- A
Use Azure AI Document Intelligence instead of a custom skill
Why wrong: Not an alternative for custom logic.
- B
Increase the function timeout and ensure the function is in the same region as the search service
Longer timeout accommodates large documents.
- C
Set the function timeout to the maximum of 24 hours
Why wrong: Unreasonable; better to optimize the function.
- D
Move the custom skill to Azure AI Language custom entity recognition
Why wrong: Does not address timeout.

AI-102 Practice Question: Implement knowledge mining and information extraction solutions
This AI-102 practice question tests your understanding of implement knowledge mining and information extraction solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Your knowledge mining pipeline uses Azure AI Search with a custom skillset that calls an Azure Function. The function sometimes times out for large documents. What is the best way to handle this?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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
✓
Increase the function timeout and ensure the function is in the same region as the search service
Option B is correct because increasing the function timeout (up to the Azure Functions maximum of 10 minutes for the Consumption plan or 30 minutes for the Premium plan) and ensuring the function is in the same region as the search service reduces latency and network overhead, directly addressing timeout issues for large documents. Azure AI Search custom skills must complete within the function's configured timeout, and regional colocation minimizes cross-region data transfer delays.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Does not address timeout.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think increasing the timeout to an arbitrarily high value (like 24 hours) is possible, but Azure Functions enforce strict maximum timeout limits depending on the hosting plan, and the correct approach is to work within those limits while optimizing performance through regional colocation.
Detailed technical explanation
How to think about this question
Under the hood, Azure AI Search custom skills execute via HTTP requests to the Azure Function endpoint, and the search service waits for a response within the function's configured timeout. For large documents, the function may need to process data in chunks or use async patterns (e.g., Durable Functions) to avoid timeouts, but the immediate fix is to increase the timeout and colocate resources to reduce latency. In real-world scenarios, a function processing multi-page PDFs or large JSON payloads often hits the default 5-minute timeout, so bumping it to 10 minutes and placing the function in the same region as the search service (e.g., both in East US) can resolve intermittent failures.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
