Which Azure resource gives a single endpoint for Decision and Language APIs?

Select the appropriate Microsoft Foundry Services Plan, create and deploy a Microsoft Foundry Service

Short answer

C Create a multi-service Azure Cognitive Services (Azure AI services) resource so the Language and Decision APIs share one endpoint and credential.

Question

You are developing an app that will use the Decision and Language APIs. You need to provision resources for the app. The solution must ensure that each service is accessed by using a single endpoint and credential. Which type of resource should you create?
  1. Language
  2. Speech
  3. Azure Cognitive Services Correct Answer
  4. Content Moderator

Key Takeaways

Tests whether you know the Azure AI services multi-service resource unifies access to Language and Decision under one endpoint and credential, versus single-service resources that each require their own.

A multi-service Azure Cognitive Services (now Azure AI services) resource provides one endpoint and one key across multiple APIs, including Language and Decision. This page establishes that option C is the resource type that satisfies the AI-102 single-endpoint and single-credential requirement.

Common mistake: Choosing Language (A) because the app uses the Language API; a Language resource is single-service, so the Decision API would need a separate endpoint and credential.

Expert Analysis

Why the Answer Is Correct

A multi-service Azure Cognitive Services resource — now branded Azure AI services in the portal — is explicitly designed to expose multiple APIs, including Language and Decision, through one endpoint and one key. That directly satisfies the stem's requirement that each service be accessed "by using a single endpoint and credential." The single-service resource types (Language, Speech) each bind to one service and cannot host both APIs. Therefore C is the only option that matches the required provisioning model.

Why the Other Options Are Wrong

A Language resource is scoped to the Language service only, so it cannot provide a shared endpoint and credential for the Decision API. A Speech resource similarly covers speech capabilities only and cannot serve Language and Decision requests. Content Moderator is a specific content-safety service, not a multi-service container for Language and Decision. Selecting any of these would force separate endpoints and credentials, violating the requirement.

Community Comment Notes

Learners overwhelmingly selected C, with GHill1982 noting that a multi-service resource provides "a single key and endpoint." nanaw770 correctly points out the naming update to "Azure AI," and chrillelundmark notes the question is deprecated because the old Decision API reference is hard to find. Even with the rebrand, the architectural intent remains: choose the multi-service Azure AI services resource when the scenario demands one endpoint and key across multiple APIs.

Exam Strategy

Anchor on the phrase "single endpoint and credential" — it is the tell for a multi-service Azure AI services resource. Do not be distracted by the individual API names in the stem, because the requirement is cross-service access, not one API. If the exam still says Azure Cognitive Services, treat it as the multi-service resource.

Frequently Asked Questions

Why is a Language resource not enough for Decision and Language APIs?

A Language resource exposes only the Language service, so it cannot also host the Decision API under the same endpoint and credential. The multi-service resource is required to combine both APIs.

Does Azure Cognitive Services still exist under that name?

The portal now brands it Azure AI services, but the multi-service resource still provides a single key and endpoint for multiple Azure AI APIs.

    C is right answer, but now this service name changed "Azure AI".
  2. chrillelundmark 👍 3 Answered C
    This question is depricated. Azure Cognitive services is now Azure AI services. I can't find any info about the Decision API but Language API resides within the new AI Services. So for the options: A) Part of Azure AI Services B) Part of Azure AI Services C) Renamed to Azure AI Services D) Part of Azure AI Services, but renamed to Content Safety
  3. GHill1982 👍 3 Answered C
    A Cognitive Services multi-service resource allows you to access multiple Azure AI services with a single key and endpoint.
  4. Murtuza 👍 1 Answered C
    The correct answer is C. Azure Cognitive Services. When you create an Azure Cognitive Services resource, you get access to a suite of services and APIs, including the Decision and Language APIs, under a single endpoint and credential. This simplifies the management of these services and enhances security by reducing the number of credentials you need to manage. Other options like Language, Speech, and Content Moderator are individual services within Azure Cognitive Services. They do not provide a single endpoint and credential for accessing multiple services. Therefore, they do not meet the requirement specified in the question
