Topic #: 1
[All AWS-SysOps Questions]

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

Suggested Answer: D 🗳️
Section: (none)
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. A user can create a 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.

I go with A By default, all AWS accounts are limited to five (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. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html

i agree with you, partial, but not throw an error ? after throwing an error, you can request more ElasticIPs in your Region.
