Which deployment tool is focused on moving data in mass to the new Implementation tenant?

The correct answer is iLoad, as this deployment tool is specifically designed for the mass loading of data into Workday's Implementation tenant. iLoad is user-friendly and tailored for implementers who need to efficiently transfer large volumes of data, such as employee records, financial data, or configurations from one Workday environment to another. It can handle complex data sets and supports various file formats, making it an essential tool during the implementation process.

Foundation Recipe, while important, is more focused on establishing foundational configurations and best practices within Workday rather than the actual mass migration of data. Object Transporter is primarily used for transporting Workday configuration objects between environments rather than bulk data loading. Advanced Load is used for more sophisticated scenarios in data loading but is not as commonly employed for the straightforward transfer of mass data as iLoad is.
