MLA-C01 SageMaker Endpoint VPC Configuration Practice Question
Exhibit
[ERROR] 2024-03-15 10:23:45,234 - botocore.exception.ConnectTimeoutError: Connect timeout on endpoint URL: "https://database.example.com:5432"
A SageMaker endpoint is logging an error when processing inference requests that require database access. What is the most likely cause?
⚠ Common exam trap
Some candidates might think that database connectivity issues are due to endpoint instance size or missing data capture configuration. However, the key for accessing external resources from SageMaker is VPC configuration.
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
✓
The endpoint lacks a VPC configuration with proper security groups
When a SageMaker endpoint needs to access an external database (e.g., Amazon RDS) during inference, it must be launched within a VPC that has proper security group and subnet configurations. If the endpoint is not in a VPC or the security groups do not allow outbound traffic to the database, the endpoint will be unable to connect, resulting in errors. The other options are less likely: data capture is for logging requests (A), instance size affects performance not connectivity (B), model compatibility affects deployment but not specifically database access (C).
Answer analysis
Option-by-option breakdown
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 is for storing inference requests and responses, not for enabling database access.
- ✗
The endpoint instance type is too small
Why it's wrong here
Instance size may affect performance but not network connectivity to a database.
- ✗
The model is not compatible with the instance
Why it's wrong here
Compatibility issues would prevent deployment, not cause database-specific errors.
- ✓
The endpoint lacks a VPC configuration with proper security groups
Why this is correct
Correct. Without VPC and security groups, the endpoint cannot reach the database.
