SCENARIO
Please use the following to answer the next question:
Sandy recently joined Market4U, an advertising technology company founded in 2016, as their VP of Privacy and Data Governance. Through her first initiative in conducting a data inventory, Sandy learned that Market4U maintains a list of 19 million global contacts that were collected throughout the course of Market4U's existence. Knowing the risk of having such a large amount of data, Sandy wanted to purge all contacts that were entered into Market4U's systems prior to May 2018, unless such contacts had a more recent interaction with Market4U content. However, Dan, the VP of Sales, informed Sandy that all of the contacts provide useful information regarding successful marketing campaigns and trends in industry verticals for Market4U's clients.
Dan also informed Sandy that he had wanted to focus on gaining more customers within the sports and entertainment industry. To assist with this behavior, Market4U's marketing team decided to add several new fields to Market4U's website forms, including forms for downloading white papers, creating accounts to participate in Market4U's forum, and attending events. Such fields include birth date and salary.
What should Sandy give as feedback to Dan and the marketing team regarding the new fields Dan wants to add to Market4U's forms?

SCENARIO
Please use the following to answer the next question:
Zandelay Fashion ('Zandelay') is a successful international online clothing retailer that employs approximately 650 people at its headquarters based in Dublin, Ireland. Martin is their recently appointed data protection officer, who oversees the company's compliance with the General Data Protection Regulation (GDPR) and other privacy legislation.
The company offers both male and female clothing lines across all age demographics, including children. In doing so, the company processes large amounts of information about such customers, including preferences and sensitive financial information such as credit card and bank account numbers.
In an aggressive bid to build revenue growth, Jerry, the CEO, tells Martin that the company is launching a new mobile app and loyalty scheme that puts significant emphasis on profiling the company's customers by analyzing their purchases. Martin tells the CEO that: (a) the potential risks of such activities means that Zandelay needs to carry out a data protection impact assessment to assess this new venture and its privacy implications; and (b) where the results of this assessment indicate a high risk in the absence of appropriate protection measures. Zandelay may have to undertake a prior consultation with the Irish Data Protection Commissioner before implementing the app and loyalty scheme.
Jerry tells Martin that he is not happy about the prospect of having to directly engage with a supervisory authority and having to disclose details of Zandelay's business plan and associated processing activities.
What must Zandelay provide to the supervisory authority during the prior consultation?

In which of the following cases, cited as an example by a WP29 guidance, would conducting a single data protection impact assessment to address multiple processing operations be allowed?
