The correct answer is to enable SageMaker Studio’s data encryption using a customer managed key (CMK) and configure the notebook to use HTTPS for all traffic. This configuration satisfies both encryption requirements because the CMK encrypts data at rest on the underlying Amazon EFS persistent storage, while HTTPS ensures all data in transit between the notebook and other services is encrypted. On the AWS Certified AI Practitioner AIF-C01 exam, this question tests your understanding of SageMaker Studio’s dual-layer security model: you must remember that encryption at rest requires a CMK (not the default AWS managed key) and that encryption in transit specifically needs HTTPS enabled on the notebook. A common trap is choosing only one encryption method, such as just enabling a CMK, which fails the policy’s “both at rest and in transit” requirement. Memory tip: think “CMK for the disk, HTTPS for the trip.”
AIF-C01 Practice Question: Security, Compliance and Governance for AI Solutions
This AIF-C01 practice question tests your understanding of security, compliance and governance for ai solutions. 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. 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 data scientist is using Amazon SageMaker Studio. The company policy requires that all data used in SageMaker Studio notebooks be encrypted at rest and in transit. Which configuration should be enabled to meet this requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable SageMaker Studio's data encryption using a customer managed key (CMK) and configure the notebook to use HTTPS for all traffic.
Option D is correct because it addresses both encryption at rest and in transit. SageMaker Studio uses Amazon EFS for persistent storage, and enabling encryption at rest with a customer managed key (CMK) ensures data on the EFS file system is encrypted. Additionally, configuring the notebook to use HTTPS ensures all traffic between the notebook and other services is encrypted in transit, meeting the company policy.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Store all data in encrypted DynamoDB tables and query from notebooks.
Why it's wrong here
Not relevant; data must still be protected within Studio.
✗
Use a VPC with no internet access and enable S3 encryption for all data.
Why it's wrong here
Does not encrypt data in the Studio notebook environment itself.
✗
Enable SageMaker Studio's default encryption using the AWS managed key for EFS.
Why it's wrong here
Uses default key, not a customer managed key, which may not satisfy compliance.
✓
Enable SageMaker Studio's data encryption using a customer managed key (CMK) and configure the notebook to use HTTPS for all traffic.
Why this is correct
Ensures encryption at rest (CMK) and in transit (HTTPS).

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume default encryption (Option C) is sufficient, but it only covers data at rest on EFS and ignores the encryption in transit requirement, which is explicitly tested in this scenario.
Detailed technical explanation
How to think about this question
SageMaker Studio provisions an Amazon EFS file system per user for persistent storage, and encryption at rest can be enabled using either an AWS managed key or a customer managed key (CMK). For encryption in transit, HTTPS (TLS) must be enforced for all notebook traffic, which can be configured via the SageMaker Studio settings or by using a VPC with appropriate security groups. Under the hood, SageMaker Studio uses JupyterLab, and HTTPS ensures that all kernel-to-client and client-to-service communications are encrypted, preventing data exposure during active sessions.

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.
