AZ-104 Certification Practice Question #202

Question

You have an Azure subscription that contains a container group named Group1. Group1 contains two Azure container instances as shown in the following table.

You need to ensure that container2 can use CPU resources without negatively affecting container1.

What should you do?

Accepted Answer

In Azure Container Instances (ACI), a container group's resources are allocated based on the sum of the resource requests of its container instances (2 CPUs + 3 CPUs = 5 CPUs total). If you define a resource limit for a container that is higher than its request (for container2, request is 3 CPUs and limit is 4 CPUs), that container can burst up to the limit if resources are available, which can decrease the resource availability for other containers (starving container1 of its requested 2 CPUs). By removing the resource limits for both containers (Option C), each container's resource limit will default to its resource request. This caps container2's maximum CPU usage at exactly 3 CPUs, ensuring that container1's requested 2 CPUs remain fully available and unaffected. Note that option D is invalid because in ACI, a container's resource limit must be greater than or equal to its resource request (and container2 requests 3 CPUs).
