ANS-C01 Network Management and Operations Practice Question

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?

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

The endpoint in the closer region is marked unhealthy

If the endpoint in the closer region is marked unhealthy, Global Accelerator will automatically route traffic to the next nearest healthy endpoint, which may be in a distant region, causing high latency. Option B is incorrect because if Traffic Dial were set to 100% for the distant region, traffic would be intentionally routed there, so users would not expect routing to the nearest endpoint. Option C is incorrect because on-premises endpoints are not typical for Global Accelerator, and even if used, they would not cause high latency specifically for Asian users if the closer region has healthy endpoints. Option D is incorrect because client affinity affects stickiness, not overall latency; it would not cause all Asian users to experience high latency.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The endpoint in the closer region is marked unhealthy

    Why this is correct

    Global Accelerator routes traffic away from unhealthy endpoints.

  • Traffic Dial is set to 100% for the distant region

    Why it's wrong here

    Traffic Dial controls traffic distribution, not latency.

  • The accelerator is configured with on-premises endpoints

    Why it's wrong here

    On-premises endpoints are not supported.

  • Client affinity is set to source IP

    Why it's wrong here

    Client affinity does not cause high latency.
