- A
Deploy multiple Application Load Balancers in different regions.
Allows serving content from regional origins, reducing cross-region data transfer.
- B
Use Amazon CloudFront to cache content at edge locations.
Reduces data transfer from origin.
- C
Use AWS Direct Connect for all traffic.
Why wrong: Direct Connect reduces data transfer costs for dedicated connections but not for global content delivery.
- D
Use a single S3 bucket in one region with cross-region replication.
Why wrong: Replication incurs costs; does not reduce data transfer for users.
- E
Enable S3 Transfer Acceleration.
Why wrong: Reduces latency for uploads, not data transfer costs.

SOA-C02 Networking and Content Delivery Practice Question
This SOA-C02 practice question tests your understanding of networking and content delivery. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which TWO actions can reduce data transfer costs for content delivered to users globally? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deploy multiple Application Load Balancers in different regions.
Option A is correct because deploying multiple Application Load Balancers (ALBs) in different regions allows traffic to be routed to the nearest regional endpoint, reducing the distance data must travel over the public internet and lowering egress costs. Option B is correct because Amazon CloudFront caches content at edge locations closer to users, minimizing the amount of data transferred from the origin and reducing overall data transfer costs, especially for frequently accessed static content.
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
The trap here is that candidates often confuse S3 Transfer Acceleration or cross-region replication as cost-saving measures for content delivery, when in fact they add costs and do not reduce egress charges for global users.
Detailed technical explanation
How to think about this question
Under the hood, CloudFront uses a global network of edge locations to serve cached content via HTTP/HTTPS, reducing origin load and egress costs by up to 70% for static assets. Multiple ALBs in different regions, combined with Route 53 latency-based routing or geolocation routing, ensure that user traffic terminates at the nearest regional endpoint, minimizing cross-region data transfer and associated AWS egress fees. This approach is particularly effective for dynamic content that cannot be cached but still benefits from regional proximity.
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.
TExam Day Tips
- 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.
