  With the public cloud, you get pay-as-you-go pricing ?you pay only for what you use, no CapEx costs. With the public cloud, you have self-service management. You are responsible for the deployment and configuration of the cloud resources such as virtual machines or web sites. The underlying hardware that hosts the cloud resources is managed by the cloud provider.

  Incorrect Answers:

  A: You don't have dedicated hardware. The underlying hardware is shared so you could have multiple customers using cloud resources hosted on the same physical hardware.

  B: Connections to the public cloud are secure.

  C: Storage is not limited. You can have as much storage as you like.

• Question 3:

  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.

• Question 4:

  You have an on-premises application that sends email notifications automatically based on a rule.

  You plan to migrate the application to Azure.

  You need to recommend a serverless computing solution for the application.

  What should you include in the recommendation?

  A. a web app
  B. a server image in Azure Marketplace
  C. a logic app
  D. an API app
  C. a logic app

  ---

  Azure Logic Apps is a cloud service that helps you schedule, automate, and orchestrate tasks, business processes, and workflows when you need to integrate apps, data, systems, and services across enterprises or organizations. Logic Apps simplifies how you design and build scalable solutions for app integration, data integration, system integration, enterprise application integration (EAI), and business-to-business (B2B) communication, whether in the cloud, on premises, or both. For example, here are just a few workloads you can automate with logic apps:

  1. Process and route orders across on-premises systems and cloud services.

  2. Send email notifications with Office 365 when events happen in various systems, apps, and services.

  3. Move uploaded files from an SFTP or FTP server to Azure Storage.

  4. Monitor tweets for a specific subject, analyze the sentiment, and create alerts or tasks for items that need review.

• Question 5:

  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:

  Availability zones expand the level of control you have to maintain the availability of the applications and data on your VMs. Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. To ensure resiliency, there are a minimum of three separate zones in all enabled regions. The physical separation of Availability Zones within a region protects applications and data from datacenter

  failures.

  With Availability Zones, Azure offers industry best 99.99% VM uptime SLA. By architecting your solutions to use replicated VMs in zones, you can protect your applications and data from the loss of a datacenter. If one zone is compromised, then replicated apps and data are instantly available in another zone.

  You can use availability zones in azure to protect azure virtual machines from a datacenter failure. Yes

  You can use availability zones in azure to protect azure virtual machines from a region failure. No

  You can use availability zones in azure to protect azure managed disks from a datacenter failure. Yes

• Question 6:

  Which Azure service can be used to synchronize on-premises directories with Azure AD?

  A. Azure Arc
  B. Azure AD Connect
  C. Azure Migrate
  D. Azure Backup
  B. Azure AD Connect

  ---

  Azure AD Connect synchronizes identities between on-premises AD and Azure AD.

• Question 7:

  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.

  You can assign additional account administrators in the Azure Portal.

  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.

• Question 8:

  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.

  You have an Azure environment.

  You need to create a new Azure virtual machine from a tablet that runs the Android operating system.

  Solution: You use the PowerApps portal.

  Does this meet the goal?

  A. Yes
  B. No
  B. No

  ---

  You have an Azure environment.

  You need to create a new Azure virtual machine (VM).

  You are doing this from a tablet running Android.

  Solution Provided: Use the PowerApps portal.

  Analysis:

  PowerApps is a low-code/no-code platform for building business applications (web + mobile), typically for forms, workflows, or apps that connect to data sources.

  PowerApps Portal allows external users to interact with apps/data via websites.

  PowerApps is NOT designed to provision or manage Azure infrastructure, such as creating virtual machines.

  Why the solution does NOT meet the goal:

  PowerApps Portal cannot create or manage Azure virtual machines.

  Therefore, using PowerApps Portal fails to meet the stated goal of creating a VM from an Android tablet.

  Correct alternatives:

  Azure Portal (web UI): Can create/manage VMs from any supported browser, including Android tablets.

  Azure mobile app: Supports monitoring and managing Azure resources, including creating VMs on Android tablets.

  Conclusion: Does the solution meet the goal? NO-Reason: PowerApps Portal is for building business apps, not for Azure infrastructure management.

• Question 9:

  HOTSPOT

  Select the answer that correctly completes the sentence.

  

  

  Explanation:

  Azure policies provide a common platform for deploying objects to a cloud infrastructure and for implementing consistency across the azure environment.

• Question 10:

  You have an Azure environment that contains multiple Azure virtual machines.

  You plan to implement a solution that enables the client computers on your on-premises network to communicate to the Azure virtual machines.

  You need to recommend which Azure resources must be created for the planned solution.

  Which two Azure resources should you include in the recommendation? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. a virtual network gateway
  B. a load balancer
  C. an application gateway
  D. a virtual network
  E. a gateway subnet
  A. a virtual network gateway
  E. a gateway subnet

  ---

  Why These Answers Are Correct:

  1. Virtual Network Gateway

  A virtual network gateway is required to provide VPN or ExpressRoute connectivity between on-premises networks and Azure virtual networks.

  It enables secure communication between client computers on-premises and Azure virtual machines.

  2. Gateway Subnet-A gateway subnet is a dedicated subnet within an Azure virtual network that contains the IP addresses used by the virtual network gateway.-It is required for the virtual network gateway to function.

  https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-about-vpngateways

  "To create a VPN gateway, you must create a virtual network gateway in a dedicated gateway subnet within the virtual network."

  Why the Other Options Are Incorrect:

  Load Balancer-Incorrect.-Load balancers distribute traffic among multiple VMs but do not provide connectivity between on-premises networks and Azure.

  Application Gateway-Incorrect.-Application Gateway is an application-level (Layer 7) load balancer for HTTP/HTTPS traffic, not for VPN connectivity.

  Virtual Network-Incorrect.-A virtual network is required but is assumed to already exist; it is not sufficient alone for on-premises connectivity without a gateway and gateway subnet.
