Exam AZ-104 topic 4 question 41 discussion

Correct Answer: B and D We need to configure autoscaler for the AKS cluster. We do not want to scale Kubernetes pods, so kubectl command is not needed. A: kubectl command is used for configuring Kubernetes and not AKS cluster. B: The az aks command is used for the AKS cluster configuration. C: Set-AzVm cmdlet is used for VMs. D: Azure portal, under node pools, press scale, then choose auto scale. E: Set-AzAks, creates or updates an AKS cluster, the correct cmdlet is Set-AzAksCluster. AKS clusters can scale in one of two ways: - The cluster autoscaler watches for pods that can't be scheduled on nodes because of resource constraints. The cluster then automatically increases the number of nodes. - The horizontal pod autoscaler uses the Metrics Server in a Kubernetes cluster to monitor the resource demand of pods. If an application needs more resources, the number of pods is automatically increased to meet the demand. Reference: https://docs.microsoft.com/en-us/azure/aks/cluster-autoscaler

The Answer is not correct. The right is B & D. B is for az aks command , check https://docs.microsoft.com/en-us/azure/aks/cluster-autoscaler D is for Azure portal. Under node pools, press scale, then choose auto scale. The Answer A is not correct as it is confusing with Horizontal pod autoscale which is not asked here. The pod autoscale use kubectl.

To configure the cluster autoscaler for an Azure Kubernetes Service (AKS) cluster, you can use the following tools: 1. **A. the kubectl command** - You can use `kubectl` to apply configurations related to the autoscaler, such as deploying the autoscaler deployment in your AKS cluster. 2. **B. the az aks command** - The Azure CLI (`az aks`) provides commands to enable and configure the cluster autoscaler directly on your AKS cluster. ### Therefore, the correct answers are: - **A. the kubectl command** - **B. the az aks command**

B & D are correct

B + D are correct, you can use either one. https://learn.microsoft.com/en-us/azure/aks/cluster-autoscaler?tabs=azure-cli the target is to scale up/down the number of nodes. It has nothing to do with Kubernetes Pod Autoscalers (could be configured with A). You won't touch the ScaleSets themselve (C) and I'm not sure if Set-AzAks even exists (E)

A and B is correct

The Answer is not correct. The right is B & D. B is for az aks command , check https://docs.microsoft.com/en-us/azure/aks/cluster-autoscaler D is for Azure portal. Under node pools, press scale, then choose auto scale.

A. the kubectl command: kubectl is a command-line tool used for interacting with Kubernetes clusters, including managing deployments and pods within a cluster. However, it is not used to configure cluster-level settings like autoscaling. C. the Set-AzVm cmdlet: Set-AzVm is a PowerShell cmdlet used to manage Azure virtual machines (VMs), not AKS clusters or their autoscaling configurations. E. the Set-AzAks cmdlet: While the Set-AzAks cmdlet is used for managing AKS clusters in PowerShell, it is not specifically used for configuring cluster autoscaler. Cluster autoscaler configuration typically involves different commands or settings, and it's not part of the core Set-AzAks functionality. To configure cluster autoscaler for AKS, you primarily use the Azure CLI (az) or the Azure portal, as these tools are specifically designed for managing AKS cluster-level settings and configurations.

A and B are the right answer for this . https://learn.microsoft.com/en-us/azure/aks/cluster-autoscaler

Correct : AB The cluster autoscaler is a Kubernetes component. Although the AKS cluster uses a virtual machine scale set for the nodes, don't manually enable or edit settings for scale set autoscale in the Azure portal or using the Azure CLI. Let the Kubernetes cluster autoscaler manage the required scale settings. https://learn.microsoft.com/en-us/azure/aks/cluster-autoscaler

.Open AI: To configure cluster autoscaler for an Azure Kubernetes Service (AKS) cluster (AKS1), you can use the following tools: B. the az aks command: You can use the Azure Command-Line Interface (CLI) command az aks update to configure the cluster autoscaler for an AKS cluster. This command allows you to enable or disable the cluster autoscaler and set parameters like minimum and maximum node counts. D. the Azure portal: You can also configure the cluster autoscaler for AKS using the Azure portal. Navigate to your AKS cluster in the Azure portal, go to the "Node pools" section, and then configure the autoscaler settings for the specific node pool. The other options (A, C, and E) are not the primary tools used to configure cluster autoscaler for AKS.

Answer:AB Explanation: A: The following example uses the kubectl autoscale command to autoscale the number of pods in the azure-vote-front deployment. If average CPU utilization across all pods exceeds 50% of their requested usage, the autoscaler increases the pods up to a maximum of 10 instances. Aminimum of 3 instances is then defined for the deployment:kubectl autoscale deployment azure-vote-front --cpu-percent=50 --min=3 --max=10 B: Use the az aks update command to enable and configure the cluster autoscaler on the nodepool for the existing cluster.

BD is correct!

Answer: A and B Autoscale pods using kubectl autoscale example: kubectl autoscale deployment azure-vote-front --cpu-percent=50 --min=3 --max=10 https://learn.microsoft.com/en-us/azure/aks/tutorial-kubernetes-scale?tabs=azure-cli

A. the kubectl command B. the az aks command Explanation: The kubectl command is a command-line tool used to interact with Kubernetes clusters. It allows you to manage and configure various aspects of your AKS cluster, including enabling the cluster autoscaler. You can use kubectl to apply the necessary configuration changes to enable the autoscaler. The az aks command is a command-line tool provided by the Azure CLI (Command-Line Interface). It specifically deals with managing Azure Kubernetes Service (AKS) resources. Using the az aks command, you can enable the cluster autoscaler by modifying the AKS cluster's properties.
