- A
Increase the batch size for inference.
Why wrong: Larger batch sizes can increase latency due to longer processing time per request.
- B
Use a smaller instance type to reduce inference time.
Why wrong: Smaller instances may have less compute power, increasing latency.
- C
Use SageMaker Inference Recommender to test different instance types and optimizations.
Inference Recommender helps find the optimal configuration for low latency.
- D
Enable SageMaker Model Monitor to detect performance issues.
Why wrong: Model Monitor is for data and model drift, not latency optimization.

This MLA-C01 practice question tests your understanding of mla-c01 exam topics. 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.
A company deploys a model on Amazon SageMaker for real-time inference. The inference latency is too high. The model is a large deep learning model. The company wants to reduce latency without significantly impacting accuracy. Which approach should the company consider?
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
✓
Use SageMaker Inference Recommender to test different instance types and optimizations.
SageMaker Inference Recommender is designed specifically to automate load testing and benchmarking across various instance types and model optimizations (e.g., Elastic Inference, GPU acceleration, serialization formats). It provides latency and throughput metrics to identify the optimal configuration for reducing inference latency while maintaining accuracy, making it the correct choice for a large deep learning model with high latency.
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.
- ✗
Increase the batch size for inference.
Why it's wrong here
Larger batch sizes can increase latency due to longer processing time per request.
- ✗
Use a smaller instance type to reduce inference time.
Why it's wrong here
Smaller instances may have less compute power, increasing latency.
- ✓
Use SageMaker Inference Recommender to test different instance types and optimizations.
Why this is correct
Inference Recommender helps find the optimal configuration for low latency.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Enable SageMaker Model Monitor to detect performance issues.
Why it's wrong here
Model Monitor is for data and model drift, not latency optimization.
Common exam traps
Common exam trap: answer the scenario, not the keyword
AWS often tests the misconception that reducing instance size or increasing batch size directly reduces latency, when in fact these actions typically increase latency or degrade throughput for real-time inference.
Detailed technical explanation
How to think about this question
Inference Recommender uses a combination of SageMaker's built-in algorithms and custom load tests to evaluate instance types (e.g., ml.c5, ml.p3) and optimizations like SageMaker Neo for model compilation or Elastic Inference for cost-effective GPU acceleration. It generates a recommendation report with latency percentiles (p50, p90, p99) and throughput, allowing you to balance latency and cost without manual trial-and-error. For large deep learning models, this is critical because naive instance selection often leads to either under-provisioning (high latency) or over-provisioning (high cost).
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
