Question 513 of 988

Plan and manage an Azure AI solution →mediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is that the custom skill is missing the 'uri' property to specify the endpoint. Azure AI Search requires this property in a custom skill definition to provide the web API endpoint URL where the skill logic is hosted; without it, the service cannot route requests to your external function, causing the skill to fail silently or return errors. On the AI-102 exam, this scenario often appears in skillset JSON exhibits where a custom skill is defined with only a 'name' and 'context' but no 'uri', testing your ability to spot missing required properties. A common trap is confusing the 'uri' with the 'inputs' or 'outputs'—remember that the endpoint is the bridge between the skillset and your code. Memory tip: URI stands for Uniform Resource Identifier, and in custom skills, it’s the uniform way Azure finds your API.

AI-102 Plan and manage an Azure AI solution Practice Question

This AI-102 practice question tests your understanding of plan and manage an azure ai solution. 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.

Exhibit

Refer to the exhibit.
{
  "properties": {
    "displayName": "MySkill",
    "description": "Custom skill for translation",
    "context": "/document",
    "inputs": [
      {
        "name": "text",
        "source": "/document/content"
      }
    ],
    "outputs": [
      {
        "name": "translatedText",
        "targetName": "translated"
      }
    ]
  },
  "type": "Microsoft.Skills/CustomWebApiSkill"
}

You see the exhibit in an Azure AI Search skillset definition. The custom skill is not executing as expected. What is the most likely cause?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

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

Exhibit

      }
    ]
  },
  "type": "Microsoft.Skills/CustomWebApiSkill"
}

A
The skill is missing the 'uri' property to specify the endpoint
A custom web API skill must include 'uri' for the function URL.
B
The input source path is incorrect
Why wrong: '/document/content' is a typical path.
C
The JSON is malformed and will not parse
Why wrong: The JSON is valid.
D
The type should be 'Microsoft.Skills.Custom.WebApiSkill' with dots
Why wrong: The type is correct as 'Microsoft.Skills/CustomWebApiSkill'.

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

✓

The skill is missing the 'uri' property to specify the endpoint

The custom skill is not executing because the 'uri' property, which specifies the endpoint URL for the web API, is missing from the skill definition. Azure AI Search requires this property to route requests to the external service; without it, the skill cannot be invoked and will fail silently or return errors.

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 often focus on input/output paths or syntax errors, overlooking the fact that the 'uri' property is a required field for custom WebApiSkills, and its absence is a common oversight in skillset definitions.

Detailed technical explanation

How to think about this question

Under the hood, Azure AI Search skillsets are defined in JSON and validated against a schema; the 'uri' property is mandatory for the WebApiSkill type and must point to an HTTPS endpoint that returns a valid JSON response. In a real-world scenario, if the endpoint is omitted, the search service cannot resolve the skill's target, leading to a 'SkillExecutionError' with a message like 'The skill does not have a valid endpoint URI' in the indexer execution history.

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.
