You have a prospective customer list that contains 1,500 rows of data. The list contains the following fields:
1. First name
2. Last name
3. Email address
4. State/Region
5. Phone number
You import the list into Power Query Editor. You need to ensure that the list contains records for each State/Region to which you want to target a marketing campaign.

A. Open the Advanced Editor.
B. Select Column quality.
C. Enable Column profiling based on the entire dataset.
D. Select Column distribution.
E. Select Column profile.
Correct Answer: CE
In the Power query, the load preview by default is 1000 rows. By default, the column quality also only looks at the first 1000 rows. You can verify this by the status bar at the bottom of the Power query window. To change the profiling so it analyses the entire column of data, select the profiling status in the status bar. Then select Column profiling based on the entire data set.

NEW QUESTION 12
You create a dataset sourced from dozens of flat files in Azure Blob storage. The dataset uses incremental refresh. From powerbi.com, you deploy the dataset and several related reports to Microsoft Power BI Premium capacity. You discover that the dataset refresh fails after the refresh runs out of resources.
What is a possible cause of the issue?
A. Query folding is not occurring.
B. You selected Only refresh complete periods.
C. The data type of the column used to partition the data changed.
D. A filter is missing on the report.
Correct Answer: A
The Power BI service partitions data based on a date range. This is what enables only certain partitions to be refreshed incrementally. To make this work, the partition filter conditions are pushed down to the source system by including them in the queries. Using Power Query terminology, this is called “query folding”. It is not recommended that incremental refresh is used when the required query folding cannot take place.
