SOA-C02 Networking and Content Delivery Practice Question
This SOA-C02 practice question tests your understanding of networking and content delivery. 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.
Refer to the exhibit. This bucket policy is attached to an S3 bucket that is used as an origin for a CloudFront distribution. Users are reporting Access Denied errors when accessing objects via the CloudFront URL. What is the MOST likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The condition restricts access to a specific IP range, but CloudFront requests come from its own IP addresses.
Option D is the most likely cause. The bucket policy includes a condition that restricts access to a specific IP range (192.0.2.0/24). However, when CloudFront serves content from an S3 origin, the requests to S3 originate from CloudFront's own IP addresses, not the end user's IP. Therefore, the condition fails and blocks CloudFront, resulting in Access Denied errors. Option A is incorrect because the aws:SourceVpce condition is used for VPC endpoints, not CloudFront. Option B is incorrect because the bucket policy can use an Origin Access Identity (OAI) instead of granting access to the CloudFront service principal, but the issue here is the IP restriction. Option C is incorrect because the resource ARN includes /*, which is typically correct for bucket policies allowing access to all objects.
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.
✗
The condition is missing the aws:SourceVpce condition for VPC endpoints.
Why it's wrong here
This condition is irrelevant for CloudFront access.
✗
The bucket policy does not grant access to the CloudFront service principal.
Why it's wrong here
CloudFront can access S3 via OAI without needing a service principal in the bucket policy.
✗
The resource ARN is missing the bucket ARN for the bucket itself.
Why it's wrong here
The resource ARN includes all objects; it is correct.
✓
The condition restricts access to a specific IP range, but CloudFront requests come from its own IP addresses.
Why this is correct
CloudFront uses its own IP addresses to fetch objects from the origin; the user's IP is not forwarded by default.
Clue confirmation

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.

However, when CloudFront serves content from an S3 origin, the requests to S3 originate from CloudFront's own IP addresses, not the end user's IP. Therefore, the condition fails and blocks CloudFront, resulting in Access Denied errors. Option A is incorrect because the aws:SourceVpce condition is used for VPC endpoints, not CloudFront. Option B is incorrect because the bucket policy can use an Origin Access Identity (OAI) instead of granting access to the CloudFront service principal, but the issue here is the IP restriction.
