AI-102 Practice Question: Implement natural language processing solutions

Exhibit

{
  "error": {
    "code": "403",
    "message": "Access denied due to invalid subscription key. Make sure to provide a valid key for an active subscription.",
    "innererror": {
      "code": "InvalidSubscriptionKey",
      "message": "The provided subscription key is not valid for the Cognitive Services resource."
    }
  }
}

Refer to the exhibit. You receive this error when calling an Azure Cognitive Services API. What is the most likely cause?

⚠ Common exam trap

A common mix-up: candidates confuse region mismatch with key validity, but Azure Cognitive Services keys are not region-bound—they are resource-bound, so the error is about the key not matching the resource, not the region.

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 subscription key is not valid for this Cognitive Services resource.

The error indicates that the subscription key provided is not associated with the Cognitive Services resource being accessed. In Azure Cognitive Services, each resource has a unique set of keys, and using a key from a different resource (even in the same region) will result in a 401 Unauthorized error with this specific message. Option D is correct because the key must match the resource's endpoint exactly.

Keys are not region-specific; they are tied to the resource.
