The answer is to enable active learning in the project settings and periodically publish the updated knowledge base. This is correct because active learning in Azure AI Language’s custom question answering continuously monitors user queries that return low-confidence answers, then suggests alternative phrasings to the knowledge base editor, which directly improves custom question answering coverage with active learning by teaching the system to recognize paraphrased versions of existing questions. On the AI-102 exam, this scenario tests your understanding of how to handle ambiguous or reworded user input without retraining the entire model—a common trap is to assume you need more documents or additional training, but active learning is the built-in mechanism for this exact purpose. A helpful memory tip: think of active learning as a “suggestion box” for your FAQ bot—it collects user phrasing variations and lets you approve them, so the bot learns without manual rewriting.
AI-102 Practice Question: Implement natural language processing solutions
This AI-102 practice question tests your understanding of implement natural language processing solutions. 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 developing a chatbot for a retail company using Azure AI Language's custom question answering. The chatbot must provide answers from a knowledge base of 500 FAQ documents. Users often ask the same question in different wording, and the chatbot fails to return an answer for paraphrased queries. What is the most effective solution?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable active learning in the project settings and periodically publish the updated knowledge base.
Option C is correct because enabling active learning allows the system to learn from user interactions and suggest alternative phrasings. Option A is wrong because increasing document count doesn't help with paraphrasing. Option B is wrong because additional training is not a built-in feature; active learning is. Option D is wrong because Azure AI Bot Service is for bot hosting, not improving answer coverage.
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.
✗
Use Azure AI Bot Service's Direct Line Speech channel to improve accuracy.
Why it's wrong here
Direct Line Speech is for speech input/output, not for improving answer coverage.
✓
Enable active learning in the project settings and periodically publish the updated knowledge base.
Why this is correct
Active learning automatically suggests alternative phrasings based on user queries.
Related concept
Static NAT maps one inside address to one outside address.
✗
Increase the number of FAQ documents in the knowledge base.
Why it's wrong here
Adding more documents does not address paraphrasing issues.
✗
Manually add alternate question phrases to the knowledge base for each QnA pair.
Why it's wrong here
This is a workaround but not the most effective; active learning automates this.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
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 AI-102 NAT questions on configuration and troubleshooting.
