• Question 331:

  You need to manage containers.

  Which two services can you use? Each correct answer presents a complete solution,

  NOTE: Each correct selection is worth one point.

  A. Azure Virtual Desktop
  B. Azure virtual machines
  C. Azure Functions
  D. Azure Kubernetes Service (AKS)
  E. Azure Container Instances
  D. Azure Kubernetes Service (AKS)
  E. Azure Container Instances

  ---

  Run Docker containers on-demand in a managed, serverless Azure environment. Azure Container Instances is a solution for any scenario that can operate in isolated containers, without orchestration. Run event-driven applications, quickly deploy from your container development pipelines, and run data processing and build jobs.

  You can manage containers at scale with a fully managed Kubernetes container management and orchestration service that integrates with Azure Active

  Directory.

  Azure Kubernetes Service is a robust and cost-effective container orchestration service that helps you to deploy and manage containerized applications in seconds where additional resources are assigned automatically without the headache of managing additional servers.

• Question 332:

  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

  Azure resources can only access other resources in the same resource group.

  A resource can interact with resources in other resource groups.

  Box 2: Yes

  Deleting the resource group will remove the resource group as well as all the resources in that resource group. This can be useful for the management of resources. For example, a virtual machine has several components (the VM itself, virtual disks, network adapter etc.). By placing the VM in its own resource group, you can delete the VM along with all its associated components by deleting the resource group.

  Another example is when creating a test environment. You could place the entire test environment (Network components, virtual machines etc.) in one resource group. You can then delete the entire test environment by deleting the resource group.

  Box 3: Yes

  Resources from multiple different regions can be placed in a resource group. The resource group only contains metadata about the resources it contains.

• Question 333:

  Your company plans 10 migrate all its data and resources to Azure.

  The company's migration plan states that only Platform as a Service (PaaS) solutions must be used in Azure

  You need to deploy an Azure environment that meets the company's migration plan

  What should you create?

  A. an Azure App Service and Azure SQL databases
  B. Azure storage accounts and web server in Azure virtual machines
  C. Azure virtual machines. Azure SQL databases, and Azure Storage accounts
  D. an Azure App Service and Azure virtual machines that have Microsoft SQL Server installed
  A. an Azure App Service and Azure SQL databases

  ---

  Azure App Service and Azure SQL databases are examples of Azure PaaS solutions. Therefore, this solution does meet the goal.

  **Azure App Service** is a PaaS offering for hosting web apps without managing the VM or OS.

  **Azure SQL Database** is a fully managed PaaS database service.

  This combination satisfies the requirement to use only PaaS solutions.

  Incorrect Options:

  1.

  Azure storage accounts and web server in Azure virtual machines: Using a VM for the web server is **IaaS**, not PaaS.

  2.

  Azure virtual machines, Azure SQL databases, and Azure Storage accounts: Virtual machines are **IaaS**, violating the migration plan requirement.

  3.

  Azure App Service and Azure virtual machines with SQL Server installed: Using a VM for SQL Server is **IaaS**, which is not allowed per the plan.

• Question 334:

  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

  To implement an azure multi-factor authentication (MTA) solution, you must deploy a federation solution or sync on-premises identities to the cloud.

  It is not true that you must deploy a federation solution or sync on-premises identities to the cloud. You can have a cloud-only environment and use MFA.

  Box 2: No

  Picture identification and passport numbers are not valid MFA authentication methods. Valid methods include: Password, Microsoft Authenticator App, SMS and Voice call.

  Box 3:

  You can configure MFA to be required for administrator accounts only or you can configure MFA for any user account.

• Question 335:

  Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

  After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

  An Azure administrator plans to run a PowerShell script that creates Azure resources.

  You need to recommend which computer configuration to use to run the script.

  Solution: Run the script from a computer that runs Linux and has the Azure CLI tools installed.

  Does this meet the goal?

  A. Yes
  B. No
  B. No

  ---

  PowerShell scripts require the Azure PowerShell module or PowerShell Core installed to run.

  Installing only the Azure CLI on Linux does not allow execution of PowerShell scripts.-To meet the goal, the administrator would need either:

  1. A machine with PowerShell installed (Windows or Linux with PowerShell Core), or

  2. Use Azure Cloud Shell, which comes with PowerShell pre-installed.

  References: Microsoft Learn:

  https://learn.microsoft.com/en-us/powershell/azure/install-az-ps

  "Azure PowerShell works on Windows, Linux, and macOS, but PowerShell must be installed before running scripts."-Microsoft Learn:

  https://learn.microsoft.com/en-us/cli/azure/install-azure-cli

  "The Azure CLI is a separate tool and cannot execute PowerShell scripts on its own."

• Question 336:

  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

  You must have physical servers to use cloud computing.

  A PaaS solution does not provide access to the operating system. The Azure Web Apps service provides an environment for you to host your web applications. Behind the scenes, the web apps are hosted on virtual machines running IIS. However, you have no direct access to the virtual machine, the operating system or IIS.

  Box 2: Yes

  A PaaS solution that hosts web apps in Azure does provide the ability to scale the platform automatically. This is known as autoscaling. Behind the scenes, the web apps are hosted on virtual machines running IIS. Autoscaling means adding more load balanced virtual machines to host the web apps.

  Box 3: Yes

  PaaS provides a framework that developers can build upon to develop or customize cloud-based applications. PaaS development tools can cut the time it takes to code new apps with pre-coded application components built into the platform, such as workflow, directory services, security features, search and so on.

• Question 337:

  HOTSPOT

  Select the answer that correctly completes the sentence.

  

  

  Explanation:

  Box: Platform as a service (PaaS)

  Platform as a service (PaaS) is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications. You purchase the resources you need from a cloud service provider on a pay- as-you-go basis and access them over a secure Internet connection.

  Like IaaS, PaaS includes infrastructure"servers, storage, and networkingג€andquot;but also middleware, development tools, business intelligence (BI) services, database management systems, and more.

  A microsoft sql sever database that is hosted in the cloud and has software updates managed by azure is an example of platform as a service.

• Question 338:

  You plan to deploy a service to Azure virtual machines.

  You need to ensure that the service will be available if a datacenter fails.

  What should you use as part of the virtual machine deployment?

  A. availability sets
  B. proximity placement groups
  C. host groups
  D. availability zones
  D. availability zones

  ---

  Azure availability zones are physically separate locations within each Azure region that are tolerant to local failures. Failures can range from software and hardware failures to events such as earthquakes, floods, and fires. Tolerance to failures is achieved because of redundancy and logical isolation of Azure services. To ensure resiliency, a minimum of three separate availability zones are present in all availability zone-enabled regions.

• Question 339:

  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

  Each azure subscription can contain multiple account administrators.

  An Azure subscription can have multiple administrators, including Service Administrators, Co-Administrators, and Azure AD administrators.

  Box 2: No

  You need an Azure Active Directory account to manage a subscription, not a Microsoft account.

  An account is created in the Azure Active Directory when you create the subscription. Further accounts can be created in the Azure Active Directory to manage the subscription.

  Box 3: No

  Resource groups are logical containers for Azure resources. However, resource groups do not contain subscriptions. Subscriptions contain resource groups.

  Reference:

• Question 340:

  You need to be notified when Microsoft plans to perform maintenance that can affect the resources deployed to an Azure subscription. What should you use?

  A. Azure Monitor
  B. Azure Service Health
  C. Azure Advisor
  D. Microsoft Trust Center
  B. Azure Service Health

  ---

  Azure Service Health provides a personalized view of the health of the Azure services and regions you're using. This is the best place to look for service impacting communications about outages, planned maintenance activities, and other health advisories because the authenticated Service Health experience knows which services and resources you currently use.
