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. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.

Exhibit

Refer to the exhibit.
{
  "value": [
    {
      "name": "myindexer",
      "status": "running",
      "lastResult": {
        "status": "success",
        "errorCount": 0,
        "warningCount": 5
      }
    }
  ]
}

You run the Azure CLI command 'az search indexer list --search-service mysearch --query "[].{name:name, status:status, lastResult:lastResult}"' and get the above output. Your indexer shows 5 warnings. What should you do to investigate the warnings?

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

✓

Run 'az search indexer show --name myindexer' and review the 'warnings' array in the output.

The 'az search indexer list' command with the query you used returns a summary of indexer status and last result, but it does not include the detailed 'warnings' array. To investigate the 5 warnings, you need to use 'az search indexer show --name myindexer', which returns the full indexer execution history, including a 'warnings' array that lists each warning with its message and details. This allows you to understand the nature of each warning and take corrective action if needed.

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.

  • ✗

    Run 'az search indexer run --name myindexer' to trigger a new run.

    Why it's wrong here

    Running again may produce the same warnings; you need to see the existing warnings.

  • ✓

    Run 'az search indexer show --name myindexer' and review the 'warnings' array in the output.

    Why this is correct

    The indexer show command returns detailed execution history including warnings.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Ignore the warnings because they are not errors.

    Why it's wrong here

    Warnings may indicate data quality issues that should be investigated.

  • ✗

    Run 'az search indexer reset --name myindexer' to reset the indexer.

    Why it's wrong here

    Resetting re-runs the indexer but does not show warnings; warnings are per execution.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates assume the 'list' command provides full details, but it only returns a filtered projection; the 'show' command is required to access the nested 'warnings' array, which is a common pattern in Azure CLI where list commands return summaries and show commands return full objects.

Trap categories for this question

  • Command / output trap

    Resetting re-runs the indexer but does not show warnings; warnings are per execution.

Detailed technical explanation

How to think about this question

Azure Cognitive Search indexers maintain a detailed execution history that includes a 'warnings' array at the top level of the indexer's JSON output. Each warning object contains a 'message' string and a 'details' object that can include the specific document key, field name, and error code. Warnings often arise from type mismatches between source data and the index schema (e.g., a string field receiving an integer), or from document-level issues like exceeding the maximum document size (16 MB per document). Reviewing these warnings is critical for maintaining data integrity and ensuring that all documents are correctly indexed.

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 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.
