The correct answer is to use AWS Global Accelerator with endpoints as the Application Load Balancers in each Region. This configuration achieves the lowest possible latency because Global Accelerator routes traffic over the AWS global network using anycast IPs, bypassing the public internet and automatically directing users to the nearest healthy endpoint. For the ANS-C01 exam, this question tests your understanding of how Global Accelerator optimizes latency-sensitive TCP traffic across multiple Regions, contrasting it with Route 53 latency routing, which still relies on public internet hops, and CloudFront, which only supports HTTP/HTTPS. A common trap is assuming a Network Load Balancer can handle multi-region routing, but it lacks Global Accelerator’s anycast and regional endpoint failover. Remember the memory tip: “Anycast ALBs beat public-path DNS” — Global Accelerator’s anycast IPs always provide the shortest path over AWS’s private backbone for TCP traffic.
ANS-C01 Network Implementation Practice Question
This ANS-C01 practice question tests your understanding of network implementation. 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 deploying a latency-sensitive application across two AWS Regions using Application Load Balancers (ALBs) and AWS Global Accelerator. The application uses TCP port 8443. Which configuration ensures the lowest possible latency for global users?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Global Accelerator with endpoints as the ALBs in each Region.
Option D is correct because Global Accelerator uses the AWS global network and anycast IPs, reducing latency. Option A is wrong because Route 53 with latency routing still uses public internet. Option B is wrong because CloudFront is for HTTP/HTTPS, not TCP. Option C is wrong because Network Load Balancer does not have multi-region capability.
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.
✗
Use Amazon CloudFront with the ALBs as origins.
Why it's wrong here
CloudFront supports only HTTP/HTTPS, not TCP 8443.
✗
Use Amazon Route 53 latency-based routing with ALB endpoints in each Region.
Why it's wrong here
Route 53 does not optimize network path; uses public internet.
✓
Use AWS Global Accelerator with endpoints as the ALBs in each Region.
Why this is correct
Global Accelerator uses anycast and AWS backbone for lower latency.

✗
Deploy a Network Load Balancer in each Region and use Route 53 geoproximity routing.
Why it's wrong here
Still uses public internet; NLB is single-region.
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 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 is deploying a latency-sensitive application across multiple AWS Regions. They want to use the AWS global network to route traffic to the nearest edge location for fast content delivery. Which service should they use?
hard
✓ A.AWS Global Accelerator
B.Amazon Route 53
C.AWS Direct Connect
D.Amazon CloudFront
Why A: The correct answer is A because AWS Global Accelerator uses the AWS global network to direct traffic to the optimal endpoint, improving latency. Option B (CloudFront) is a CDN for caching static content. Option C (Route 53) is a DNS service. Option D (Direct Connect) is for dedicated connections.
