Which of the following is the correct way to specify a CloudWatch alarm threshold for CPU utilization above 80%?
A"Threshold": "<=80"
B"Threshold": 80, "ComparisonOperator": "LessThanThreshold"
C"Threshold": 80, "ComparisonOperator": "LessThanOrEqualToThreshold"
D"Threshold": 80, "ComparisonOperator": "GreaterThanThreshold"
Step-by-Step Solution
Solution:

  1. Step 1: Understand threshold syntax

    CloudWatch alarms use a numeric Threshold value and a separate ComparisonOperator like GreaterThanThreshold, LessThanThreshold.

  2. Step 2: Choose operator for above 80%

    To alert when CPU is above 80%, use "Threshold": 80, "ComparisonOperator": "GreaterThanThreshold".

  3. Final Answer:

    "Threshold": 80, "ComparisonOperator": "GreaterThanThreshold" -> Option D

  4. Quick Check:

    Above 80% = GreaterThanThreshold(80) [OK]
Quick Trick: Use GreaterThanThreshold for above threshold [OK]
Common Mistakes:
MISTAKES
  • Using < instead of > for above threshold
  • Using = which triggers only at exact value
  • Confusing <= with above threshold
