AWS - CloudWatch

A{"ScheduleExpression": "rate(5 minute)"}

B{"ScheduleExpression": "cron(0/5 * * * ? *)"}

C{"ScheduleExpression": "rate(5 min)"}

D{"ScheduleExpression": "cron(5 * * * ? *)"}

Step-by-Step Solution

Solution:

Step 1: Understand schedule syntax
EventBridge supports rate and cron expressions. For 5-minute intervals, cron syntax is cron(0/5 * * * ? *).
Step 2: Check each option
{"ScheduleExpression": "rate(5 minute)"} uses rate(5 minute) which is invalid syntax (must use 'minutes' plural). {"ScheduleExpression": "cron(0/5 * * * ? *)"} uses correct cron syntax for every 5 minutes. {"ScheduleExpression": "rate(5 min)"} uses 'min' which is invalid. {"ScheduleExpression": "cron(5 * * * ? *)"} triggers at minute 5 every hour, not every 5 minutes.
Final Answer:
{"ScheduleExpression": "cron(0/5 * * * ? *)"} -> Option B
Quick Check:
Cron for every 5 minutes = D [OK]

Quick Trick: Use cron(0/5 * * * ? *) for every 5 minutes [OK]
