Correct answer & explanation
✓
Enable SageMaker Managed Spot Training
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 on-demand instances for reliability
Why it's wrong here
On-demand is more expensive; spot is suitable for fault-tolerant jobs.
- ✓
Enable SageMaker Managed Spot Training
Why this is correct
Managed Spot Training automates the use of spot instances and handles interruptions.
- ✓
Use spot instances for the training jobs
Why this is correct
Spot instances offer significant cost savings, up to 90%.
- ✗
Use ml.c5 instances instead of ml.p3
Why it's wrong here
c5 instances are CPU-only and may not be suitable for GPU-required training.
- ✗
Increase the number of parallel training jobs
Why it's wrong here
Increasing parallelism may increase overall cost, not reduce it.

Same concept, more angles
2 more ways this is tested on MLA-C01
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A machine learning engineer needs to reduce costs when training a large model on SageMaker. They are willing to accept potential interruptions and have checkpointing enabled. Which instance purchasing option should they use?
easy- ✓ A.Spot instances
- B.Reserved instances
- C.Dedicated hosts
- D.On-demand instances
Why A: Spot instances offer significant cost savings (up to 60-90%) compared to on-demand, but can be reclaimed by AWS with a 2-minute notice. Checkpointing allows resuming training from the last saved state, making spot instances suitable.
Variation 2. A machine learning engineer wants to reduce training costs by using excess EC2 capacity. Which instance purchasing option should they choose for SageMaker training jobs?
easy- A.Reserved Instances
- B.On-Demand Instances
- C.Dedicated Instances
- ✓ D.Spot Instances
