PL-300 Visualize and analyze the data Practice Question
This PL-300 practice question tests your understanding of visualize and analyze the data. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 have a Power BI report that uses a composite model with a DirectQuery source and an imported table. Users report that some visuals show incorrect totals when using measures that reference both sources. Which THREE conditions must be met to ensure correct results?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ensure relationships are defined with appropriate cardinality and cross-filter direction
Options A, D, and E are correct. Setting 'Assume Referential Integrity' (A) allows Power BI to optimize queries. Ensuring compatible relationships (D) is crucial for composite models. Using measures that aggregate correctly across storage modes (E) is necessary. Option B is incorrect because dual storage mode is not required. Option C is incorrect because query reduction does not fix incorrect totals.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Ensure relationships are defined with appropriate cardinality and cross-filter direction
Why this is correct
Proper relationships are essential for composite model accuracy.
Related concept
Static NAT maps one inside address to one outside address.
✗
Set both sources to Dual storage mode
Why it's wrong here
Dual mode is not required for composite models.
✓
Use measures that aggregate data at the appropriate granularity
Why this is correct
Measures must handle different storage modes correctly.
Related concept
Static NAT maps one inside address to one outside address.
✗
Enable 'Reduce queries' in report settings
Why it's wrong here
Query reduction minimizes queries but does not fix aggregation issues.
✓
Set 'Assume Referential Integrity' on relationships between sources
Why this is correct
This ensures optimized and correct cross-source queries.
Related concept
Static NAT maps one inside address to one outside address.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
What to study next
Got this wrong? Here's your next step.
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.
