Microsoft AZ-900 Online Questions & Answers

• Question 201:

  HOTSPOT

  To complete the sentence, select the appropriate option in the answer area.

  

  

  Explanation:

  When planning to migrate a public website to Azure, you must plan to pay monthly usage costs. This is because Azure uses the pay-as-you-go model.

• Question 202:

  Which Azure service can you use as a security information and event management (SIEM) solution?

  A. Azure Analysis Services
  B. Azure Sentinel
  C. Azure Information Protection
  D. Azure Cognitive Services
  B. Azure Sentinel

  ---

  Microsoft Sentinel (formerly Azure Sentinel) is the cloud-native SIEM and unified security platform from Microsoft.

  It collects security data and logs from across your environment (cloud, on-premises, multi-cloud), then uses analytics, threat intelligence, and automation to detect, investigate, and respond to security incidents. :contentReference[oaicite:1]{index=1}

  Azure Sentinel provides capabilities like threat detection, alerting, incident investigation, and automated response - all core SIEM functions. :contentReference[oaicite:2]{index=2}

  Incorrect Options:

  Azure Analysis Services: A data-analysis and OLAP service - not used for security event management.

  Azure Information Protection: Focuses on classification and protection of documents/data - not SIEM.

  Azure Cognitive Services: A set of AI/ML APIs - not related to log collection or security event aggregation.

• Question 203:

  HOTSPOT

  The cool access tier is optimized ________________________

  Select the answer that correctly completes the sentence.

  

  

  Explanation:

  Box: for data that is accessed infrequently and stored for at least 30 days

  Cool tier - An online tier optimized for storing data that is infrequently accessed or modified. Data in the cool tier should be stored for a minimum of 30 days. The cool tier has lower storage costs and higher access costs compared to the hot tier.

  Incorrect:

  * for data that is accessed rarely, is stored for at least 180 days, ..

• Question 204:

  You plan to deploy an application that must automatically scale based on CPU usage and HTTP request count. You need to use a PaaS solution that supports autoscaling without managing virtual machines. What should you use?

  A. Azure Virtual Machines
  B. Azure App Service
  C. Azure Functions with Consumption plan
  D. Azure Kubernetes Service (AKS)
  B. Azure App Service

  ---

  Azure App Service provides built-in autoscaling based on metrics such as CPU, memory, and request count. Virtual Machines require manual scaling configuration. AKS offers scaling but requires cluster management. Azure Functions scale automatically but are event-driven, not ideal for full web applications.

• Question 205:

  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

  an azure subscription can be associated to multiple azure active directory tenants.

  An Azure AD tenant can have multiple subscriptions but an Azure subscription can only be associated with one Azure AD tenant.

  Box 2: Yes

  Box 3: No

  If your subscription expires, you lose access to all the other resources associated with the subscription. However, the Azure AD directory remains in Azure. You can associate and manage the directory using a different Azure subscription.

• Question 206:

  You have an on-premises network that contains several servers.

  You plan to migrate all the servers to Azure.

  You need to recommend a solution to ensure that some of the servers are available if a single Azure data center goes offline for an extended period.

  What should you include in the recommendation?

  A. fault tolerance
  B. elasticity
  C. scalability
  D. low latency
  A. fault tolerance

  ---

  Fault tolerance is the ability of a system to continue to function in the event of a failure of some of its components. In this question, you could have servers that are replicated across datacenters.

  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.

• Question 207:

  HOTSPOT

  Select the answer that correctly completes the sentence.

  

  

  Explanation:

  Authentication is the process of verifying a user's credentials.

• Question 208:

  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 macOS and has PowerShell Core 6.0 installed.

  Does this meet the goal?

  A. Yes
  B. No
  B. No

  ---

  Although macOS is a valid operating system for running PowerShell, PowerShell Core 6.0 is an outdated and unsupported version for managing Azure resources.

  Microsoft no longer recommends or supports PowerShell 6.x for Azure automation. Certification exams test against current, supported, and recommended configurations—not legacy runtimes.

  Microsoft now recommends:

  -PowerShell 7.x for running Azure PowerShell locally, or

  -Azure Cloud Shell as a fully supported alternative.

  Because PowerShell Core 6.0 is end-of-life and unsupported, the solution is not valid on an official Microsoft exam.

  CORRECT APPROACH:

  Use one of the following supported solutions instead:

  -PowerShell 7.x (on Windows, macOS, or Linux)

  -Azure Cloud Shell

  CONCLUSION:

  Since the solution specifies an unsupported PowerShell version, selecting "Yes" would be incorrect.

  The correct exam answer is: NO

• Question 209:

  HOTSPOT

  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 can have two azure storage accounts that have the same name in the same azure subscription.

  Your storage account name must be unique within Azure. No two storage accounts can have the same name.

  Box 2: No

  Box 3: No

• Question 210:

  Which task can you perform by using Azure Advisor?

  A. Integrate Active Directory and Azure Active Directory (Azure AD).
  B. Estimate the costs of an Azure solution.
  C. Confirm that Azure subscription security follows best practices.
  D. Evaluate which on-premises resources can be migrated to Azure.
  C. Confirm that Azure subscription security follows best practices.

  ---

  Azure Advisor analyzes your Azure resources and provides best-practice recommendations in these areas: high availability, security, performance, and cost.

  Security recommendations help ensure that your subscription and resources follow Azure security best practices.

  Incorrect Options:

  Integrate Active Directory and Azure Active Directory (Azure AD):

  Requires Azure AD Connect or other identity tools, not Azure Advisor.

  Estimate the costs of an Azure solution:

  Done via Azure Pricing Calculator or Azure Cost Management, not Azure Advisor.

  Evaluate which on-premises resources can be migrated to Azure: Performed using Azure Migrate, not Azure Advisor.
