Exam AZ-104 topic 4 question 110 discussion

Surprisingly C because 'If you don't specify a resource limit, the container instance's maximum resource usage is the same as its resource request.' https://learn.microsoft.com/en-us/azure/container-instances/container-instances-container-groups Hence none will go above their initial resource request. Actually makes sense that not specifying it wouldn't let it just be unlimited or something as was my initial thought.

If you don't specify a resource limit, the container instance's maximum resource usage is the same as its resource request.

Exactly, you've got it right! Azure Container Instances (ACI) are charged based on the allocated resources, such as CPU and memory, which means they do not support automatic scaling of CPU resources. On the other hand, Azure Container Apps (ACA) can automatically scale CPU resources because they operate on a pay-as-you-go model. So, to ensure that container2 doesn't use the CPU allocated to container1, you need to decrease the resource limit of container2 to 2 CPUs, matching its resource request. This way, container2 will not exceed its allocated resources and will not impact container1's performance.

Correct is C

If you don't specify a resource limit, the container instance's maximum resource usage is the same as its resource request https://learn.microsoft.com/en-us/azure/container-instances/container-instances-container-groups

Its D not C. Why ? see below Unpredictable Performance: Without defined limits, the performance of each container becomes unpredictable. Under heavy load, one container might starve the other of resources, leading to instability and degraded performance for both. This is not what we want to achieve in the question. Fair Resource Allocation: Setting resource limits ensures that each container gets a fair share of resources. This is particularly important in environments where resource usage needs to be predictable and stable.

it´s C

chatGPT D. Decrease the resource limit of container2 to two CPUs. Here’s why: In this scenario, container2 has a resource request of 3 CPUs and a resource limit of 4 CPUs, while container1 has both a request and a limit of 2 CPUs. Since container2 has a higher resource request (3 CPUs) than container1 (2 CPUs), it could potentially starve container1 of the CPU resources it needs, especially if the CPU load increases. By decreasing the resource limit of container2 to 2 CPUs, you ensure that both containers have equal access to CPU resources (i.e., 2 CPUs each), preventing container2 from consuming more resources than necessary and negatively impacting container1.

C should be the right answer

I think the Answer is C. The resources allocated to Group1 is 5 CPUs Option D must be wrong. It is because the resource limit of a container instance must be greater than or equal to the mandatory resource request property. The resource limit of container 2 must be 3 or greater. Option B is wrong as well. The maximum resource limit you can set for a container instance is the total resources allocated to the group. Thus, maximum request limit of container2 is 5. Also, Resource limit of container2 is 4. Container2 could use up to 4 CPUs that will negatively impact container1. Increase it 6 CPUs will make the situation even worse. Option A can not stop container2 use up to 4 CPUs.
