• Question 364:

  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

  Building a data center infrastructure is an example of operational expenditure (OpEx) costs.

  Building a data center infrastructure is capital expenditure, not operation expenditure.

  Box 2: Yes

  OpEx is ongoing costs (costs of operations) such as staff salaries.

  Box 2: Yes

  OpEx is ongoing costs (costs of operations) such as leasing software. If you purchased software as a one-off purchase, that would be CapEx, but leasing software is ongoing so it's OpEx.

  A. billing readers for an Azure subscription only
  B. owners for an Azure subscription only
  C. anyone

  ---

  The public cloud is owned and operated by a cloud provider (like Microsoft Azure) and provides resources that are shared among multiple customers, allowing efficient use of infrastructure.-Other options:

  "The public cloud is owned by the public, NOT a private corporation" . Incorrect. Public cloud services are owned by corporations (Microsoft, Amazon, Google), not the general public.

  "All public cloud resources can be freely accessed by every member of the public" . Incorrect. Access is restricted based on subscriptions and permissions; resources are not publicly open by default.

  "The public cloud is a crowd-sourcing solution that provides corporations with the ability to enhance the cloud" . Incorrect. Public cloud is not a crowd-sourcing platform; it is a commercial service model providing scalable, on-demand resources.

  "A public cloud is a cloud computing model in which a cloud service provider makes resources available to the general public over the Internet. Multiple customers share the infrastructure, and resources are provisioned and managed by the provider."-Microsoft Learn:

  https://learn.microsoft.com/en-us/azure/architecture/cloud-adoption/strategy/overview

  "Public cloud provides a shared infrastructure where multiple organizations can use the same hardware and software resources while maintaining logical isolation and security."

• Question 368:

  HOTSPOT

  Many azure resources require you to specify a ___________ to which they should be deployed.

  Select the answer that correctly completes the sentence.

  

  

  Explanation:

• Question 369:

  Which statement accurately describes the Modern Lifecycle Policy for Azure services?

  A. Microsoft provides mainstream support for a service for five years.
  B. Microsoft provides a minimum of 12 months' notice before ending support for a service.
  C. After a service is made generally available, Microsoft provides support for the service for a minimum of four years.
  D. When a service is retired, you can purchase extended support for the service for up to five years.
  B. Microsoft provides a minimum of 12 months' notice before ending support for a service.

  ---

  Under the Modern Lifecycle Policy, Microsoft promises to give at least 12 months’ prior notification before ending support for a service, if no successor product or service is offered.

  The policy does not guarantee a fixed “5-year mainstream support” period or a fixed “4-year support after GA,” nor does it promise extended paid support for up to five years after retirement.

  Instead, support is maintained continuously while Microsoft offers the service and the customer stays current with licensing and servicing requirements.

  Why other options are incorrect:

  “5 years mainstream support”: That applies to older Fixed-Policy on-premises software, not to services under Modern Lifecycle.

  “Minimum 4 years support after GA”: Modern Lifecycle does not define a fixed support duration after general availability.

  “Extended support up to five years after retirement”: Modern Lifecycle does not guarantee purchasable extended support for retired services.
