  You plan to deploy several Azure virtual machines.

  You need to ensure that the services running on the virtual machines are available if a single data center fails.

  Solution: You deploy the virtual machines to a scale set.

  Does this meet the goal?

  A. Yes
  B. No
  B. No

  ---

  Azure virtual machine scale sets let you create and manage a group of load balanced VMs. The number of VM instances can automatically increase or decrease in response to demand or a defined schedule. Scale sets provide high availability to your applications, and allow you to centrally manage, configure, and update many VMs.

  Virtual machines in a scale set can be deployed across multiple update domains and fault domains to maximize availability and resilience to outages due to data center outages, and planned or unplanned maintenance events.

  Explanation:

  Box 1: Yes

  A single Microsoft account can be used to manage multiple azure subscriptions.

  You can use the same account to manage multiple subscriptions. You can create an additional subscription for your account in the Azure portal. You may want an additional subscription to avoid hitting subscription limits, to create separate environments for security, or to isolate data for compliance reasons.

  Box 2: No

  You cannot merge two subscriptions into a single subscription. However, you can move some Azure resources from one subscription to another. You can also transfer ownership of a subscription and change the billing type for a subscription.

  Box 3: Yes

  A company can have multiple subscriptions and store resources in the different subscriptions. However, a resource instance can exist in only one subscription.

• Question 428:

  Your company has an Azure subscription that contains several resources.

  You need to identify which department is responsible for the cost of each resource.

  What should you use?

  A. tags
  B. alerts
  C. budgets
  A. tags

  ---

  To identify which department is responsible for the cost of each resource in an Azure subscription, you can use tags. Tags are name-value pairs that enable you to categorize resources in a way that is meaningful to your organization. You can use tags to identify resources that belong to a specific department or project, for example.

  Once you have tagged your resources with the appropriate department or project information, you can use the Azure Cost Management + Billing service to generate reports and analyze costs by department or project. This can help you identify areas where you may be able to reduce costs or optimize your resource usage.

  Budgets and alerts can also be useful tools for monitoring and managing costs in an Azure subscription, but they are not specifically designed for identifying which department is responsible for the cost of each resource.

• Question 429:

  HOTSPOT

  _____________ runs application code in azure without requiring a server.

  Select the answer that correctly completes the sentence.

  

  

  Explanation:

  Azure Functions is a serverless solution that allows you to write less code, maintain less infrastructure, and save on costs. Instead of worrying about deploying and maintaining servers, the cloud infrastructure provides all the up-to-date resources needed to keep your applications running.
