AI-102 Plan and manage an Azure AI solution Practice Question
You are deploying a real-time translation service using Azure AI Translator. The solution must support automatic language detection and translation for customer chat conversations. Which pricing tier should you select to minimize costs while meeting the requirement?
⚠ Common exam trap
Many exam-takers assume the Free tier is sufficient for production workloads, overlooking its strict character and throughput limits, or they choose a higher tier like S2 or S3 thinking more capacity is always better, without considering cost optimization for the actual workload.
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
✓
Standard S1
The Standard S1 tier (D) is correct because it provides up to 1 million characters per month for translation and language detection, which is sufficient for typical customer chat workloads. The Free tier (F0) is limited to 2,000 characters per request and 2 million characters per month, which may be insufficient for production chat volumes. Higher tiers (S2, S3) offer increased throughput and character limits but incur higher costs, making S1 the most cost-effective choice that meets the requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Free (F0)
Why it's wrong here
Free tier has limited throughput (2M chars/month) and may not suffice.
- ✗
Standard S3
Why it's wrong here
S3 is for high throughput, overkill for chat.
- ✗
Standard S2
Why it's wrong here
S2 is more expensive and unnecessary for chat volumes.
- ✓
Standard S1
Why this is correct
S1 provides real-time translation with language detection at moderate cost.
