Sample questions

Three questions from the AZ-900 practice bank, with the answer and why each option is right or wrong.

Question 1

A project charter needs a one line definition of cloud computing for readers outside IT. Which definition should the charter use?

  • A. Computing services delivered over the internet
  • B. Computing services run only on servers the company owns
  • C. Software installed from physical media on each computer
  • D. Physical servers shipped to the company for a fixed term

Answer: A. Cloud computing is defined by delivery: computing services that reach the company over the internet. [3]

  • A. Right. Cloud computing is the delivery of computing services over the internet. The charter's line has to name both parts: the services, and the internet as the way they reach the company.
  • B. Wrong. Servers that only the company owns describe a traditional datacenter. The charter needs the services to arrive over the internet.
  • C. Wrong. Installing software from media on each computer sends nothing over the internet, so it can't serve as the charter's definition.
  • D. Wrong. Shipped servers still leave the company running hardware on its own site. The definition the charter needs has the services arrive over the internet.

Question 2

An architect plans a workload for Italy North, an Azure region that has no traditional region pair. What does the region rely on for resiliency in place of a pair?

  • A. A sovereign region isolated from the main instance of Azure
  • B. A region pair in another geography
  • C. Global services that need no region selected
  • D. Availability zones in the region

Answer: D. Some regions, Italy North among them, have no traditional region pair. They rely on availability zones and geo-redundant storage for resiliency. [4]

  • A. Wrong. A sovereign region is an instance of Azure isolated from the main one, used for compliance or legal purposes. It isn't what Italy North relies on in place of a pair.
  • B. Wrong. Italy North doesn't have a traditional region pair, in its own geography or in another. Its resiliency comes from inside the region.
  • C. Wrong. Global services are the ones that don't need a region selected. They aren't part of Italy North, so the region doesn't rely on them in place of a pair.
  • D. Right. Italy North has no traditional region pair and relies on availability zones, along with geo-redundant storage, for resiliency. The architect spreads the workload across the region's zones.

Question 3

An analyst prices one App Service plan, with the same tier and instance count, in two Azure regions under the same subscription. The monthly figures come out different. What explains the gap?

  • A. Pay-as-you-go rates go up with each extra region a team uses.
  • B. Costs such as power, labor and taxes vary from one location to another.
  • C. The resource group that holds the plan sets the rate for its region.
  • D. The subscription type gives each region a usage allowance of its own.

Answer: B. Azure prices most resources by region, because power, labor, taxes and fees cost different amounts in different places. [5]

  • A. Wrong. Under pay-as-you-go a team pays for the resources it uses in a billing cycle. The difference here comes from where each plan runs.
  • B. Right. Power, labor, taxes and fees cost more in some places than others, so the same plan tier and instance count can be priced differently in each region.
  • C. Wrong. Resource groups help keep resources organized. The stem changes the location and nothing else, and location is what moves the price.
  • D. Wrong. Some subscription types include usage allowances, but the stem's gap comes from the two locations. The plan, its settings and the subscription stay the same.
