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: uses static Anycast IP addresses as fixed entry points.. 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 telemetry pipeline 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? The architecture review board prefers a managed AWS-native control.
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 is the correct choice because it uses the AWS global network and Anycast IP addresses to route user traffic to the optimal Application Load Balancer endpoint, reducing latency for global users without caching dynamic responses. Unlike CloudFront, Global Accelerator does not cache content; it simply optimizes the network path, making it ideal for dynamic or real-time applications where caching is not acceptable. It is a managed AWS-native service that aligns with the architecture review board's preference.
Key principle: Uses static Anycast IP addresses as fixed entry points.
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
Uses static Anycast IP addresses as fixed entry points.
✗
S3 Cross-Region Replication
Why it's wrong here
CRR replicates objects and does not optimize dynamic application routing.
✗
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.
✗
AWS Backup cross-Region copy
Why it's wrong here
Backup copies do not reduce live user latency.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse CloudFront with Global Accelerator, assuming that any CDN-like service is the answer for latency reduction, but CloudFront's caching behavior makes it unsuitable for dynamic content that must not be cached.
Detailed technical explanation
How to think about this question
AWS Global Accelerator leverages Anycast IP addresses that announce the same IP from multiple AWS edge locations, directing traffic to the nearest healthy endpoint via the AWS global backbone. This avoids the public internet's variable latency and packet loss, providing up to 60% improvement in first-byte latency for global users. Under the hood, it uses the TCP termination at the edge and maintains persistent connections to the ALB, which also offloads connection management from the application.
KKey Concepts to Remember
Uses static Anycast IP addresses as fixed entry points.
Routes traffic over the AWS global network for performance improvement.
Operates at Layer 4 (TCP/UDP) and Layer 7 (HTTP/S).
Ideal for non-cacheable, dynamic content and 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
Uses static Anycast IP addresses as fixed entry points.
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.
