Overview -

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 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.

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.

Requirements -

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.

Security -
You have the following security requirements:
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 (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.

CompanyA has multiple on-premises Active Directory forests. CompanyA purchases CompanyB.
CompanyB has multiple on-premises Active Directory forests. CompanyB does not have Foreign Security Principals (FSPs).
You need to connect the Active Directory environments without the use of a staging server and causing minimal disruption to current authentication.
Which Azure AD Connect topology should you use?

  • A. multiple forests, match users
  • B. multiple forests, multiple sync servers to one Azure AD tenant
  • C. multiple forests, single sync server, single Azure AD tenant
  • D. single forest, single Azure AD tenant


Answer : C

Explanation:
Multiple forests, single sync server, users are represented in only one directory
In this environment, all on-premises forests are treated as separate entities. No user is present in any other forest. Each forest has its own Exchange organization, and there's no GALSync between the forests. This topology might be the situation after a merger/acquisition or in an organization where each business unit operates independently. These forests are in the same organization in Azure AD and appear with a unified GAL. In the preceding picture, each object in every forest is represented once in the metaverse and aggregated in the target Azure AD tenant.
Incorrect Answers:
A: Match users uses Foreign Security Principals.
B: Having more than one Azure AD Connect sync server connected to a single Azure AD tenant is not supported.
