- A
Grant Lake Formation permissions on the tables and attach an S3 bucket policy with aws:SourceIp condition
Why wrong: S3 bucket policy does not control Athena queries via Lake Formation.
- B
Grant Lake Formation permissions on the tables and attach an IAM policy to the user with aws:SourceIp condition
Correct combination.
- C
Use an S3 VPC endpoint and grant Lake Formation permissions on the tables
Why wrong: VPC endpoint does not restrict IP; it restricts network path.
- D
Grant Lake Formation permissions on the tables and configure a network ACL in the VPC
Why wrong: NACL does not restrict user-specific access.

DEA-C01 Data Security and Governance Practice Question
This DEA-C01 practice question tests your understanding of data security and governance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 company uses AWS Lake Formation to manage access to data in a data lake. The data engineer needs to grant a user the ability to query tables in the 'sales' database using Amazon Athena, but only when the user's IP address is within the corporate network (10.0.0.0/8). Which combination of actions should the data engineer take?
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
✓
Grant Lake Formation permissions on the tables and attach an IAM policy to the user with aws:SourceIp condition
Option B is correct because Lake Formation permissions are needed to grant query access to the tables in the 'sales' database, and an IAM policy attached to the user with a condition key `aws:SourceIp` restricts Athena access to the corporate IP range (10.0.0.0/8). Option A is incorrect because S3 bucket policies with `aws:SourceIp` cannot be used to restrict Athena queries through Lake Formation; Lake Formation manages access at a higher level. Option C is incorrect because using an S3 VPC endpoint alone does not enforce IP-based restrictions; it only restricts network traffic to the VPC. Option D is incorrect because network ACLs operate at the subnet level and do not control access to specific Lake Formation resources or Athena queries.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Grant Lake Formation permissions on the tables and attach an S3 bucket policy with aws:SourceIp condition
Why it's wrong here
S3 bucket policy does not control Athena queries via Lake Formation.
- ✓
Grant Lake Formation permissions on the tables and attach an IAM policy to the user with aws:SourceIp condition
Why this is correct
Correct combination.
Related concept
CIDR notation defines the prefix length.
- ✗
Use an S3 VPC endpoint and grant Lake Formation permissions on the tables
Why it's wrong here
VPC endpoint does not restrict IP; it restricts network path.
- ✗
Grant Lake Formation permissions on the tables and configure a network ACL in the VPC
Why it's wrong here
NACL does not restrict user-specific access.
Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
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 |
