What should the SysOps administrator do to resolve this error?
Add an additional CIDR block to the VPC.
Launch the EC2 instances in a different Availability Zone.
Launch new EC2 instances in another VPC.
Use Service Quotas to request an EC2 quota increase.
Explanations:
Adding an additional CIDR block to the VPC would not resolve the InstanceLimitExceeded error. This error is due to a quota limit on EC2 instances, not related to the VPC’s CIDR block.
Launching EC2 instances in a different Availability Zone would not resolve the InstanceLimitExceeded error. The error is a result of hitting an instance limit, not a problem with Availability Zones.
Launching new EC2 instances in another VPC won’t help. The issue is related to EC2 instance limits, not VPCs themselves.
Using Service Quotas to request an EC2 quota increase is the correct solution. InstanceLimitExceeded errors occur when the account reaches the maximum allowed EC2 instances, and requesting a quota increase resolves this issue.
I map out that the answer is:
Use Service Quotas to request an EC2 quota increase.
