NEW QUESTION 1
You need to resolve the delivery API error. What should you do?

• A. Implement simple retry by using the EnableRetryOnFailure feature of Entity Framework.
• B. Implement exponential backoff by using the EnableRetryOnFailure feature of Entity Framework.
• C. Implement the Circuit Breaker pattern by using the EnableRetryOnFailure feature of Entity Framework.
• D. Invoke accustom execution strategy in Entity Framework.

Answer: A

Explanation: Scenario: The Delivery API intermittently throws the following exception:

A useful method to get rid of this error is to use RETRY LOGIC of Entity Framework 1.1.0 services.AddDbContext<DbContext>(options => options.UseSqlServer('yourconnectionstring',
…sqlServerOptionsAction: sqlOptions =>
…{
……sqlOptions.EnableRetryOnFailure(
………maxRetryCount: 5,
………maxRetryDelay: TimeSpan.FromSeconds(30),
………errorNumbersToAdd: new List<int>() { 19 });
…}));
In Retry logic, error 19 is not included. So you have to pass the error code 19 to set retry logic for error code 19.

NEW QUESTION 4
You are creating a collaborative image hosting platform as an ASP.NET MVC web application. Users add, update, and modify images on the platform. Images are stored in Azure Blob storage.
More than one user at a time must be able to modify the same image. You need to implement optimistic concurrency for uploading images.
Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
NOTE: Each correct solution is worth one point.

Answer:

Explanation: Optimistic concurrency means allowing concurrency conflicts to happen, and then reacting appropriately if they do.
For the PUT method, If-Match can be used to prevent the lost update problem. It can check if the modification of a resource that the user wants to upload will not override another change that has been done since the original resource was fetched. If the request cannot be fulfilled, the 412 (Precondition Failed) response is returned.

NEW QUESTION 9
You have an Azure subscription.
You must create a file share with a quota of 2,048 GB. You create the following variables:

In which order should you arrange the Azure CLI commands to develop the solution? To answer, move all the commands from the list of commands to the answer area and arrange them in the correct order.

Answer:

Explanation: Step 1:
Create a resource group
A resource group is a logical container in which Azure resources are deployed and managed. If you don't already have an Azure resource group, you can use the az group create command to create one.
The following example creates a resource group named myResourceGroup in the East US location: az group create --name myResourceGroup --location eastus
Step 2:
Create a storage account
The following example creates a storage account named mystorageaccount<random number> by using the az storage account create command, and then puts the name of that storage account in the $STORAGEACCT variable.
STORAGEACCT=$(az storage account create
--resource-group "myResourceGroup"
--name "mystorageacct$RANDOM"
--location eastus
--sku Standard_LRS
--query "name" | tr -d '"') Step 3:
Get the storage account key
Storage account keys control access to resources in a storage account. The keys are automatically created when you create a storage account. You can get the storage account keys for your storage account by using the az storage account keys list command:
STORAGEKEY=$(az storage account keys list
--resource-group "myResourceGroup"
--account-name $STORAGEACCT
--query "[0].value" | tr -d '"') Step 4:
Now, you can create your Azure file share. Create file shares by using the az storage share create command. This example creates an Azure file share named myshare:
az storage share create
--account-name $STORAGEACCT
--account-key $STORAGEKEY
--name "myshare" References:

• I. Create a Shared Access policy for Send permissions and another for Receive permissions.

Answer: C

Explanation: To begin using Service Bus messaging entities in Azure, you must first create a namespace with a name that is unique across Azure. A namespace provides a scoping container for addressing Service Bus resources within your application.
When you publish an application through Azure Active Directory Application Proxy, you create an external URL for your users to go to when they're working remotely. This URL gets the default domain yourtenant.msappproxy.net.

Answer:

Explanation: FutureOrders: SQLFilter HighPriortyOrders: CorrelationFilter CorrelationID only InternationalOrders: SQLFilter
Country NOT USA requires an SQL Filter
HighQuantityOrders: SQLFilter
Need to use relational operators so an SQL Filter is needed. AllOrders: No Filter
SQL Filter: SQL Filters - A SqlFilter holds a SQL-like conditional expression that is evaluated in the broker against the arriving messages' user-defined properties and system properties. All system properties must be prefixed with sys. in the conditional expression. The SQL-language subset for filter conditions tests for the existence of properties (EXISTS), as well as for null-values (IS NULL), logical NOT/AND/OR, relational operators, simple numeric arithmetic, and simple text pattern matching with LIKE.
Correlation Filters - A CorrelationFilter holds a set of conditions that are matched against one or more of an arriving message's user and system properties. A common use is to match against the CorrelationId property, but the application can also choose to match against ContentType, Label, MessageId, ReplyTo, ReplyToSessionId, SessionId, To, and any user-defined properties. A match exists when an arriving message's value for a property is equal to the value specified in the correlation filter. For string expressions, the comparison is case-sensitive. When specifying multiple match properties, the filter combines them as a logical AND condition, meaning for the filter to match, all conditions must match.
Boolean filters - The TrueFilter and FalseFilter either cause all arriving messages (true) or none of the arriving messages (false) to be selected for the subscription.

NEW QUESTION 19
A company is developing a software as a service (SaaS) solution in Azure for other business to manage customers. The solution includes the following Azure SQL Database instances. Customer data exists in all databases.

Customers may request that the company remove data that relates to the customer. If a customer makes a deletion request, all details from the customer must be removed from the solution. All deletions for a customer must occur in one distributed transaction that includes the CRM, ERP, and Marketing databases.
You need to activate support for transactions over multiple databases on the same logical server and activate support for transactions over multiple servers.
Which actions and Azure PowerShell command should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Answer:

Explanation: Box 1: Use a transaction scope
The TransactionScope class establishes an ambient transaction in .NET. (An “ambient transaction” is one that lives in the current thread.) All connections opened within the TransactionScope participate in the transaction. If different databases participate, the transaction is automatically elevated to a distributed transaction.
Box 2: New-AzureRmSqlServerCommunicationLink
New-AzureRmSqlServerCommunicationLink: Use this cmdlet to create a new communication relationship between two logical servers in Azure SQL DB. The relationship is symmetric which means both servers can initiate transactions with the other server.
