Microsoft AZ-900 Online Questions & Answers

• Question 81:

  HOTSPOT

  For each of the following statements, select Yes if the statement is true. Otherwise, select No.

  NOTE: Each correct selection is worth one point.

  

  

  Explanation:

  Box 1: Yes

  Azure arc can manage physical servers that run linux.

  Azure Arc-enabled servers let you manage Windows and Linux physical servers and virtual machines hosted outside of Azure, on your corporate network, or other cloud provider. For the purposes of Azure Arc, these machines hosted outside of Azure are considered hybrid machines. The management of hybrid machines in Azure Arc is designed to be consistent with how you manage native Azure virtual machines, using standard Azure constructs such as Azure Policy and applying tags.

  Box 2: Yes

  Azure Arc-enabled Kubernetes allows you to attach Kubernetes clusters running anywhere so that you can manage and configure them in Azure.

  Box 3: No

  Currently, Azure Arc allows you to manage the following resource types hosted outside of Azure:

  Servers: Manage Windows and Linux physical servers and virtual machines hosted outside of Azure.

  Kubernetes clusters: Attach and configure Kubernetes clusters running anywhere, with multiple supported distributions.

  Azure data services: Run Azure data services on-premises, at the edge, and in public clouds using Kubernetes and the infrastructure of your choice. SQL Managed Instance and PostgreSQL (preview) services are currently available.

  SQL Server: Extend Azure services to SQL Server instances hosted outside of Azure.

  Virtual machines (preview): Provision, resize, delete and manage virtual machines based on VMware vSphere or Azure Stack HCI and enable VM self-service through role-based access.

• Question 82:

  This question requires that you evaluate the underlined BOLD text to determine if it is correct.

  Azure Site Recovery provides fault tolerance for virtual machines.

  Instructions: Review the underlined text. If it makes the statement correct, select "No change is needed." If the statement is incorrect, select the answer choice that makes the statement correct.

  A. No change is needed.
  B. disaster recovery
  C. elasticity
  D. high availability
  B. disaster recovery

  ---

  Rationale / Sources:

  According to Microsoft, Site Recovery is used to replicate VMs and orchestrate failover in case of an outage, to ensure business continuity - i.e., disaster recovery, not immediate fault tolerance.

  The Azure Site Recovery FAQ explicitly calls it a disaster recovery service.

  Fault tolerance is defined more broadly as the ability for a system to continue operating through a failure, often via redundant systems.

  Microsoft's own AZ-900 exam guidance identifies “disaster recovery” (not fault tolerance) as the correct purpose of Site Recovery.

  Conclusion:

  Change the underlined text - it should read “disaster recovery” instead of “fault tolerance.”

• Question 83:

  HOTSPOT

  For each of the following statements, select Yes if the statement is true. Otherwise, select No.

  NOTE: Each correct selection is worth one point.

  

  

  Explanation:

  Box 1: No

  Adding more ram to a virtual machine is an example of horizontal scaling. No

  Horizontal scaling refers to adding more instances, or removing instances, of resources used by a workload. For example, extending an application from one compute instance to five compute instances. The Microsoft Azure cloud supports automatic horizontal scaling for compute instances, called virtual machines (VMs).

  Horizontal scaling is flexible in a cloud situation because you can use it to run a large number of VMs to handle load. In contrast, scaling up and down, or vertical scaling, keeps the same number of resource instances constant but gives them more capacity in terms of memory, CPU speed, disk space, and network.

  Box 2: No

  Box 3: Yes

  Autoscale scales in and out, or horizontally. Scaling horizontally is an increase or decrease of the number of resource instances.

• Question 84:

  Your company plans to deploy an Artificial Intelligence (AI) solution in Azure.

  What should the company use to build, test, and deploy predictive analytics solutions?

  A. Azure Logic Apps
  B. Azure Machine Learning Studio
  C. Azure Batch
  D. Azure Cosmos DB
  B. Azure Machine Learning Studio

  ---

  Azure Machine Learning Studi.

  Azure Machine Learning Studio is a cloud-based integrated development environment for building, training, and deploying machine learning models.-It supports predictive analytics and AI workflows.-Provides tools for data preparation, experimentation, model training, and deployment.

  Microsoft Learn Reference:

  https://learn.microsoft.com/en-us/azure/machine-learning/overview-what-is-azure-ml

  "Azure Machine Learning is a cloud-based environment you can use to train, deploy, automate, manage, and track ML models."

  Why the Other Options Are Incorrect:

  Azure Logic Apps-Incorrect.-Logic Apps is a workflow automation service for integrating apps, data, and services. It is not designed for building or deploying predictive analytics models.

  Azure Batch-Incorrect.-Azure Batch is used to run large-scale parallel and high-performance computing (HPC) workloads, not for AI model development.

  Azure Cosmos DB-Incorrect.-Cosmos DB is a globally distributed, multi-model database service and does not provide tools for building AI or predictive analytics models.

• Question 85:

  HOTSPOT

  For each of the following statements, select Yes if the statement is true. Otherwise, select No.

  NOTE: Each correct selection is worth one point.

  

  

  Explanation:

  You can add an azure resource manager template to an azure blueprint. Yes

  Reference:

• Question 86:

  Your company has several business units.

  Each business unit requires 20 different Azure resources for daily operation. All the business units require the same type of Azure resources.

  You need to recommend a solution to automate the creation of the Azure resources.

  What should you include in the recommendations?

  A. Azure Resource Manager templates
  B. virtual machine scale sets
  C. the Azure API Management service
  D. management groups
  A. Azure Resource Manager templates

  ---

  You can use Azure Resource Manager templates to automate the creation of the Azure resources. Deploying resource through templates is known as `Infrastructure as code'.

  To implement infrastructure as code for your Azure solutions, use Azure Resource Manager templates. The template is a JavaScript Object Notation (JSON) file that defines the infrastructure and configuration for your project. The template uses declarative syntax, which lets you state what you intend to deploy without having to write the sequence of programming commands to create it. In the template, you specify the resources to deploy and the properties for those resources.

  To answer, drag the appropriate storage service from the column on the left to its description on the right. Each service may be used once, more than once, or not at all.

  Select and Place:

  

  

  Explanation:

  Box 1: Azure Queue Storage

  Queue Storage

  Durable queues for large-volume cloud services

  Simple, cost-effective, durable message queueing for large workloads

  Rich client libraries for .NET, Java, Android, C++, Node.js, PHP, Ruby, and Python

  Data accessible via the REST API

  Box 2: Azure Files

  You can map a Network File Share to an Azure Windows VM.

  Box 3: Azure Blob Storage

  Azure Archive Storage is yet another storage tier available for blob storage. Hot, cool, and archive objects can all exist side by side in the same account. And with the introduction of blob-level tiering, you can change an object's tier with a single click in the Azure portal, or you can use the REST API (or .NET, Java, Python, and a number of other SDKs) to programmatically change as many objects as needed.
