This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: Understand CloudWatch monitoring
Prompt focus: By default, Amazon EC2 sends basic monitoring metrics to CloudWatch at which interval?
Why the correct answer works
Every 5 minutes
Basic EC2 monitoring sends metrics to CloudWatch every 5 minutes.
Why the tempting wrong answer fails
The tempting wrong answer usually loses because it skips the key condition, priority, or evidence in the prompt.
Plain-language takeaway
Basic monitoring for EC2 delivers metrics to CloudWatch at five-minute intervals. Enabling detailed monitoring reduces this to one-minute intervals for an additional cost.
Simple analogy
Think of understand cloudwatch monitoring like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
