• Question 121:

  You have an Azure web app that runs in a Premium App Service plan.

  Developers plan to update the app weekly.

  You need to ensure that the app can be twitched from the current version to the new version. The solution must meet the following requirements

  1. Provide the developers with the ability to test the app m Azure prior to switching versions Testing must use the same app instance

  2. Ensure that the app version can be rolled back.

  3. Minimize downtime.

  What should you do?

  A. Create a deployment slot.
  B. Add an instance of the app to the scale set
  C. Copy the App Service plan.
  D. Create an Azure Active Directory (Azure AD) enterprise application
  A. Create a deployment slot.

  ---

  Explanation

  Azure Functions deployment slots allow your function app to run different instances called "slots". Slots are different environments exposed via a publicly available endpoint. One app instance is always mapped to the production slot, and you can swap instances assigned to a slot on demand.

  There are a number of advantages to using deployment slots. The following scenarios describe common uses for slots: Different environments for different purposes: Using different slots gives you the opportunity to differentiate app instances before swapping to production or a staging slot. Easy fallbacks: After a swap with production, the slot with a previously staged app now has the previous production app. If the changes swapped into the production slot aren't as you expect, you can immediately reverse the swap to get your "last known good instance" back.

• Question 125:

  HOTSPOT

  You have the following projects:

  Project1: The development of an app that processes scanned images stored in an Azure Blob Storage account.

  Project2: The migration of an on-premises app that processes log files as they arrive in an SMB file share.

  Project3: The migration of an on-premises app that processes PDF documents stored on a local file system.

  The projects have the requirements shown in the following table.

  

  Project3 does NOT support the use of containers.

  You need to recommend a compute solution for the projects.

  What should you include in the recommendation for each project? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  

  

• Question 126:

  You have an Azure subscription that contains a custom application named Application was developed by an external company named fabric, Ltd. Developers at Fabrikam were assigned role-based access control (RBAV) permissions to the Application components. All users are licensed for the Microsoft 365 E5 plan.

  You need to recommends a solution to verify whether the Faricak developers still require permissions to Application1.

  The solution must the following requirements.

  1. To the manager of the developers, send a monthly email message that lists the access permissions to Application1.

  2. If the manager does not verify access permission, automatically revoke that permission.

  3. Minimize development effort.

  What should you recommend?

  A. In Azure Active Directory (AD) Privileged Identity Management, create a custom role assignment for the Application1 resources
  B. Create an Azure Automation runbook that runs the Get-AzureADUserAppRoleAssignment cmdlet
  C. Create an Azure Automation runbook that runs the Get-AzureRmRoleAssignment cmdlet
  D. In Azure Active Directory (Azure AD), create an access review of Application1
  D. In Azure Active Directory (Azure AD), create an access review of Application1

  ---

  Explanation

  Azure Active Directory (Azure AD) access reviews enable organizations to efficiently manage group memberships, access to enterprise applications, and role assignments. User's access can be reviewed on a regular basis to make sure only the right people have continued access. Have reviews recur periodically: You can set up recurring access reviews of users at set frequencies such as weekly, monthly, quarterly or annually, and the reviewers will be notified at the start of each review. Reviewers can approve or deny access with a friendly interface and with the help of smart recommendations.

  Why are access reviews important?

  "Azure AD enables you to collaborate with users from inside your organization and with external users. Users can join groups, invite guests, connect to cloud apps, and work remotely from their work or personal devices. The convenience of using self-service has led to a need for better access management capabilities."

  An on-premises network gateway can exchange routes with an Azure virtual network gateway using the border gateway protocol (BGP). Using BGP with an Azure virtual network gateway is dependent on the type you selected when you created the gateway. If the type you selected were:

  ExpressRoute: You must use BGP to advertise on-premises routes to the Microsoft Edge router. You cannot create user-defined routes to force traffic to the ExpressRoute virtual network gateway if you deploy a virtual network gateway deployed as type: ExpressRoute. You can use user-defined routes for forcing traffic from the Express Route to, for example, a Network Virtual Appliance.

• Question 130:

  You are planning a storage solution. The solution must meet the following requirements:

  Support at least 500 requests per second.

  Support a large image, video, and audio streams.

  Which type of Azure Storage account should you provision?

  A. standard general-purpose v2
  B. premium block blobs
  C. premium page blobs
  D. premium file shares
  B. premium block blobs

  ---

  Explanation

  Use Azure Blobs if you want your application to support streaming and random access scenarios.

  It's ideal for applications that require high transaction rates or consistent low-latency storage.

  Incorrect:

  Not A: Standard storage accounts has a default maximum request rate per storage account 20,000 requests per second1, but is not optimized for video and audio streams.

  Not C: Page blobs is best suited for random reads and random writes.

  Not D: FileStorage storage accounts (premium) has a maximum concurrent request rate of 100,000 IOPS.

  Maximum file size is 4 TB, but is not optimized for video and audio streams.
