MLA-C01 SageMaker Endpoint VPC Configuration Practice Question
This MLA-C01 practice question tests your understanding of sagemaker endpoint vpc configuration. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. A key principle to apply: sageMaker Endpoint VPC Configuration. 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.
Refer to the exhibit. A SageMaker endpoint is logging this error when processing inference requests that require database access. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The endpoint lacks a VPC configuration with proper security groups
The question references an exhibit that is not provided, making the answer unverifiable. Without the specific error details from the exhibit, it is impossible to confirm the cause. However, in typical scenarios, database connectivity issues for SageMaker endpoints are often due to missing or misconfigured VPC settings. But due to missing context, no option can be definitively selected.
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Data capture is not enabled
Why it's wrong here
Data capture not being enabled would not cause a database connectivity error.
✗
The endpoint instance type is too small
Why it's wrong here
Instance size might affect performance but not network connectivity to a database.
✗
The model is not compatible with the instance
Why it's wrong here
Model compatibility issues typically cause inference errors, not database connection failures.
✓
The endpoint lacks a VPC configuration with proper security groups
Why this is correct
Lack of VPC configuration is a common cause, but without the exhibit, this cannot be confirmed.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
This question is incomplete because the exhibit is missing, so the answer cannot be verified. In a real exam, always ensure you have all referenced exhibits.
Detailed technical explanation
How to think about this question
SageMaker endpoints by default run in a managed AWS network without VPC attachment. To access resources in a VPC (e.g., an RDS database), the endpoint must be configured with a VPC subnet and security group that allows outbound traffic (e.g., port 3306 for MySQL or 5432 for PostgreSQL). Additionally, the database's security group must allow inbound traffic from the endpoint's security group. This is a common misconfiguration when deploying models that rely on external data stores.

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.
