- A
Attach a resource policy to the endpoint that restricts access to the VPC endpoint
The resource policy ensures only traffic from the VPC endpoint is allowed.
- B
Enable network isolation mode on the endpoint
Why wrong: Network isolation removes internet access but does not restrict invocation to a VPC.
- C
Create a VPC endpoint for SageMaker (com.amazonaws.region.sagemaker.api)
A VPC endpoint allows private connectivity without internet.
- D
Use a VPC with a NAT gateway and configure the endpoint to use the VPC
Why wrong: A NAT gateway allows outbound internet, not inbound restriction.
- E
Enable inter-container traffic encryption on the endpoint
Why wrong: This encrypts traffic between containers within the endpoint, not the invocation path.

MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
This MLA-C01 practice question tests your understanding of ml solution monitoring, maintenance, and security. 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 wants to ensure that a SageMaker endpoint can only be invoked from within a specific VPC and that the data in transit is encrypted. Which THREE steps should they take? (Select THREE.)
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 a resource policy to the endpoint that restricts access to the VPC endpoint
To restrict access to a VPC, use a VPC endpoint for SageMaker. To enforce that only requests from that VPC are accepted, use a resource policy that denies requests unless they come via the VPC endpoint. Inter-container traffic encryption secures data between containers, but for endpoint invocation, using a VPC endpoint with encryption ensures data in transit is encrypted.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Attach a resource policy to the endpoint that restricts access to the VPC endpoint
Why this is correct
The resource policy ensures only traffic from the VPC endpoint is allowed.
Related concept
Static NAT maps one inside address to one outside address.
- ✗
Enable network isolation mode on the endpoint
Why it's wrong here
Network isolation removes internet access but does not restrict invocation to a VPC.
- ✓
Create a VPC endpoint for SageMaker (com.amazonaws.region.sagemaker.api)
Why this is correct
A VPC endpoint allows private connectivity without internet.
Related concept
Static NAT maps one inside address to one outside address.
- ✗
Use a VPC with a NAT gateway and configure the endpoint to use the VPC
- ✗
Enable inter-container traffic encryption on the endpoint
Why it's wrong here
This encrypts traffic between containers within the endpoint, not the invocation path.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related MLA-C01 NAT questions on configuration and troubleshooting.
