Question 480 of 1,621
ANS-C01 Network Implementation Practice Question
A company has deployed an application across multiple AWS Regions using Application Load Balancers (ALBs). The company wants to route traffic to the nearest healthy endpoint using latency-based routing. Which AWS service should be used to distribute traffic across the ALBs?
⚠ Common exam trap
Many candidates confuse AWS Global Accelerator's Anycast-based performance routing with latency-based routing, but Global Accelerator uses static IPs and the AWS backbone for geographic proximity, not real-time user-to-endpoint latency measurements like Route 53 latency policy.
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
✓
Amazon Route 53 with latency routing policy.
Amazon Route 53 with a latency routing policy is the correct choice because it directs traffic to the ALB endpoint that provides the lowest latency for the end user, based on measured round-trip times between the user and each AWS Region. This aligns with the requirement to route traffic to the nearest healthy endpoint using latency-based routing, as Route 53 evaluates health checks on the ALBs and only considers healthy endpoints when determining the lowest 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.
- ✗
Amazon CloudFront with multiple origins.
Why it's wrong here
CloudFront is a CDN, not a global traffic router for ALBs.
- ✗
AWS Network Load Balancer with cross-zone load balancing.
Why it's wrong here
NLB operates within a single region and does not route across regions.
- ✓
Amazon Route 53 with latency routing policy.
Why this is correct
Route 53 latency routing routes traffic based on the lowest latency between the client and the endpoint.
- ✗
AWS Global Accelerator.
Why it's wrong here
Global Accelerator uses Anycast and directs traffic to the nearest edge location, but not specifically latency-based routing to ALBs.
