You are working with an architecture team and several cloud engineers. The project requires containerization, and you are responsible for maintaining the Amazon ECS tasks. What concepts are correct when it comes to task definitions?

Answer options:

A.Name, image, memory, and port mapping are task definition parameters required and used in most container definitions.
B.If the network mode is a bridge, the task utilizes Docker`s built-in virtual network which runs inside each container instance.
C.If using the Fargate launch type, the awsvpc network mode is no longer required.
D.Docker for Windows offers host and awsvpc network modes as the highest networking performance so you can take advantage of dynamic host port mappings.

Correct Answer: B
The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. The default Docker network mode is bridge. If the network mode is a bridge, the task utilizes Docker`s built-in virtual network which runs inside each container instance.
Incorrect Answers:
Option A is incorrect because only name and image are required as task definition parameters.
Option C is incorrect because If using the Fargate launch type, the awsvpc network mode is required. If using the EC2 launch type, the allowable network mode depends on the underlying EC2 instance`s operating system.
Option D is incorrect because Docker for Windows uses a different network mode (known as NAT) than Docker for Linux. When you register a task definition with Windows containers, you must not specify a network mode.
