AWS (Amazon Web Services) Certification Practice Exam

What is required when performing a Fargate launch for an ECS Cluster?

1. Specify instance type and amount of containers

2. Define networking, IAM policies, and CPU/memory

3. Patch and scale instances manually

4. Use only pre-defined images from AWS

The correct answer is: Define networking, IAM policies, and CPU/memory

When performing a Fargate launch for an Amazon ECS (Elastic Container Service) Cluster, defining networking, IAM policies, and CPU/memory is essential. Fargate provides a serverless compute engine, allowing you to run containers without managing the underlying infrastructure. By specifying networking configurations, you can determine how your tasks communicate with each other and with other services. This includes selecting the virtual network, subnets, and security groups that govern the traffic flow and access rights for your containerized applications. IAM policies are vital for ensuring that your tasks have the necessary permissions to access other AWS services securely. By defining the appropriate IAM roles and policies, you can enforce security best practices and limit the scope of permissions granted to your Fargate tasks. Specifying CPU and memory requirements is crucial because it directly impacts the performance of your containers. Fargate requires you to define the resources allocated to each task, allowing optimal scaling and resource use within your application. The other options do not encapsulate the requirements for Fargate launches correctly. For instance, specifying an instance type and the number of containers is not required in Fargate since it abstracts away the infrastructure management aspect. Patching and scaling instances manually is also unnecessary, as Fargate
