SOA-C02 Networking and Content Delivery Practice Question
This SOA-C02 practice question tests your understanding of networking and content delivery. 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 company hosts a static website on Amazon S3 with public read access enabled. The website is accessed via a custom domain name that uses Amazon Route 53. The domain name points to the S3 bucket's website endpoint. Users report that they can access the website using the S3 bucket URL but not the custom domain name. 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.
The S3 bucket policy does not allow public access.
Why wrong: The question states public read access is enabled.
B
The website does not support HTTPS and the browser blocks it.
Why wrong: S3 website endpoints support HTTP only, but browsers do not block HTTP unless forced.
C
The Route 53 alias record points to the S3 bucket's regional endpoint instead of the website endpoint.
For static website hosting, the alias target must be the S3 website endpoint (e.g., bucket-name.s3-website-region.amazonaws.com), not the bucket's regional endpoint (s3.amazonaws.com).
D
The DNS TTL is too long and the changes have not propagated.
Why wrong: If the alias record is correct, propagation would eventually work. The issue is likely the target.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Route 53 alias record points to the S3 bucket's regional endpoint instead of the website endpoint.
The Route 53 alias record must point to the S3 website endpoint, not the bucket's regional endpoint. Option A is incorrect because DNS resolution might be working but the record points to the wrong target. Option C is incorrect because the bucket policy allows public reads. Option D is incorrect because S3 website hosting does not require HTTPS by default.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
The S3 bucket policy does not allow public access.
Why it's wrong here
The question states public read access is enabled.

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.
