The correct answer is to use the Standard tier and allocate 10 capacity units (CUs). This configuration directly meets the requirement of scaling Azure AI Language question answering throughput with capacity units, as each CU provides a baseline of 100 requests per minute (RPM), so 10 CUs deliver exactly 1000 RPM with low latency. The Standard tier is essential because it supports multiple languages and enables the low-latency responses needed for FAQ-based solutions, while the Free tier lacks the throughput and scalability. On the AI-102 exam, this scenario tests your understanding of how capacity units map to request rates—a common trap is assuming you can scale with the Free tier or misallocating CUs by forgetting the 100 RPM per CU baseline. A useful memory tip is to think of each CU as a “100-RPM token,” so for any target throughput, simply divide by 100 to find the required CUs.
AI-102 Plan and manage an Azure AI solution Practice Question
This AI-102 practice question tests your understanding of plan and manage an azure ai solution. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
You are deploying a custom question-answering solution using Azure AI Language. The solution must support multiple languages and provide answers from a set of FAQ documents. You need to ensure that the service can handle up to 1000 requests per minute with low latency. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the Standard tier and allocate 10 capacity units (CUs).
Option B is correct because Azure AI Language's custom question-answering feature uses a Standard tier with capacity units (CUs) to handle throughput and latency. Each CU provides a baseline of 100 requests per minute (RPM), so 10 CUs deliver exactly 1000 RPM, meeting the requirement. The Standard tier also supports multiple languages and low-latency responses from FAQ documents.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use Azure AI Search with a basic tier and replicas.
Why it's wrong here
This is for search, not question answering.
✓
Use the Standard tier and allocate 10 capacity units (CUs).
Why this is correct
Standard tier with CUs provides the required throughput.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use the Free tier and enable autoscaling.
Why it's wrong here
Free tier is limited to 10 requests per minute.
✗
Deploy a dedicated endpoint with provisioned throughput of 1000 TPS.
Why it's wrong here
Custom question answering uses capacity units, not provisioned throughput.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing throughput units (requests per minute vs. per second) and assuming that Azure AI Search replicas or provisioned TPS from other services apply to Azure AI Language custom question-answering, when the correct scaling mechanism is capacity units (CUs) on the Standard tier.
Detailed technical explanation
How to think about this question
Azure AI Language custom question-answering uses a dedicated runtime where each capacity unit (CU) provides a guaranteed throughput of 100 requests per minute and a fixed latency SLA. Under the hood, the service distributes requests across multiple nodes based on the number of CUs, ensuring consistent performance even under load. In a real-world scenario, if you need to handle burst traffic, you can scale CUs up to 100 per project, but for a steady 1000 RPM, 10 CUs are the precise configuration.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
