You are a developer who is supporting a containerized application. You are told to set up dynamic port mapping for Amazon ECS and load balancing. What statement is true in this case?

Answer options:

A.Classic Load Balancer allows you to run multiple copies of a task on the same instance.
B.Application Load Balancer uses static port mapping on a container instance.
C.After creating an Amazon ECS service, you add the load balancer configuration.
D.If dynamic port mapping is set up correctly, then you see the registered targets and the assigned port for the task.

Correct Answer: D
This is just the clear result of having set up dynamic port mapping correctly since you can see the registered targets in the target group used to route requests and the assigned port for the task.
Incorrect Answers:
Option A is incorrect because Classic Load Balancer actually doesn’t allow you to run multiple copies of a task on the same instance.
Option B is incorrect because Application Load Balancer uses dynamic port mapping. So you can run multiple tasks from a single service on the same container instance.
Option C is incorrect because you can add a load balancer only during the creation of the service. You can`t add, remove, or change the load balancer configuration of an existing service.
