AWS - Route 53

A Route 53 health check is configured to probe an endpoint every 30 seconds with a failure threshold of 3. How long will it take for Route 53 to mark the endpoint as unhealthy after continuous failures?

A90 seconds

B60 seconds

C120 seconds

D30 seconds

Step-by-Step Solution

Solution:

Step 1: Understand Health Check Frequency
The health check runs every 30 seconds.
Step 2: Calculate Total Time to Mark Unhealthy
With a failure threshold of 3, Route 53 requires 3 consecutive failures: 3 x 30 seconds = 90 seconds.
Final Answer:
90 seconds -> Option A
Quick Check:
Failure threshold x interval seconds = time to unhealthy [OK]

Quick Trick: Multiply interval by failure threshold for unhealthy time [OK]

Common Mistakes:

Using failure threshold minus one in calculation
Confusing interval with timeout
Assuming immediate unhealthy status after first failure
