The answer is to set the traffic dial for each endpoint group to a value that reflects the desired distribution, configure health checks on endpoints for fast failover, and adjust traffic dials to fine-tune the distribution. These three steps work together because Global Accelerator uses traffic dials as a percentage-based control to route traffic across multiple endpoint groups, while health checks enable the accelerator to detect unhealthy endpoints and reroute traffic instantly. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of how Global Accelerator distributes traffic using endpoint groups and traffic dials rather than weighted routing, which is a common trap—remember that Global Accelerator relies on proximity and dials, not weights. A key memory tip is to think of traffic dials as volume knobs for each region: turn the dial up to send more traffic, and rely on health checks as the automatic failover switch.
ANS-C01 Network Management and Operations Practice Question
This ANS-C01 practice question tests your understanding of network management and operations. 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. 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 using AWS Global Accelerator to improve performance for a global application. The application uses an Application Load Balancer (ALB) in each region. The network team wants to ensure that traffic is distributed evenly across regions and that failover happens quickly. Which THREE steps should the team take? (Select THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure multiple endpoint groups, one per region, and set traffic dials to distribute load
Options A, C, and D are correct. A: Multiple endpoint groups with traffic dials allow distributing traffic across regions. C: Health checks on endpoints ensure quick failover. D: Adjusting traffic dials can fine-tune distribution. Option B is wrong because weighted routing is not a Global Accelerator feature; it uses proximity. Option E is wrong because client IP preservation is not related to traffic distribution.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Enable client IP address preservation on the Global Accelerator
Why it's wrong here
Client IP preservation does not affect traffic distribution.
✗
Use Route 53 weighted routing in front of Global Accelerator
Why it's wrong here
Global Accelerator uses its own routing; Route 53 not needed.
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.

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.

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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.

Variation 1. A company uses AWS Global Accelerator to improve performance for a global application. The application is deployed in two AWS regions behind Network Load Balancers. Users in Asia report high latency even though the accelerator should route them to the nearest endpoint. What is the most likely reason?
medium
✓ A.The endpoint in the closer region is marked unhealthy
B.Traffic Dial is set to 100% for the distant region
C.The accelerator is configured with on-premises endpoints
D.Client affinity is set to source IP
Why A: Option A is correct because if the endpoints are unhealthy, Global Accelerator will route traffic to the other region. Option B is incorrect because Traffic Dial can shift traffic but does not cause high latency. Option C is incorrect because client affinity does not affect latency. Option D is incorrect because Global Accelerator endpoints are typically in AWS, not on-premises.
Variation 2. A company is using AWS Global Accelerator to improve performance for a web application hosted in two AWS Regions. The application uses an Application Load Balancer (ALB) in each region. The company wants to ensure that traffic is directed to the closest healthy endpoint. Which routing configuration should be used?
easy
✓ A.Global Accelerator endpoint groups with health checks and traffic dials
B.Global Accelerator with weighted endpoint groups
C.Route 53 latency-based routing with health checks
D.Route 53 geolocation routing with Global Accelerator
Why A: Option B is correct because Global Accelerator uses Anycast IPs and directs traffic to the nearest healthy endpoint based on latency and health checks. Option A is wrong because Route 53 latency routing is not used with Global Accelerator. Option C is wrong because Global Accelerator does not use weighted routing. Option D is wrong because geolocation routing is not the default; Global Accelerator uses proximity.
