20+ practice questions focused on Deploy and maintain assets — one of the most tested topics on the Microsoft Power BI Data Analyst PL-300 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Deploy and maintain assets PracticeYour Power BI dataset uses DirectQuery to an Azure SQL Database. Users complain that the report is slow. You need to improve query performance without changing the data source. What should you do?
Explanation: Reducing the number of columns and rows retrieved by report visuals directly minimizes the amount of data sent from Azure SQL Database to Power BI via DirectQuery. Since DirectQuery sends native queries to the source for each visual interaction, fewer columns and rows mean smaller, faster queries, which reduces overall latency without altering the underlying data source.
You have a Power BI dataset that is refreshed every hour from an on-premises data source using an enterprise gateway. The refresh consistently fails at 2:00 AM. What is the most likely cause?
Explanation: The consistent failure at exactly 2:00 AM strongly points to a scheduled event on the on-premises data gateway, such as a reboot or maintenance window. Enterprise gateways can be configured to reboot periodically for updates or health reasons, and if this coincides with the refresh schedule, the gateway will be unavailable, causing the refresh to fail. Transient errors or cloud maintenance would not produce a perfectly consistent daily failure at the same time.
Which TWO actions should you take to ensure that a Power BI report deployed to production is available to users even if the gateway is offline for maintenance?
Explanation: Creating a separate dataset in the cloud that caches the data (e.g., using a scheduled dataflow or a cloud-based dataset with Import mode) ensures that the report can still serve cached data from the Power BI service even when the on-premises gateway is offline for maintenance. This decouples report availability from gateway connectivity, as long as the cached data is refreshed before the maintenance window.
Which THREE steps should you perform to deploy a Power BI solution from development to production using deployment pipelines?
Explanation: Deployment pipeline rules allow you to modify dataset parameters (e.g., database server or database name) when content moves between pipeline stages, ensuring each stage connects to the appropriate data source without manual reconfiguration. This is a core feature of Power BI deployment pipelines to maintain environment-specific settings.
You review the dataset refresh history. The second refresh took 30 minutes and failed. What is the most likely reason for the failure?
Explanation: The second refresh took 30 minutes and failed, which strongly indicates the refresh exceeded the default 30-minute timeout limit configured in the on-premises data gateway. When a dataset refresh operation in Power BI runs longer than the gateway's timeout setting, the gateway terminates the connection, causing the refresh to fail. This is a common issue when refreshing large datasets or complex queries through a gateway.
