Question 342 of 1,621
ANS-C01 Network Management and Operations Practice Question
A company has a global application deployed across multiple AWS regions. The application uses Application Load Balancers (ALBs) and Auto Scaling groups. The network team wants to route traffic to the nearest region based on latency, and also wants to failover to another region if the primary region becomes unhealthy. Which THREE services should be used together to achieve this? (Choose THREE.)

Correct answer & explanation
✓
Amazon Route 53 latency-based routing
Route 53 latency-based routing (B) directs traffic to the region with the lowest latency. CloudWatch alarms (C) can monitor health metrics like ALB 5xx errors or instance health to detect regional failure. AWS Lambda (D) can be triggered by CloudWatch alarms to automatically update Route 53 records (e.g., change failover records or disable unhealthy records) to redirect traffic to a healthy region. Option A (CloudFront with origin failover) is for content delivery and static origin failover, not dynamic routing based on latency and regional health. Option E (Global Accelerator) provides anycast IP and global traffic optimization but does not natively support latency-based routing to the nearest region with automatic failover based on CloudWatch alarms in the same manner; it has different health check mechanisms and is not the standard combination described.
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 origin failover
Why it's wrong here
Not for regional routing.
- ✓
Amazon Route 53 latency-based routing
Why this is correct
Routes based on latency.
- ✓
Amazon CloudWatch alarms to detect regional health
Why this is correct
Triggers failover.
- ✓
AWS Lambda to update Route 53 records on failover
Why this is correct
Automates DNS change.
- ✗
AWS Global Accelerator
Why it's wrong here
Uses anycast, not Route 53.

Same concept, more angles
1 more way this is tested on ANS-C01
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company has a global application deployed across multiple AWS Regions. Users are routed to the nearest Region using Amazon Route 53. The application uses an Application Load Balancer in each Region. The network team wants to ensure that traffic is always routed to a healthy Region in case of a Regional failure. Which Route 53 routing policy should be used?
hard- ✓ A.Latency-based routing with health checks
- B.Weighted routing
- C.Simple routing
- D.Failover routing
Why A: Latency-based routing with health checks. This policy routes traffic to the region with the lowest latency and can automatically failover to a healthy region if health checks fail. Option B (Weighted routing) distributes traffic based on weights, not latency, and does not provide automatic failover based on health. Option C (Simple routing) routes to a single resource and cannot automatically failover. Option D (Failover routing) is a primary/backup setup, not latency-based, so it doesn't consider latency.
