To start the case study
To display the first question in this case study, click the Next button. Use the buttons in the left pane to explore the content of the case study before you answer the questions. Clicking these buttons displays information such as business requirements, existing environment, and problem statements. If the case study has an All Information tab. note that the information displayed is Identical to the information displayed on the subsequent tabs. When you are ready to answer a question, click the Question button to return to the question.

You are a developer for Proseware, Inc. You are developing an application that applies a set of governance policies for Proseware’s internal services, external services, and applications. The application will also provide a shared library for common functionality.

You develop and deploy a stateful ASP.NET Core 2.1 web application named Policy service to an Azure App Service Web App. The application reacts to events from Azure Event Grid and performs policy actions based on those events.
The application must include the Event Grid Event ID field in all Application Insights telemetry.
Policy service must use Application Insights to automatically scale with the number of policy actions that it is performing.

Log policy
All Azure App Service Web Apps must write logs to Azure Blob storage. All log files should be saved to a
container named logdrop. Logs must remain in the container for 15 days.

Authentication events
Authentication events are used to monitor users signing in and signing out. All authentication events must be processed by Policy service. Sign outs must be processed as quickly as possible.

PolicyLib
You have a shared library named PolicyLib that contains functionality common to all ASP.NET Core web services and applications.
The PolicyLib library must:
- Exclude non-user actions from Application Insights telemetry.
- Provide methods that allow a web service to scale itself.
- Ensure that scaling actions do not disrupt application usage.

Anomaly detection service
You have an anomaly detection service that analyzes log information for anomalies. It is implemented as an Azure Machine Learning model. The model is deployed as a web service.
If an anomaly is detected, an Azure Function that emails administrators is called by using an HTTP WebHook.

Health monitoring
All web applications and services have health monitoring at the /health service endpoint.

Policy loss
When you deploy Policy service, policies may not be applied if they were in the process of being applied during the deployment.

Performance issue
When under heavy load, the anomaly detection service undergoes slowdowns and rejects connections.

Notification latency
Users report that anomaly detection emails can sometimes arrive several minutes after an anomaly is detected.

Relevant portions of the app files are shown below. Line numbers are included for reference only and include a two-character prefix that denotes the specific file to which they belong.

When you are ready to answer a question, click the Question button to return to the question. 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.

Users table




Web Application
You enable MS! for the Web App and configure the Web App to use the security principal name.

Processing
Processing is performed by an Azure Function that uses version 2 of the Azure Function runtime. Once processing 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.

Receipt processing
Concurrent processing of a receipt must be prevented.

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.

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.
- Users' 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 Least Privilege Principal.
- All access to Azure Storage and Azure SQL database must use the application's Managed Service Identity
- 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 pans of the system.

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.
















You need to ensure that the upload format issue is resolved.
What code should you add at line RU14? To answer, drag the appropriate code fragments to the correct locations. Each code fragment 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.
