The answer is that a missing or incorrect output field mapping is the most likely cause of the enrichment pipeline failure. In Azure AI Search, each skill within a skillset produces named outputs that must be explicitly mapped to fields in the search index via output field mappings; without this mapping, the pipeline has no destination for the enriched data, causing it to fail, particularly with larger documents over 5000 characters that generate more complex output. On the AI-102 exam, this tests your understanding of how the enrichment pipeline processes data flow from skills to the index, often appearing in troubleshooting scenarios where the pipeline silently fails. A common trap is assuming the pipeline automatically maps skill outputs, but it does not—every output requires an explicit mapping. Remember the mnemonic: "No map, no trap"—without the mapping, the pipeline cannot store the enriched data and will fail.
AI-102 Practice Question: Implement knowledge mining and document intelligence solutions
This AI-102 practice question tests your understanding of implement knowledge mining and document intelligence 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 company uses this skillset in an Azure AI Search enrichment pipeline. They notice that the enrichment pipeline fails when processing a document larger than 5000 characters. What is the most likely cause?

Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

Correct answer & explanation
✓
The output field mapping is missing or incorrect
The enrichment pipeline fails because the output field mapping is missing or incorrect. When a skillset processes documents, the output of each skill must be explicitly mapped to an index field; if this mapping is absent or misconfigured, the pipeline cannot store the enriched data and fails, especially for larger documents that produce more output data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The maximum page length is too small
Why it's wrong here
The skill splits documents into pages; it does not fail due to size.
✗
The default language code is not supported
Why it's wrong here
'en' is a supported language code.
✗
The text split mode should be 'sentences'
Why it's wrong here
'pages' is a valid split mode.
✓
The output field mapping is missing or incorrect
Why this is correct
The output 'pages' must be mapped to a collection field in the index.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often attribute pipeline failures to text splitting or language settings, but the real issue is the missing output field mapping, which is a common misconfiguration in skillset definitions.
Detailed technical explanation
How to think about this question
In Azure AI Search, each skill in a skillset produces outputs that must be mapped to index fields via outputFieldMappings. If a mapping is missing, the pipeline cannot write the enriched data, and the indexer fails with an error like 'Output field mapping not found'. This is particularly common when processing large documents because the volume of generated data amplifies the impact of missing mappings, causing the pipeline to hit internal limits or timeouts.

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 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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
