Answer

Access logs

Answer

Data masking

Question 6

What does a 'Privacy-Enhancing Technology' (PET) primarily aim to achieve?

Accepted Answer

Minimizing or protecting personal data. PETs are tools that protect personal data by minimizing it, masking it, or providing mathematical privacy guarantees.

Answer

Increasing processing power

Answer

Improving network bandwidth

Answer

Reducing software bugs

Question 7

Which TWO technical controls are effective for limiting the scope of PII access in a cloud-based SQL environment?

Accepted Answer

Column-level security. Column-level security and Row-level security provide the most granular access control to prevent unauthorized PII visibility.

Answer

Public network access

Answer

Full database export

Answer

Verbose error logging

Question 8

Which THREE privacy engineering activities are performed during the 'Maintenance' phase of the system lifecycle?

Accepted Answer

Patching security vulnerabilities. Continuous monitoring, re-assessing impact, and updating security patches are critical during maintenance.

Answer

Initial design wireframing

Answer

Project budget estimation

Question 9

In the context of 'Privacy-Preserving Machine Learning', what is the purpose of the 'Membership Inference Attack' simulation during testing?

Accepted Answer

To identify if training data is leaked. This simulation tests if a model reveals whether a specific individual's data was used in the training set, exposing a potential privacy breach.

Answer

To optimize model accuracy

Answer

To improve training speed

Answer

To validate input quality

Question 10

A privacy engineer is implementing differential privacy in a data analytics pipeline. To ensure the privacy budget remains intact over multiple queries, which technique should be applied?

Accepted Answer

Utilizing composition theorems to track cumulative privacy loss. Composition theorems in differential privacy allow for the tracking of the cumulative privacy loss (epsilon) as multiple queries are performed on the same dataset.

Answer

Implementing k-anonymity on the original dataset

Answer

Increasing the sensitivity of the query function

Answer

Applying a fixed noise distribution regardless of query count

Question 11

How can an organization ensure privacy is considered during the vendor procurement phase?

Accepted Answer

Including privacy and data security requirements in the RFP.. Embedding privacy requirements into the Request for Proposal (RFP) sets expectations early.

Answer

Hiring the vendor based solely on price.

Answer

Waiting until the contract is signed before asking for privacy details.

Answer

Allowing the vendor to provide their own privacy policy.

Question 12

Which TWO techniques should be used to protect PII in non-production environments to ensure the data remains non-identifiable?

Accepted Answer

Pseudonymization. Anonymization and pseudonymization (if key access is restricted) are standard methods for protecting non-prod data.

Answer

Full database mirroring

Answer

Public internet exposure

Answer

Plaintext replication

Question 13

When implementing Privacy by Design (PbD) in a new mobile application, which TWO of the following are considered proactive technical controls?

Accepted Answer

Default privacy settings. Data minimization and privacy-default configurations are foundational proactive PbD controls.

Answer

Periodic external audits

Answer

End-user training

Answer

Comprehensive incident response plan

Question 14

An organization uses a 'Privacy-preserving Synthetic Data' generator. What is the primary purpose of this tool in a development environment?

Accepted Answer

To enable testing without using actual production PII. Synthetic data mimics the statistical properties of real data without containing actual PII, allowing devs to test without privacy risk.

Answer

To replace the need for database backups

Answer

To verify the identity of developers

Answer

To increase the accuracy of machine learning models

Question 15

When designing a privacy-preserving data pipeline, which TWO strategies help achieve 'Data Minimization'?

Answer

Disabling all audit logging

Answer

Increasing the retention period for backups

Answer

Storing all raw data in a data lake for future use
