- A
Move the report to a shared capacity and assign all users Pro licenses.
Why wrong: Shared capacity has lower performance limits and is not necessary; PPU works fine with DirectQuery.
- B
Change the report from DirectQuery to Import mode and configure scheduled refresh every 30 minutes.
Why wrong: DirectQuery cannot be changed to Import without redesign, and scheduled refresh does not apply to DirectQuery.
- C
Assign all users Premium Per User licenses to ensure they can view the report.
Why wrong: While PPU licenses would work, the issue is not licensing but gateway configuration; Free users cannot access the workspace.
- D
Switch the on-premises data gateway from personal mode to standard mode and add additional gateways to the cluster.
Standard mode gateways support multiple concurrent connections and improve performance for DirectQuery.
Quick Answer
The answer is to switch the on-premises data gateway from personal mode to standard mode and add additional gateways to the cluster. This is correct because DirectQuery mode sends live queries from Power BI to the on-premises SQL Server, and personal mode gateways are designed for single-user, single-session use, creating a bottleneck when 50 users hit the report simultaneously. Standard mode gateways support concurrent connections and can be grouped into a cluster to distribute query load, directly improving Power BI DirectQuery performance for many users. On the PL-900 exam, this scenario tests your understanding of gateway modes and scalability under load—a common trap is assuming personal mode works for teams, but it fails under multi-user concurrency. Remember that personal mode is for “one person, one session,” while standard mode is for “shared and scaled.” For a quick memory tip: think of personal mode as a single-lane road and standard mode as a multi-lane highway with tollbooths (gateways) you can add to handle traffic.
PL-900 Demonstrate the capabilities of Power BI Practice Question
This PL-900 practice question tests your understanding of demonstrate the capabilities of power bi. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are a data analyst at a manufacturing company that uses Microsoft 365 and Power BI. The company has a Power BI tenant with Free, Pro, and Premium Per User (PPU) licenses. Your team has created a Power BI report that visualizes production line efficiency from a SQL Server database on-premises. The report is published to a workspace assigned to a PPU capacity. You need to ensure that all 50 users in the production department can view the report on their mobile devices, with data refreshing every 30 minutes. The users have a mix of Free and Pro licenses. The report uses DirectQuery mode to the on-premises SQL Server. You have configured an on-premises data gateway in personal mode. Users report that the report is slow and sometimes fails to load. What should you do to improve performance and reliability while meeting the refresh requirement?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Switch the on-premises data gateway from personal mode to standard mode and add additional gateways to the cluster.
Option D is correct because the report uses DirectQuery mode, which requires a standard (on-premises data gateway) mode to handle concurrent queries efficiently. Personal mode is limited to a single user and cannot scale to support 50 users, causing slow performance and failures. Adding additional gateways to a standard mode cluster distributes the query load, improving reliability and performance while maintaining the 30-minute refresh requirement via DirectQuery.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Why it's wrong here
While PPU licenses would work, the issue is not licensing but gateway configuration; Free users cannot access the workspace.
- ✓
Switch the on-premises data gateway from personal mode to standard mode and add additional gateways to the cluster.
Why this is correct
Standard mode gateways support multiple concurrent connections and improve performance for DirectQuery.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often focus on licensing (Free vs. Pro vs. PPU) as the solution, overlooking the critical infrastructure issue of the gateway mode and cluster configuration for DirectQuery performance.
Detailed technical explanation
How to think about this question
DirectQuery mode sends queries directly to the on-premises SQL Server for each user interaction, so a personal mode gateway (designed for single-user testing) cannot handle concurrent requests from 50 users, leading to timeouts and failures. A standard mode gateway supports multiple users and can be part of a cluster for load balancing and high availability, which is essential for production workloads. The 30-minute refresh requirement is inherently met by DirectQuery as it queries live data, so no scheduled refresh is needed.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.

Same concept, more angles
1 more ways this is tested on PL-900
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A data analyst notices that a Power BI report takes a long time to load when filtering by a specific date range. The data source is a SQL Server view that contains millions of rows. What is the most effective way to improve performance?
medium- A.Create a calculated column for the date range filter
- ✓ B.Use DirectQuery and optimize the SQL view with indexes and filters
- C.Switch from DirectQuery to Import mode
- D.Hide unnecessary columns in the report
Why B: Option B is correct because the performance bottleneck is at the data source level—millions of rows in a SQL Server view. Using DirectQuery with optimized indexes and filters pushes query execution back to SQL Server, allowing it to leverage database-level performance features like index seeks and query plan caching. This reduces the amount of data transferred and processed in Power BI, directly addressing the root cause of slow filtering.
