SOA-C02 Networking and Content Delivery Practice Question
This SOA-C02 practice question tests your understanding of networking and content delivery. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 is using Amazon CloudFront to serve static content from an S3 bucket. They want to restrict access so that only CloudFront can access the S3 bucket. How should this be configured?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure Origin Access Control (OAC) with the S3 bucket policy.
Option D is correct because Origin Access Control (OAC) ensures only CloudFront can access the bucket. Option A is wrong because bucket policies can be used but OAC is the modern recommended approach. Option B is wrong because CloudFront key pairs are for signed URLs/cookies, not origin access. Option C is wrong because IAM roles are used for EC2, not for CloudFront access to S3.
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.
✓
Configure Origin Access Control (OAC) with the S3 bucket policy.
Why this is correct
OAC is the recommended way to restrict S3 access to CloudFront.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use CloudFront signed URLs or cookies.
Why it's wrong here
Signed URLs/cookies control viewer access, not origin access.
✗
Attach an IAM role to CloudFront that grants S3 read access.
Why it's wrong here
CloudFront cannot assume IAM roles; it uses OAC.
✗
Create a bucket policy that allows access only from the CloudFront distribution's IP addresses.
Why it's wrong here
CloudFront IP addresses change, so this is not reliable.
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.
