AWS Certified SysOps Administrator – Associate (legacy) — Question 355

A user has created a VPC with a public subnet. The user has terminated all the instances which are part of the subnet. Which of the below mentioned statements is true with respect to this scenario?

Answer options

• A. The user cannot delete the VPC since the subnet is not deleted
• B. All network interface attached with the instances will be deleted
• C. When the user launches a new instance it cannot use the same subnet
• D. The subnet to which the instances were launched with will be deleted

Correct answer: B

Explanation

When EC2 instances are terminated, any primary Elastic Network Interfaces (ENIs) automatically created and attached to those instances are deleted by default. However, the subnet and the VPC are not automatically deleted and remain active, allowing the user to launch new instances into them at any time. Therefore, only the host-associated network interfaces are cleaned up, while the underlying network configuration remains intact.
