ANS-C01 Network Management and Operations Practice Question
A company has a global application deployed across multiple AWS Regions. The application uses Amazon Route 53 latency-based routing. The network team wants to monitor the health of the application endpoints. They configure Route 53 health checks with fast interval (10 seconds) for each endpoint. After a few days, they notice an increase in costs. Which change will reduce costs while maintaining adequate health monitoring?
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
✓
Change the health check interval to standard (30 seconds).
Health checks are billed per check. Using a slower interval reduces the number of checks. Standard interval (30 seconds) is sufficient for most cases. Disabling end-to-end health checks or removing health checks would reduce functionality. Using CloudWatch alarms is additional cost.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable health checks and rely on Route 53 latency measurements.
Why it's wrong here
Disabling health checks removes endpoint health awareness, risking routing to unhealthy endpoints.
- ✓
Change the health check interval to standard (30 seconds).
Why this is correct
Standard interval reduces frequency and cost, still adequate for latency-based routing.
- ✗
Use CloudWatch alarms instead of Route 53 health checks.
Why it's wrong here
CloudWatch alarms are additional cost and do not integrate directly with Route 53 routing decisions.
- ✗
Remove health checks for endpoints that are in the same Region.
Why it's wrong here
This reduces coverage and may not be acceptable.
