measures, and the consultation with stakeholders. A DPIA should be carried out before the CCTV system is installed or upgraded, and reviewed regularly or whenever there is a significant change in the processing.
Creating an information retention policy for those who operate the system is a good practice to ensure that the personal data collected by CCTV is not kept longer than necessary for the purpose for which it was collected, and that it is securely deleted or anonymised when no longer needed. The retention period should be determined by the specific purpose and context of using CCTV, and take into account any legal or contractual obligations, as well as the expectations and rights of the data subjects. The retention policy should also specify who is responsible for managing and deleting the CCTV footage, and how the deletion process is verified and documented.
Ensuring that safeguards are in place to prevent unauthorized access to the footage is an essential requirement to comply with the GDPR principle of integrity and confidentiality, which states that personal data must be processed in a manner that ensures appropriate security of the data, including protection against unauthorized or unlawful processing and accidental loss, destruction or damage. The safeguards may include technical and organisational measures, such as encryption, access control, logging, audit, training, policies and procedures, that aim to protect the CCTV footage from unauthorized or unlawful access, disclosure, alteration, or destruction, both during transmission and storage.

The GDPR establishes a two-tier system of administrative fines for infringements of its provisions, depending on the nature, gravity, and duration of the infringement, as well as other factors such as the intentional or negligent character of the infringement, the actions taken to mitigate the damage, the degree of co-operation with the supervisory authority, and any previous infringements1. The lower tier of fines can be up to 10 million euros or 2% of the total worldwide annual turnover of the preceding financial year, whichever is higher1. The lower tier of fines applies to infringements of the GDPR relating to the following aspects1:
The obligations of the controller and the processor pursuant to Articles 8, 11, 25 to 39, and 42 and 43; The obligations of the certification body pursuant to Articles 42 and 43; The obligations of the monitoring body pursuant to Article 41 (4). The higher tier of fines can be up to 20 million euros or 4% of the total worldwide annual turnover of the preceding financial year, whichever is higher1. The higher tier of fines applies to infringements of the GDPR relating to the following aspects1:
The basic principles for processing, including conditions for consent, pursuant to Articles 5, 6, 7, and 9; The data subjects' rights pursuant to Articles 12 to 22; The transfers of personal data to a recipient in a third country or an international organisation pursuant to Articles 44 to 49; Any obligations pursuant to Member State law adopted under Chapter IX; Non-compliance with an order or a temporary or definitive limitation on processing or the suspension of data flows by the supervisory authority pursuant to Article 58 (2) or failure to provide access in violation of Article 58 (1). Therefore, higher fines are assessed for GDPR violations due to violations of a data subject's rights, as these are among the infringements that fall under the higher tier of fines. Data subjects' rights are the rights granted to individuals whose personal data are processed by controllers or processors, such as the right to access, rectify, erase, restrict, object, or port their data, as well as the right to be informed, to withdraw consent, and to lodge a complaint1. Violations of these rights can cause significant harm to the data subjects and undermine the objectives of the GDPR. Therefore, option D is the correct answer.

According to the Free CIPP/E Study Guide, page 14, "if the DPIA indicates that the processing would result in a high risk in the absence of measures taken by the controller to mitigate the risk, the controller shall consult the supervisory authority prior to the processing." This means that the controller must seek the advice of the supervisory authority when the DPIA identifies high risks that cannot be sufficiently reduced by the controller's own measures. The other options are not necessarily cases where the consultation is required, although they may trigger other obligations under the GDPR, such as obtaining a valid legal basis, providing adequate safeguards, or informing the data subjects.

GDPR, Article 36

According to Article 14 of the GDPR, the data controller must provide the data subject with certain information when collecting personal data from a source other than the data subject1. However, there are some exceptions to this obligation, such as when the data subject already has the information, or when the provision of such information proves impossible or would involve a disproportionate effort2. The latter exception may apply, for example, when the personal data are collected from a large number of sources, or when the personal data are processed for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes3. The data controller must take appropriate measures to protect the data subject's rights and interests, and make the information publicly available2.
