AZ-104 · Question #746
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…
The correct answer is C. Remove the resource limit for both containers. To allow container2 to use CPU resources without negatively affecting container1, removing resource limits for both containers can help if container1 has a guaranteed CPU request.
Question

Why each option
To allow container2 to use CPU resources without negatively affecting container1, removing resource limits for both containers can help if container1 has a guaranteed CPU request.
Increasing container1's resource limit only allows container1 to consume more if it needs to, potentially reducing the pool of resources available for container2 without directly enabling container2 to burst.
Increasing container2's resource limit allows it to use more, but it doesn't prevent contention or guarantee container1's performance if container1's resources are not sufficiently protected by a request.
In Azure Container Instances, if a container has a CPU request defined, those resources are guaranteed. By removing the resource limit for both containers, container2 can then burst and utilize any available CPU resources in the container group that are not explicitly requested by container1, without causing throttling or impacting container1's guaranteed allocation.
Decreasing container2's resource limit would restrict its CPU usage, directly contradicting the goal of allowing container2 to use CPU resources.
