Hotspot Question
You are developing an application that includes two Docker containers.
The application must meet the following requirements:
- The containers must not run as root.
- The containers must be deployed to Azure Container Instances by using a YAML file.
- The containers must share a lifecycle, resources, local network, and
storage volume.
- The storage volume must persist through container crashes.
- The storage volume must be deployed on stop or restart of the
containers.
You need to configure Azure Container Instances for the application.
Which configuration values should you use- To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Hotspot Question
You develop two Python scripts to process data.
The Python scripts must be deployed to two, separate Linux containers running in an Azure Container Instance container group. The containers must access external data by using the Server Message Block (SMB) protocol. Containers in the container group must run only once.
You need to configure the Azure Container Instance.
Which configuration value should you use? To answer, select the appropriate options in the answer area.

A large retail company operates online and physical stores. The company tracks inventory levels in real time to manage stock efficiently across all locations. You develop an Azure Event Grid solution to handle events generated by the inventory management system deployed to Azure.
You need to implement a subscription filter that dynamically adjusts to seasonal changes in product demand.
Which event filter should you use?

• A. A static subject filter that targets events with a subject ending in "/seasonal/inventory"
• B. A subscription filter that uses label filter to include events tagged with seasonal promotional codes
• C. An advanced filter using a Boolean condition that evaluates multiple data fields, including a season field within the event data
• D. A prefix filter on the event type field that matches the current season's name

Case Study 1 - Litware Inc
Backgroun
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
* 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 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 message in the trace output for the processor is too high, resulting in lost log messages.

You have an existing Azure storage account that stores large volumes of data across multiple containers.
You need to copy all data from the existing storage account to a new storage account. The copy process must meet the following requirements:
- Automate data movement.
- Minimize user input required to perform the operation.
- Ensure that the data movement process is recoverable.
What should you use?

• A. AzCopy
• B. .NET Storage Client Library
• C. Azure Storage Explorer
• D. Azure portal
