This ANS-C01 practice question tests your understanding of network design. 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 designing a multi-Region active-active application using Application Load Balancers (ALBs) behind AWS Global Accelerator. They require that traffic from a specific client IP address is always routed to the same AWS Region for session persistence. Which Global Accelerator feature should be used?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "always"
Why it matters: Absolute qualifier. An answer using 'always' is only correct if there are genuinely no exceptions — absolute statements are often wrong in networking.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable client IP address affinity (sticky sessions).
Option B is correct because Global Accelerator's sticky sessions (client IP address affinity) ensure that traffic from a given client IP is routed to the same endpoint for a set duration. Option A is incorrect because health checks determine endpoint health but do not enforce stickiness. Option C is incorrect because traffic dials control traffic distribution percentages but cannot pin a client to one endpoint. Option D is incorrect because endpoint weights distribute traffic proportionally but do not guarantee stickiness.
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.
✗
Configure health checks on the endpoints.
Why it's wrong here
Health checks detect endpoint health, they do not provide session stickiness.
✓
Enable client IP address affinity (sticky sessions).
Why this is correct
Client IP address affinity ensures requests from a given client IP are consistently routed to the same endpoint.
Clue confirmation
The clue word "always" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Assign endpoint weights to each ALB.
Why it's wrong here
Endpoint weights distribute traffic proportionally but do not guarantee a client sticks to one endpoint.
✗
Set traffic dials to 100% for both Regions.
Why it's wrong here
Traffic dials control the percentage of traffic sent to each endpoint group, not per-client stickiness.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
