This ANS-C01 practice question tests your understanding of network design. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 application with active-active configuration. They need a global DNS service that can route users to the nearest healthy endpoint and automatically failover to another region if an endpoint becomes unhealthy. Which AWS service should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon Route 53 with latency-based routing and health checks
Option A is correct because Amazon Route 53 with latency-based routing can route to the region with the lowest latency, and health checks can failover. Option B is wrong because AWS Global Accelerator provides static IP addresses and improves performance, but it does not provide DNS-level routing with health-based failover. Option C is wrong because CloudFront is a CDN. Option D is wrong because ELB is regional.
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.
✗
Amazon CloudFront
Why it's wrong here
CloudFront is a content delivery network, not a DNS routing service.
✗
Elastic Load Balancer
Why it's wrong here
ELBs are regional and do not provide global routing or failover across regions.
✓
Amazon Route 53 with latency-based routing and health checks
Why this is correct
Route 53 latency routing directs traffic to the region with the lowest latency, and health checks enable failover.

✗
AWS Global Accelerator
Why it's wrong here
Global Accelerator uses anycast IPs and can route to healthy endpoints, but it does not provide DNS-level routing.
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.
