Troubleshooting CloudFront Static Website: Enable S3 Static Website Hosting

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.

A
The S3 bucket is not configured for static website hosting; CloudFront should use the bucket's website endpoint as the origin.
Why wrong: For static website hosting, the origin must be the S3 website endpoint, not the bucket's REST endpoint.
B
The S3 bucket policy does not grant CloudFront access.
Why wrong: The bucket policy allows public read, so CloudFront can access it.
C
The CloudFront distribution is not configured to use HTTPS.
Why wrong: CloudFront supports HTTPS by default for its domain.
D
The CloudFront distribution is not associated with an origin access identity (OAI).
OAI is not required for public buckets.

Correct answer & explanation

✓

The CloudFront distribution is not associated with an origin access identity (OAI).

The most likely reason is that the S3 bucket is not configured for static website hosting. CloudFront can use either the S3 REST endpoint or the static website hosting endpoint as the origin. If the bucket is not enabled for static website hosting, the website endpoint is not available. Without the website endpoint, CloudFront cannot serve the index document or handle error pages, which are essential for a static website. Even though the distribution is deployed and the bucket policy allows public read access, using the REST endpoint will not serve the website correctly. To resolve this, the company should enable static website hosting on the S3 bucket and configure the CloudFront origin to use the bucket's website endpoint. Option B is incorrect because the bucket policy already allows public read, so CloudFront does not need additional access unless an Origin Access Identity is used. Option C is incorrect because CloudFront supports HTTPS by default for its default domain. Option D is incorrect because an OAI is not required when the bucket allows public access.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
