A developer is using Azure OpenAI Service to generate product descriptions from technical specifications. The generated descriptions sometimes include plausible-sounding but incorrect details (hallucinations). The developer wants to ensure the model's responses are strictly based on the provided product data and does not add any external or invented information. Which approach should the developer use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Use Azure OpenAI On Your Data to connect to a product database so the model retrieves and references only the provided specifications.
Azure OpenAI On Your Data grounds the model on your data, making it more likely to generate responses based solely on the provided facts, thus reducing hallucinations.
B
Distractor review
Increase the frequency penalty to discourage the model from repeating common phrases.
Frequency penalty affects repetition of tokens, not the factual accuracy or hallucination of the content.
C
Distractor review
Decrease the temperature to 0 so the model always picks the most likely next token, making it more predictable.
While low temperature reduces randomness, the model can still generate hallucinated content because it is not constrained to the provided data.
D
Distractor review
Enable content filtering to block any outputs that contain harmful or biased language.
Content filtering is for safety (e.g., hate speech, violence) and does not address factual accuracy or anchor the model to specific data.
Common exam trap
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.
Technical deep dive
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.

Question 2
A developer is building a customer support chatbot using Azure OpenAI. The chatbot should never reveal its system instructions or internal configuration. The developer wants to add a rule at the beginning of the conversation to prevent prompt injection attacks. Which technique should they use?
Question 3
A developer is using Azure OpenAI with GPT-4 to build a chatbot that answers legal questions based on a company's internal policy documents. The developer wants the model's responses to be maximally deterministic and factual, avoiding any creative or speculative language. Which parameter should the developer set to the lowest possible value in the API call?
Question 4
A developer is using Azure OpenAI to generate creative product descriptions. The outputs are often repetitive and lack variety. The developer wants to increase the diversity of the generated text while still keeping it coherent. Which parameter should the developer increase?
Question 5
A developer is using Azure OpenAI Service to generate product descriptions. They want the output to be highly focused and deterministic, with less randomness. Which parameter should they decrease?
Question 6
A developer is using Azure OpenAI Service to classify customer support tickets into categories such as 'Billing', 'Technical Issue', and 'Account Management'. The developer provides three labeled examples for each category in the prompt to improve the model's accuracy. What technique is the developer applying?
FAQ
Questions learners often ask
What does this AI-900 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Use Azure OpenAI On Your Data to connect to a product database so the model retrieves and references only the provided specifications. — The correct approach is to use Azure OpenAI On Your Data, which allows the model to ground its responses by retrieving relevant information from a provided data source (e.g., a product database or documents). This significantly reduces hallucinations by anchoring the output to the supplied content. Increasing the frequency penalty (A) reduces repetition but does not prevent hallucination. Decreasing the temperature (B) makes the model more deterministic and less creative, but it can still generate unsupported facts. Enabling content filtering (D) blocks harmful or offensive content but does not ensure factual accuracy based on the given specs.
