Answers
D.
ec2-net-utils identifies network interfaces when they are attached, detached, or reattached to a running instance.
Suggested answer: C

Explanation:

Each instance in a VPC has a default elastic network interface (the primary network interface) that is assigned a private IP address from the IP address range of your VPC. You cannot detach a primary network interface from an instance. You can create and attach additional elastic network interfaces. Amazon Linux AMIs may contain additional scripts installed by AWS, known as ec2-net-utils. One of the components that is part of ec2-net-utils used with ENI's is ec2ifscan. Its function is to check for network interfaces that have not been configured and configure them.
