- A
Configure the endpoint's security group to allow outbound traffic to the S3 bucket's IP range.
Why wrong: Security groups do not control access to S3; they control network traffic to the endpoint.
- B
Attach the endpoint to a VPC that has a VPC endpoint for S3.
VPC endpoints allow private connectivity to S3 without internet.
- C
Ensure the SageMaker execution role has an IAM policy that grants s3:GetObject access to the bucket.
The execution role needs permissions to access the S3 bucket.
- D
Attach the endpoint to a VPC with an internet gateway and route the S3 traffic through the internet gateway.
Why wrong: This uses the public internet, violating the requirement.
- E
Attach the endpoint to a VPC with a NAT gateway to route traffic to S3.
Why wrong: NAT gateway is for outbound internet, not private S3 access.
MLA-C01 Deployment and Orchestration of ML Workflows Practice Question
This MLA-C01 practice question tests your understanding of deployment and orchestration of ml workflows. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 is using Amazon SageMaker to deploy a model for real-time inference. The model requires access to a private S3 bucket that contains reference data. The company wants to ensure that the endpoint can access the S3 bucket without using a public internet connection. Which TWO actions should they take? (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
Attach the endpoint to a VPC that has a VPC endpoint for S3.
Option B is correct because attaching the SageMaker endpoint to a VPC with a VPC endpoint for S3 (Gateway type) allows the endpoint to access the S3 bucket using AWS's private network, bypassing the public internet. This ensures traffic stays within the AWS backbone, meeting the requirement for no public internet connection. Option C is also correct because the SageMaker execution role must have an IAM policy with s3:GetObject permissions to authorize the read access to the private S3 bucket, which is a prerequisite for any S3 operation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse VPC endpoints (which keep traffic private) with NAT gateways or internet gateways (which route traffic over the public internet), and they may overlook the mandatory IAM permissions required for S3 access even when using a VPC endpoint.
Detailed technical explanation
How to think about this question
A VPC endpoint for S3 (Gateway type) uses prefix lists and route table entries to direct S3 traffic through the AWS network, not the internet. SageMaker endpoints are deployed in a VPC using the 'VpcConfig' parameter, which requires subnets and security groups; the execution role's IAM policy must include 's3:GetObject' and optionally 's3:ListBucket' for the specific bucket ARN. In real-world scenarios, this setup is critical for compliance with data sovereignty or security policies that mandate private network traffic.
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.
