Exam AWS Certified SysOps Administrator - Associate topic 1 question 102 discussion

Its AB. E is relevant for InstanceLimitExceeded not InsufficientInstanceCapacity.

https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/troubleshooting-launch.html#troubleshooting-launch-capacity Solution To resolve the issue, try the following: Wait a few minutes and then submit your request again; capacity can shift frequently. Submit a new request with a reduced number of instances. For example, if you're making a single request to launch 15 instances, try making 3 requests for 5 instances, or 15 requests for 1 instance instead. ****If you're launching an instance, submit a new request without specifying an Availability Zone. ****If you're launching an instance, submit a new request using a different instance type (which you can resize at a later stage). For more information, see Change the instance type. If you are launching instances into a cluster placement group, you can get an insufficient capacity error. For more information, see Placement group rules and limitations.

Cause If you get this error when you try to launch an instance or restart a stopped instance, AWS does not currently have enough available On-Demand capacity to fulfill your request.
