Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Spot instances
Why this is correct
Spot instances offer large discounts but can be interrupted; with checkpointing, training can resume, saving costs.
- ✗
Reserved instances
Why it's wrong here
Reserved instances require a 1- or 3-year commitment and are not ideal for intermittent training jobs.
- ✗
Dedicated hosts
Why it's wrong here
Dedicated hosts are physical servers for compliance; they are expensive and not cost-saving.
- ✗
On-demand instances
Why it's wrong here
