Default VPC IP Address Assignment on Amazon EC2 Instances

What are the two IP addresses assigned to Amazon EC2 instances in a default VPC?

A. A Public IP Address & Secret IP Address

B. An Elastic IP Address & Public IP Address

C. An IPv6 Address and Elastic IP Address

D. A Private IP Address & Public IP Address

Answer:

The two IP addresses assigned to Amazon EC2 instances in a default VPC are:

D. A Private IP Address & Public IP Address

In a default Virtual Private Cloud (VPC) on Amazon Web Services (AWS), every Amazon Elastic Compute Cloud (EC2) instance launched is assigned two IP addresses. These are: a Private IP Address & Public IP Address.

The Private IP Address is used for communication within the VPC network, allowing instances to communicate internally. On the other hand, the Public IP Address enables communication with the internet, making it accessible from outside the VPC.

Elastic IP addresses and IPv6 addresses need specific configuration and are not automatically assigned at launch. A Public IP Address is only assigned if the instance requires internet communication.
