Quick Answer
The correct combination includes implementing Amazon CloudFront as a CDN, enabling Regional Edge Caches, and using Origin Shield. This trio works together to minimize latency for video content delivery with CloudFront and S3 by caching content at edge locations closest to users, then at regional caches for less popular assets, and finally consolidating requests through Origin Shield to reduce the load on the S3 origin. On the SAA-C03 exam, this scenario tests your understanding of layered caching strategies—a common trap is choosing only CloudFront and S3, forgetting that Regional Edge Caches and Origin Shield are separate, optional features that drastically improve cache hit ratios and origin offload. Remember the memory tip: "Edge, Region, Shield—three layers to yield."
SAA-C03 Design High-Performing Architectures Practice Question
This SAA-C03 practice question tests your understanding of design high-performing 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.
A media company is designing a high-performance architecture to serve video content to users worldwide. The solution must minimize latency for end users and reduce the load on the origin servers. The video files are stored in an Amazon S3 bucket. Which three options should be combined to meet these requirements? (Choose three.)

Correct answer & explanation
✓
Use Amazon CloudFront as a content delivery network (CDN) with the S3 bucket as the origin.
Amazon CloudFront as a CDN with the S3 bucket as the origin minimizes latency by caching video content at edge locations worldwide, serving users from the nearest edge. This reduces load on the origin S3 bucket by handling requests at the edge. Regional Edge Caches further improve cache hit ratios for less popular content by caching it at regional locations, reducing the need to fetch from the origin. Origin shield in CloudFront consolidates requests from multiple edge locations into a single request to the S3 origin, significantly reducing the number of direct requests and lowering origin load.
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 may confuse S3 Transfer Acceleration (which optimizes uploads) with CloudFront (which optimizes downloads), or think that ElastiCache can be used as a CDN for video content, when it is actually an in-memory cache for application data, not for serving static files at the edge.
Detailed technical explanation
How to think about this question
CloudFront origin shield works by creating an additional caching layer between edge locations and the origin, reducing the number of requests that reach the S3 bucket. Regional Edge Caches have larger caches than edge locations, allowing them to store less popular content for longer, which improves cache hit ratios. Under the hood, CloudFront uses HTTP/2 and TCP optimizations to accelerate content delivery, and it supports custom SSL/TLS termination at the edge for secure streaming.
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 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.
