AWS Certified SysOps Administrator – Associate (legacy) — Question 800

A user is aware that a huge download is occurring on his instance. He has already set the Auto Scal-ing policy to increase the instance count when the network I/
O increases beyond a certain limit. How can the user ensure that this temporary event does not result in scaling?

Answer options

• A. The policy cannot be set on the network I/O
• B. There is no way the user can stop scaling as it is already configured
• C. The network I/O are not affected during data download
• D. He can suspend scaling temporarily

Correct answer: D

Explanation

AWS Auto Scaling allows users to temporarily suspend and then resume one or more of the Auto Scaling processes for their Auto Scaling group, which is highly useful for temporary events or troubleshooting. Suspending the scaling process prevents the group from launching or terminating instances even if the network I/O thresholds are crossed. Other options are incorrect because network I/O can be used as a metric, downloads absolutely affect network I/O, and scaling processes can indeed be paused.
