Regulations require that all divers fill out a health questionnaire every 15 days after each diving job starts.You need to configure the Azure Web Apps so that the instance count scales up when divers are filling out the questionnaire and scales down after they are complete.You need to configure autoscaling.What are two possible auto scaling configurations to achieve this goal? Each correct answer presents a complete solution.NOTE: Each correct selection is worth one point.

• Recurrence profile

• CPU usage-based autoscaling

• Fixed date profile

• Predictive autoscaling

You are updating an application that stores data on Azure and uses Azure Cosmos DB for storage. The application stores data in multiple documents associated with a single username.The application requires the ability to update multiple documents for a username in a single ACID operation.You need to configure Azure Cosmos DB.Which two actions should you perform? Each correct answer presents part of the solution.NOTE: Each correct selection is worth one point.

• Create a collection sharded on username to store documents.

• Configure Azure Cosmos DB to use the Gremlin API.

• Create an unsharded collection to store documents.

• Configure Azure Cosmos DB to use the MongoDB API.

You develop Azure solutions.You must connect to a No-SQL globally-distributed database by using the .NET API.You need to create an object to configure and execute requests in the database.Which code segment should you use?

• A. database_name = 'MyDatabase' database = client.create_database_if_not_exists(id=database_name)

• B. client = CosmosClient(endpoint, key)

• C. container_name = 'MyContainer' container = database.create_container_if_not_exists( id=container_name, partition_key=PartitionKey(path="/lastName"), offer_throughput=400 )

You develop a web application that provides access to legal documents that are stored on Azure Blob Storage with version-level immutability policies. Documents are protected with both time-based policies and legal hold policies. All time-based retention policies have the AllowProtectedAppendWrites property enabled.You have a requirement to prevent the user from attempting to perform operations that would fail only when a legal hold is in effect and when all other policies are expired.You need to meet the requirement.Which two operations should you prevent? Each correct answer presents a complete solution.NOTE: Each correct selection is worth one point.

• adding data to documents

• deleting documents

• creating documents

• overwriting existing documents

You provisioned an Azure Cosmos DB for NoSQL account named account1 with the default consistency level.You plan to configure the consistency level on a per request basis. The level needs to be set for consistent prefix for read and write operations to account1.You need to identify the resulting consistency level for read and write operations.Which levels should you configure? To answer, select the appropriate options in the answer area.NOTE: Each correct selection is worth one point.

• Box 1:strong

  Box2: session

• Box 1:Consistent prefix

  Box2: session

• Box :1session

  Box2: consistent prefix

Answer explanation

You are developing an application to store millions of images in Azure blob storage. The images are uploaded to an Azure blob storage container named companyimages contained in an Azure blob storage account named companymedia. The stored images are uploaded with multiple blob index tags across multiple blobs in the container.You must find all blobs whose tags match a search expression in the container. The search expression must evaluate an index tag named status with a value of final.You need to construct the GET method request URI.How should you complete the URI? To answer, drag the appropriate parameters to the correct request URI targets. Each parameter may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

• Box1:Status='Final'

  Box2:companymedia

  Box3:companyimages

• Box1:companymedia

  Box2companyimages

  Box3:Status = 'Final'

Answer explanation

You are developing a Java application that uses Cassandra to store key and value data. You plan to use a new Azure Cosmos DB resource and the CassandraAPI in the application. You create an Azure Active Directory (Azure AD) group named Cosmos DB Creators to enable provisioning of Azure Cosmos accounts, databases, and containers.The Azure AD group must not be able to access the keys that are required to access the data.You need to restrict access to the Azure AD group.Which role-based access control should you use?

• DocumentDB Accounts Contributor

• Cosmos Backup Operator

• Cosmos DB Operator

• Cosmos DB Account Reader

You are developing a website that will run as an Azure Web App. Users will authenticate by using their Azure Active Directory (Azure AD) credentials.You plan to assign users one of the following permission levels for the website: admin, normal, and reader. A user's Azure AD group membership must be used to determine the permission level.You need to configure authorization.Solution: Configure the Azure Web App for the website to allow only authenticated requests and require Azure AD log on.Does the solution meet the goal?

• Yes

• No

Answer explanation

Instead in the Azure AD application's manifest, set value of the groupMembershipClaims option to All.

You are developing a website that will run as an Azure Web App. Users will authenticate by using their Azure Active Directory (Azure AD) credentials.You plan to assign users one of the following permission levels for the website: admin, normal, and reader. A user's Azure AD group membership must be used to determine the permission level.You need to configure authorization.Solution:✑ Create a new Azure AD application. In the application's manifest, set value of the groupMembershipClaims option to All.✑ In the website, use the value of the groups claim from the JWT for the user to determine permissions.Does the solution meet the goal?

• Yes

• No

Answer explanation

To configure Manifest to include Group Claims in Auth Token1. Go to Azure Active Directory to configure the Manifest. Click on Azure Active Directory, and go to App registrations to find your application:2. Click on your application (or search for it if you have a lot of apps) and edit the Manifest by clicking on it.3. Locate the ג€groupMembershipClaimsג€ setting. Set its value to either ג€SecurityGroupג€ or ג€Allג€. To help you decide which:✑ ג€SecurityGroupג€ - groups claim will contain the identifiers of all security groups of which the user is a member.✑ ג€Allג€ - groups claim will contain the identifiers of all security groups and all distribution lists of which the user is a memberNow your application will include group claims in your manifest and you can use this fact in your code.
