Actual exam question from Microsoft's 70-467

Question #: 102
Topic #: 1

You are designing a partitioning strategy for a SQL Server Analysis Services (SSAS) cube. New data is loaded in real-time into the data warehouse that feeds the cube. Between 10 million and 15 million rows of data are loaded into the main fact table each day from a Microsoft Azure SQL Database.
You have the following requirements:
✑ Maximize cube query performance during business hours.
✑ Ensure that data is available in the cube as soon as possible after it is loaded into the data warehouse.
You need to design a partitioning strategy that meets the requirements.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

A. Partition the cube by day for history, using hybrid OLAP (HOLAP) storage mode. Create a daily partition that uses multidimensional OLAP (MOLAP) storage mode during the day. Reprocess the partition incrementally during the day.
B. Partition the cube by week for history. Create a daily partition that uses multidimensional OLAP (MOLAP) storage mode. Process the partition periodically to add new data.
C. Partition the cube by day for history, using multidimensional OLAP (MOLAP) storage mode. Create a daily partition that uses proactive caching during the day. Reprocess the partition in full MOLAP storage mode at night
D. Partition the cube by day for history, using multidimensional OLAP (MOLAP) storage mode. Create a daily partition that uses relational OLAP (ROLAP) storage

This can't be A because "incremental" add to the database doesn't satisfy the requirement of getting the data as soon as possible.
