You have an Azure subscription that contains the resources shown in the following table.



You need to configure a proximity placement group for VMSS1.
Which proximity placement groups should you use?

  1. Proximity2 only
  2. Proximity1, Proximity2, and Proximity3
  3. Proximity1 only
  4. Proximity1 and Proximity3 only

Answer(s): C

Explanation:

Resource Group location of VMSS1 is the RG2 location, which is West US.
Only Proximity1, which also in RG2, is located in West US.

Note: When you assign your virtual machines to a proximity placement group, the virtual machines are placed in the same data center, resulting in lower and deterministic latency for your applications.

HOTSPOT (Drag and Drop is not supported)
You are creating an Azure Kubernetes Services (AKS) cluster as shown in the following exhibit.




Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic.

NOTE: Each correct selection is worth one point.

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Box 1: modify the Network configuration setting
From the exhibit we see; Network policy: None

To run an AKS cluster that supports node pools for Windows Server containers, your cluster needs to use a network policy that uses Azure CNI (advanced) network plugin.

Incorrect:
* enable virtual nodes
To rapidly scale application workloads in an AKS cluster, you can use virtual nodes. With virtual nodes, you have quick provisioning of pods, and only pay per second for their execution time. You don't need to wait for Kubernetes cluster autoscaler to deploy VM compute nodes to run the additional pods. Virtual nodes are only supported with Linux pods and nodes.

* increase the number of node pools
The following additional limitations apply to Windows Server node pools:
The AKS cluster can have a maximum of 10 node pools.
The AKS cluster can have a maximum of 100 nodes in each node pool.
The Windows Server node pool name has a limit of 6 characters.

Box 2: AKS-managed Azure Active Directory
When you're using Azure Container Registry (ACR) with Azure Kubernetes Service (AKS), an authentication mechanism needs to be established.

Create a new AKS cluster with ACR integration
You can set up AKS and ACR integration during the initial creation of your AKS cluster. To allow an AKS cluster to interact with ACR, an Azure Active Directory managed identity is used.

Incorrect:
* Authentication method

HOTSPOT (Drag and Drop is not supported)
You have an Azure subscription that contains an Azure Kubernetes Service (AKS) cluster named Cluster1. Cluster1 hosts a node pool named Pool1 that has four nodes.

You need to perform a coordinated upgrade of Cluster1. The solution must meet the following requirements:

-Deploy two new nodes to perform the upgrade.
-Minimize costs.

How should you complete the command? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Box 1: add
az aks nodepool add
Add a node pool to the managed Kubernetes cluster.

Box 2: --max-surge 2
Extra nodes used to speed upgrade. When specified, it represents the number or percent used, eg. 5 or 33%.

Incorrect:
* --max-count 2
Maximum nodes count used for autoscaler, when "--enable-cluster-autoscaler" specified. Please specify the value in the range of [0, 1000] for user nodepool, and [1,1000] for system nodepool.

However, autoscaler not mention in the question.

* --max-pods -m
The maximum number of pods deployable to a node.

* --node-count -c
Number of nodes in the Kubernetes agent pool. After creating a cluster, you can change the size of its node pool with az aks scale.

default value: 3


Reference:

HOTSPOT (Drag and Drop is not supported)
You have an Azure subscription.

You create the following file named Deploy.json.




You connect to the subscription and run the following commands.



For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Box 1: Yes

The New-AzResourceGroup cmdlet creates an Azure resource group.
The New-AzResourceGroupDeployment cmdlet will create 3 resources as count is set to 3.

Using copy
To create multiple instances of a resource with a nested template, add the copy element at the level of the Microsoft.Resources/deployments resource. Or, if the scope is inner, you can add the copy within the nested template.

Note: The New-AzResourceGroupDeployment cmdlet adds a deployment to an existing resource group. This includes the resources that the deployment requires. An Azure resource is a user-managed Azure entity, such as a database server, database, website, virtual machine, or Storage account. An Azure resource group is a collection of Azure resources that are deployed as a unit, such as the website, database server, and databases that are required for a financial website. A resource group deployment uses a template to add resources to a resource group and publishes them so that they are available in Azure.

Box 2: No
In the template the defaultValue of Location is westus, but the account created by the New-AzResourceGroup command has location set to CentralRus.

Box 3: Yes
The Storage Accounts will be created with template.
The name of each resource includes the copyIndex() function, which returns the current iteration in the loop. copyIndex() is zero-based.

So, the following example:

"name": "[concat('storage', copyIndex())]",

Creates these names:

storage0
storage1
storage2
