Online Power Query MCQs with Answers

  • Which sources does Power Query allow us to Get Data from?
  • What would happen if you tried to create a query from data in the current workbook that is not part of a table or a named range?
  • In Australia, the first two digits represent the area code for a phone number, such as 0223789456. Consider a field that contains phone numbers in this format. What would be the appropriate option under Split Column to extract the area code?
  • If you are utilising Power Query primarily as a ‘working space’ without viewing the data in your spreadsheet within Close & Load to, you should choose the option:
  • After creating a new Table via Power Query, what would happen when the original data is edited or changed?
  • When getting data from another workbook, it is essential to transform the data within that workbook first.
  • What are some differences between Power Query and standard Excel?
  • Imdad was working in Power Query and loaded the data into a new worksheet. He notices that he has made an error and needs to undo one of his steps. What should he do?
  • When getting data from a database, unlike getting data from a spreadsheet, you have to transform the data at the source first.
  • There are currently three columns in Power Query: Street Address, City, and State, with data such as “42 Wallaby Way” (Street Address), “Sydney” (City), and “NSW” (State). What could we do to create a new column that displayed the full address as a single string, such as “42 Wallaby Way, Sydney, NSW”?
  • If you created a table in Excel after getting data from a database, changing the data in the new table will update the original database if you click Refresh.
  • An American company has 50 offices, one in each state, which all use their own Excel spreadsheet for their human resources data, but the parent company wants to maintain a separate spreadsheet that gets the data from all these files. What would be an efficient solution to this problem?
  • When getting data from a folder, the preview panel only shows a preview of the first file. Suppose there is an Australian company with an office in each of the 8 states and territories, where the parent office is in the state of New South Wales. If the 8 files are named as below, which file will appear in the preview pane, and why? Western Australia South Australia Northern Territory Tasmania Victoria Australian Capital Territory New South Wales Queensland
  • Suppose that we have created a new table by getting data from a folder that contains data from each of 5 branches of a company, each with its file. What should we do if we open two new branches – that maintains the existing structure and also gives unique information for each branch in its file?
  • Which aspect of getting data from a folder is similar to the result of an Append Query?
  • When using an Append Query, the two tables must:
  • Suppose we created 2 queries, one for Sydney and one for Other Instructors. We did not load these into the worksheet; and we only created a connection. Due to this setup, when choosing to append these queries, the result cannot be loaded into the worksheet – we can only create a connection.
  • When getting data from a PDF that contains a table in each of the 5 pages, what will we see in the preview panel?
  • When getting data from a PDF that contains a table in each of 5 pages and selecting multiple items, this will create as many queries as the number of items you have selected.
  • When getting data from a PDF that contains multiple pages, what would be a query that would be usually run, right at the end?
