• Question 131:

  HOTSPOT

  Which cloud deployment is used for Azure virtual machines and Azure SQL database? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  

  

  Explanation:

• Question 132:

  Which term represents the ability to increase the computing capacity of a virtual machine by adding memory or CPUs?

  A. horizontal scaling
  B. agility
  C. elasticity
  D. vertical scaling
  D. vertical scaling

  ---

  Vertical scaling refers to increasing the computing capacity of an existing resource, such as adding more CPUs, memory, or storage to a virtual machine. It is sometimes called "scaling up."

  Horizontal scaling, in contrast, involves adding more instances of a resource, such as multiple virtual machines or app service instances.

  Agility refers to the ability to quickly adapt to changes or deploy resources rapidly.

  Elasticity refers to automatically adjusting resources based on demand, which can involve both vertical and horizontal scaling.

  Incorrect Answer Horizontal scaling: Involves adding additional instances of a resource (e.g., multiple virtual machines) rather than increasing capacity of a single instance.

  Agility: Refers to the ability to quickly adapt, deploy, or change resources, not scaling compute capacity.

  Elasticity: Refers to automatically adjusting resource capacity based on demand, which can include both vertical and horizontal scaling but is not the term specifically for adding CPUs/memory to a VM.

• Question 134:

  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 Advisor provides recommendations on how to improve the security of an azure active directory environment.

  Azure Advisor provides you with a consistent, consolidated view of recommendations for all your Azure resources. It integrates with Azure Security Center to bring you security recommendations. You can get security recommendations from the Security tab on the Advisor dashboard.

  Examples of recommendations include restricting access to virtual machines by configuring Network Security Groups, enabling storage encryption, installing vulnerability assessmentsolutions.

  However, Azure Advisor does not provide recommendations on how to improve the security of an Azure AD environment.

  Box 2: Yes

  Advisor helps you optimize and reduce your overall Azure spend by identifying idle and underutilized resources. You can get cost recommendations from the Cost tab on the Advisor dashboard.

  Box 3: No.

  Azure Advisor does not provide recommendations on how to configure network settings on Azure virtual machines.

• Question 135:

  You need a serverless workflow engine that integrates with SaaS and on-premises systems using connectors. What should you use?

  A. Azure Logic Apps
  B. Azure Functions
  C. Azure Automation
  D. Azure Batch
  A. Azure Logic Apps

  ---

  Logic Apps provide workflow automation with connectors to hundreds of services. Functions provide serverless compute but not workflow-level orchestration with connectors.

• Question 136:

• Question 137:

  What should you use to track the costs of Azure resources?

  A. Tags
  B. usage and quotas
  C. Azure Quickstart templates
  D. budgets
  D. budgets

  ---

  Azure Budgets allows you to monitor and track costs for Azure resources and subscriptions.

  You can set a budget for a specific scope (subscription, resource group, or management group) and receive alerts when spending approaches or exceeds the budgeted amount.

  This is the recommended way to track and control Azure costs over time.

  Incorrect Options:

  Tags: Help organize and categorize Azure resources, but do not track costs directly.

  Usage and quotas: Provide information about resource usage limits and consumption but do not provide cost tracking or alerts.

  Azure Quickstart templates: Used to deploy resources quickly in Azure; they do not track costs.

• Question 139:

  To which cloud models can you deploy physical servers?

  A. private cloud and hybrid cloud only
  B. private cloud only
  C. private cloud, hybrid cloud and public cloud
  D. hybrid cloud only
  A. private cloud and hybrid cloud only

  ---

  Private Cloud: Built on on-premises physical servers.- Provides full control over hardware, security, and networking.-Hybrid Cloud: Combines on-premises private cloud resources with public cloud services.- Physical servers can be deployed on the private side.-Public Cloud: Managed by third-party providers.- Users cannot deploy physical servers; only virtualized resources are available.

  Incorrect Options:

  Private cloud only: Excludes hybrid cloud, which can also include physical servers.

  Private cloud, hybrid cloud, and public cloud: Incorrect; public cloud users cannot deploy physical servers.

  Hybrid cloud only: Excludes private cloud, which also supports physical servers.
