Lawful bases for processing, data subject rights, and controller obligations are core to most exam items because they directly impact how organizations operate. Principles and terminology also appear frequently because they underpin all other topics. Allocate roughly 30% of your study time to these three domains and distribute the remaining time across sector-specific applications, breaches, and emerging areas like AI.
The seven principles (lawfulness, fairness, transparency, purpose limitation, data minimization, accuracy, and storage limitation) form the foundation for every data protection process. In practice, they guide privacy impact assessments, data retention policies, consent forms, and breach response procedures. Understanding how each principle applies to specific workflows, such as customer onboarding, employee records, or marketing campaigns, helps you answer scenario questions confidently.
Confusing legal bases (e.g., mixing consent with legitimate interest) and misidentifying which regulation applies (GDPR vs. PECR vs. sector-specific rules) are frequent errors. Candidates also sometimes overlook exceptions and special cases, such as public task exemptions or the stricter rules for children's data. Careful reading of scenario details and practice with mixed-topic questions help avoid these pitfalls.
Direct experience with privacy impact assessments, breach handling, or data transfer documentation is valuable but not required. If you have access to real examples, review how your organization documents legal bases, manages consent, or responds to subject access requests. Prioritize understanding the practical steps behind each principle and obligation so that you can apply them to unfamiliar scenarios on the exam.
Shift from learning new topics to consolidation and practice. Complete at least one full-length timed practice test to identify remaining weak areas, then focus revision on those domains. Review key definitions and legal bases using flashcards or summary notes. On the day before the exam, do a light review of high-impact topics (lawful bases, rights, controller obligations) and get adequate sleep to maintain focus during the test.
What is the basis of the accountability and data governance obligation (Article 5 (2) of the GDPR)?
Article 5(2) of the GDPR introduces the principle of accountability, which requires that the controller is responsible for, and be able to demonstrate compliance with, the data protection principles set out in Article 5(1). These principles are: lawfulness, fairness and transparency; purpose limitation; data minimisation; accuracy; storage limitation; integrity and confidentiality; and data protection by design and by default. The controller must implement appropriate technical and organisational measures to ensure and demonstrate compliance, such as policies, procedures, records, audits, reviews, and DPIAs. The controller must also cooperate with the supervisory authority and provide any information requested by it. The other options are not the basis of the accountability and data governance obligation, although they may be related to other obligations under the GDPR.Reference:
ICO guidance on accountability and governance4
Which of the following would NOT be a personal data breach'?
A personal data breach is defined in Article 4(12) of the UK GDPR as ''a breach of security leading to the accidental or unlawful destruction, loss, alteration, unauthorised disclosure of, or access to, personal data transmitted, stored or otherwise processed''. Personal data means any information relating to an identified or identifiable natural person, such as a name, an identification number, location data, an online identifier or factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person. Therefore, a personal data breach only occurs when the security incident affects personal data, not any other type of information. In this case, the accidental deletion of an organisation's information security policy from the public facing website would not be a personal data breach, as the policy does not contain any personal data. However, the other scenarios would be considered personal data breaches, as they involve the loss, alteration, destruction or unauthorised access to personal data of customers, employees or students.Reference:
ICO Guide to Data Protection, Personal Data Breaches3
What is the meaning of storage limitation in relation to UK GDPR Article 5 (1 )(e)?
Storage limitation is one of the principles of data protection under the UK GDPR. It means that personal data should not be kept in a form that allows identification of data subjects for longer than is necessary for the purposes for which the data are processed. The UK GDPR does not specify any fixed time limits for different types of data, but rather requires data controllers to determine and justify the appropriate retention periods for their processing activities, taking into account factors such as the nature, scope, context and purposes of the processing, the risks to the rights and freedoms of data subjects, and the legal obligations and expectations of the data controller. Data controllers should also have a policy setting out standard retention periods where possible, and review the data they hold regularly to ensure that it is erased or anonymised when it is no longer needed. Data subjects have the right to request the erasure of their personal data if the data controller no longer has a lawful basis or a legitimate interest for keeping it. The UK GDPR allows for some exceptions to the storage limitation principle, such as when the personal data is processed solely for archiving purposes in the public interest, scientific or historical research purposes, or statistical purposes, subject to appropriate safeguards for the rights and freedoms of data subjects.Reference:
UK GDPR, Article 5 (1) (e) and (2)4

What factors should be considered when looking at security of processing under Article 32 of the GDPR?
Select the INCORRECT answer
Lawfulness of processing is not a factor that should be considered when looking at security of processing under Article 32 of the GDPR. Lawfulness of processing is a separate requirement that applies to all processing of personal data, regardless of the level of security. Security of processing under Article 32 of the GDPR should be based on the following factors:
The state of the art and the costs of implementation of the security measures;
The nature, scope, context and purposes of the processing;
The risk of varying likelihood and severity for the rights and freedoms of natural persons;
Adherence to an approved code of conduct or an approved certification mechanism (as an element to demonstrate compliance).Reference:
Guidelines 07/2020 on the concepts of controller and processor in the GDPR2, p. 36
Of the following options which is NOT a purpose of carrying out a Data Protection Impact Assessment (DPIA)?
A DPIA is not required to fulfil the requirement that all DPIAs are submitted to the ICO, because this is not a requirement under the GDPR. The GDPR only requires that the controller consults the ICO before carrying out processing that is likely to result in a high risk to individuals, if the controller cannot mitigate that risk. This means that not all DPIAs need to be submitted to the ICO, only those that identify a high residual risk that cannot be reduced. The other options are valid purposes of carrying out a DPIA, as they help the controller to comply with the GDPR, ensure data protection by design and by default, and identify and mitigate the main risks to individuals' rights and freedoms.Reference:
Article 35 and 36 of the GDPR3
