Background
You are a developer for Litware Inc., a SaaS company that provides a solution for managing employee expenses. The solution consists of an ASP.NET Core Web API project that is deployed as an Azure Web App.
Overall architecture
Employees upload receipts for the system to process. When processing is complete, the employee receives a summary report email that details the processing results. Employees then use a web application to manage their receipts and perform any additional tasks needed for reimbursement.
Receipt processing
Employees may upload receipts in two ways:
Uploading using an Azure Files mounted folder
Uploading using the web application
Data Storage
Receipt and employee information is stored in an Azure SQL database.
Documentation
Employees are provided with a getting started document when they first use the solution. The documentation includes details on supported operating systems for Azure File upload, and instructions on how to configure the mounted folder.
Solution details
Users table
Web Application
You enable MSI for the Web App and configure the Web App to use the security principal name WebAppIdentity.
Processing
Processing is performed by an Azure Function that uses version 2 of the Azure Function runtime. Once processing is completed, results are stored in Azure Blob Storage and an Azure SQL database. Then, an email summary is sent to the user with a link to the processing report. The link to the report must remain valid if the email is forwarded to another user.
Logging
Azure Application Insights is used for telemetry and logging in both the processor and the web application.
The processor also has TraceWriter logging enabled. Application Insights must always contain all log messages.
Requirements
Receipt processing
Concurrent processing of a receipt must be prevented.
Disaster recovery
Regional outage must not impact application availability. All DR operations must not be dependent on application running and must ensure that data in the DR region is up to date.
Security
User's SecurityPin must be stored in such a way that access to the database does not allow the viewing of SecurityPins. The web application is the only system that should have access to SecurityPins.
All certificates and secrets used to secure data must be stored in Azure Key Vault.
You must adhere to the principle of least privilege and provide privileges which are essential to perform the intended function.
All access to Azure Storage and Azure SQL database must use the application's Managed Service Identity (MSI).
Receipt data must always be encrypted at rest.
All data must be protected in transit.
User's expense account number must be visible only to logged in users. All other views of the expense account number should include only the last segment, with the remaining parts obscured.
In the case of a security breach, access to all summary reports must be revoked without impacting other parts of the system.
Issues
Upload format issue
Employees occasionally report an issue with uploading a receipt using the web application. They report that when they upload a receipt using the Azure File Share, the receipt does not appear in their profile. When this occurs, they delete the file in the file share and use the web application, which returns a 500 Internal Server error page.
Capacity issue
During busy periods, employees report long delays between the time they upload the receipt and when it appears in the web application.
Log capacity issue
Developers report that the number of log messages in the trace output for the processor is too high, resulting in lost log messages.
Application code
Processing.cs
Database.cs
ReceiptUploader.cs

NEW QUESTION 48
You need to correct the RequestUserApproval Function app error.
What should you do?
- A. Configure the Function app to use an App Service hosting plan. Enable the Always On setting of the hosting plan.
- B. Update line RA13 to use the async keyword and return an HttpRequest object value.
- C. Update the function to be stateful by using Durable Functions to process the request payload.
- D. Update the functionTimeout property of the host.json project file to 15 minutes.
Answer: C
Explanation:
Async operation tracking
The HTTP response mentioned previously is designed to help implement long-running HTTP async APIs with Durable Functions. This pattern is sometimes referred to as the polling consumer pattern.
Both the client and server implementations of this pattern are built into the Durable Functions HTTP APIs.
Function app
You perform local testing for the RequestUserApproval function. The following error message displays:
'Timeout value of 00:10:00 exceeded by function: RequestUserApproval'
The same error message displays when you test the function in an Azure development environment when you run the following Kusto query:
FunctionAppLogs
| where FunctionName = = "RequestUserApproval"

Step 1: Create a Log Analytics workspace.
First create the workspace.
Step 2: Add a VMInsights solution.
Before a Log Analytics workspace can be used with VM insights, it must have the VMInsights solution installed.
Step 3: Install agents on the VM and VM scale set to be monitored.
Prior to onboarding agents, you must create and configure a workspace. Install or update the Application Insights Agent as an extension for Azure virtual machines and VM scalet sets.
Step 4: Create an Application Insights resource
Sign in to the Azure portal, and create an Application Insights resource.

A company is implementing a publish-subscribe (Pub/Sub) messaging component by using Azure Service Bus. You are developing the first subscription application.
In the Azure portal you see that messages are being sent to the subscription for each topic. You create and initialize a subscription client object by supplying the correct details, but the subscription application is still not consuming the messages.
You need to ensure that the subscription client processes all messages.
Which code segment should you use?
- A. await subscriptionClient.AddRuleAsync(new RuleDescription(RuleDescription.DefaultRuleName, new TrueFilter()));
- B. subscriptionClient = new SubscriptionClient(ServiceBusConnectionString, TopicName, SubscriptionName);
- C. subscriptionClient.RegisterMessageHandler(ProcessMessageAsync, messageHandlerOptions);
- D. await subscriptionClient.CloseAsync();
Answer: C
Explanation:
Using topic client, call RegisterMessageHandler which is used to receive messages continuously from the entity. It registers a message handler and begins a new thread to receive messages.
This handler is waited on every time a new message is received by the receiver.
subscriptionClient.RegisterMessageHandler(ReceiveMessagesAsync, messageHandlerOptions); Reference:
