How can the user ensure that this temporary event does not result in scaling?

A user is aware that a huge download is occurring on his instance. He has already set the Auto Scaling 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?
A . The network I/O are not affected during data download
B . The policy cannot be set on the network I/O
C . There is no way the user can stop scaling as it is already configured
D . Suspend scaling

Answer: D

Explanation:

The user may want to stop the automated scaling processes on the Auto Scaling groups either to perform manual operations or during emergency situations. To perform this, the user can suspend one or more scaling processes at any time. Once it is completed, the user can resume all the suspended processes.
