Which AWS instance address has the following characteristics? :”If you stop an instance, its Elastic IP address is
unmapped, and you must remap it when you restart the instance.”
A.
Both A and B
B.
None of these
C.
VPC Addresses
D.
EC2 Addresses
Explanation:
This question is missing some information.
Yes, fluffy one. I would go for D.
I’d go with D as well.
B. None of these.
D will applicable only when EC2-classic type in use .
D

Stopping an instance
EC2-Classic
If you stop an instance, its Elastic IP address is disassociated, and you must reassociate the Elastic IP address when you restart the instance.
EC2-VPC
If you stop an instance, its Elastic IP address remains associated.
EC2-Classic: We disassociate any Elastic IP address that’s associated with the instance. You’re charged for Elastic IP addresses that aren’t associated with an instance. When you restart the instance, you must associate the Elastic IP address with the instance; we don’t do this automatically.
D
D is the right answer.
See http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html#VPC_EIP_EC2_Differences
Stopping an instance:
– If you stop an instance, its Elastic IP address is disassociated, and you must reassociate the Elastic IP address when you restart the instance.
– If you stop an instance, its Elastic IP address remains associated.
question should be like this:
Which AWS instance address has the following characteristics? :” If you stop an instance, its Elastic IP address is unmapped, and you must remap it when you restart the instance.”
A VPC Addresses
B EC2 Addresses
C None of these
D Both A and B
Answer: B
I agree with the answer. A
I think the answer is A because we do not need to remap the EIP, we need to associate it.
The choices is strange. It will be more reasonable like this:
A. EC2-VPC
B. EC2-Classic
C. Both A and B
D. None of these
http://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/Stop_Start.html
D:
Classic EC2- If you stop an instance, its Elastic IP address is disassociated, and you must reassociate the Elastic IP address when you restart the instance.
So Ans is D
D.
EC2 Addresses
Just tested .. EC2 Elastic IP on a T2 instance .. stopped .. started .. EIP remained Hope I don’t get this is in the exam
None of these.
If an Ec2 is stopped and started the EIP is not disassociated or unmapped.
D
If you stop an instance, its Elastic IP address is disassociated, and you must reassociate the Elastic IP address when you restart the instance.
If you stop an instance, its Elastic IP address remains associated.
