AI-102 Plan and manage an Azure AI solution Practice Question
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?
⚠ Common exam trap
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.
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.
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 skill is missing the 'uri' property to specify the endpoint
Why this is correct
A custom web API skill must include 'uri' for the function URL.
- ✗
The input source path is incorrect
Why it's wrong here
'/document/content' is a typical path.
- ✗
The JSON is malformed and will not parse
Why it's wrong here
The JSON is valid.
- ✗
The type should be 'Microsoft.Skills.Custom.WebApiSkill' with dots
Why it's wrong here
The correct @odata.type for a custom Web API skill is 'Microsoft.Skills.Custom.WebApiSkill' (with dots), not with slashes. Option D incorrectly states the type should be with dots, but it actually is the correct format. However, the issue in the question is the missing 'uri' property, not the type format.
