The correct answer is to store content in an S3 bucket and use Amazon CloudFront with S3 as the origin. This combination delivers static content globally with low latency because CloudFront caches files at edge locations close to users, while S3 provides durable, highly available storage for the originals. For infrequent updates that must be reflected immediately, CloudFront supports cache invalidations to purge stale content on demand. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of optimizing for global performance without over-engineering—a common trap is adding an Application Load Balancer or ElastiCache, which introduces unnecessary cost and complexity for static assets. Remember the memory tip: “Static + Global + Low Latency = S3 Origin with CloudFront and invalidations.”
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. 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 is designing a new web application that will serve static content (HTML, CSS, JS, images) to users globally. The application must have low latency and high availability. Content changes infrequently, but when updated, the changes must be reflected immediately. Which solution should the architect recommend?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Store content in an S3 bucket and use Amazon CloudFront with S3 as origin
Option B is correct because CloudFront can serve static content from an S3 bucket with low latency, and invalidations can be used to immediately update content. Option A is wrong because S3 alone does not provide global low latency. Option C is wrong because CloudFront with an ALB adds unnecessary complexity and cost for static content. Option D is wrong because ElastiCache is not designed for serving static files.
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.
✓
Store content in an S3 bucket and use Amazon CloudFront with S3 as origin
Why this is correct
CloudFront provides global edge caching for low latency, and invalidations allow immediate content updates.
Clue confirmation
The clue word "immediately / without restart" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Store content on an EC2 instance behind an Application Load Balancer and use CloudFront
Why it's wrong here
This adds unnecessary complexity and cost; S3 is sufficient for static content.
✗
Store content in Amazon ElastiCache for Redis and use CloudFront
Why it's wrong here
ElastiCache is a caching layer, not designed for storing and serving static files.
✗
Store content in an S3 bucket and use S3 Transfer Acceleration
Why it's wrong here
S3 alone does not provide global low latency; Transfer Acceleration speeds up uploads, not downloads.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
