elastic IP question

[peter-cooke]

the question

A Solutions Architect needs to create a publicly accessible EC2 instance by using an Elastic IP (EIP) address and generate a report on how much it will cost to use that EIP.

Which of the following statements is correct regarding the pricing of EIP?

the question answer :There is no cost if the instance is running and it has only one associated EIP.

in reality you are charged a per hour fee for any IP not attached to a running elastic IP. You are charged for instance storage plus a per hour fee for EIP. see https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html#eip-pricing

EIP is not charged a fee only when it is attached to a running instance

Hello Peter,

Yes, EIP attached to a running instance is free. However, you get billed for unused EIPs. Hence the answer, There is no cost if the instance is running and it has only one associated EIP. is correct.

Hmm, I don’t see anything wrong with this question. But please do let me know why you think otherwise.

Thanks & Regards,

That is not correct. are charged for all elastic IP’s attached to stopped instances. Otherwise I would not have received a bill for EIB I left on a stopped instance for a month.

per AWS (stopped instance is not running clearly the second condition is not met and therefor you will be charged:

——————-from AWS below here on —————-

An Elastic IP address doesn’t incur charges as long as all the following conditions are true:

The Elastic IP address is associated with an EC2 instance.

The instance associated with the Elastic IP address is running.

The instance has only one Elastic IP address attached to it.

The Elastic IP address is associated with an attached network interface, such as a Network Load Balancer or NAT gateway.

dam I read stopped and stopped and stopped instance. where did the running instance come from.

I see. So you got a little confused about the wordings. Don’t worry, it happens. Just don’t let it happen on the actual exam. 😃

Goodluck!
