Microsoft AZ-900 Online Questions & Answers

• Question 321:

  Which Service Level Agreement (SLA) is provided for Azure services in public preview?

  A. Each service defines its own SLA.
  B. The SLA will be 99%.
  C. The SLA will be 1% less than the general availability (GA) SLA.
  D. The SLA will be 99.95%.
  A. Each service defines its own SLA.

  ---

  Azure services in public preview generally DO NOT come with a standard SLA.

  Microsoft does not guarantee availability or performance for preview services unless the service documentation explicitly states otherwise. In most cases, preview services

  are offered without any SLA, and if an SLA exists, it is defined by that specific service.

  Reasons the other options are incorrect:

  The SLA will be 99%:

  There is no default SLA percentage for preview services.

  Microsoft does not guarantee availability during preview.

  The SLA will be 1% less than the general availability (GA) SLA:

  Microsoft does not base preview SLAs on GA SLAs.

  There is no such policy stated in Microsoft documentation.

  The SLA will be 99.95%:

  This value applies to some GA services only.

  Preview services do not automatically receive an SLA.

• Question 322:

  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

  You must have internet connectivity to manage cloud services.

  Box 2: No

  Cloud services can be managed through

  https://portal.azure.com/

  In the Cloud Services area of the Azure portal, you can:

  Update a service role or a deployment.

  Promote a staged deployment to production.

  Link resources to your cloud service so that you can see the resource dependencies and scale the resources together.

  Delete a cloud service or a deployment.

  Box 3: Yes

• Question 323:

  What is an example of vertical scaling in a cloud environment?

  A. adding an additional CPU to an existing Azure virtual machine
  B. adding an additional Azure virtual machine
  C. adding an additional Azure Virtual Desktop session host
  D. adding an additional Azure App Service instance automatically
  A. adding an additional CPU to an existing Azure virtual machine

  ---

  Scaling up and down, which is also referred to as vertical scaling, is the process of upgrading an existing virtual machine to a more powerful virtual machine, or downgrading to a smaller, less powerful virtual machine. In Azure, this means resizing the existing VM to a larger size with more RAM and more CPU, or to a smaller size with less RAM and less CPU. Because vertical scaling involves the re-size of virtual machines, this kind of scaling results in VM restarts.

• Question 324:

  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

  If your company uses an azure free account, you can only deploy azure virtual machines and azure storage accounts..

  Azure Free Account gives you 12 months access to the most popular free services. It also gives you a credit (150 GBP or 200 USD) to use on any Azure service for up to 30 days.

  Box 2: Yes

  All free accounts expire after 12 months.

  Box 3: No

  You can only create one free Azure account per Microsoft account.

• Question 325:

  You need to migrate an on-premises server by using a lift-and-shift migration.

  To which type of cloud service should you migrate?

  A. infrastructure as a service (IaaS)
  B. software as a service (SaaS)
  C. platform as a service (PaaS)
  A. infrastructure as a service (IaaS)

  ---

  Lift-and-shift migration involves moving an existing on-premises workload to the cloud without changing its architecture. This typically means deploying the workload on virtual machines in the cloud, which corresponds to Infrastructure as a Service (IaaS).

  IaaS provides virtualized compute, storage, and networking, allowing you to replicate on-premises servers in Azure without modifying the applications.

  Reasons why other options are incorrect: Software as a Service (SaaS): SaaS provides fully managed applications (e.g., Office 365), which would require re-architecting your workload to use a SaaS solution-does not fit lift-and-shift.

  Platform as a Service (PaaS): PaaS abstracts the underlying infrastructure and requires adapting applications to the platform, which goes beyond a lift-and-shift approach.

• Question 327:

  You have a virtual machine named VM1 that runs Windows Server 2016. VM1 is in the East US Azure region.

  Which Azure service should you use from the Azure portal to view service failure notifications that can affect the availability of VM1?

  A. Azure Service Fabric
  B. Azure Monitor
  C. Azure virtual machines
  D. Azure Advisor
  B. Azure Monitor

  ---

  Azure Monitor includes the Azure Service Health feature, which provides personalized dashboards for viewing service failure notifications, planned maintenance, and health advisories that can affect the availability of resources like VM1.

  Azure Advisor provides best practice recommendations but does not provide real-time service failure notifications.

  Azure Service Fabric is for deploying and managing microservices, not for monitoring platform health.

  Azure virtual machines is a resource management blade, not a service for platform failure notifications.

  "Azure Service Health provides personalized alerts and guidance when Azure service issues like outages or maintenance affect your resources."-Microsoft Learn:

  "Azure Monitor collects, analyzes, and acts on telemetry from your cloud and on-premises environments. It integrates Azure Service Health to notify you of platform incidents and planned maintenance."

• Question 328:

  Explanation:

• Question 329:

  Your company plans to deploy several custom applications to Azure.

  The applications will provide invoicing services to the customers of the company.

  Each application will have several prerequisite applications and services installed.

  You need to recommend a cloud deployment solution for all the applications.

  What should you recommend?

  A. Software as a Service (SaaS)
  B. Platform as a Service (PaaS)
  C. Infrastructure as a Service (laaS)
  C. Infrastructure as a Service (laaS)

  ---

  Infrastructure as a service (IaaS) is an instant computing infrastructure, provisioned and managed over the internet. The IaaS service provider manages the infrastructure, while you purchase, install, configure, and manage your own software

  Incorrect Answers:

  A: Software as a service (SaaS) allows users to connect to and use cloud-based apps over the Internet. Common examples are email, calendaring, and office tools. In this scenario, you need to run your own apps, and therefore require an infrastructure.

  B:Platform as a service (PaaS) is a complete development and deployment environment in the cloud. PaaS includes infrastructure--servers, storage, and networking--but also middleware, development tools, business intelligence (BI) services, database management systems, and more. PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing, and updating.
