You have a UDP load balancer that is created by an instance that is running an NGINX proxy. Your application performance management (APM) solution can detect failures in your load balancer instance and transfer the Elastic IP to a passive standby instance. Using the AWS CLI, which script do you program into your APM to move the Elastic IP?

•  A

aws ec2 disassociate-address --association-id eipassoc-2bebb712
aws ec2 associate-address --instance-id i-8b953 --allocation-id eipalloc-02d021a

•  B

aws ec2 release-address --association-id eipassoc-2bebb712
aws ec2 assign-address --instance-id i-8b953 --allocation-id eipalloc-02d021a

•  C

aws ec2 stop-instances --instance-ids i-8b953
wait 30
aws ec2 disassociate-address --association-id eipassoc-2bebb712
aws ec2 associate-address --instance-id i-8b953 --allocation-id eipalloc-02d021a
aws ec2 start-instances --instance-ids i-8b953

•  D

aws ec2 release-address --association-id eipassoc-2bebb712
aws ec2 associate-address --instance-id i-8b953 --allocation-id eipalloc-02d021a

Correct Answer:

•  A

aws ec2 disassociate-address --association-id eipassoc-2bebb712
aws ec2 associate-address --instance-id i-8b953 --allocation-id eipalloc-02d021a
