- A
CloudFront: Content delivery with low latency to global users
CloudFront is a CDN that reduces latency by caching content at edge locations, directly addressing the need for low-latency content delivery.
- B
VPC Peering: Private connectivity between VPCs in same region
VPC peering provides direct, private connectivity between two VPCs in the same region without additional transit costs, reducing cost for intra-region connectivity.
- C
Direct Connect: Dedicated network connection from on-premises to AWS
Direct Connect provides a dedicated, private link from on-premises to AWS, reducing data transfer costs compared to internet-based VPNs for hybrid connectivity.
- D
Transit Gateway: Point-to-point connectivity between two VPCs
Why wrong: Incorrect — Transit Gateway is a hub-and-spoke model for connecting multiple VPCs, not optimized for simple point-to-point connectivity; VPC peering is more cost-effective for two VPCs.
- E
Global Accelerator: Low-latency content delivery to edge locations
Why wrong: Incorrect — Global Accelerator improves performance for TCP/UDP applications by routing traffic to optimal endpoints, but it is not a content delivery service; CloudFront is designed for content delivery.
SAA-C03 Design Cost-Optimized Architectures Practice Question
This SAA-C03 practice question tests your understanding of design cost-optimized architectures. 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.
Match each private-networking or content-delivery scenario to the AWS feature that most directly reduces cost while meeting the connectivity requirement.
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
CloudFront: Content delivery with low latency to global users
Each AWS feature directly reduces cost for the given scenario: CloudFront for latency, VPC Peering for intra-region, Direct Connect for hybrid, Transit Gateway for inter-region, Shield+CloudFront for security, and Global Accelerator for inter-region data transfer costs.
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 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.
