The answer is that the relationship between the Shipments and City tables is based on OriginCity, but the table visual is displaying DestinationCity, so the filter from the map does not apply. When you click a bubble on the map, Power BI sends a filter on the City dimension table, but this filter only propagates to the Shipments table along the active relationship, which is defined on OriginCity. If the table visual shows DestinationCity, that column is not linked to the filtered City table, so cross-filtering from map to table fails despite being enabled. This scenario tests your understanding of how model relationships and filter propagation work in Power BI, a key concept for the PL-300 exam. A common trap is assuming any city field will filter automatically, but the relationship direction and column match are critical. Memory tip: always verify that the column used in the visual matches the relationship key—if the map filters OriginCity, your table must show OriginCity, not DestinationCity.
PL-300 Visualize and analyze the data Practice Question
This PL-300 practice question tests your understanding of visualize and analyze the data. 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 Power BI consultant for a logistics company. The company has a semantic model with a 'Shipments' fact table (containing 'ShipmentID', 'Date', 'OriginCity', 'DestinationCity', 'Weight', 'Cost') and 'City' dimension table (with 'City', 'Region', 'Country'). The company wants a report that displays a map visual with bubbles sized by total shipment weight, and a slicer to select a region. Additionally, they want to be able to click on a bubble (city) and see a table of shipments from that city. You have implemented a map visual using the 'City' field and a table visual. When you click on a bubble, the table does not filter to show only shipments from that city. You have confirmed that cross-filtering is enabled. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
The map visual does not have a legend field, so clicking does not generate a filter.
Why wrong: Clicking a bubble still sends a filter on the location field.
B
The table visual has a filter that prevents cross-filtering.
Why wrong: No filter is mentioned.
C
The relationship between Shipments and City is based on OriginCity, but the table shows DestinationCity, so the filter does not apply.
The filter from the map applies to the City dimension, but the table uses a different field (DestinationCity) that is not related to the same City table.
D
The region slicer is interfering with the cross-filtering.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The relationship between Shipments and City is based on OriginCity, but the table shows DestinationCity, so the filter does not apply.
The map visual uses the 'City' field from the City dimension table. When you click a bubble, it sends a filter on the City table. However, the table visual likely uses fields from the Shipments table (e.g., ShipmentID, DestinationCity). If the relationship between Shipments and City is based on OriginCity, and the table is showing DestinationCity, the filter from the map (on City) may not propagate correctly because the relationship is on OriginCity, not DestinationCity. Option D is correct. Option A is incorrect because the slicer is not the issue. Option B is incorrect because the map should have a legend if needed. Option C is incorrect because the table might have many rows but filtering should work.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Related concept
Static NAT maps one inside address to one outside address.
✗
The region slicer is interfering with the cross-filtering.
Why it's wrong here
Slicers do not block cross-filtering.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PL-300 NAT questions on configuration and troubleshooting.

Variation 1. A company wants to create a Power BI report that shows sales performance by region. The data contains a table 'Sales' with columns: Date, Amount, RegionID, and ProductID. They also have a 'Regions' table with RegionID and RegionName. They want to display a matrix visual with RegionName on rows and Year on columns, with the sum of Amount as values. However, the report displays only 'RegionID' instead of 'RegionName'. What is the most likely cause?
hard
A.The relationship is configured as many-to-many.
B.The relationship direction is set to Both.
C.The RegionID column in the Sales table is hidden.
✓ D.There is no active relationship between the Sales and Regions tables.
Why D: Option D is correct because if there is no active relationship between the Sales and Regions tables, Power BI cannot use the RegionName from the Regions table to filter or group the Sales data. Instead, it defaults to displaying the RegionID from the Sales table, which is the only related field available in the visual. An active relationship must exist between the two tables on the RegionID columns for RegionName to appear in the matrix.
