D.
Use a Classic Load balancer and terminate the SSL connection at the EC2 Instances
Answers
D.
Use a Classic Load balancer and terminate the SSL connection at the EC2 Instances
Suggested answer: D

Explanation:

Since there are applications which work on legacy protocols, you need to ensure that the ELB can be used at the network layer as well and hence you should choose the Classic ELB. Since the traffic needs to be secure till the EC2 Instances, the SSL termination should occur on the Ec2 Instances.

Option A and C are invalid because you need to use a Classic Load balancer since this is a legacy application. Option B is incorrect since encryption is required until the EC2 Instance For more information on HTTPS listeners for classic load balancers, please refer to below URL https://docs.aws.ama20n.com/elasticloadbalancing/latest/classic/elb-https-load-balancers.htmllThe correct answer is: Use a Classic Load balancer and terminate the SSL connection at the EC2InstancesSubmit your Feedback/Queries to our Experts
