You plan to run a Jenkins service requiring Amazon EFS as a shared, persistent storage attached to an Amazon ECS cluster and using AWS Fargate. What two statements are true in this context? (Select TWO).

Answer options:

A.You define the host and sourcePath parameters in the task definition.
B.You mount the Amazon EFS file system before the Docker daemon starts.
C.Amazon EFS file system support relies on platform version 1.3.0 or later.
D.The supervisor container is responsible for managing the Amazon EFS volume.
E.The supervisor container is visible in CloudWatch Container Insights.

Correct Answers: B, D
You must configure your container instance AMI to mount the Amazon EFS file system before the Docker daemon starts. When specifying Amazon EFS volumes in tasks using the Fargate launch type, Fargate creates a supervisor container responsible for managing the Amazon EFS volume. The supervisor container uses a small amount of the task`s memory.
Incorrect Answers:
Option A is incorrect because the host and sourcePath parameters are not supported for Fargate tasks.
Option C is incorrect because for tasks using the Fargate launch type, Amazon EFS file system support was added when using platform version 1.4.0 or later.
Option E is incorrect because the supervisor container is visible when querying the task metadata version 4 endpoint. But it is not visible in CloudWatch Container Insights.
