You are setting up your first Amazon Virtual Private Cloud (Amazon VPC) so you decide to use the VPC wizard in the AWS console to help make it easier for you.

Which of the following statements is correct regarding instances that you launch into a default subnet via the VPC wizard?
A . Instances that you launch into a default subnet receive a public IP address and 10 private IP addresses.
B . Instances that you launch into a default subnet receive both a public IP address and a private IP address.
C . Instances that you launch into a default subnet don’t receive any ip addresses and you need to define them manually.
D . Instances that you launch into a default subnet receive a public IP address and 5 private IP addresses.

Answer: B

Explanation:

Instances that you launch into a default subnet receive both a public IP address and a private IP address.

Instances in a default subnet also receive both public and private DNS hostnames. Instances that you launch into a nondefault subnet in a default VPC don’t receive a public IP address or a DNS hostname. You can change your subnet’s default public IP addressing behavior.
