- A
Switch to the free tier to access all features.
Why wrong: The free tier has limited features and may not support all required features; also the issue is regional, not tier-based.
- B
Upgrade the Language resource to the S1 tier to enable all features.
Why wrong: The S0 tier already supports key phrase extraction and sentiment analysis; the issue is not the tier.
- C
Verify regional availability of the features and recreate the Language resource in a supported region if necessary.
Certain features may not be available in all regions; checking regional availability and recreating the resource in a supported region resolves the issue.
- D
Regenerate the API key and update the application code.
Why wrong: Regenerating the key does not affect feature availability.
Quick Answer
The correct answer is to verify regional availability of the features and recreate the Language resource in a supported region if necessary. This is because the 403 error signals an authorization failure tied to regional feature support, not a subscription tier or key issue—while PII detection may have broader regional availability, key phrase extraction and sentiment analysis are not guaranteed in every Azure region, and East US may lack support for these specific capabilities. On the AI-102 exam, this scenario tests your understanding that Azure AI Language features have distinct regional footprints, and a common trap is assuming all features are available wherever the resource is provisioned. Remember that compliance requirements, like keeping data within the United States geography, further narrow your region choices to those like West US or South Central US that support all three features. A helpful memory tip: “403 means region lock—check the feature map before you deploy the stack.”
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.
A healthcare company is developing a solution to analyze patient feedback using Azure AI Language. The solution must extract key phrases, detect sentiment, and identify personally identifiable information (PII) such as patient names and medical record numbers from unstructured text. The company has strict compliance requirements: all text processing must occur within the United States region, and no data may leave the Azure geography. The development team has provisioned a Language resource in the East US region and has been testing the solution. During testing, the team notices that the PII detection feature is returning results, but the key phrase extraction and sentiment analysis are failing with a 403 error. The error message indicates that the resource is not allowed to access these features. The team has verified that the resource is in the S0 tier. What should the team do to resolve the issue?
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
Verify regional availability of the features and recreate the Language resource in a supported region if necessary.
The 403 error indicates an authorization or regional availability issue, not a tier or key problem. Key phrase extraction and sentiment analysis are available in all regions that support the Language service, but PII detection may have broader regional support. The team must verify that the East US region supports all three features; if not, they need to recreate the resource in a supported region like West US or South Central US to ensure compliance with the United States geography requirement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume a 403 error always means an authentication or authorization issue (like an invalid key or insufficient tier), when in fact it can indicate that the requested feature is not available in the resource's region, a subtle but critical distinction in Azure AI services.
Trap categories for this question
Keyword trap
The S0 tier already supports key phrase extraction and sentiment analysis; the issue is not the tier.
Detailed technical explanation
How to think about this question
Azure AI Language features like key phrase extraction and sentiment analysis are deployed per region, and some regions may not support all capabilities due to compliance or infrastructure constraints. The 403 error often surfaces when the API endpoint returns a 'NotAllowed' status because the feature is not enabled for that regional resource, even though the resource exists. In practice, teams should use the Azure portal's 'Features' blade or the REST API's regional availability list to confirm which capabilities are supported in their chosen region before provisioning.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
