How does Marketo help ensure compliance with GDPR?

The correct answer highlights Marketo's focus on compliance with GDPR through its integrated features for consent management and data access. This includes tools that enable marketers to capture and manage user consent effectively, ensuring that they can prove that they have permission to store and process individuals' personal data, which is a fundamental requirement under GDPR.

Additionally, Marketo provides functionalities that allow users to easily access their data, request deletion, and manage their preferences. This capability empowers both marketers and consumers to uphold the principles of transparency and control over personal information, which are pivotal aspects of GDPR.

The other responses, while they reference Marketo features, do not directly address compliance with GDPR requirements as effectively as the correct response. For instance, while marketing automation tools are vital for overall campaign management, they do not specifically relate to the legal aspects of handling personal data in line with GDPR stipulations. Data storage limitations are not a blanket requirement of GDPR and can vary based on the nature of the data and its purpose. Lastly, though data encryption is important for security, GDPR compliance specifically requires broader measures related to consent and individual rights, which the consent management tools directly address.
