AWS Certified Solutions Architect – Professional — Question 104

A user has created a launch configuration for Auto Scaling where CloudWatch detailed monitoring is disabled. The user wants to now enable detailed monitoring.
How can the user achieve this?

Answer options

• A. Update the Launch config with CLI to set InstanceMonitoringDisabled = false
• B. The user should change the Auto Scaling group from the AWS console to enable detailed monitoring
• C. Create a new Launch Config with detail monitoring enabled and update the Auto Scaling group
• D. Update the Launch config with CLI to set InstanceMonitoring.Enabled = true

Correct answer: C

Explanation

The correct answer is C because to enable detailed monitoring, a new launch configuration must be created with that setting, as existing launch configurations cannot be modified. Options A and D suggest modifying the existing configuration, which is not possible, while option B does not address the need for a new launch configuration.
