PL-900 Practice Question: Demonstrate the capabilities of Microsoft Copilot Studio
You are a Power Platform administrator for Contoso Ltd. The company uses Microsoft Copilot Studio to build a customer support copilot. The copilot has several topics for common issues. Recently, users report that when they ask about "refund policy," the copilot responds with unrelated information about shipping. You review the copilot and find that: - There is a topic called "Refund Policy" with trigger phrases: "refund policy", "return policy", "money back". - There is a topic called "Shipping Information" with trigger phrases: "shipping", "delivery", "refund policy". - Both topics are active and have similar confidence thresholds. - The "Shipping Information" topic was created last week by a new team member. - The "Fallback" topic responds with "I'm sorry, I didn't understand."
You need to ensure that when users say "refund policy," the correct topic is triggered. You want to minimize changes to existing configurations. What should you do?
⚠ Common exam trap
Watch out — candidates often think reordering topics (Option B) controls trigger priority, but in Copilot Studio, topic order only affects fallback and system topics, not custom topic matching, which is purely based on NLU confidence scoring.
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
✓
Remove the trigger phrase "refund policy" from the "Shipping Information" topic.
Removing the trigger phrase 'refund policy' from the 'Shipping Information' topic eliminates the conflicting trigger that causes the copilot to match the wrong topic. In Microsoft Copilot Studio, when multiple topics share the same trigger phrase and have similar confidence thresholds, the system may select the wrong topic based on recency or other scoring factors. By removing the duplicate phrase from the newer topic, the 'Refund Policy' topic becomes the only match for that phrase, ensuring the correct response.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Remove the trigger phrase "refund policy" from the "Shipping Information" topic.
Why this is correct
Removing the duplicate phrase eliminates the conflict while preserving the shipping topic.
- ✗
Reorder topics so that "Refund Policy" appears before "Shipping Information" in the topic list.
Why it's wrong here
Topic order does not affect trigger phrase matching; all topics with matching phrases compete.
- ✗
Lower the trigger confidence threshold for the "Refund Policy" topic to 0.7.
Why it's wrong here
Lowering threshold may increase false positives and not resolve the conflict.
- ✗
Delete the "Shipping Information" topic and recreate it without the phrase "refund policy."
Why it's wrong here
Deleting the entire topic is unnecessary; only the trigger phrase needs removal.
