We continuously refresh our question bank with:The newest Power BI features and updatesCurrent industry trends and best practicesReal-world interview scenariosPreview Our Course ContentGet a taste of our training with these 3 sample questions - complete with detailed explanations that show how we prepare you for success:Question 1:Your Power BI report with the `orders` table (1M+ rows) loads slowly. Analysis shows high memory usage from the `order_date` column. Auto date/time is disabled. What should you do?A) Enable auto date/time for the `orders` table B) Change `order_date` data type to Text C) Create a custom date table with integer keys and relate it to `orders` D) Split `order_date` into separate year/month/day columns Answer: C Explanation: A custom date table with integer keys reduces memory usage vs. datetime storage. Option A increases model size. Option B breaks time intelligence. Option D complicates calculations without solving the root issue.::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::Question 2:You need to implement RLS so customers can only see their own orders in a Power BI report. Which DAX filter expression should you use in a security role?A) ```daxorders[customer_id] = USERNAME()```B) ```daxorders[customer_id] = LOOKUPVALUE(customers[customer_id], customers[email], USERPRINCIPALNAME())```C) ```daxcustomers[email] = USERPRINCIPALNAME()```D) ```daxPATHCONTAINS(USEROBJECTID(), orders[customer_id])```Answer: B Explanation: Option B correctly matches the logged-in user's email (via `USERPRINCIPALNAME()`) to the customer ID. Option A assumes `USERNAME()` returns customer_id. Option C filters the customers table but won't propagate to orders without bidirectional filtering. Option D uses incorrect functions.::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::Question 3:You want to create a report with two views: (1) Sales by category, (2) Detailed product performance. Users should toggle between views with a button. Which feature should you configure?A) Sync slicers across both pages B) Bookmarks with visibility toggles for visuals C) Drill-through filters from category to product D) Conditional formatting based on page number Answer: B Explanation: Bookmarks with visibility toggles allow switching between views. Option A synchronizes filters but doesn't hide visuals. Option C enables navigation but not view switching. Option D is irrelevant to this requirement.
