A user has launched 5 instances in EC2-CLASSIC and attached 5 elastic IPs to the five different instances in the
US East region. The user is creating a VPC in the same region. The user wants to assign an elastic IP to the VPC
instance. How can the user achieve this?
A.
The user has to request AWS to increase the number of elastic IPs associated with the account
B.
AWS allows 10 EC2 Classic IPs per region; so it will allow to allocate new Elastic IPs to the same
region
C.
The AWS will not allow to create a new elastic IP in VPC; it will throw an error
D.
The user can allocate a new IP address in VPC as it has a different limit than EC2
Explanation:
subnet with VPC and launch instances inside that subnet. A user can have 5 IP addresses per region with EC2
Classic. The user can have 5 separate IPs with VPC in the same region as it has a separate limit than EC2 Classic.

A I believe.
There is a limit of 5 EIP per region. You must request for this to be increased.

I would go for D:)

Elastic IP addresses per region

This is the limit for the number of VPC Elastic IP addresses you can allocate within a region. This is a separate limit from the Amazon EC2 Elastic IP address limit. If you need to increase this limit, submit a request.

A is right
Elastic IP Address Limit
By default, all AWS accounts are limited to 5 Elastic IP addresses per region, because public (IPv4) Internet addresses are a scarce public resource. We strongly encourage you to use an Elastic IP address primarily for the ability to remap the address to another instance in the case of instance failure, and to use DNS hostnames for all other inter-node communication.
If you feel your architecture warrants additional Elastic IP addresses, please complete the Amazon EC2 Elastic IP Address Request Form. We will ask you to describe your use case so that we can understand your need for additional addresses.
