Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set up auto-scaling with a target tracking policy based on the recommended metric
SageMaker Inference Recommender provides a baseline configuration. To optimize costs, they should apply auto-scaling with a target tracking policy based on the recommended metric, such as invocation count or latency.
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 the recommended configuration without changes, as it is already optimal
Why it's wrong here
The recommendation is static; traffic may vary, so scaling is needed.
- ✗
Purchase a Savings Plan for the recommended instance type to reduce hourly cost
Why it's wrong here
Savings Plans reduce cost per instance hour, but do not address over-provisioning; auto-scaling is needed first.
- ✓
Set up auto-scaling with a target tracking policy based on the recommended metric
Why this is correct
Auto-scaling adjusts capacity to demand, minimizing cost while meeting performance.
- ✗
Manually adjust the instance count daily based on observed traffic
Why it's wrong here
Manual adjustment is not automated and may not react quickly.
