AI-102 Plan and manage an Azure AI solution Practice Question
Your Azure AI Search solution uses a custom skill to call an external API. The skill runs locally but fails when deployed to the search service. What is the most likely cause?
⚠ Common exam trap
Many candidates assume the skill logic is faulty (input/output mappings) rather than recognizing that the network connectivity and HTTPS requirement is the fundamental difference between local testing and cloud execution.

Correct answer & explanation
✓
The skill endpoint is not publicly accessible via HTTPS.
When a custom skill runs locally but fails after deployment to Azure AI Search, the most common cause is that the skill's endpoint is not publicly accessible via HTTPS. Azure AI Search indexers execute skills in the cloud and must be able to reach the external API over the internet using a secure HTTPS connection; localhost or HTTP endpoints will fail.
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's output field mappings are missing.
Why it's wrong here
Would result in missing enriched fields, not skill execution failure.
- ✗
The skill's input field mappings are incorrect.
Why it's wrong here
Would cause skill execution errors but not a connection issue.
- ✗
The indexer name is misspelled in the skillset.
Why it's wrong here
Would cause indexer start failure, not skill failure.
- ✓
The skill endpoint is not publicly accessible via HTTPS.
Why this is correct
The search service cannot reach a local or non-HTTPS endpoint.
