AWS Certified SysOps Administrator – Associate (legacy) — Question 334

An organization has configured Auto Scaling with ELB. There is a memory issue in the application which is causing CPU utilization to go above 90%. The higher
CPU usage triggers an event for Auto Scaling as per the scaling policy. If the user wants to find the root cause inside the application without triggering a scaling activity, how can he achieve this?

Answer options

• A. Stop the scaling process until research is completed
• B. It is not possible to find the root cause from that instance without triggering scaling
• C. Delete Auto Scaling until research is completed
• D. Suspend the scaling process until research is completed

Correct answer: D

Explanation

AWS Auto Scaling allows users to temporarily suspend and then resume one or more of the Auto Scaling processes, which is ideal for isolating and troubleshooting instances without triggering automated scaling actions. Deleting the Auto Scaling group or claiming it is impossible are incorrect, and 'suspend' is the precise AWS API action/terminology used for this purpose rather than 'stop'.
