ARM Template: Multi-Service vs Single-Service Cognitive Services Account
This AI-102 practice question tests your understanding of implement computer vision solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure AI Services multi-service account
The ARM template snippet uses the 'CognitiveServices' resource type and sets 'kind' to 'CognitiveServices', which provisions a multi-service account that provides access to multiple Azure AI services (e.g., Language, Computer Vision, Translator) under a single endpoint and key. This is distinct from single-service accounts, which use specific 'kind' values like 'TextAnalytics' or 'ComputerVision'.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Azure AI Language
Why it's wrong here
Kind for Language is 'TextAnalytics'.
✗
Azure AI Computer Vision
Why it's wrong here
Kind for Computer Vision is 'ComputerVision'.
✓
Azure AI Services multi-service account
Why this is correct
The kind 'CognitiveServices' creates a multi-service account.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the 'CognitiveServices' kind (multi-service) with a specific single-service account, especially when the ARM template lacks explicit service-specific properties, leading them to pick a single-service option like Azure AI Language or Computer Vision.
Detailed technical explanation
How to think about this question
The multi-service Cognitive Services account uses a unified endpoint (e.g., https://<name>.cognitiveservices.azure.com/) and a single API key for all included services, but each service call must specify the correct service-specific path (e.g., /text/analytics/v3.0 for Language). This is useful for applications that need multiple AI capabilities without managing separate endpoints and keys, though billing is aggregated per service usage.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
