- A
Reduce the number of epochs to match the number of GPUs
Why wrong: Epochs are not related to distributed training; reducing epochs underfits.
- B
Use the SageMaker distributed data parallelism library
The library automatically distributes data across GPUs.
- C
Manually split the training data into shards and upload to S3
Why wrong: Manual sharding is unnecessary; SageMaker handles data distribution.
- D
Configure the SageMaker estimator with a distribution parameter
The distribution parameter specifies the strategy (e.g., 'data_parallel').
- E
Set the instance count to 1 with a multi-GPU instance
Why wrong: Single instance, even with multiple GPUs, is not distributed training across instances.

MLA-C01 Practice Question: A data scientist is training a deep learning…
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 data scientist is training a deep learning model using SageMaker and wants to use distributed training across multiple GPUs to reduce training time. Which TWO actions should the scientist take to configure distributed training? (Select TWO.)
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 the SageMaker distributed data parallelism library
The SageMaker distributed data parallelism library (option B) automatically partitions training data and synchronizes gradients across multiple GPUs, reducing training time without manual data splitting. Configuring the SageMaker estimator with a distribution parameter (option D) enables this library by specifying the distribution strategy (e.g., 'torch_distributed' or 'tensorflow_distributed'), which is required to activate distributed training.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Why it's wrong here

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse single-instance multi-GPU training (option E) with true distributed training across multiple instances, or assume manual data sharding (option C) is required when SageMaker automates it.
Detailed technical explanation
How to think about this question
SageMaker's distributed data parallelism library uses AllReduce (e.g., NCCL-based ring all-reduce) to synchronize gradients across GPUs, scaling efficiently by overlapping communication with computation. Under the hood, it automatically shards the training dataset using a shard index assigned to each GPU, ensuring each GPU processes a unique subset of data per batch. In real-world scenarios, using this library with the distribution parameter set to 'torch_distributed' or 'tensorflow_distributed' can achieve near-linear speedup when training large models like BERT or ResNet on multiple p3.16xlarge instances.
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 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.
