SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 is migrating a legacy on-premises web application to AWS. The application consists of a stateless web tier and a stateful application tier that stores session data in memory. The company wants to achieve high availability and elasticity. The migration must minimize code changes. The solutions architect proposes using an Application Load Balancer (ALB) with sticky sessions and an Auto Scaling group for the web tier. For the application tier, they plan to use an ALB with sticky sessions and an Auto Scaling group. During testing, users report that they are unexpectedly logged out and lose session data. The application logs show that requests from the same user are being sent to different instances. Which change should the solutions architect make to resolve this issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Verify that the ALB stickiness configuration is enabled and the cookie duration is appropriate.
Sticky sessions rely on the ALB cookie. If the cookie is not set or is not being sent back, the load balancer cannot maintain session affinity. Checking the ALB stickiness configuration ensures that the duration and cookie settings are correct. Option A is wrong because moving sessions to ElastiCache requires code changes, which the company wants to minimize. Option B is wrong because cross-zone load balancing distributes traffic evenly but does not affect stickiness. Option D is wrong because disabling stickiness would worsen the problem.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Disable sticky sessions and use a Network Load Balancer instead.
Why it's wrong here
NLB does not support sticky sessions by default and would cause more issues.
✗
Migrate session state to Amazon ElastiCache for Redis.
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.
