A SysOps Administrator is creating additional Amazon EC2 instances and receives an InstanceLimitExceeded error. What is the cause of the issue and how can it be resolved?
A.
The Administrator has requested too many instances at once and must request fewer instances in batches.
B.
The concurrent running instance limit has been reached, and an EC2 limit increase request must be filed with AWS Support.
C.
AWS does not currently have enough available capacity and a different instance type must be used.
D.
The Administrator must specify the maximum number of instances to be created while provisioning EC2 instances.
It's important to note that increasing the EC2 instance limit may take some time, depending on the review process by AWS Support. Planning ahead and considering future capacity requirements can help avoid running into instance limit constraints.
B is the Answer
InstanceLimitExceeded error means you have reached the limit of 20 instances in a given region.
2 possibilities to fix the error:
- launch your instances in another region or ask AWS support to increase the limit
easy to get confused with C, InsufficientInstanceCapacity wich means that AWS does not have enough available capacity at the time you've made your request
Answer "B".
'InstanceLimitExceeded' error means that you have reached your limit of max number of instances in a given region. The default instances limit per region is 20
So, either we should launch the instance in a different region (or) we should request AWS to increase our limit in the specific region.
Note: This is no longer valid; as the limit is now calculated using the number of vCPU's consumed in a given region instead of number of instances. The default vCPU's allowed per region is 32 vCPUs
Answer is B:
InstanceLimitExceeded error:
- YOU HAVE REACHED THE LIMIT ON THE NUMBER OF INSTANCES YOU CAN LAUNCH IN A REGION
- AWS default limits on the number of instances you can run on a per-region basis - 20 by default.
- You can request an increase in a region per request basis.
