MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
A team trains a model using SageMaker and wants to ensure that the training job cannot access the internet, but needs to access a private S3 bucket in the same VPC. Which configuration should they use?
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
✓
Enable network isolation and provide VPC subnet and security group
SageMaker training jobs can be configured with VPC settings. Enabling network isolation prevents internet access, but the job still needs VPC connectivity to reach S3 via VPC endpoints. Setting the VPC config allows access to private resources.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable network isolation and provide VPC subnet and security group
Why this is correct
Network isolation blocks internet; VPC config allows access to private resources via VPC endpoints.
- ✗
Enable network isolation only, without VPC configuration
Why it's wrong here
Without VPC config, the job cannot reach any VPC resources, including private S3.
- ✗
Disable network isolation but restrict security group rules
Why it's wrong here
Disabling network isolation allows internet access; security group rules may still allow outbound traffic.
- ✗
Use a public S3 bucket with bucket policies
Why it's wrong here
Using a public bucket would expose data and does not meet the private requirement.

| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
