As others have said, they are looking for reasons why you need somebody with advanced degree/training/experience for the job. How the applicant's degree will be used on a day to day basis. For example, given a transcript, how will the experience from the courses listed be used? Provide details for other employees with the same job title. For example, if the roles and responsibilities include production support, provide ticket counts and some summary info. An example "day in the life" for the job, task by task and hour by hour. The RFE guidance will differ because it is a recommendation from your legal team on what you should provide to get the application through.
