- A
Use AWS Lake Formation to grant cross-account access to the bucket
Why wrong: Lake Formation governs data lakes in the same account or via Resource Access Manager, but direct S3 bucket access for Bedrock is not managed by Lake Formation.
- B
Copy the S3 bucket to the same account as Bedrock
Why wrong: Copying data is inefficient and may violate data residency requirements; cross-account access can be secured with policies.
- C
Configure the S3 bucket policy to allow access from the Bedrock service role and add a Bedrock resource policy allowing the bucket
This two-way policy approach ensures only the specified Bedrock role can access the bucket, following cross-account security best practices.
- D
Make the S3 bucket public and use a pre-signed URL
Why wrong: Making the bucket public violates security best practices; pre-signed URLs are for temporary access, not for ongoing model access.
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. 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 data scientist needs to allow a foundation model in Amazon Bedrock to access a specific S3 bucket containing reference documents. The bucket is in a different AWS account. What is the MOST secure way to grant access?
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
Configure the S3 bucket policy to allow access from the Bedrock service role and add a Bedrock resource policy allowing the bucket
Cross-account access requires both the S3 bucket policy to grant the Bedrock service role and the Bedrock resource policy to allow the bucket, ensuring least privilege.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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 AWS Lake Formation to grant cross-account access to the bucket
Why it's wrong here
Lake Formation governs data lakes in the same account or via Resource Access Manager, but direct S3 bucket access for Bedrock is not managed by Lake Formation.
- ✗
Copy the S3 bucket to the same account as Bedrock
Why it's wrong here
Copying data is inefficient and may violate data residency requirements; cross-account access can be secured with policies.
- ✓
Configure the S3 bucket policy to allow access from the Bedrock service role and add a Bedrock resource policy allowing the bucket
Why this is correct
This two-way policy approach ensures only the specified Bedrock role can access the bucket, following cross-account security best practices.
Related concept
Authentication checks who the user is.
- ✗
Make the S3 bucket public and use a pre-signed URL
Why it's wrong here
Making the bucket public violates security best practices; pre-signed URLs are for temporary access, not for ongoing model access.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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.
Quick reference
AWS S3 Storage Class Comparison
| 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 |
