If I write the below command, what does it do?
ec2-run ami-e3a5408a -n 20 -g appserver
Start twenty instances as members of appserver group.
Creates 20 rules in the security group named appserver
Terminate twenty instances as members of appserver group.
Start 20 security groups
Explanations:
The commandec2-runis used to launch EC2 instances, and the parameters indicate starting 20 instances from the specified AMI (ami-e3a5408a) and associating them with the security group named appserver.
The command does not create security group rules; it is intended for launching instances. Security groups can be associated but are not created with this command.
The command is for starting instances, not terminating them. There is no indication of termination in the syntax provided.
The command does not create security groups; it is focused on launching instances. The mention of security groups in the context of this command does not relate to creating them.
As far as I’m aware, the answer is:
Start twenty instances as members of appserver group.
