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.
A company has deployed a static website on Amazon S3 with public read access. They want to use Amazon CloudFront to serve the content with HTTPS. They create a CloudFront distribution with the S3 bucket as an origin. After configuring the distribution, users report that they are unable to access the website via the CloudFront URL. The CloudFront distribution status is 'Deployed'. The S3 bucket policy allows GetObject for any principal. What is the most likely reason for the issue?
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 S3 bucket is not configured for static website hosting; CloudFront should use the bucket's website endpoint as the origin.
Option A is correct. By default, CloudFront does not cache HTTPS traffic from S3 if the origin protocol policy is set to 'Match Viewer'. If the viewer uses HTTP, CloudFront will use HTTP to fetch from S3, but S3 does not support HTTPS for static website hosting unless configured. However, the most common issue is that the CloudFront distribution does not have an SSL certificate for the custom domain. But the question says 'CloudFront URL', so likely the default CloudFront domain (xxxx.cloudfront.net) is used. That domain supports HTTPS by default. The actual issue is that the S3 bucket is configured for static website hosting, and the CloudFront origin domain name should be the S3 website endpoint, not the bucket's REST endpoint. If they used the bucket endpoint, CloudFront might not be able to access it properly. Option B is wrong because the bucket policy allows public read. Option C is wrong because CloudFront automatically encrypts to S3 if using HTTPS. Option D is wrong because CloudFront can serve content from S3 without OAI.
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 S3 bucket is not configured for static website hosting; CloudFront should use the bucket's website endpoint as the origin.
Why this is correct
For static website hosting, the origin must be the S3 website endpoint, not the bucket's REST endpoint.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The S3 bucket policy does not grant CloudFront access.
Why it's wrong here
The bucket policy allows public read, so CloudFront can access it.
✗
The CloudFront distribution is not configured to use HTTPS.
Why it's wrong here
CloudFront supports HTTPS by default for its domain.
✗
The CloudFront distribution is not associated with an origin access identity (OAI).
Why it's wrong here
OAI is not required for public buckets.
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.

If the viewer uses HTTP, CloudFront will use HTTP to fetch from S3, but S3 does not support HTTPS for static website hosting unless configured. However, the most common issue is that the CloudFront distribution does not have an SSL certificate for the custom domain. But the question says 'CloudFront URL', so likely the default CloudFront domain (xxxx.cloudfront.net) is used. That domain supports HTTPS by default. The actual issue is that the S3 bucket is configured for static website hosting, and the CloudFront origin domain name should be the S3 website endpoint, not the bucket's REST endpoint. If they used the bucket endpoint, CloudFront might not be able to access it properly. Option B is wrong because the bucket policy allows public read.
