- A
Steady increase: Step scaling
Step scaling adjusts capacity incrementally in response to gradual load increases, making it ideal for steady growth.
- B
Sudden spikes: Simple scaling
Simple scaling immediately adjusts capacity by a fixed amount when a threshold is breached, suitable for sudden spikes.
- C
Cyclical patterns: Scheduled scaling
Scheduled scaling changes capacity at specific times, matching predictable cyclical patterns.
- D
Unpredictable bursts: Target tracking
Target tracking maintains a metric value (e.g., CPU utilization) by scaling dynamically, handling unpredictable bursts.
- E
Steady increase: Simple scaling
Why wrong: Simple scaling is for sudden spikes, not gradual increases. Step scaling is more appropriate for steady growth.
- F
Unpredictable bursts: Scheduled scaling
Why wrong: Scheduled scaling is for predictable patterns, not unpredictable bursts. Target tracking is a better fit.
SAA-C03 Design High-Performing Architectures Practice Question
This SAA-C03 practice question tests your understanding of design high-performing architectures. 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.
A company runs a stateless application tier behind an Application Load Balancer. Match each observed scaling pattern on the left to the best Auto Scaling strategy or metric on the right.
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
Steady increase: Step scaling
Steady increase is best handled by step scaling for gradual adjustments; sudden spikes use simple scaling for immediate action; cyclical patterns benefit from scheduled scaling; consistent low traffic may not need scaling; unpredictable bursts are managed by target tracking to maintain a metric; gradual decrease uses simple scaling to reduce capacity.
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 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.
