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. A key principle to apply: aWS Global Accelerator uses static Anycast IP addresses.. 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 analytics dashboard uses an Application Load Balancer in one Region. Global users need lower network latency to the application without caching dynamic responses. What should be considered?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Global Accelerator
AWS Global Accelerator uses the AWS global network and Anycast IPs to route traffic to the optimal Regional endpoint, reducing latency for global users without caching dynamic responses. It does not cache content, so dynamic data is always fetched from the origin, meeting the requirement of no caching while improving network performance via the AWS backbone.
Key principle: AWS Global Accelerator uses static Anycast IP addresses.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
AWS Global Accelerator
Why this is correct
Global Accelerator routes traffic over the AWS global network to improve performance for TCP/UDP applications without relying on caching.
Related concept
AWS Global Accelerator uses static Anycast IP addresses.
✗
S3 Cross-Region Replication
Why it's wrong here
CRR replicates objects and does not optimize dynamic application routing.
✗
AWS Backup cross-Region copy
Why it's wrong here
Backup copies do not reduce live user latency.
✗
CloudFront only with long TTLs
Why it's wrong here
CloudFront is strongest for cacheable HTTP content; long TTLs can be wrong for dynamic responses.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose CloudFront for any global latency improvement, but the requirement of 'no caching dynamic responses' disqualifies CloudFront unless TTL=0 is used, which still incurs edge request overhead, whereas Global Accelerator is purpose-built for non-cached dynamic traffic.
Detailed technical explanation
How to think about this question
AWS Global Accelerator leverages Anycast IP addresses so that user traffic enters the AWS global network at the closest edge location, then travels over the private AWS backbone to the ALB, bypassing public internet congestion. It supports TCP and UDP traffic and provides two static IPs that act as fixed entry points, which is ideal for clients that require IP whitelisting or cannot use DNS-based routing. Under the hood, it uses the same infrastructure as CloudFront’s edge locations but without caching, ensuring dynamic content is always fresh.
KKey Concepts to Remember
AWS Global Accelerator uses static Anycast IP addresses.
It routes traffic over the AWS global network for improved performance.
Global Accelerator operates at Layer 4 (TCP/UDP).
It is suitable for dynamic content and non-HTTP/S applications.
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
AWS Global Accelerator uses static Anycast IP addresses.
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.
