Microsoft AZ-900 Online Questions & Answers

• Question 391:

  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: Yes

  Data that is copied to an azure storage account is maintained automatically in at least three copies.

  There are different replication options available with a storage account. The ‘minimum’ replication option is Locally Redundant Storage (LRS). With LRS, data is replicated synchronously three times within the primary region.

  Box 2: No

  Data is not backed up automatically to another Azure Data Center although it can be depending on the replication option configured for the account. Locally Redundant Storage (LRS) is the default which maintains three copies of the data in the data center.

  Geo-redundant storage (GRS) has cross-regional replication to protect against regional outages. Data is replicated synchronously three times in the primary region, then replicated asynchronously to the secondary region.

  Box 3: No

  The limits are much higher than that. The current storage limit is 2 PB for US and Europe, and 500 TB for all other regions (including the UK) with no limit on the number of files.

• Question 392:

  Your company plans to request an architectural review of an Azure environment from Microsoft.

  The company currently has a Basic support plan.

  You need to recommend a new support plan for the company. The solution must minimize costs.

  Which support plan should you recommend?

  A. Premier
  B. Developer
  C. Professional Direct
  D. Standard
  A. Premier

  ---

  The Developer support plan provides access to technical support and architectural guidance for non-production environments at the lowest cost above Basic.

  It allows submitting support requests and requesting architectural guidance, making it suitable for requesting an architectural review while minimizing costs.

  https://learn.microsoft.com/en-us/azure/azure-supportability/plans

  "The Developer support plan is designed for trial and non-production environments and provides guidance on architecture and development best practices at minimal cost."

  Why the Other Options Are Incorrect:

  Premier-Incorrect.-Premier provides the highest level of support and dedicated technical account managers; it is expensive and not cost-minimizing.

• Question 393:

  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: Yes

  Most services go to private preview then public preview before being released to general availability.

  The private preview is only available to certain Azure customers for evaluation purposes. The public preview is available to all Azure customers.

  Box 2: No

  Azure services in public preview can be managed using the regular management tools: Azure Portal, Azure CLI and PowerShell.

  Box 3: No

  Services in private or public preview are usually offered at reduced costs. However, the costs increase, not decrease when the services are released to general availability.

• Question 394:

  You have 50 virtual machines hosted on-premises and 50 virtual machines hosted in Azure. The on-premises virtual machines and the Azure virtual machines connect to each other.

  Which type of cloud model is this?

  A. hybrid
  B. private
  C. public
  A. hybrid

  ---

  A hybrid cloud combines on-premises infrastructure with cloud resources and allows communication between both environments.

  Why the other answers are wrong:

  private:

  Private cloud uses only company-owned or on-premises infrastructure.

  This scenario includes Azure, so it is not private.

  public:

  Public cloud uses only cloud-based resources.

  This scenario includes on-premises virtual machines, so it is not public.

• Question 396:

  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.

  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 two or more regions.

  Does this meet the goal?

  A. Yes
  B. No
  A. Yes

  ---

  By deploying the virtual machines to two or more regions, you are deploying the virtual machines to multiple datacenters. This will ensure that the services running on the virtual machines are available if a single data center fails.

  Azure operates in multiple datacenters around the world. These datacenters are grouped in to geographic regions, giving you flexibility in choosing where to build your applications. You create Azure resources in defined geographic regions like 'West US', 'North Europe', or 'Southeast Asia'. You can review the list of regions and their locations. Within each region, multiple datacenters exist to provide for redundancy and availability.

• Question 397:

  HOTSPOT

  How should you calculate the monthly uptime percentage? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  

  

  Explanation:

  "Maximum Available Minutes" is the total accumulated minutes during a billing month .

  "Downtime" is the total accumulated minutes that are part of Maximum Available Minutes where a system is unavailable.

  "Monthly Uptime Percentage" for a service is calculated as Maximum Available Minutes less Downtime divided by Maximum Available Minutes x 100.

  Monthly Uptime Percentage is represented by the following formula:

  Monthly Uptime % = (Maximum Available Minutes-Downtime) / Maximum Available Minutes x 100.

• Question 399:

  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

  Adding resource groups in an azure subscription generates additional costs.

  Resource groups are logical containers for Azure resources. You do not pay for resource groups.

  Box 2: No

  Data ingress over a VPN is data ‘coming in’ to Azure over the VPN. You are not charged data transfer costs for data ingress.

  Box 3: Yes

  Data egress over a VPN is data ‘going out’ of Azure over the VPN. You are charged for data egress.

• Question 400:

  Your company has 10 departments.

  The company plans to implement an Azure environment.

  You need to ensure that each department can use a different payment option for the Azure services it consumes.

  What should you create for each department?

  A. a reservation
  B. a subscription
  C. a resource group
  D. a container instance
  B. a subscription

  ---

  There are different payment options in Azure including pay-as-you-go (PAYG), Enterprise Agreement (EA), and Microsoft Customer Agreement (MCA) accounts.

  Your Azure costs are `per subscription'. You are charged monthly for all resources in a subscription. Therefore, to use different payment options per department, you will need to create a separate subscription per department. You can create multiple subscriptions in a single Azure Active Directory tenant.

  Incorrect Answers:

  A: A reservation is where you commit to a resource (for example a virtual machine) for one or three years. This gives you a discounted price on the resource for the reservation period. Reservations do not provide a way to use different payment options per department.

  C: A resource group is a logical container for Azure resources. You can view the total cost of all the resources in a resource group. However, resource groups do not provide a way to use different payment options per department.

  D: A container instance is an Azure resource used to run an application. Container instances do not provide a way to use different payment options per department.
