MLA-C01 Practice Question: Secure a SageMaker notebook instance that…
A company needs to secure a SageMaker notebook instance that contains sensitive data. Which THREE of the following are effective security measures? (Select THREE.)
⚠ Common exam trap
A common trap is to consider AWS CloudTrail as an effective security measure for protecting the notebook instance itself. While CloudTrail provides an audit trail, it does not prevent unauthorized access or data leakage. Direct security controls like IAM, VPC configuration, and encryption are more effective.
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
✓
Use IAM policies to restrict who can access the notebook instance.
Option A is correct because IAM policies are the primary mechanism for controlling authentication and authorization to SageMaker notebook instances, allowing you to restrict which principals can create, access, or manage the instance via fine-grained permissions. Option B is correct because disabling direct internet access forces all outbound traffic through your VPC, and a NAT gateway provides controlled, monitored egress while preventing the notebook from being directly reachable from the internet. Option E is correct because encrypting the notebook instance's EBS volume with AWS KMS protects data at rest, ensuring that sensitive data stored on the volume is unreadable if the underlying storage is compromised. Option C is not a security measure because downloading data from a public S3 bucket introduces unnecessary exposure and does not secure the notebook. Option D, while useful for auditing, is a detective control rather than a preventive security measure and does not by itself secure the sensitive data on the instance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use IAM policies to restrict who can access the notebook instance.
Why this is correct
IAM policies define which principals may invoke SageMaker notebook instance actions such as CreatePresignedNotebookInstanceUrl, directly restricting access to the sensitive data. This enforces least privilege at the identity layer, satisfying the requirement to secure the notebook.
- ✓
Disable direct internet access and use a VPC with a NAT gateway for outbound.
Why this is correct
Disabling direct internet access forces notebook traffic through the VPC, and a NAT gateway permits only outbound access, blocking inbound exposure from the internet. This satisfies the requirement to secure a notebook holding sensitive data by removing its public network path.
- ✗
Attach a lifecycle configuration that runs a script to download data from a public S3 bucket.
Why it's wrong here
Downloading data from a public S3 bucket introduces untrusted external content and broadens exposure, directly undermining the notebook's security posture. It is tempting because lifecycle configurations legitimately automate notebook setup tasks, but they are the right choice for installing approved packages or configuring settings from controlled, private sources.
- ✗
Enable AWS CloudTrail to log all notebook API calls.
Why it's wrong here
CloudTrail records API activity for auditing and detection; it does not restrict access to the notebook, encrypt its data, or isolate its network, so it cannot by itself secure sensitive content. It is tempting because logging is a genuine security control, and it would be correct when the requirement is audit visibility or compliance evidence.
- ✓
Encrypt the notebook instance's EBS volume using AWS KMS.
Why this is correct
AWS KMS encryption on the notebook instance's EBS volume protects data at rest, so sensitive contents remain unreadable if the underlying storage is compromised. This satisfies the requirement to secure a notebook containing sensitive data, complementing network controls that address data in transit.

| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| 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 |
