RLS: R-estrict L-evel S-ecurity. Remember 'Roles' are defined in 'Desktop', 'Users' are assigned in the 'Service'.

Module 4: Deploying and Maintaining Power BI Assets

Exam tip

Implementing Row-Level Security (RLS) for Data Access

The exam frequently tests your understanding of how RLS interacts with different user types and how to assign users to roles in the Power BI Service. Pay close attention to the 'Security' section under dataset settings. Remember that RLS filters data, it doesn't hide entire visuals or pages.

Module 4: Deploying and Maintaining Power BI Assets

Common mistake

Implementing Row-Level Security (RLS) for Data Access

Forgetting to assign users or security groups to the RLS roles in the Power BI Service after publishing the report.

Module 4: Deploying and Maintaining Power BI Assets

Common mistake

Implementing Row-Level Security (RLS) for Data Access

Using static filter values in DAX expressions when dynamic filtering (e.g., using USERPRINCIPALNAME()) is required, leading to incorrect access.

Module 4: Deploying and Maintaining Power BI Assets

Common mistake

Implementing Row-Level Security (RLS) for Data Access

Not thoroughly testing RLS in Power BI Desktop using 'View as roles' before publishing, resulting in unintended data exposure or access issues.

Key term

Publish

The act of uploading content from Desktop to the Service.

Module 4: Deploying and Maintaining Power BI Assets

Memory trick

Deploying and Publishing Power BI Content

Think 'P-W-A': Publish to Workspace, then create an App. PWA for Power BI!

Module 4: Deploying and Maintaining Power BI Assets

Exam tip

Deploying and Publishing Power BI Content

The exam often tests the appropriate use case for 'My Workspace' versus a shared workspace, and when to use a Power BI app. Memorize that apps are for broad, read-only distribution of finalized content.

Module 4: Deploying and Maintaining Power BI Assets

Common mistake

Deploying and Publishing Power BI Content

Publishing sensitive or unfinished content directly to a broad audience without using an app or proper workspace permissions.

Module 4: Deploying and Maintaining Power BI Assets

Common mistake

Deploying and Publishing Power BI Content

Forgetting to configure data source credentials for scheduled refresh in the Power BI service, leading to stale data.

Module 4: Deploying and Maintaining Power BI Assets

Common mistake

Deploying and Publishing Power BI Content

Sharing content by giving direct workspace access to all users instead of using a Power BI app for consumption.

Module 4: Deploying and Maintaining Power BI Assets

Common mistake

Deploying and Publishing Power BI Content

Not testing reports and dashboards thoroughly in the Power BI service environment before broad distribution.

Module 4: Deploying and Maintaining Power BI Assets

Key term

Data Staleness

When data displayed in reports is not current with the source system.

Module 4: Deploying and Maintaining Power BI Assets

Memory trick

Validating and Monitoring Deployed Content

To remember the monitoring tools: R.U.A. - Refresh history for Updates, Usage metrics for Activity, Audit logs for Accountability.

Module 4: Deploying and Maintaining Power BI Assets

Exam tip

Validating and Monitoring Deployed Content

The exam often tests your understanding of where to find specific monitoring information. Remember that 'Refresh history' is for dataset refresh status, 'Usage metrics reports' are for report/dashboard interaction and performance, and 'Audit logs' are for security and compliance activities, typically accessed via the Microsoft 365 compliance center.

Module 4: Deploying and Maintaining Power BI Assets

Common mistake

Validating and Monitoring Deployed Content

Ignoring refresh history: Failing to regularly check refresh history can lead to unnoticed data staleness and incorrect business decisions.

Module 4: Deploying and Maintaining Power BI Assets

Common mistake

Validating and Monitoring Deployed Content

Skipping UAT: Deploying content without user acceptance testing can result in reports that don't meet business needs or contain subtle errors.

Module 4: Deploying and Maintaining Power BI Assets

Common mistake

Validating and Monitoring Deployed Content

Not using Performance Analyzer: Guessing at performance issues instead of using Performance Analyzer leads to inefficient troubleshooting and wasted effort.

Module 4: Deploying and Maintaining Power BI Assets

Exam tip

Understanding Power BI Service Administration

The exam frequently tests your understanding of which administrative roles can perform specific actions (e.g., 'Who can enable/disable publishing to web?') and the purpose of key sections within the Admin portal. Memorize the primary responsibilities of the Power BI Service Administrator.

Module 4: Deploying and Maintaining Power BI Assets
