Which of the below mentioned statements is true with respect to this scenario?
The subnet to which the instances were launched with will be deleted
When the user launches a new instance it cannot use the same subnet
The user cannot delete the VPC since the subnet is not deleted
Secondary network interfaces attached to the terminated instances may persist.
Explanations:
A subnet is not deleted automatically when instances are terminated. The subnet remains available unless explicitly deleted by the user.
The user can launch a new instance in the same subnet even if the previous instances were terminated. The subnet remains available.
The VPC can still be deleted as long as the subnet is not explicitly deleted. The existence of the subnet does not prevent VPC deletion.
Secondary network interfaces (ENIs) attached to terminated instances may persist, and the user may need to delete them manually if no longer needed.
I estimate that the answer is:
Secondary network interfaces attached to the terminated instances may persist.
