The answer is that the policy enforces access restricted to a specific IP range. This is correct because the S3 bucket policy uses the `aws:SourceIp` condition key with a CIDR block, which tells the AWS service to allow or deny requests based on the requester’s IP address. By pairing this condition with allowed actions like GET requests, the policy creates a network-level firewall, ensuring only clients within that defined IP range can acquire data from the bucket. On the CompTIA Data+ DA0-001 exam, this scenario tests your understanding of data acquisition controls and how S3 bucket policies implement network security—a common trap is confusing IP-based restrictions with user-based IAM policies or encryption requirements. Remember, `SourceIp` equals source IP, so think of it as a digital bouncer checking IDs at the network door.
DA0-001 Mining and Acquiring Data Practice Question
This DA0-001 practice question tests your understanding of mining and acquiring data. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Access is restricted to a specific IP range
The S3 bucket policy includes a condition using `aws:SourceIp` with a CIDR block, which restricts access to requests originating from the specified IP range. This enforces network-level access control, allowing only clients within that IP range to perform the allowed actions (like GET requests) on the bucket. Option D correctly identifies this IP-based restriction.
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.
✗
Only objects with key 'data-bucket' can be accessed
Why it's wrong here
'data-bucket' is the bucket name, not an object key.
✗
Only GET requests are allowed
Why it's wrong here
While true, this is not the only enforcement; the IP restriction is key.
✗
The bucket is publicly accessible
Why it's wrong here
The policy restricts access to a specific IP range, so it is not public.
✓
Access is restricted to a specific IP range
Why this is correct
The condition limits access to IPs in the 10.0.0.0/8 range.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the misconception that a Deny statement with a condition on IP addresses makes the bucket publicly accessible, when in fact it restricts access to only the specified IP range.
Detailed technical explanation
How to think about this question
The `aws:SourceIp` condition key evaluates the source IP address of the request, which is derived from the TCP connection's source address. This is commonly used with VPC endpoints or corporate VPNs to restrict S3 access to trusted networks. Under the hood, AWS IAM evaluates the policy's `Effect: Deny` with the `NotIpAddress` condition first, which overrides any `Allow` statements for requests from IPs outside the range, ensuring strict enforcement.

Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
